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))。
