Abstract: A method of inhibiting Ras function and therefore inhibiting cellular growth is disclosed. The method comprises the administration of a novel compound of the formula (Ia), (Ib) or (Ic) ##STR1## wherein: R and R.sup.1 are H, alkyl, halogeno, OH, alkoxy, NH.sub.2, alkylamino, dialkylamino, CF.sub.3, SO.sub.3 H, CO.sub.2 R.sup.3, NO.sub.2, SO.sub.2 NH.sub.2, or CONHR.sup.4 ;n is 0 or 1;R.sup.2 is a group of the formula R.sup.5 C(O)--, R.sup.5 CH.sub.2 C(O)--, R.sup.5 C(R.sup.6).sub.2 C(O)--, R.sup.5 SO.sub.2 --, R.sup.5 CH.sub.2 SO.sub.2 --, R.sup.5 SCH.sub.2 C(O)--, R.sup.5 OC(O)--, R.sup.5 NHC(O)--, R.sup.5 C(O)C(O)-- or R.sup.5 SC(O)--;R.sup.5 is alkyl, aryl, arylalkyl, arylalkenyl, heteroaryl, heteroarylalkyl, heteroarylalkenyl or heterocycloalkyl; andR.sup.6 is alkyl or C(R.sup.6).sub.2 is a carbocyclic ring;or pharmaceutically aceptable salts thereof.

Abstract: 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.sub.25)(R.sub.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.
