R.; Ellaby, Rebecca J.; Williams, George T.; Mulvihill, Daniel P.; Hiscock, Jennifer R. published an article in 2020, the title of the article was Controllable hydrogen bonded self-association for the formation of multifunctional antimicrobial materials.Recommanded Product: 92-36-4 And the article contains the following content:

SSAs are a class of supramol. self-associating amphiphilic salt, the anionic component of which contains a covalently bound hydrogen bond donor-acceptor motif. This results in a monomeric unit which can adopt multiple hydrogen bonding modes simultaneously. Previous investigations have shown examples of SSAs to act as antimicrobial agents against clin. relevant methicillin-resistant Staphylococcus aureus (MRSA). Herein, we report an intrinsically fluorescent SSA which can self-associate producing dimers, spherical aggregates and hydrogels dependent on solvent environment, while retaining antimicrobial activity against both model Gram-pos. (MRSA) and Gram-neg. (Escherichia coli) bacteria. Finally, we demonstrate the SSA supramol. hydrogel to tolerate the inclusion of the antibiotic ampicillin, leading to the enhanced inhibition of growth with both model bacteria, and derive initial mol. structure-physicochem. property-antimicrobial activity relationships. The experimental process involved the reaction of 2-(4-Aminophenyl)-6-methylbenzothiazole(cas: 92-36-4).Recommanded Product: 92-36-4

And the article contained the following:

This study aimed to identify the characteristic aroma compounds of beef soup and analyze the differences between their aroma. Seven beef soup samples were analyzed by sensory evaluation combined with gas chromatog.-mass spectrometry (GC-MS) and electronic nose (E-nose). A total of 80 volatile compounds were identified, and seven key aroma compounds in beef soup samples were determined by odor activity value, sensory evaluation, aroma recombination and omission experiments They were linalool, (E)-3,7-dimethyl-2,6-octadien-1-ol, nonanal, (E)-2-octenal, 3,7-dimethyl-2,6-octadienal, 2-acetylthiazole and estragole. The panelists described the organoleptic characteristics of beef soup as beef meaty, spice, fatty, caramel, and roasted. GC-MS and E-nose combined with principal component anal. showed different aroma profiles among beef soup samples. A total of 30 potential differential markers were screened by partial least squares discriminant anal. The difference between samples was mainly caused by the type and content of compounds The experimental process involved the reaction of 2-Acetylthiazole(cas: 24295-03-2).Product Details of 24295-03-2

On March 31, 2022, Li, Xinzhi; Liu, Shao-Quan published an article.SDS of cas: 24295-03-2 The title of the article was Modulation of aroma compounds in yeast and lactic acid bacterium co-fermented pork hydrolysates by thermal treatment and addition of aroma precursors (cysteine and xylose). And the article contained the following:

The objective of this study was to evaluate the effectiveness of using enzymic hydrolysis and microbial fermentation coupled with thermal treatment methods in valorising a type of industrially generated meat byproduct: pork trimmings, so as to produce a value-added meat-based flavouring. The pork trimmings were first hydrolyzed using a protease (Flavourzyme) under optimized conditions and then fermented into liquid hydrolyzates with mixed Lactobacillus fermentum and Pichia kluyveri; afterwards, xylose and cysteine were added to the fermented hydrolyzates for heat treatment. A characteristic “savoury and roasted-meat” aroma was produced due to the formation of potent sulfur-containing volatile compounds such as 2-furfurylthiol and methionol, though the browning intensity was inhibited due to the presence of cysteine. The thermal treatment did not significantly affect the fruity and sweet-smelling ester volatiles such as isoamyl acetate and hexyl acetate that resulted from microbial fermentation The decreases of amino acids and xylose might be due to their active participation in the Maillard reaction. The produced pork hydrolyzates that imparted a unique aroma could be applied as a flavor enhancer or seasoning in the food industry. The experimental process involved the reaction of 2-Acetylthiazole(cas: 24295-03-2).SDS of cas: 24295-03-2

And the article contained the following:

G-quadruplex has attracted considerable attention due to their prevalent distribution in functional genomic regions and transcripts, which can importantly influence biol. processes such as regulation of telomere maintenance, gene transcription and gene translation. Artificial receptor study has been developed for accurate identification of G-quadruplex from DNA species, since it is important for the G-quadruplex related basic research, clin. diagnosis, and therapy. Herein, fluorescent dye ThT-E, a derivative of the known fluorescence probe Thioflavin T (ThT), was designed and synthesized to effectively differentiate various G-quadruplex structures from other nucleic acid forms. Compared with Me groups in ThT, three Et groups were introduced to ThT-E, which leads to strengthened affinity, selectivity and little inducing effect on the G-quadruplex formation. More importantly, ThT-E could be served as a visual tool to directly differentiate G-quadruplex solution even with naked eyes under illumination of UV light. Thus, this probe reported herein may hold great promise for high-throughput assay to screen G-quadruplex, which may widely apply to G-quadruplex-based potential diagnosis and therapy. The experimental process involved the reaction of 2-(4-Aminophenyl)-6-methylbenzothiazole(cas: 92-36-4).Application of 92-36-4

On February 23, 2005, Solbach, C.; Uebele, M.; Reischl, G.; Machulla, H.-J. published an article.Quality Control of 2-(4-Aminophenyl)-6-methylbenzothiazole The title of the article was Efficient radiosynthesis of carbon-11 labelled uncharged Thioflavin T derivatives using [11C]methyl triflate for β-amyloid imaging in Alzheimer’s Disease with PET. And the article contained the following:

The synthesis of carbon-11 amino function labeled uncharged Thioflavin T derivatives is known to be performed by reaction of the demethyl-precursors with [11C]methyl iodide but the labeling yields are only mediocre. The use of [11C]methyl triflate improved the radiochem. yield of three potential β-amyloid imaging PET-radiotracers significantly. Performance of the labeling reaction by reacting the corresponding precursor mols. with [11C]methyl triflate for 1 min at 80° led to radiochem. yields of 44±10% (n = 5) for [11C]6-Me-BTA-1, 68±4% (n = 10) for [11C]BTA-1 and 58±2% (n = 5) for [11C]6-OH-BTA-1 with respect to [11C]methyl triflate. In production runs (60 min, 50 μA) up to 6500 MBq (mean: 4000±1900 MBq) of [11C]6-Me-BTA-1, 7900 MBq (mean: 6000±1000 MBq) of [11C]BTA-1 and 7100 MBq (mean: 6300±600 MBq) of [11C]6-OH-BTA-1 could be obtained ready for i.v. injection. The radiochem. purity was >95% with specific activities in the range of 80-120 GBq/μmol (EOS) within a total synthesis time of less than 40 min after EOB. The experimental process involved the reaction of 2-(4-Aminophenyl)-6-methylbenzothiazole(cas: 92-36-4).Quality Control of 2-(4-Aminophenyl)-6-methylbenzothiazole

Du, Zhi; Yu, Dongqin; Du, Xiubo; Scott, Peter; Ren, Jinsong; Qu, Xiaogang published an article in 2019, the title of the article was Self-triggered click reaction in an Alzheimer’s disease model: in situ bifunctional drug synthesis catalyzed by neurotoxic copper accumulated in amyloid-beta plaques.COA of Formula: C14H12N2S And the article contains the following content:

Cu is one of the essential elements for life. Its dyshomeostasis has been demonstrated to be closely related to neurodegenerative disorders, such as Alzheimer’s disease (AD), which is characterized by amyloid-beta (Abeta) aggregation and Cu accumulation. It is a great challenge as to how to take advantage of neurotoxic Cu to fight disease and make it helpful. Herein, we report that the accumulated Cu in Abeta plaques can effectively catalyze an azide-alkyne bioorthogonal cycloaddition reaction for fluorophore activation and drug synthesis in living cells, a transgenic AD model of Caenorhabditis elegans CL2006, and brain slices of triple transgenic AD mice. More importantly, the in situ synthesized bifunctional drug 6 can disassemble Abeta-Cu aggregates by extracting Cu and photo-oxygenating Abeta synergistically, suppressing Abeta-mediated paralysis and diminishing the locomotion defects of the AD model CL2006 strain. Our results demonstrate that taking the accumulated Cu ions in the Abeta plaque for an in situ click reaction can achieve both a self-triggered and self-regulated drug synthesis for AD therapy. To the best of our knowledge, a click reaction catalyzed by local Cu in a physiol. environment has not been reported. This work may open up a new avenue for in situ multifunctional drug synthesis by using endogenous neurotoxic metal ions for the treatment of neurodegenerative diseases.

