Modulation of the secondary structures of peptides gives rise to a range of natural peptide-based soft materials with outstanding mech. properties. Here, we discuss detailed insights on how the secondary structure of tailor-made polypeptides governs the mech. properties of polymeric hydrogels. To this end, we developed a series of polymeric hydrogels crosslinked by poly(3-propyl-acrylate-glutamine) with tailorable secondary structures-α-helixes and random coils. Interestingly, the hydrogels crosslinked by the α-helical crosslinker exhibit a high tensile strength and toughness because of the cooperative intramol. hydrogen bonding along the polypeptide backbone. Furthermore, the α-helixes endow the hydrogels with high resilience and rapid recovery because of their reversible cooperative hydrogen bonding. In contrast, the hydrogels crosslinked by the random coil crosslinker show inferior tensile strength and toughness. Our study establishes quant. nanoscale/macroscale structure-property relationships in polymeric hydrogels and has important implications for the rational design of soft materials using polypeptides with a specific secondary structure.

Quality Control of 3-Aminopropan-1-olIn 2021 ,《High-Contrast CXCR4-Targeted 18F-PET Imaging Using a Potent and Selective Antagonist》 appeared in Molecular Pharmaceutics. The author of the article were Kwon, Daniel; Lozada, Jerome; Zhang, Zhengxing; Zeisler, Jutta; Poon, Richel; Zhang, Chengcheng; Roxin, Aron; Lin, Kuo-Shyan; Perrin, David; Benard, Francois. The article conveys some information:

C-X-C chemokine receptor 4 (CXCR4) is highly expressed in cancers, contributing to proliferation, metastasis, and a poor prognosis. The noninvasive imaging of CXCR4 can enable the detection and characterization of aggressive cancers with poor outcomes. Currently, no 18F-labeled CXCR4 positron emission tomog. (PET) radiotracer has demonstrated imaging contrast comparable to [68Ga]Ga-Pentixafor, a CXCR4-targeting radioligand. We, therefore, aimed to develop a high-contrast CXCR4-targeting radiotracer by incorporating a hydrophilic linker and trifluoroborate radioprosthesis to LY2510924, a known CXCR4 antagonist. A carboxy-ammoniomethyl-trifluoroborate (PepBF3) moiety was conjugated to the LY2510924-derived peptide possessing a triglutamate linker via amide bond formation to obtain BL08, whereas an alkyne ammoniomethyl-trifluoroborate (AMBF3) moiety was conjugated using the copper-catalyzed [3+2] cycloaddition click reaction to obtain BL09. BL08 and BL09 were radiolabeled with [18F]fluoride ion using 18F-19F isotope exchange. Pentixafor was radiolabeled with [68Ga]GaCl3. Side-by-side PET imaging and biodistribution studies were performed on immunocompromised mice bearing Daudi Burkitt lymphoma xenografts. The biodistribution of [18F]BL08 and [18F]BL09 showed tumor uptake at 2 h postinjection (p.i.) (5.67 ± 1.25%ID/g and 5.83 ± 0.92%ID/g, resp.), which were concordant with the results of PET imaging. [18F]BL08 had low background activity, providing tumor-to-blood, -muscle, and -liver ratios of 72 ± 20, 339 ± 81, and 14 ± 3 (2 h p.i.), resp. [18F]BL09 behaved similarly, with ratios of 64 ± 20, 239 ± 72, and 17 ± 3 (2 h p.i.), resp. This resulted in high-contrast visualization of tumors on PET imaging for both radiotracers. [18F]BL08 exhibited lower kidney uptake (2.2 ± 0.5%ID/g) compared to [18F]BL09 (7.6 ± 1.0%ID/g) at 2 h p.i. [18F]BL08 and [18F]BL09 demonstrated higher tumor-to-blood, -muscle, and -liver ratios compared to [68Ga]Ga-Pentixafor (18.9 ± 2.7, 95.4 ± 36.7, and 5.9 ± 0.7 at 2 h p.i., resp.). In conclusion, [18F]BL08 and [18F]BL09 enable high-contrast visualization of CXCR4 expression in Daudi xenografts. Based on high tumor-to-organ ratios, [18F]BL08 may prove a valuable new tool for CXCR4-targeted PET imaging with potential for translation. The use of a PepBF3 moiety is a new approach for the orthogonal conjugation of organotrifluoroborates for 18F-labeling of peptides.3-Aminopropan-1-ol(cas: 156-87-6Quality Control of 3-Aminopropan-1-ol) was used in this study.

