Homologation of the Alkyl Side Chain of Antimitotic Phenyl 4-(2-Oxo-3-alkylimidazolidin-1-yl)benzenesulfonate Prodrugs Selectively Targeting CYP1A1-Expressing Breast Cancers Improves Their Stability in Rodent Liver Microsomes

Phenyl 4-(2-oxo-3-alkylimidazolidin-1-yl)benzenesulfonates (PAIB-SOs) are a new family of antimitotic prodrugs bioactivated in breast cancer cells expressing CYP1A1. In this study, we report that the 14C-labeled prototypical PAIB-SO [14C]CEU-818 and its antimitotic counterpart [14C]CEU-602 are distributed in whole mouse body and they show a short half-life in mice. To circumvent this limitation, we
苯基 4-(2-oxo-3-alkylimidazolidin-1-yl)benzenesulfonates (PAIB-SOs) 是一个新的抗有丝分裂前药家族,在表达 CYP1A1 的乳腺癌细胞中被生物激活。在这项研究中,我们报告了14 C 标记的原型 PAIB-SO [ 14 C]CEU-818 及其抗有丝分裂对应物 [ 14 C]CEU-602 分布在整个小鼠体内,并且它们在小鼠体内的半衰期较短. 为了规避这一限制,我们评估了 PAIB-SOs 的咪唑啉-2-one 部分的烷基侧链同系化的影响。我们的研究表明,PAIB-SO 具有n-戊基侧链在纳摩尔到低微摩尔范围内表现出抗增殖活性,并且对 CYP1A1 阳性乳腺癌细胞具有高选择性。此外,最有效的正戊基 PAIB-SO 对啮齿动物肝微粒体的稳定性明显更高。此外,PAIB-SO 10和14在绒毛尿囊膜 (CAM) 测定中显示出显着的抗肿
