Free fatty acid receptor 2 (FFA2) is a G-protein coupled receptor for which only short-chain fatty acids (SCFAs) have been reported as endogenous ligands. We describe the discovery and optimization of phenylacetamides as allosteric agonists of FFA2. These novel ligands can suppress adipocyte lipolysis in vitro and reduce plasma FFA levels in vivo, suggesting that these allosteric modulators can serve as pharmacol. tools for exploring the potential function of FFA2 in various disease conditions. In addition to this study using 5-Bromothiazol-2-amine, there are many other studies that have used 5-Bromothiazol-2-amine(cas: 3034-22-8Reference of 5-Bromothiazol-2-amine) was used in this study.

5-Bromothiazol-2-amine(cas: 3034-22-8) belongs to anime. Left-handed and right-handed forms (mirror-image configurations, known as optical isomers or enantiomers) are possible when all the substituents on the central nitrogen atom are different (i.e., the nitrogen is chiral). With amines, there is extremely rapid inversion in which the two configurations are interconverted.Reference of 5-Bromothiazol-2-amine

The activity of a series of imidazo[2,1-b]thiazole guanidinylhydrazones as inhibitors of p90 ribosomal S6 kinase 2 (RSK2) is described. It was found that a small subset of compounds show both potent inhibition of RSK2 kinase activity and tumor cell growth in vitro. Detailed study of one of the most active compounds indicates a high degree of selectivity for inhibition of RSK2 compared to a spectrum of other related kinases. Selective inhibition of the MCF-7 breast tumor cell line compared to MCF-10A non-transformed cells, as well as selective inhibition of the biomarker GSK3 provides evidence that the compounds can affect the RSK2 target in cells.

Synthesis, characterization and evaluation of neuroprotective effects of a focused library of 4-imidazo[2,1-b]thiazole-1,4-dihydropyridines I [R = 2-FC6H4, 4-ClC6H4, 4-O2NC6H4, etc.; R1 = Me, Et, H2C=CHCH2; R2 = H, Me, Et, F, Cl, Br; R3 = H, Me]. Furthermore, the dihydropyridines were subjected to functional in vitro assays in cardiac tissues and vascular smooth muscle to determine their possible selectivity in counteracting the effects of neurodegeneration. In particular the strategy adopted for designing the compounds involved the imidazo[2,1-b]thiazole nucleus. The observed properties showed that substituents at C2 and C6 of the bicyclic scaffold were able to influence the cardiovascular parameters and the neuroprotective activity. In comparison to nifedipine, a set of derivatives such as compound I [R = CF3; R1 = Me; R2 = Me; R3 = H], showed a neuroprotective profile of particular interest.

The article was 《Graphene oxide-cytochrome C multilayered structures for biocatalytic applications: Role of surfactant in Langmuir-Schaefer layer deposition》. The article mentions the following:

Graphene, a two-dimensional single-layer carbon allotrope, has attracted tremendous scientific interest due to its outstanding physicochem. properties. Its monat. thickness, high sp. surface area, and chem. stability render it an ideal building block for the development of well-ordered layered nanostructures with tailored properties. Herein, biohybrid graphene-based layer-by-layer structures are prepared by means of conventional and surfactant-assisted Langmuir-Schaefer layer deposition techniques, whereby cytochrome C mols. are accommodated within ordered layers of graphene oxide. The biocatalytic activity of the as-developed nanobio-architectures toward the enzymic oxidation of 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt and decolorization of pinacyanol chloride is tested. The results show that the multilayer structures exhibit high biocatalytic activity and stability in the absence of surfactant mols. during the deposition of the monolayers.

Electric Literature of C7H5ClN2SOn October 1, 2019 ,《Discovery of novel pyrimidine-based benzothiazole derivatives as potent cyclin-dependent kinase 2 inhibitors with anticancer activity》 was published in European Journal of Medicinal Chemistry. The article was written by Diao, Peng-Cheng; Lin, Wei-Yuan; Jian, Xie-Er; Li, Yan-Hong; You, Wen-Wei; Zhao, Pei-Liang. The article contains the following contents:

To develop novel CDK2 inhibitors as anticancer agents, a series of novel pyrimidine-based benzothiazole derivatives I (R = 4-(S(O)2NH2), 4-(piperidin-1-yl), 3-F, etc.) and II (R1 = H, F, Cl, Me, MeO; R2 = H, Me, F; R3 = Me, NH2) was designed and synthesized. Initial biol. evaluation demonstrated that some of target compounds displayed potent antitumor activity in vitro against five cancer cell lines. Especially, the analog II (R1 = F; R2 = H; R3 = NH2) exhibited approx. potency with AZD5438 toward four cells including HeLa, HCT116, PC-3, and MDA-MB-231 with IC50 values of 0.45, 0.70, 0.92, 1.80 μM, resp. More interestingly, the most highly active compound II (R1 = F; R2 = H; R3 = NH2) in this study also possessed promising CDK2/cyclin A2 inhibitory activities with IC50 values of 15.4 nM, which was almost 3-fold potent than pos. control AZD5438, and mol. docking studies revealed that the analog bound efficiently with the CDK2 binding site. Further studies indicated that compound II (R1 = F; R2 = H; R3 = NH2) could induce cell cycle arrest and apoptosis in a concentration-dependent manner. These observations suggest that pyrimidine-benzothiazole hybrids represent a new class of CDK2 inhibitors and well worth further investigation aiming to generate potential anticancer agents.6-Chlorobenzothiazol-2-ylamine(cas: 95-24-9Electric Literature of C7H5ClN2S) was used in this study.

The continuing investigation of SAR studies of 3-(2-hydroxyethoxy)-N-(5-benzylthiazol-2-yl)benzamides as stearoyl-CoA desaturase-1 (SCD-1) inhibitors was reported. A prior hit-to-lead effort resulted in the identification of I (R = OMe) as a potent and orally efficacious SCD-1 inhibitor. Further optimization of the structural motif resulted in the identification of I (R = NHEt) with sub-nanomolar IC50 in both murine and human SCD-1 inhibitory assays. This compound demonstrated a dose-dependent decrease in the plasma desaturation index in C57BL/6J mice on a non-fat diet after 7 days of oral administration.

Ponatinib (AP24534) was previously identified as a pan-BCR-ABL inhibitor that potently inhibits the T315I gatekeeper mutant, and has advanced into clin. development for the treatment of refractory or resistant CML. In this study, we explored a novel series of five and six membered monocycles as alternate hinge-binding templates to replace the 6,5-fused imidazopyridazine core of ponatinib. Like ponatinib, these monocycles are tethered to pendant toluanilides via an ethynyl linker. Several compounds in this series displayed excellent in vitro potency against both native BCR-ABL and the T315I mutant. Notably, a subset of inhibitors exhibited desirable PK and were orally active in a mouse model of T315I-driven CML.