On May 21, 2008, Brak, Katrien; Doyle, Patricia S.; McKerrow, James H.; Ellman, Jonathan A. published an article.COA of Formula: C8H7NOS The title of the article was Identification of a New Class of Nonpeptidic Inhibitors of Cruzain. And the article contained the following:

Cruzain is the major cysteine protease of Trypanosoma cruzi, which is the causative agent of Chagas disease and is a promising target for the development of new chemotherapy. With the goal of developing potent nonpeptidic inhibitors of cruzain, the substrate activity screening (SAS) method was used to screen a library of protease substrates initially designed to target the homologous human protease cathepsin S. Structure-based design was next used to further improve substrate cleavage efficiency by introducing addnl. binding interactions in the S3 pocket of cruzain. The optimized substrates were then converted to inhibitors by the introduction of cysteine protease mechanism-based pharmacophores. Inhibitor 38 was determined to be reversible even though it incorporated the vinyl sulfone pharmacophore that is well documented to give irreversible cruzain inhibition for peptidic inhibitors. The previously unexplored β-chloro vinyl sulfone pharmacophore provided mechanistic insight that led to the development of potent irreversible acyl- and aryl-oxymethyl ketone cruzain inhibitors. For these inhibitors, potency did not solely depend on leaving group pKa, with 2,3,5,6-tetrafluorophenoxymethyl ketone 54 identified as one of the most potent inhibitors with a second-order inactivation constant of 147,000 s-1 M-1. This inhibitor completely eradicated the T. cruzi parasite from mammalian cell cultures and consequently has the potential to lead to new chemotherapeutics for Chagas disease. The experimental process involved the reaction of Benzo[d]thiazol-6-ylmethanol(cas: 19989-66-3).COA of Formula: C8H7NOS

On January 18, 2012, Capule, Christina C.; Brown, Caitlin; Olsen, Joanna S.; Dewhurst, Stephen; Yang, Jerry published an article.Name: 2-(4-Aminophenyl)-6-methylbenzothiazole The title of the article was Oligovalent Amyloid-Binding Agents Reduce SEVI-Mediated Enhancement of HIV-1 Infection. And the article contained the following:

This paper evaluates the use of oligovalent amyloid-binding mols. as potential agents that can reduce the enhancement of human immunodeficiency virus-1 (HIV-1) infection in cells by semen-derived enhancer of virus infection (SEVI) fibrils. These naturally occurring amyloid fibrils found in semen have been implicated as mediators that can facilitate the attachment and internalization of HIV-1 virions to immune cells. Mols. that are capable of reducing the role of SEVI in HIV-1 infection may, therefore, represent a novel strategy to reduce the rate of sexual transmission of HIV-1 in humans. Here, we evaluated a set of synthetic, oligovalent derivatives of benzothiazole aniline (BTA, a known amyloid-binding mol.) for their capability to bind cooperatively to aggregated amyloid peptides and to neutralize the effects of SEVI in HIV-1 infection. We demonstrate that these BTA derivatives exhibit a general trend of increased binding to aggregated amyloids as a function of increasing valence number of the oligomer. Importantly, we find that oligomers of BTA show improved capability to reduce SEVI-mediated infection of HIV-1 in cells compared to a BTA monomer, with the pentamer exhibiting a 65-fold improvement in efficacy compared to a previously reported monomeric BTA derivative These results, thus, support the use of amyloid-targeting mols. as potential supplements for microbicides to curb the spread of HIV-1 through sexual contact.
