SAR studies on bicalutamide, enobosarm and enzalutamide analogues, functionalised with polyfluorinated groups, is presented. Among the novel bicalutamide and enobosarm derivatives synthesised, several displayed significantly improved in vitro anticancer activity, with IC50 values in the low micromolar range against four different prostate cancer cell lines (LNCaP, VCaP, DU-145 and 22Rv1), showing up
提出了用多氟基团官能化的比卡鲁胺,烯醇和恩杂鲁胺类似物的SAR研究。在合成的新型比卡鲁胺和enobosarm衍生物中,有几种显示出显着改善的体外抗癌活性,对四种不同的前列腺癌细胞系(LNCaP,VCaP,DU-145和22Rv1)的IC 50值在低微摩尔范围内,最高显示48与父代结构相比增加了三倍。特别地,发现SF 5 enobosarm类似物是最有效的化合物,完全的AR拮抗剂并且具有有利的ADME特性。对最有前途的化合物(48a)进行了体内评估 在PC异种移植小鼠模型(22Rv1)中的功效,其结果可与护理标准多西紫杉醇相媲美。
