Guidotti, Giulia; Soccio, Michelina; Gazzano, Massimo; Siracusa, Valentina; Lotti, Nadia published an article in 2021, the title of the article was Poly(Alkylene 2,5-Thiophenedicarboxylate) Polyesters: A New Class of Bio-Based High-Performance Polymers for Sustainable Packaging.Recommanded Product: 111-29-5 And the article contains the following content:

In the present study, 100% bio-based polyesters of 2,5-thiophenedicarboxylic acid were synthesized via two-stage melt polycondensation using glycols containing 3 to 6 methylene groups. The so-prepared samples were characterized from the mol. point of view and processed into free-standing thin films. Afterward, both the purified powders and the films were subjected to structural and thermal characterization. In the case of thin films, mech. response and barrier properties to O2 and CO2 were also evaluated. From the results obtained, it emerged that the length of glycolic sub-units is an effective tool to modulate the chain mobility and, in turn, the kind and amount of ordered phases developed in the samples. In addition to the usual amorphous and 3D crystalline phases, in all the samples investigated it was possible to evidence a further phase characterized by a lower degree of order (mesophase) than the crystalline one, whose amount is strictly related to the glycol sub-unit length. The relative fraction of all these phases is responsible for the different mech. and barrier performances. Last, but not least, a comparison between thiophene-based homopolymers and their furan-based homologues was carried out. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Recommanded Product: 111-29-5

Chung, Sheng-Hsuan; Lin, Ting-Ju; Hu, Qian-Yu; Tsai, Chia-Hua; Pan, Po-Shen published an article in 2013, the title of the article was Synthesis of boron-containing primary amines.Product Details of 1333264-06-4 And the article contains the following content:

B-containing primary amines were synthesized for use as building blocks in the study of peptoids. In the 1st step, Gabriel synthesis conditions were modified to enable the construction of seven different aminomethylphenyl boronate esters, e.g., p-(pinB)C6H4CH2NH2 (Bpin = 4,4,5,5-tetramethyl-1,3,2-dioxaborolanyl), in good to excellent yields. These compounds were further used to build peptoid analogs via an Ugi four-component reaction (Ugi-4CR) under microwave irradiation The prepared Ugi-4CR boronate esters were then successfully converted to the corresponding boronic acids. Finally, the peptoid structures were successfully modified by cross-coupling to aryl/heteroaryl chlorides via a Pd-mediated Suzuki coupling reaction to yield the corresponding derivatives in moderate to good yields. The experimental process involved the reaction of [4-Fluoro-3-(tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]methanol(cas: 1333264-06-4).Product Details of 1333264-06-4

Tsochatzis, Emmanouil; Lopes, Joao Alberto; Gika, Helen; Theodoridis, Georgios published an article in 2021, the title of the article was Polystyrene biodegradation by Tenebrio molitor larvae: identification of generated substances using a GC-MS untargeted screening method.SDS of cas: 96-76-4 And the article contains the following content:

A GC-MS method has been applied to screen and evaluate the generation of chem. compounds during the biodegradation of polystyrene (PS) with Tenebrio molitor larvae. Several resulting compounds have been identified, including trimers 2,4,6-triphenyl-1-hexene and 1,3,5-triphenylcyclohexane, the volatiles acetophenone and cumyl alc., and 2,4-di-tert butylphenol, a non-intentionally added substance (NIAS) present in the plastic material. The PS monomers styrene and a-Me styrene were also identified in the extracts Bioactive mols. present in the biomass of the studied insects were identified, such as the free fatty acids myristic, palmitic, and oleic acid. Undecanoic acid was also found, but in lower mass fractions. Finally, biochem. formatted amides resulting from their resp. fatty acids were identified, namely tetradecanamide, hexadecanamide and oleamide. The formation of all these substances seems to suggest enzymic and biochem. activity occurring during the biodegradation of PS, and their amounts varied throughout the experience. The overall degradation rate of PS resulted in a 13% rate, which highlights the potential of biorecycling using these insects. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).SDS of cas: 96-76-4

And the article contained the following:

Myxobacteria are micropredators in the soil ecosystem with the capacity to move and feed cooperatively. Some myxobacterial strains have been used to control soil-borne fungal phytopathogens. However, interactions among myxobacteria, plant pathogens, and the soil microbiome are largely unexplored. In this study, we aimed to investigate the behaviors of the myxobacterium Corallococcus sp. strain EGB in the soil and its effect on the soil microbiome after inoculation for controlling cucumber Fusarium wilt caused by Fusarium oxysporum f. sp. cucumerinum (FOC). A greenhouse and a 2-yr field experiment demonstrated that the solid-state fermented strain EGB significantly reduced the cucumber Fusarium wilt by 79.6% (greenhouse), 66.0% (2015, field), and 53.9% (2016, field). Strain EGB adapted to the soil environment well and decreased the abundance of soil-borne FOC efficiently. Spatiotemporal anal. of the soil microbial community showed that strain EGB migrated towards the roots and root exudates of the cucumber plants via chemotaxis. Cooccurrence network anal. of the soil microbiome indicated a decreased modularity and community number but an increased connection number per node after the application of strain EGB. Several predatory bacteria, such as Lysobacter, Microvirga, and Cupriavidus, appearing as hubs or indicators, showed intensive connections with other bacteria. The predatory myxobacterium Corallococcus sp. strain EGB controlled cucumber Fusarium wilt by migrating to the plant root and regulating the soil microbial community. This strain has the potential to be developed as a novel biol. control agent of soil-borne Fusarium wilt. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Related Products of 585-88-6

