Application of 534-03-2In 2019 ,《Immunosuppressive effect of a non-proteinogenic amino acid from Streptomyces through inhibiting allogeneic T cell proliferation》 was published in Bioscience, Biotechnology, and Biochemistry. The article was written by Yashiro, Takuya; Sakata, Fumiya; Sekimoto, Takahiro; Shirai, Tomohiro; Hasebe, Fumihito; Matsuda, Kenichi; Kurosawa, Sumire; Suzuki, Shodai; Nagata, Kazuki; Kasakura, Kazumi; Nishiyama, Makoto; Nishiyama, Chiharu. The article contains the following contents:

The immunosuppressive activity of myriocin (ISP-1), a lead compound of fingolimod (FTY720), is derived from its 2-amino-1,3-propandiol structure. A non-proteinogenic amino acid, (2S,6R)-diamino-(5R,7)-dihydroxy-heptanoic acid (DADH), that contains this structure, was recently identified as a biosynthetic intermediate of a dipeptide secondary metabolite, vazabitide A, in Streptmyces sp. SANK 60404; however its effect on adaptive immunity has not yet been examined In this study, we examined whether DADH suppresses mixed lymphocyte reaction using mouse bone marrow-derived dendritic cells (BMDCs) and allogeneic splenic T cells. Although T cell proliferation induced by crosslinking CD3 and CD28 were not suppressed by DADH unlike ISP-1, the pre-incubation of BMDCs with DADH but not ISP-1 significantly decreased allogeneic CD8+ T cell expansion. Based on these results, we concluded that DADH suppresses DC-mediated T cell activation by targeting DCs. The experimental part of the paper was very detailed, including the reaction process of 2-Aminopropane-1,3-diol(cas: 534-03-2Application of 534-03-2)

2-Aminopropane-1,3-diol(cas: 534-03-2) belongs to anime. Amines characteristically form salts with acids; a hydrogen ion, H+, adds to the nitrogen. With the strong mineral acids (e.g., H2SO4, HNO3, and HCl), the reaction is vigorous. Salt formation is instantly reversed by strong bases such as NaOH. Neutral electrophiles (compounds attracted to regions of negative charge) also react with amines; alkyl halides (R′X) and analogous alkylating agents are important examples of electrophilic reagents.Application of 534-03-2

Synthetic Route of C3H9NO2In 2019 ,《Synthesis of Porphyrinoids, BODIPYs, and (Dipyrrinato)ruthenium(II) Complexes from Prefunctionalized Dipyrromethanes》 appeared in European Journal of Organic Chemistry. The author of the article were Hohlfeld, Benjamin F.; Flanagan, Keith J.; Kulak, Nora; Senge, Mathias O.; Christmann, Mathias; Wiehe, Arno. The article conveys some information:

The introduction of functional groups into the meso-position of dipyrromethanes, boron-dipyrromethenes (BODIPYs) and porphyrinoids, is of fundamental importance in designing such dye systems for material sciences or photomedicine. One route that proved to be particularly useful in this respect is the nucleophilic aromatic substitution (SNAr) on porphyrinoids and their precursors carrying electron-withdrawing substituents. To further expand this methodol., the potential of the 4-fluoro-3-nitrophenyl and the 3,4,5-trifluorophenyl moieties for the synthesis of functionalized dipyrromethanes, BODIPYs, and porphyrinoids was evaluated. The 3,4,5-trifluorophenyl moiety proved not to be applicable in the SNAr with nucleophiles. The introduction of the 4-fluoro-3-nitrophenyl group, however, allowed fast and efficient SNAr with various amine nucleophiles. The synthesized 4-amino-3-nitrophenyl-substituted dipyrromethanes were successfully applied in the synthesis BODIPYs and were tested in the synthesis of “”trans””-A2B2 porphyrins and A2B corroles. Furthermore, the dipyrromethanes – after oxidation to the dipyrromethenes – are suitable ligands for metal ions giving access to functionalized ruthenium(II) metal complexes.2-Aminopropane-1,3-diol(cas: 534-03-2Synthetic Route of C3H9NO2) was used in this study.

