    抗HIV和抗癌藥物設計跨進一大步

    美國維吉尼亞聯邦大學 Massey 醫學中心(Virginia Commonwealth University Massey Cancer Center)的研究者利用含鉑的小分子,成功抑制與HIV和癌症有關的轉錄蛋白家族。
     
    這項結果在5月30日的journal Chemistry & Biology中發表。研究者觀察到,HIV NCp7的鋅手指(zinc finger)結構會裸露出來,和鉑作用。如此鋅手指結構就無法再和DNA結合,HIV NCp7也失去了他的生物功能。研究顯示,HIV NCp7和HIV的複製有關。若研究者能成功的抑制HIV NCp7的鋅手指區域,就能有效阻斷病毒複製和散播。
     
    「當我們用先期的藥物去對抗病毒時,在一段時間之後總會失效。」Nicholas Farrell博士表示。科學家希望這項發現可以幫助發展鎖定在攻擊蛋白的「鋅手指」結構區域藥物,來對抗HIV或癌症。若要設計出能夠遮蔽或結合蛋白鋅手指區域的藥物,則要往對該蛋白胜序列有高親和力的方向進行。
     
    研究者希望研發出來更多臨床藥物,能夠有效、並將副作用降到最低的,解決現在藥物的問題。
