ABSTRACT:
Derivatives of camptothecin are disclosed and are represented by the general formula: ##STR1## wherein when R.sub.2 is H, R.sub.1 is a C.sub.2 -C.sub.4 alkyl group, a C.sub.6 -C.sub.15 alkyl group, a C.sub.3 -C.sub.8 cycloalkyl group, a C.sub.2 -C.sub.15 alkenyl group or a C.sub.2 -C.sub.15 epoxy group; and when R.sub.2 is a nitro group, R.sub.1 is a C.sub.1 -C.sub.15 alkl group, a C.sub.2 -C.sub.15 alkenyl group, a C.sub.3 -C.sub.8 cycloalkyl group, or an epoxy group. Processes for making these derivatives and for using them in cancer treatment are also disclosed.
