  The discovery of potent blockers of the canonical transient receptor channels, TRPC3 and TRPC6, based on an anilino-thiazole pharmacophore

  摘要：

  Lead optimization of piperidine amide HTS hits, based on an anilino-thiazole core, led to the identification of analogs which displayed low nanomolar blocking activity at the canonical transient receptor channels 3 and 6 (TRPC3 & 6) based on FLIPR (carbachol stimulated) and electrophysiology (OAG stimulated) assays. In addition, the anilino-thiazole amides displayed good selectivity over other TRP channels (TRPA1, TRPV1, and TRPV4), as well as against cardiac ion channels (CaV1.2, hERG, and NaV1.5). The high oxidation potential of the aliphatic piperidine and aniline groups, as well as the lability of the thiazole amide group contributed to the high clearance observed for this class of compounds. Conversion of an isoquinoline amide to a naphthyridine amide markedly reduced clearance for the bicyclic piperidines, and improved oral bioavailability for this compound series, however TRPC3 and TRPC6 blocking activity was reduced substantially. Although the most potent anilino-thiazole amides ultimately lacked oral exposure in rodents and were not suitable for chronic dosing, analogs such as 14-19, 22, and 23 are potentially valuable in vitro tool compounds for investigating the role of TRPC3 and TRPC6 in cardiovascular disease.

  摘要：

  bacillamide（一种海洋来源的生物活性类胰蛋白酶生物碱）的十四种类似物的合成已通过高效的收敛途径完成。本无溶剂方案涉及在初始步骤中形成噻唑环，然后在2-羟基-4,6存在下，取代的2-烷基/芳基/杂芳基/氨基/氨基芳基噻唑-4-羧酸乙酯与色胺之间进行酰胺偶联。 -二甲基嘧啶，一种固相催化剂，可产生N- [2-（1 H-吲哚-3-基）乙基] -2-烷基/芳基/杂芳基/氨基/氨基芳基噻唑-4-羧酰胺作为bacillamide类似物，在噻唑环的2位具有结构变化。使用比色细胞增殖测定法评估了巴西酰胺及其类似物对三种癌细胞系（HCT-116，MDA-MD-231和JURKAT细胞系）的细胞毒活性。化合物17a和17b对这些细胞系表现出有效的抗细胞增殖活性，IC 50值分别在〜3.0μM和〜0.1-0.6μM范围内。初步的作用机制研究表明，这些化合物可启动caspase依赖性细胞凋亡。另外，化合物16d，16f，17a和17d

  In a continued effort to improve upon the previously published 4-substituted methoxybenzoyl-aryl-thiazole (SMART) template, we explored chemodiverse “B” rings and “B” to “C” ring linkage. Further, to overcome the poor aqueous solubility of this series of agents, we introduced polar and ionizable hydrophilic groups to obtain water-soluble compounds. For instance, based on in vivo pharmacokinetic (PK)

  为了继续改进之前发表的 4-取代甲氧基苯甲酰基-芳基-噻唑 (SMART) 模板，我们探索了化学多样性的“B”环和“B”到“C”环的连接。此外，为了克服该系列试剂水溶性差的问题，我们引入了极性和可离子化的亲水基团以获得水溶性化合物。例如，基于体内药代动力学 (PK) 研究，设计并合成了一种口服生物可利用的苯基-氨基-噻唑 (PAT) 模板，其中在化合物1 的“A”和“B”环之间插入了一个氨基键. PAT 模板通过抑制微管蛋白聚合保持了对癌细胞系的纳摩尔 (nM) 范围效力，并且在体外不易受到 P-糖蛋白介导的多药耐药性的影响，与 SMART 模板相比，溶解度和生物利用度显着提高 ( 45a – c (PAT)与1（智能））。