Aniline, ethanolamines, and several other amines are major industrial commodities used in making rubber, dyes, pharmaceuticals, and synthetic resins and fibres and for a host of other applications. Most of the numerous methods for the preparation of amines may be broadly divided into two groups: (1) chemical reduction (replacement of oxygen with hydrogen atoms in the molecule) of members of several other classes of organic nitrogen compounds and (2) reactions of ammonia or amines with organic compounds.Synthetic Route of C3H9NO2

Noroozi, Javad; Smith, William R. published their research in Journal of Chemical Information and Modeling in 2021. The article was titled 《Force-Field-Based Computational Study of the Thermodynamics of a Large Set of Aqueous Alkanolamine Solvents for Post-Combustion CO2 Capture》.Related Products of 534-03-2 The article contains the following contents:

The ability to predict the thermodn. properties of amine species in CO2-loaded aqueous solutions, including their deprotonation (pKa) and carbamate to bicarbonate reversion (pKc) equilibrium constants and their corresponding standard reaction enthalpies, is of critical importance for the design of improved carbon capture solvents. In this study, we used isocoulombic forms of both reactions to determine these quantities for a large set of aqueous alkanolamine solvent systems. Our hybrid approach involves using classical mol. dynamics simulations with the general amber force field (GAFF) and semi-empirical AM1-BCC charges (GAFF/AM1-BCC) in the solution phase, combined with high-level composite quantum chem. ideal-gas calculations We first determined a new force field (FF) for the hydronium ion (H3O+) by matching to the single exptl. pKa data point for the well-known monoethanolamine system at 298.15 K. We then used this FF to predict the pKa values for 76 other amines at 298.15 K and for all 77 amines at elevated temperatures Addnl., we indirectly relate the H3O+ hydration free energy to that of H+ and provide expressions for intrinsic hydration free energy and enthalpy of the proton. Using the derived H3O+ FF, we predicted the pKa values of a diverse set of alkanolamines with an overall average absolute deviation of less than 0.72 pKa units. Furthermore, the derived H3O+ FF is able to predict the protonation enthalpy of these amines when used with the GAFF. We also predicted the carbamate reversion constants of the primary and secondary amine species in the data set and their corresponding standard heats of reaction, which we compared with the scarcely available exptl. data, which are often subject to significant uncertainty. Finally, we also described the influence of electronic and steric effects of different mol. fragments/groups on the stabilities of the carbamates.

And the article was published in Frontiers in Chemistry (Lausanne, Switzerland) in 2019. SDS of cas: 534-03-2 The author mentioned the following in the article:

A novel Al3+ chemosensor NPA was designed and synthesized on basis of the mechanism of ICT and CHEF. Upon addition of Al3+, the probe NPA displayed a bright green fluorescence under UV radiation and visual color change from yellow to colorless. Spectrum titrations showed that NPA could be recognized as a fluorescent turn-on probe with 10-8 M detection level. The probe was successfully applied in real water sample and test paper. More important, NPA-Al3+ complex were used as a fluorescent turn-off probe for the detection of ClO- with the detection as low as 2.34 ×x 10-8 M. The performance of NPA to Al3+ and NPA-Al3+ complex to ClO- demonstrated that NPA could be served as a sensitive probe and exhibit INHIBIT logic gate behavior with Al3+ and ClO- as inputs.

HPLC of Formula: 534-03-2. The article was titled 《Solubility of CO2 in aqueous 2-amino-1, 3-propanediol (Serinol) at elevated pressures》. The information in the text is summarized as follows:

In this work, aqueous 2-amino-1, 3-propanediol solution (serinol) was investigated as a potential solvent for CO2 capture from different gas streams. Prior to CO2 solubility experiments, a qual. prediction technique was performed on serinol to ensure its potentiality as a CO2 capture solvent. This was done using COSMO-RS approach based on quantum chem. calculations Based on this approach, serinol showed good affinity towards hydrogen-bond donors which proved to be beneficial in developing intermol. interaction between serinol and CO2. The solubility of CO2 in serinol was then investigated at serinol concentrations ranging from 1 M to 3 M, temperatures ranging from 313.15 K to 353.15 K and CO2 partial pressures ranging from 1034.31 kPa to 2068.43 kPa. The solubility of CO2 in serinol reached a highest value of 1.64 mol of CO2/mol of serinol when the serinol concentration was 1 M, at 313.15 K and 2068.43 kPa. Meanwhile, Henry’s law constant of CO2 in serinol was calculated using N2O analogy at 313.15 K and 333.15 K for molar concentrations of 1 M and 3 M of serinol. Results showed that the phys. solubility of CO2 in serinol increased as the temperature and the concentration of the solution decreased. The lowest value of Henry’s law constant of CO2 was 599.4 kPa·m3·kmol-1, for 1 M of serinol at 313.15 K.

