Paragraph 0174; 0175; 0176; 0177, (2017/08/31)
The invention belongs to the field of medicinal chemicals, relates to a STAT3 inhibitor, and in particular to a (S)-N-(1-phenethyl) thioacetamide compound of a structure of formula (I) as shown in the specification, a medicinal composition of the compound as an STAT3 (Signal Transducer and Activator of Transcription 3) signal path inhibitor, and application of the compound in preparing anti-tumor medicines. Results of cell experiment show that the compound targets a Phe-Lys-Thr-Lys-Leu pentapeptide binding region in an STAT3 SH2 structure domain, then inhibits STAT3 protein monomer dimerization and silencing STAT3 signal transduction and functions, has a remarkable anti-tumor effect and good physical and chemical properties, is particularly capable of effectively preventing cell proliferative activity in breast cancer cells with high expression of STAT3 and HEL cells on which JAK2/STAT3 signal paths depend with JAK2 V671F mutation, and moreover is capable of effectively inhibiting phosphorylation of STAT3 in the breast cancer cells with high expression of STAT3 and expression of downstream target genes such as CyclinD1 and Bc1-2.

Objective: The objective of the present research investigation involves synthesis and biological evaluation of antidiabetic activity of benzothiazole derivatives. Methods: A novel series of benzothiazole derivatives 7(a-l) were synthesised and synthesised compounds were characterised for different physical and chemical properties like molecular formula, molecular weight, melting point, percentage yield, Rf value, IR,1HNMR,13CNMR and mass spectroscopy. The newly synthesised benzothiazole derivatives were subsequently assayed in vivo to investigate their hypoglycemic activity by the alloxan-induced diabetic model in rats. Results: All the synthesised derivatives showed significant biological efficacy. The compound 7d at 350 mg/kg exerted maximum glucose lowering effects whereas 7c showed minimum glucose lowering effects. All the compounds were effective, and experimental results were statistically significant at p0.01 and p0.05 level. Conclusion: From the results, it is clear that compound 7d demonstrated potent anti-diabetic activity and would be of better use in drug development to combat the metabolic disorder in future.

Alpha-dystroglycan (α-DG), a highly glycosylated receptor for extracellular matrix proteins, plays a critical role in many biological processes. Hypoglycosylation of α-DG results in various types of muscular dystrophies and is also highly associated with progression of majority of cancers. Currently, there are no effective treatments for those devastating diseases. Enhancing functional O-mannosyl glycans (FOG) of α-DG on the cell surfaces is a potential approach to address this unmet challenge. Based on the hypothesis that the cells can up-regulate FOG of α-DG in response to certain chemical stimuli, we developed a cell-based high-throughput screening (HTS) platform for searching chemical enhancers of FOG of α-DG from a large chemical library with 364,168 compounds. Sequential validation of the hits from a primary screening campaign and chemical works led to identification of a cluster of compounds that positively modulate FOG of α-DG on various cell surfaces including patient-derived myoblasts. These compounds enhance FOG of α-DG by almost ten folds, which provide us powerful tools for O-mannosylation studies and potential starting points for the development of drug to treat dystroglycanopathy.

, p. 727 - 730 (2007/10/03)
A convenient synthesis of 2-mercapto and 2-chlorobenzothiazoles is described. The key feature of the synthesis is an exclusive ortho-selective nucleophilic aromatic substitution reaction of ortho-haloanilines with potassium/sodium O-ethyl dithiocarbonate under mild conditions. Subsequent intra-molecular cyclization affords 2-mercaptobenzothiazoles in high yields. The 2-mercaptobenzothiazoles are readily converted to corresponding 2-chlorobenzothiazoles upon treatment with sulfuryl chloride.
