Environmentally benign and biodegradable lactic acid was identified as alternative solvent and catalyst for the tandem one-pot synthesis of Hantzsch 2-aminothiazole derivatives from readily available aralkyl ketones through in-situ regioselective α-bromination using N-bromosuccinimide followed by heterocyclization using thiourea at 90-100°. The major advantages of the present method include short reaction times (10-15 min), practical, simple to perform, easy work-up, good yield of products (up to 96%), productive for large-scale applications, free from apply of α-bromoketones (lachrymator) as substrates, avoids column purification Hence, the present method met with the concepts of both Wender’s “”ideal synthesis”” and sustainable chem. process.

Treatment of N-(2,2,2-trichloro-1-tosylethyl)dichloroacetamide with excess Me2NH, piperidine, or morpholine gave substituted aminals of the oxazole series, whose facile acid hydrolysis provided 5-(dimethylamino)-4-tosyl-1,3-oxazole-2-carbaldehyde and its analogs having the piperidino and morpholino group in the 5-position of the oxazole ring. The resulting aldehydes and their aminals were condensed with PhN2H3, thiosemicarbazide, N-alkylrhodanines, and 1,3-dimethylbarbituric acid to obtain 2,5-disubstituted 4-tosyl-1,3-oxazoles.

Li, Rifei; Zhu, Xinjie; Zhou, Peng; Qiao, Yuehua; Li, Yinqian; Xu, Yice; Shi, Xi published the artcile< Generation of a high-affinity nanobody against CD147 for tumor targeting and therapeutic efficacy through conjugating doxorubicin>, Category: thiazole, the main research area is CD147 tumor targeting conjugating doxorubicin anticancer agent breast cancer; CD147; DOX–11-1; nanobody; phage display; tumor targeting.

CD147, a glycosylated transmembrane protein in the Ig superfamily, is overexpressed on the surfaces of various tumor cells and promotes cancer cell proliferation, invasion, and metastasis. Nanobodies, characterized by small sizes, high affinities and specificities, and low immunogenicities, are promising diagnostic and therapeutic tools. However, there are few reports on nanobodies that specifically target CD147. In this work, a specific anti-CD147 nanobody has been successfully identified using phage display technol. The tumor target and antitumor effects have also been detected in different CD147-pos. tumors in in vitro and in vivo assays, resp. Meanwhile, it has a synergistic effect for inhibiting 4T1-bearing mice through conjugating doxorubicin. It may afford new strategies for cancer therapies.

Optimization of a high-throughput screening hit led to the discovery of a new series of 5-phenoxy-1,3-dimethyl-1H-pyrazole-4-carboxamides as highly potent agonists of TGR5. This novel chemotype was rapidly developed through iterative combinatorial library synthesis. It was determined that in vitro agonist potency correlated with functional activity data from human peripheral blood monocytes.

Kanou, Harumi; Nagasawa, Kouki; Ishii, Yuki; Chishima, Aya; Hayashi, Juri; Haga, Sanae; Sutherland, Kenneth; Ishikawa, Masayori; Ozaki, Michitaka; Shirato, Hiroki; Hamada, Kazuko; Hamada, Toshiyuki published the artcile< Period1 gene expression in the olfactory bulb and liver of freely moving streptozotocin-treated diabetic mouse>, Recommanded Product: (S)-2-(6-Hydroxybenzo[d]thiazol-2-yl)-4,5-dihydrothiazole-4-carboxylic acid, the main research area is period1 gene expression olfactory bulb liver diabetes mellitus; Circadian rhythm; In vivo imaging; Luciferin; Period1.

Clock genes express circadian rhythms in most organs. These rhythms are organized throughout the whole body, regulated by the suprachiasmatic nucleus (SCN) in the brain. Disturbance of these clock gene expression rhythms is a risk factor for diseases such as obesity. In the present study, to explore the role of clock genes in developing diabetes, we examined the effect of streptozotocin (STZ)-induced high glucose on Period1 (Per1) gene expression rhythm in the liver and the olfactory bub (OB) in the brain. We found a drastic increase of Per1 expression in both tissues after STZ injection while blood glucose content was low. After a rapid expression peak, Per1 expression showed no rhythm. Associated with an increase of glucose content, behavior became arrhythmic. Finally, we succeeded in detecting an increase of Per1 expression in mice hair follicles on day 1 after STZ administration, before the onset of symptoms. These results show that elevated Per1 expression by STZ plays an important role in the aggravation of diabetes.