Application of 156-87-6. The article was titled 《Phosphorus-nitrogen compounds. Part 42. The comparative syntheses of 2-cis-4-ansa(N/O) and spiro(N/O) cyclotetraphosphazene derivatives: spectroscopic and crystallographic characterization, antituberculosis and cytotoxic activity studies》. The information in the text is summarized as follows:

The reaction of N4P4Cl8 (1) with one equimolar amount of the sodium salt of an N/O donor-type bidentate ligand (2) afforded two kinds of derivatives, namely, mono-ferrocenyl-2-cis-4-dichloro-ansa- (2,4-ansa; 3) and mono-ferrocenyl-spiro- (spiro; 4) hexachlorocyclotetraphosphazenes. The reaction yield (35%) of 4 was significantly larger than that of 3 (14%). The 2,4-ansa compound (3) was reacted with excess secondary amines to produce 2-cis-4-dichloro-ansa-cyclotetraphosphazenes (3a-3d). On the other hand, the spiro compound (4) gave fully substituted mono-ferrocenyl-spiro-cyclotetraphosphazenes (4a-4d) with excess monoamines as well. The tetrameric phosphazene derivatives were characterized by ESI-MS and/or HRMS, FTIR, HSQC, HMBC, 1H, 13C, and 31P NMR spectroscopy and X-ray crystallog. (for 4). It is observed that the 2,4-ansa and spiro-cyclotetraphosphazenes have different thermal stabilities. Addnl., the CVs of the new mono-ferrocenyl pendant-armed cyclotetraphosphazenes revealed electrochem. reversible one-electron oxidation of the Fe-redox center. The 2,4-ansa phosphazenes (3 and 3a-3d) have two different stereogenic P centers indicating that they are expected to be in racemic mixtures (RR’/SS’). The chiralities of 3a and 3c were investigated by chiral HPLC. The manuscript also deals with the antimicrobial activities against G(+)/G(-) bacteria and fungi, the interactions with plasmid DNA, the in vitro cytotoxic activities against L929 fibroblast and MCF7 breast cells, and the antituberculosis activities against Mycobacterium tuberculosis H37Rv of the cyclotetraphosphazenes.

In 2022,Djeujo, Francine Medjiofack; Francesconi, Valeria; Gonella, Maddalena; Ragazzi, Eugenio; Tonelli, Michele; Froldi, Guglielmina published an article in Molecules. The title of the article was 《Anti-α-Glucosidase and Antiglycation Activities of α-Mangostin and New Xanthenone Derivatives: Enzymatic Kinetics and Mechanistic Insights through In Vitro Studies》.Reference of 3-Aminopropan-1-ol The author mentioned the following in the article:

Diabetes mellitus is characterized by chronic hyperglycemia that promotes ROS formation, causing severe oxidative stress. Furthermore, prolonged hyperglycemia leads to glycation reactions with formation of AGEs that contribute to a chronic inflammatory state. This research aims to evaluate the inhibitory activity of α-mangostin and four synthetic xanthenone derivatives against glycation and oxidative processes and on α-glucosidase, an intestinal hydrolase that catalyzes the cleavage of oligosaccharides into glucose mols., promoting the postprandial glycemic peak. Antiglycation activity was evaluated using the BSA assay, while antioxidant capacity was detected with the ORAC assay. The inhibition of α-glucosidase activity was studied with multispectroscopic methods along with inhibitory kinetic anal. α-Mangostin and synthetic compounds at 25 μM reduced the production of AGEs, whereas the α-glucosidase activity was inhibited only by the natural compound α-Mangostin decreased enzymic activity in a concentration-dependent manner in the micromolar range by a reversible mixed-type antagonism. CD revealed a rearrangement of the secondary structure of α-glucosidase with an increase in the contents of α-helix and random coils and a decrease in β-sheet and β-turn components. The data highlighted the anti-α-glucosidase activity of α-mangostin together with its protective effects on protein glycation and oxidation damage.3-Aminopropan-1-ol(cas: 156-87-6Reference of 3-Aminopropan-1-ol) was used in this study.

