A method of inhibiting Ras function and therefore inhibiting the abnormal growth of cells is disclosed. The method comprises the administration of a compound of Formula 1.0: ##STR1## to a biological system. In particular, the method inhibits the abnormal growth of cells in a mammal such as a human being. Novel compounds of formulas 5.0, 5.1 and 5.2, wherein R is --C(R.sup.20)(R.sup.21)(R.sup.46), and 5.3, 5.3A and 5.3B, wherein R is --N(R.sup.25)(R.sup.48), are disclosed. Also disclosed are processes for making 3-substituted compounds of Formulas 5.0, 5.1, 5.2 and 5.3. Further disclosed are novel compounds which are intermediates in the process for making 3-substituted compounds of Formulas 5.0, 5.1, 5.2 and 5.3.
本发明公开了一种抑制Ras功能并因此抑制细胞异常生长的方法。该方法包括向生物系统中注入化合物1.0的化合物:##STR1## 。特别是,该方法抑制哺乳动物(如人类)中细胞的异常生长。本发明还公开了公式5.0、5.1和5.2的新化合物,其中R为--C(R.sup.20)(R.sup.21)(R.sup.46),以及公式5.3、5.3A和5.3B的新化合物,其中R为--N(R.sup.25)(R.sup.48)。还公开了制备公式5.0、5.1、5.2和5.3的3-取代化合物的方法。此外,还公开了制备公式5.0、5.1、5.2和5.3的3-取代化合物的过程中的新型中间体化合物。