Electric Literature of C3H9NO2In 2019 ,《Novel fatty acid-based pH-responsive nanostructured lipid carriers for enhancing antibacterial delivery》 was published in Journal of Drug Delivery Science and Technology. The article was written by Osman, Nawras; Omolo, Calvin A.; Gannimani, Ramesh; Waddad, Ayman Y.; Rambharose, Sanjeev; Mocktar, Chunderika; Singh, Sanil; Parboosing, Raveen; Govender, Thirumala. The article contains the following contents:

The present study is aimed at the employment of novel fatty acid derived lipids for the preparation of pH-responsive nanostructured lipid carriers (NLCs) for vancomycin (VCM) i.v. delivery against resistant and sensitive Staphylococcus aureus bacteria. Two branched lipids [stearic acid derived solid lipid and oleic acid derived liquid lipid] were synthesized, characterized and used to fabricate NLCs by hot homogenization technique. Particle size, polydispersity index, zeta potential and encapsulation efficiency were 225.2 ± 9.1 nm, 0.258 ± 0.02, -9.2 ± 2.7 mV and 88.7 ± 13.12%, resp. An understanding of drug encapsulation efficiencies and formation of the NLCs were supported by in silico studies. In vitro antibacterial activity revealed that VCM loaded-NLCs had higher activity against methicillin-susceptible and resistant Staphylococcus aureus than the bare VCM. Cell viability study showed that NLCs had 2.5-fold better killing percentage than the bare drug at similar concentrations Furthermore, the in vivo efficacy of VCM loaded-NLCs was assessed in a mouse model of MRSA skin infection. MRSA CFU load of the skin treated with NLCs was 37-fold lower than bare VCM (p < 0.05). This novel pH-responsive NLCs may, therefore, show potential for efficient and enhanced antibiotic delivery.

In 2022,Eshaghi Gorji, Zahra; Ebrahimpoor Gorji, Ali; Riahi, Siavash published an article in Chemical Engineering Research and Design. The title of the article was 《A structure-property model for the prediction of pKa values of different amines in the CO2 capture process of concern to the prediction of thermodynamic properties》.Computed Properties of C3H9NO2 The author mentioned the following in the article:

In this study, Quant. Structure-Property Relationship (QSPR) method has been applied on a dataset including the pKa values of 21 different structures (20 amines and ammonia) at four temperatures in the post-combustion-capture process using QSARINS. QSPR models have been accomplished in two situations, called fixed and unfixed temperatures In the fixed temperatures, four predictive models with one descriptor have been sep. developed at each temperature Besides, thermodn. properties have been calculated by the van′t Hoff equation using predicted pKa values. In the unfixed temperatures, two general models were developed which take into account the effects of mol. structure and temperature, simultaneously. The predicted pKa values and calculated Gibbs free energy have a good consistency with related values in the literature. The reliability of each developed model has been examined using external assessments. The values of some statistical parameters such as R2 = 0.89 and AARD% = 2.68 verify the prediction capability of models.

In 2022,Elberskirch, Linda; Le Harzic, Ronan; Scheglmann, Dietrich; Wieland, Gerhard; Wiehe, Arno; Mathieu-Gaedke, Maria; Golf, Hartwig R. A.; von Briesen, Hagen; Wagner, Sylvia published an article in European Journal of Pharmaceutical Sciences. The title of the article was 《A HET-CAM based vascularized intestine tumor model as a screening platform for nano-formulated photosensitizers》.Application of 534-03-2 The author mentioned the following in the article:

The development of new tumor models for anticancer drug screening is a challenge for preclin. research. Conventional cell-based in vitro models such as 2D monolayer cell cultures or 3D spheroids allow an initial assessment of the efficacy of drugs but they have a limited prediction to the in vivo effectiveness. In contrast, in vivo animal models capture the complexity of systemic distribution, accumulation, and degradation of drugs, but visualization of the individual steps is challenging and extracting quant. data is usually very difficult. Furthermore, there are a variety of ethical concerns related to animal tests. In accordance with the 3Rs principles of Replacement, Reduction and Refinement, alternative test systems should therefore be developed and applied in preclin. research. The Hen’s egg test on chorioallantoic membrane (HET-CAM) model provides the generation of vascularized tumor spheroids and therefore, is an ideal test platform which can be used as an intermediate step between in vitro anal. and preclin. evaluation in vivo. We developed a HET-CAM based intestine tumor model to investigate the accumulation and efficacy of nano-formulated photosensitizers. Irradiation is necessary to activate the phototoxic effect. Due to the good accessibility of the vascularized tumor on the CAM, we have developed a laser irradiation setup to simulate an in vivo endoscopic irradiation The study presents quant. as well as qual. data on the accumulation and efficacy of the nano-formulated photosensitizers in a vascularized intestine tumor model.

