目的改善抗腫瘤藥物安吖啶的藥效學(xué)性質(zhì)以期增強(qiáng)其靶向抗腫瘤作用。方法基于拼合設(shè)計(jì)原理,以安吖啶為原料,經(jīng)與吡啶-2-過(guò)硫乙醇偶聯(lián)、與巰基多胺硫交換反應(yīng)合成安吖啶-二硫鍵-胺基綴合物;采用MTT法測(cè)試目標(biāo)化合物8a(m=1,R=H)對(duì)人肝癌細(xì)胞(HepG2)的體外生長(zhǎng)抑制活性;在H22肝癌細(xì)胞移植的荷瘤小鼠模型上測(cè)試化合物8a的體內(nèi)抗腫瘤作用。結(jié)果與結(jié)論合成了5個(gè)未見(jiàn)文獻(xiàn)報(bào)道的安吖啶綴合物,目標(biāo)化合物的結(jié)構(gòu)經(jīng)核磁共振氫譜、核磁共振碳譜及高分辨質(zhì)譜確證。體外試驗(yàn)結(jié)果表明,化合物8a在谷胱甘肽作用下發(fā)生二硫鍵降解并釋放出安吖啶原藥;高谷胱甘肽水平能夠增強(qiáng)化合物8a對(duì)人肝癌細(xì)胞HepG2的生長(zhǎng)抑制作用;體內(nèi)活性試驗(yàn)表明,在1.25 mg·kg-1劑量下化合物8a對(duì)荷瘤小鼠的腫瘤(hepatoma H22)生長(zhǎng)抑制率達(dá)到51.3%,荷瘤小鼠的生存時(shí)間明顯延長(zhǎng)。■
