structural optimization toward a previously disclosed Src inhibitor, compound 1, which showed high potency in the treatment of triple negative breast cancer (TNBC) both in vitro and in vivo but had considerable toxicity. A series of 3-(phenylethynyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine derivatives were synthesized. In vitro cell-based phenotypic screening together with in vivo assays and structure–activity
本文中,我们报告了针对先前公开的Src抑制剂化合物1进行结构优化的复杂过程,该化合物在体外和体内均显示出对三阴性乳腺癌(TNBC)的高治疗能力,但具有相当大的毒性。合成了一系列的3-(苯基乙炔基)-1 H-吡唑并[3,4- d ]嘧啶-4-胺衍生物。最终基于体外细胞的表型筛选,以及体内测定和结构-活性关系(SAR)研究最终导致了N-(3-((4-氨基-1-(反式-4-羟基环己基)-1 H)的发现-吡唑并[3,4- d ]嘧啶-3-基)乙炔基)-4-甲基苯基)-4-甲基-3-(三氟甲基)苯甲酰胺(13an)。13an是一种多激酶抑制剂,可有效抑制Src(IC 50 = 0.003μM),KDR(IC 50 = 0.032μM)和几种参与MAPK信号转导的激酶。该化合物在体外和体内均显示出有效的抗TNBC活性,并具有良好的药代动力学特性和低毒性。还研究了抗TNBC的作用机理。总体而言,本研究获
