And the article contained the following:

In positron emission tomog. [11C]PIB, Pittsburgh Compound-B, is currently the most widely used radiopharmaceutical for the early diagnosis of Alzheimer’s disease. Synthetic routes for the preparation of the precursor of [11C]PIB are reported in the literature. These strategies require multiple steps and the use of protecting groups. This paper describes a simple 1-step synthesis of the precursor of [11C]PIB through a Suzuki-Miyaura coupling reaction using thermal conditions or microwave activation. These methods were successfully applied to the synthesis of various 2-arylbenzothiazole and 2-pyridinylbenzothiazole compounds including [18F] precursor derivatives of PIB containing a nitro function. The experimental process involved the reaction of 2-(4-Aminophenyl)-6-methylbenzothiazole(cas: 92-36-4).Recommanded Product: 2-(4-Aminophenyl)-6-methylbenzothiazole

On February 28, 2022, Cai, Mingzhong; Ye, Qian; Huang, Wencheng; Hao, Wenyan published an article.SDS of cas: 92-36-4 The title of the article was Recyclable copper-catalyzed cyclization of o-haloanilides and metal sulfides: An efficient and practical access to substituted benzothiazoles. And the article contained the following:

An efficient heterogeneous copper-catalyzed cyclization of o-haloanilides and metal sulfides has been achieved via the C-S coupling in DMF at 80 or 140° in the existence of an MCM-41-bound NHC-Cu(I) catalyst and then intramol. condensation, delivering a wide range of substituted benzothiazoles in mostly good to high yields. This new MCM-41-NHC-CuI complex can facilely be obtained by a two-step procedure starting from easily accessible and inexpensive reagents and reused more than seven times without any significant loss of its catalytic efficiency. The present protocol has been successfully applied to the gram-scale synthesis of two antitumor agents 5F203 and PMX 610. The experimental process involved the reaction of 2-(4-Aminophenyl)-6-methylbenzothiazole(cas: 92-36-4).SDS of cas: 92-36-4

On February 13, 2003, Wells, Geoffrey; Berry, Jane M.; Bradshaw, Tracey D.; Burger, Angelika M.; Seaton, Angela; Wang, Bo; Westwell, Andrew D.; Stevens, Malcolm F. G. published an article.Application of 92-36-4 The title of the article was 4-Substituted 4-Hydroxycyclohexa-2,5-dien-1-ones with Selective Activities against Colon and Renal Cancer Cell Lines. And the article contained the following:

The synthesis and antitumor evaluation of a series of new heteroaromatic- and aromatic-substituted hydroxycyclohexadienones (quinols), and their imine counterparts, are described. The quinols were synthesized via the addition of a lithiated aromatic moiety to a quinone ketal followed by deprotection. When the aromatic portion of the mol. is a fused heterobicyclic structure (e.g., benzothiazole derivative I), potent in vitro antitumor activity was observed in HCT 116 (GI50 = 40 nM) and HT 29 (GI50 = 380 nM) human colon as well in as MCF-7 and MDA 468 human breast cancer cell lines. When examined on the NCI Developmental Therapeutics Screening Program in vitro screen (60 human cancer cell lines), active compounds in this series consistently displayed a highly unusual pattern of selectivity; cytotoxicity (LC50) was concentrated in certain colon and renal cell lines only. I also showed in vivo antitumor activity against human RXF 944XL renal xenografts in nude NMRI mice and is the focus of further study. The experimental process involved the reaction of 2-(4-Aminophenyl)-6-methylbenzothiazole(cas: 92-36-4).Application of 92-36-4

V.; Pedemonte, Nicoletta; Fossa, Paola; Millo, Enrico published an article.Application In Synthesis of 2-Amino-4-(4-iodophenyl)thiazole The title of the article was Synthesis and biological evaluation of novel thiazole- VX-809 hybrid derivatives as F508del correctors by QSAR-based filtering tools. And the article contained the following:

The most common CF mutation, F508del, impairs the processing and gating of CFTR protein. This deletion results in the improper folding of the protein and its degradation before it reaches the plasma membrane of epithelial cells. Present correctors, like VX809 only induce a partial rescue of the mutant protein. Our previous studies reported a class of compounds, called aminoarylthiazoles (AATs), featuring an interesting activity as correctors. Some of them show additive effect with VX-809 (I) indicating a different mechanism of action. In an attempt to construct more interesting mols., it was thought to generate chem. hybrid compounds, blending a portion of VX-809 merged to the thiazole scaffold. This approach was guided by the development of QSAR analyses, which were performed based on the F508del correctors so far disclosed in the literature. This strategy was aimed at exploring the key requirements turning in the corrector ability of the collected derivatives and allowed us to derive a predictive model guiding for the synthesis of novel hybrids as promising correctors. The new mols. were tested in functional and biochem. assays on bronchial CFBE41o-cells expressing F508del-CFTR showing a promising corrector activity. The experimental process involved the reaction of 2-Amino-4-(4-iodophenyl)thiazole(cas: 31699-14-6).Application In Synthesis of 2-Amino-4-(4-iodophenyl)thiazole

On January 8, 2009, Wang, Xueqing; Sarris, Katerina; Kage, Karen; Zhang, Di; Brown, Scott P.; Kolasa, Teodozyi; Surowy, Carol; El Kouhen, Odile F.; Muchmore, Steven W.; Brioni, Jorge D.; Stewart, Andrew O. published an article.Formula: C14H12N2S The title of the article was Synthesis and Evaluation of Benzothiazole-Based Analogues as Novel, Potent, and Selective Fatty Acid Amide Hydrolase Inhibitors. And the article contained the following:

High-throughput screening (HTS) identified benzothiazole analog (I) as a potent fatty acid amide hydrolase (FAAH) inhibitor. Structure-activity relationship (SAR) studies indicated that the sulfonyl group, the piperidine ring and benzothiazole were the key components to their activity, with II being the most potent analog in this series. Time-dependent preincubation study of compound I was consistent with it being a reversible inhibitor. Activity-based protein-profiling (ABPP) evaluation of I in rat tissues revealed that it had exceptional selectivity and no off-target activity with respect to other serine hydrolases. Mol. shape overlay of I with a known FAAH inhibitor indicated that these compounds might act as transition-state analogs, forming putative hydrogen bonds with catalytic residues and mimicking the charge distribution of the tetrahedral transition state. The modeling study also indicated that hydrophobic interactions of the benzothiazole ring with the enzyme contributed to its extraordinary potency. These compounds may provide useful tools for the study of FAAH and the endocannabinoid system. The experimental process involved the reaction of 2-(4-Aminophenyl)-6-methylbenzothiazole(cas: 92-36-4).Formula: C14H12N2S

On April 29, 2020, Poisson, Luigi; Pittet, Jonathan; Schaerer, Anja; Mestdagh, Frederic; Davidek, Tomas published an article.Product Details of 24295-03-2 The title of the article was Quantitative Validation of the In-Bean Approach in Coffee Roasting. And the article contained the following:

The representativeness of the so-called biomimetic “in-bean” technique was studied by following the formation of target aroma compounds during the roasting course (10 points from 0 to 400 s) in recombined coffee beans and non-treated green coffee reference beans. For this purpose, the water-soluble fraction was replaced by a biomimetic recombinate in reconstituted beans prior to roasting. The targeted anal. of key aroma compounds was performed by means of the stable isotope dilution assay and solid-phase microextraction-gas chromatog.-mass spectrometry of roasted and ground coffee samples. The results were compared to the quant. data on a green coffee reference roasted under the same conditions. The results showed similar formation kinetics for most of the evaluated volatiles, such as Strecker aldehydes, alkylpyrazines, or α-diketones. In addition, the final quantities of key odorants in both types of samples were quite comparable. Hence, the refined biomimetic approach was validated as a valuable tool in studying different aspects of flavor formation upon coffee roasting. The experimental process involved the reaction of 2-Acetylthiazole(cas: 24295-03-2).Product Details of 24295-03-2
