  Substituted 2-Acylaminocycloalkylthiophene-3-carboxylic Acid Arylamides as Inhibitors of the Calcium-Activated Chloride Channel Transmembrane Protein 16A (TMEM16A)

  摘要：

  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 similar to 30 nM, similar to 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.

  A series of 3-Substituted amino-4,5-tetramethylene thieno[2,3-d] [1,2,3]-triazine-4(3 (H) under bar )ones have been synthesized and characterized by UV,IR, 1H NMR, elemental and mass spectral analysis. The title compounds were evaluated for their antimicrobial activity by agar diffusion method against four bacteria and three fungi using Ampicillin and Miconazole nitrate as standards. The compounds Villa, IXa, Xa and XIa showed an antimicrobial efficacy considerably greater than the compounds la to Vila with -H, phenyl and electron donating (activating) groups like methyl, ethyl and tolyl substitutions at R. suggesting that lipophillic groups like chloro, fluoro substitution on the phenyl ring plays an important role in enhancing the antimicrobial properties of this class of compounds.From the screening results it can be concluded that the compounds having the lipophillic groups like chlorophenyl and fluorophenyl groups at R exhibited appreciable antimicrobial activities. Whereas, the compounds are having -H, phenyl and electron donating (activating) groups like methyl, ethyl and tolyl substituents at R were less active against all the organisms used.