《Self-assembly of pH-sensitive micelles for enhanced delivery of doxorubicin to melanoma cells》 was published in Journal of Drug Delivery Science and Technology in 2020. These research results belong to Long, Miaomiao; Liu, Shenhuan; Shan, Xiaotian; Mao, Jing; Yang, Fuwei; Wu, Xiaoyu; Qiu, Lipeng; Chen, Jinghua. Name: 2-Aminopropane-1,3-diol The article mentions the following:

Polymeric micelles have attracted much attention in the field of anticancer drug delivery system because of their special properties. However, the slow drug release rate of micelles after reaching tumor cells is still considered to be a major problem. Therefore, we constructed a new orthoester-based pH-sensitive polyethylene glycol-hydroxydodecanoic acid (PAE) polymer to form doxorubicin-loaded micelles (DOX/PAE). DOX/PAE micelles with uniform particle size showed pH-sensitive drug release behavior in vitro. And the in vitro cytotoxicity studies showed that blank PAE micelles were nontoxic to cells while DOX/PAE micelles could inhibit the growth of tumor cells in a concentration-dependent manner. Furthermore, cellular uptake studies showed that DOX/PAE micelles were uptaken by tumor cells and transported into the nucleus to achieve the effect of killing tumor cells. The results of the uptake mechanism showed that clathrin and macrophage mediated endocytic pathways played important roles in internalization of DOX/PAE micelles. Altogether, the above results show that pH-sensitive PAE micelles have potential in anticancer drug delivery. In addition to this study using 2-Aminopropane-1,3-diol, there are many other studies that have used 2-Aminopropane-1,3-diol(cas: 534-03-2Name: 2-Aminopropane-1,3-diol) was used in this study.

In 2019,Biochimica et Biophysica Acta, Biomembranes included an article by Sivaramakrishna, D.; Prasad, Muvva D.; Swamy, Musti J.. Name: 2-Aminopropane-1,3-diol. The article was titled 《A homologous series of apoptosis-inducing N-acylserinols: Thermotropic phase behavior, interaction with cholesterol and characterization of cationic N-myristoylserinol-cholesterol-CTAB niosomes》. The information in the text is summarized as follows:

N-Acylserinols (NASOHs) exhibit anti-cancer activity by elevating ceramide levels, and/or by activating proapoptotic effectors. In the present work we investigated the thermotropic phase behavior and supramol. organization of a homologous series of NASOHs (number of C-atoms in the acyl chain, n = 8-18), and the interaction of N-myristoylserinol (NMSOH) with cholesterol, and characterized cationic niosomes made up of NMSOH, cholesterol and cetyltrimethylammonium bromide (CTAB). Differential scanning calorimetric studies revealed that NASOHs exhibit a major chain-melting phase transition in both dry and hydrated states. The thermodn. parameters, transition enthalpy and entropy show linear dependence on the acyl chain length in the dry state, but exhibit odd-even alternation in the hydrated state. Powder X-ray diffraction studies revealed that NASOHs adopt a tilted bilayer structure, wherein the bilayer repeat distances (d-spacings) also showed odd-even alteration, with even-chainlength compounds exhibiting slightly higher d-spacings. Studies on the interaction between NMSOH and cholesterol revealed that both lipids mix well with up to 55 mol% cholesterol, whereas phase separation was observed at higher cholesterol content. The transition enthalpy corresponding to the NMSOH-cholesterol complex increases up to 55 mol% cholesterol and decreases at higher cholesterol content. Presence of the cationic surfactant CTAB affects the phase behavior, fluidity and size of the NMSOH-cholesterol (45,55, mol/mol) niosomes, with unilamellar vesicles of about 85 (±20) nm in diameter being obtained at 10 mol% CTAB. These results provide a thermodn. and structural basis for further investigations on these cationic niosomes towards their use in drug delivery applications, especially for anticancer drugs.
