In the present work we describe the synthesis and antiproliferative evaluation of a focused library of 30 novel oxazolidines designed by modification of N-substituent, by ring variation, by alkyl variation or by extension of the structure. It was noted that carbamate and N,O-aminal groups were essential for activity. In general, replacement of the phenyl ring with pyridinyl was not tolerated. However
在本工作中,我们描述了30种新颖的恶唑烷的聚焦文库的合成和抗增殖评价,这些新恶唑烷通过修饰N-取代基,通过环变异,通过烷基变异或通过结构扩展来设计。注意到氨基甲酸酯基团和N,O-氨基基团对于活性是必不可少的。通常,不容许用吡啶基取代苯环。然而,在第一苯环的3-或4-位引入具有适当间隔基的第二苯环通常会增强细胞毒性。在所有制备的化合物中,有24种是最有效的化合物,在五种癌细胞系中有四种具有活性,并且分别比针对HL60和JURKAT细胞的先导化合物强5倍和10倍。此外,它还显示了对铅具有抗性的MCF-7和HCT-116细胞的相关活性。此外,有24种抗VERO的抗增殖活性很小,表明对正常细胞的毒性较低。因此,该化合物具有被开发为抗癌剂的潜力。
