    • The instant invention provides for a method of inhibiting prenyl-protein transferases and treating cancer which comprises administering to a mammal a prenyl-protein transferase inhibitor which is an inhibitor of cellular processing of the H-Ras and K4B-Ras proteins. The invention in particular provides for a method of inhibiting farnesyl-protein transferase and geranylgeranyl-protein transferase type I by administering a compound that is a dual inhibitor of both of those prenyl-protein transferases. The instant invention als provides for a method of identifying such a compound, the method comprising an assay whose readout is a consequence of the biological activity or inhibition of that activity of the Ras protein, thus providing convenient identification of compounds that inhibit cellular processing of the H-Ras and K4B-Ras proteins.
    • 本发明提供了一种抑制异戊二烯基蛋白转移酶并治疗癌症的方法,该方法包括给予哺乳动物异戊二烯基 - 蛋白转移酶抑制剂,该抑制剂是H-Ras和K4B-Ras蛋白细胞加工的抑制剂。 本发明特别提供了通过施用作为那些异戊二烯基蛋白转移酶的双重抑制剂的化合物来抑制法尼基蛋白转移酶和香叶基香叶基蛋白转移酶I型的方法。 本发明还提供了一种鉴定这种化合物的方法,该方法包括一种检测方法,该方法的读数是Ras蛋白质的该活性的生物活性或抑制作用的结果,因此提供了方便鉴定抑制细胞加工 H-Ras和K4B-Ras蛋白。
