Forty-six new compounds were synthesized on the basis of our knowledge of the 3-haloacylamino benzoylurea (HBU) series. Structure-activity relationship (SAR) analysis indicates that (i) the configuration of the chiral center in 1 (JIMB01) is not indispensable for the activity, (ii) the phenyl ring is essential, and (iii) a substitution at the 6-position of the phenyl ring with a halogen enhances the
根据我们对3-卤代酰基氨基苯甲酰脲(HBU)系列的了解,合成了46种新化合物。结构-活性关系(SAR)分析表明,(i)1中的手性中心构型(JIMB01)对于该活性不是必不可少的;(ii)苯环是必不可少的;和(iii)6-位上的取代基苯环在卤素上的位置提高了活性。在类似物中,带有6-氟取代基的11e和14b显示出对九种人类肿瘤细胞系的有效活性,其中包括CEM(白血病),Daudi(淋巴瘤),MCF-7(乳腺癌),Bel-7402(肝癌),DU- 145(前列腺癌),PC-3(前列腺癌),DND-1A(黑色素瘤),LOVO(结肠癌)和MIA Paca(胰腺癌),IC 50值为0.01至0.30 microM。14b在裸鼠中抑制了人类肝癌86%的体积。14b的机制是抑制微管组装,随后是M期阻滞,bcl-2失活,然后是细胞凋亡。我们认为14b有希望用于进一步的抗癌研究。
