to the triazolone/side chain region of the scaffold. Our overall results suggest that the triazolone/side chain region can be replaced with various functionalities (hydrazine carboxamides and meta-substituted amides) resulting in improved potency when compared to ITZ. Our studies also indicate that the stereochemical orientation of the dioxolane ring is important for both potent Hh pathway inhibition
食品和药物管理局批准的抗真菌药伊曲康唑(ITZ)因其新颖的生物学特性而得到了越来越多的研究。特别是,ITZ抑制了刺猬(Hh)信号传导途径,并有潜力用作针对几种Hh依赖性恶性肿瘤的抗癌化学疗法。我们已经通过设计,合成和评估新型des-triazole ITZ类似物(结合了对支架的三唑酮/侧链区域的修饰)扩展了对作为Hh途径抑制剂的ITZ类似物的研究。我们的总体结果表明,与ITZ相比,三唑酮/侧链区可以被各种官能团取代(肼甲酰胺和间位取代的酰胺),从而提高了效力。我们的研究还表明,二氧戊环环的立体化学取向对于有效的Hh途径抑制和化合物稳定性均很重要。最后,我们的研究表明,可以在功能和立体化学方面成功修饰ITZ支架,以进一步提高其抗Hh效能和理化特性。