《3-Amino-1-propanol and N-methylaminoethanol: coordination to zinc(II) vs. decomposition to ammonia》 was written by Podjed, Nina; Stare, Petra; Korosec, Romana Cerc; Alcaide, Maria M.; Lopez-Serrano, Joaquin; Modec, Barbara. Related Products of 156-87-6This research focused onzinc quinaldinate aminopropanol methylaminoethanol ammonia complex preparation crystal structure; DFT calculation zinc quinaldinate aminopropanol methylaminoethanol ammonia complex. The article conveys some information:

To broaden the limited knowledge concerning the zinc(II) coordination chem. with amino alcs., reactions of [Zn(quin)2(H2O)] (quin- = quinaldinate, C10H6NO2) with 3-amino-1-propanol (3-apOH, C3H9NO) and N-methylaminoethanol (N-maeOH, C3H9NO) were studied. The starting material, zinc(II) with two quinaldinates coordinated in a bidentate chelating mode, provides a structurally rigid core with two sites available for interaction with amino alc. ligands. When the reactions were carried out in acetonitrile in autoclaves at 105°, an unforeseen decomposition of amino alcs. to ammonia took place. This was accompanied by crystallization of an ammine complex [Zn(quin)2(NH3)] (1). Mass spectrometry of the gaseous phases confirmed unambiguously the presence of ammonia in such reaction mixtures The desired complexes with coordinated amino alcs. could be obtained in good yield by carrying out the reactions at room temperature and/or in various solvents. Two novel amino alc. complexes were prepared, [Zn(quin)2(3-apOH)] and [Zn(quin)2(N-maeOH)]. The 3-apOH ligand was coordinated to zinc(II) in a monodentate manner via the amino nitrogen. The 3-apOH complex crystallizes as an acetonitrile (2a), ethanol (2b), 2-propanol (2c) or water (2d) solvate. The conversion of 2a to 2d was monitored by IR spectroscopy. In [Zn(quin)2(N-maeOH)] (3), the N-maeOH ligand was coordinated in a bidentate chelating manner through both functional groups. DFT calculations were performed on the isomers of [Zn(quin)2(3-apOH)] and [Zn(quin)2(N-maeOH)], which differ in the binding modes of their amino alc. ligands. Complete characterization of all compounds by x-ray structure anal., IR spectroscopy and NMR spectroscopy is presented. In the experiment, the researchers used many compounds, for example, 3-Aminopropan-1-ol(cas: 156-87-6Related Products of 156-87-6)

《Hypoxia-Responsive, Polymeric Nanocarriers for Targeted Drug Delivery to Estrogen Receptor-Positive Breast Cancer Cell Spheroids》 was written by Mamnoon, Babak; Feng, Li; Froberg, Jamie; Choi, Yongki; Sathish, Venkatachalem; Mallik, Sanku. Application In Synthesis of 3-Aminopropan-1-ol And the article was included in Molecular Pharmaceutics in 2020. The article conveys some information:

Uncontrolled cell growth, division, and lack of enough blood supply causes low oxygen content or hypoxia in cancerous tumor microenvironments. 17β-Estradiol (E2), an estrogen receptor (ER) ligand, can be incorporated on the surface of nanocarriers for targeted drug delivery to breast cancer cells overexpressing ER. In the present study, we synthesized estradiol-conjugated hypoxia-responsive polymeric nanoparticles (polymersomes) encapsulating the anticancer drug doxorubicin (E2-Dox-HRPs) for targeted delivery into the hypoxic niches of estrogen-receptor-pos. breast cancer microtumors. Estradiol-conjugated polymersomes released over 90% of their encapsulated Dox in a sustained manner within hypoxia (2% oxygen) after 12 h. However, they released about 30% of Dox in normal oxygen partial pressure (21% oxygen, normoxia) during this time. Fluorescence microscopic studies demonstrated higher cytosolic and nuclear internalization of E2-Dox-HRPs (targeted polymersomes) compared to those of Dox-HRPs (nontargeted polymersomes). Monolayer cell viability studies on ER-pos. MCF7 cells showed higher cytotoxicity of targeted polymersomes in hypoxia compared to in normoxia. Cytotoxicity studies with hypoxic three-dimensional spheroid cultures of MCF7 cells treated with targeted polymersomes indicated significant differences compared to those of normoxic spheroids. The novel estradiol-conjugated hypoxia-responsive polymersomes described here have the potential for targeted drug delivery in estrogen-receptor-pos. breast cancer therapy.

《Adaptive Se-Te Metathesis Controlled by Cucurbituril-Based Host-Guest Interaction》 was published in Chemistry – An Asian Journal in 2020. These research results belong to Liu, Cheng; Zhang, Zhiheng; Fan, Zhiyuan; He, Chaowei; Tan, Yizheng; Xu, Huaping. Electric Literature of C3H9NO The article mentions the following:

Regulating the reactivity and equilibrium of a dynamic reaction is essential for adaptive chem. and functional materials. Herein, cucurbituril-based host-guest interaction was embedded into the dynamic metathesis between diselenide and ditelluride to establish an equilibrium-adaptive system. In this system, cucurbit[6]uril (CB[6]) selectively bound with diselenide while cucurbit[7]uril (CB[7]) bound with not only diselenide but also ditelluride and exchange product. The dynamic nature of diselenide bond was locked after forming the inclusion complex with CB[6]. Based on this selective locking effect, the Se-Te products were reversed back to diselenide and ditelluride reactants, which was an equilibrium regulating process. Therefore, by combining CB[6]-based host-guest interaction and dynamic diselenide chem., the reactivity of diselenide bond and the equilibrium of Se-Te metathesis was successfully regulated. In the experiment, the researchers used 3-Aminopropan-1-ol(cas: 156-87-6Electric Literature of C3H9NO)

Golbedaghi, Reza; Justino, Licinia L. G.; Bahrampour, Marzyeh; Fausto, Rui published their research in Inorganica Chimica Acta in 2021. The article was titled 《A novel fluorescent chemosensor for Cu2+ ion based on a new hexadentate ligand receptor: X-ray single crystal of the perchlorate salt of the ligand, ion selectivity assays and TD-DFT study》.Electric Literature of C3H9NO The article contains the following contents:

New hexadentate chelates, H2L1 and L1, were synthesized. The Schiff base imine ligand, L1, was prepared by reaction of 2,2′-[ethane-1,2-diylbis(oxy)]dibenzaldehyde and propanolamine, and characterized by IR, 1H NMR and 13C NMR spectroscopies. The amine ligand, H2L1, was prepared as perchlorate salt ([H4L1](ClO4)2,) by reduction of L1 with NaBH4, and was characterized by IR (in KBr pellet), 1H NMR, 13C NMR and 2-dimensional NMR correlation spectroscopy (COSY) (in solution). The x-ray crystal structure of [H4L1](ClO4)2 was also determined and discussed. Fluorescence studies showed that H2L1 is a highly selective novel fluorescence chemosensor for the Cu2+ cation. The sensor shows selectivity for Cu2+ over 12 other metal cations. In presence of Cu2+ (5 equiv in the μM range) the fluorescence emission of the sensor, at 309 nm, is quenched by >98%. TD-DFT calculations show that ligand to metal charge transfer transitions in the complex formed between Cu2+ and the amine ligand contribute to the quenching of the fluorescence. An explanation based on TD-DFT results is also proposed for the weak fluorescence quenching in the presence of Zn2+.
