Uniform nanopowders of barium aluminate (BaAl2O4) can be synthesized by a facile solution reaction at room temperature using barium and aluminum salts and 2-aminoethanol as a precipitating agent. The asprepared sample showed a good reactivity in the synthesis of benzo[b]thiophene, thieno[2,3-c]thiopyran and thieno[2,3-c]pyridine derivatives. Comparatively the method is efficient and eco-friendly, and finally, a range of compounds with variable functionalities in excellent yield can be achieved.

Transmembrane protein 16A (TMEM16A), also called anoctamin 1 (ANO1), is a calcium-activated chloride channel expressed widely mammalian cells, including epithelia, vascular smooth muscle tissue, electrically excitable cells, and some tumors. TMEM16A inhibitors have been proposed for treatment of disorders of epithelial fluid and mucus secretion, hypertension, asthma, and possibly cancer. Herein we report, by screening, the discovery of 2-acylaminocycloalkylthiophene-3-carboxylic acid arylamides (AACTs) as inhibitors of TMEM16A and analysis of 48 synthesized analogs (10ab-10bw) of the original AACT compound (10aa). Structure-activity studies indicated the importance of benzene substituted as 2- or 4-methyl, or 4-fluoro, and defined the significance of thiophene substituents and size of the cycloalkylthiophene core. The most potent compound (10bm), which contains an unusual bromodifluoroacetamide at the thiophene 2-position, had IC50 of ~30 nM, ~3.6-fold more potent than the most potent previously reported TMEM16A inhibitor 4 (Ani9), and >10-fold improved metabolic stability. Direct and reversible inhibition of TMEM16A by 10bm was demonstrated by patch-clamp analysis. AACTs may be useful as pharmacological tools to study TMEM16A function and as potential drug development candidates.

TETRAHYDROBENZO[B]THIOPHENE derivatives 3a,b and 5a,b were synthesized followed by the alkylation of some derivatives. The antitumor evaluation of the newly synthesized products against three cancer cell lines, namely breast adenocarcinoma (MCF-7), non-small cell lung cancer (NCI-H460) and CNS cancer (SF-268) was recorded. Some of the synthesized compounds show high inhibitory effects.

Under microwave irradiation and solvent-free conditions, cyanoacetates (cyanoacetamides) react with ketones and sulphur in the presence of a small amount of morpholine to give 2-amino-thiophene-3-carboxylic derivatives. In particular, tetrahydro-benzo[b]thiophene-3-carboxylic acid N-aryl amides were synthesized in high yields of 84-95%. Copyright Taylor & Francis, Inc.

Twenty new 2-substituted aminoacetylamino-3-carbetoxy/anilido-4,5,6,7-tetrahydrobenzothiophenes (4a-4t) have been synthesised with a view to studying the effect of structural modification of carticaine (B) on the local anaesthetic activity and evaluated by Sollman's method as well as Bulbring and Wajda method using lignocaine hydrochloride as a standard.All the tested compounds show moderate to good activity and 4a has been found to be the most active drug comparable to the standard.