On December 11, 2008, Pinchuk, Anatoly; Weichert, Jamey P.; Longino, Marc published a patent.Recommanded Product: 2-Methyl-2-propylpropane-1,3-diol The title of the patent was Methods for the synthesis and use of phospholipid ether boronic acids and esters. And the patent contained the following:

The present invention discloses boronic acids and esters I [A = (CH2)n; X = boronic acid or ester; Y = NH2, NHR, NR2, NR+3; R = alkyl, arylalkly; n = 8 – 30], II [M = Li, Na, K, Cs, Rb] and III [Z = H, OH, OMe, OEt, OPr], of phospholipid ether (PLE) analogs and methods for their synthesis and use. A method of synthesizing a high specific activity PLE analog comprises: (a) coupling of a diboron with a PLE or alkyl phosphocholine (APC) analog in the presence of a catalyst to result in a boronic acid or ester PLE or APC analog; (b) optionally esterification the boronic acid of the PLE analog with 1,2- or 1,3-diols to result in the boronic esters of PLE or APC analogs; and, (c) optionally, reacting the boronic acid of ester of PLE or APC analog of (a) or (b) with sodium radiohalide, in the presence of an oxidant to result in a high specific activity radiohalogenated PLE or APC analog. Thus, NM404 (IV) was prepared from 4-IC6H4CH2Br via coupling with BrZn(CH2)11OAc, deacetylation with NaOH, Iodination with I2/PPH3/imidazole, coupling with BrZn(CH2)5CO2Et, saponification with NaOH, reduction with BH3·THF, phosphorylation with ethylene chlorophosphate, and reaction with NMe3. Coupling reaction of IV with bis(neopentylglycolato)diboron in MeOH containing KOAc and catalytic PdCl2(DPPF) gave II [X = B(OH)2], while coupling with bis(pinacolato)diboron gave II [X = pinacolborane]. Reaction of II [X = B(OH)2] with Na125I in aqueous NaOH containing chloramine-T gave 125I-NM404. The boronic acids and esters of phospholipid ether analogs described herein can be used in treating cancer and in particular can be used in conjunction with radiation therapy, such as external beam radiation therapy and neutron capture therapy to specifically target and kill cancer cells [see graphs]. The experimental process involved the reaction of 2-Methyl-2-propylpropane-1,3-diol(cas: 78-26-2).Recommanded Product: 2-Methyl-2-propylpropane-1,3-diol

Zhao, Fuqiang; Wang, Ping; Lucardi, Rima D.; Su, Zushang; Li, Shiyou published an article in 2020, the title of the article was Natural sources and bioactivities of 2,4-Di-tert-butylphenol and its analogs.Safety of 2,4-Di-tert-butylphenol And the article contains the following content:

2,4-Di-tert-butylphenol or 2,4-bis(1,1-dimethylethyl)-phenol (2,4-DTBP) is a common toxic secondary metabolite produced by various groups of organisms. The biosources and bioactivities of 2,4-DTBP have been well investigated, but the phenol has not been systematically reviewed. This article provides a comprehensive review of 2,4-DTBP and its analogs with emphasis on natural sources and bioactivities. 2,4-DTBP has been found in at least 169 species of bacteria (16 species, 10 families), fungi (11 species, eight families), diatom (one species, one family), liverwort (one species, one family), pteridiphyta (two species, two families), gymnosperms (four species, one family), dicots (107 species, 58 families), monocots (22 species, eight families), and animals (five species, five families). 2,4-DTBP is often a major component of violate or essential oils and it exhibits potent toxicity against almost all testing organisms, including the producers; however, it is not clear why organisms produce autotoxic 2,4-DTBP and its analogs. The accumulating evidence indicates that the endocidal regulation seems to be the primary function of the phenols in the producing organisms. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Safety of 2,4-Di-tert-butylphenol

Humboldtia unijuga Bedd., endemic to Agasthyamala in Western Ghats in India, is traditionally used by local Kani tribes for chicken pox, head ache and snake bite. This study reports the isolation of erythrodiol-3-acetate (HU-1) and 2,4-di-tert-butylphenol (HU-2) from H. unijuga roots and their anti-inflammatory and anticancer activities in macrophage, skin and breast cancer cell lines. Effects of HU-1 and HU-2 treatments (50, 100μg/mL) on gene expression profiles of pro-inflammatory cytokines TNFα, IL-6 and IL-1β, and apoptosis genes p53 and caspase 7 were studied. HU-2 exerted a significantly superior anti-inflammatory effect compared to HU-1 in all three pro-inflammatory genes. HU-2 showed a superior dose dependent anticancer effect through activation of p53 gene over HU-1 in MCF-7 cells. HU-1 exhibited a dose dependent effect on caspase 7 gene in both cell lines while HU-2 was more effective in A431. HU-2 has potential for development as a novel anti-inflammatory and anticancer agent. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Formula: C14H22O
