Quaternary ammonium salts of phenanthroindolizidine and phenanthroquinolizidine alkaloids as hypoxia-targeted anticancer agents
A compound having a structure of formula (I): ##STR00001##
Wherein each of R.sub.1A, R.sub.1B, R.sub.1C, R.sub.1D, R.sub.1E and R.sub.1F is independently selected from the group consisting of a hydrogen atom, a hydroxide group, and a substituted or unsubstituted C.sub.1-C.sub.8 alkoxy group, R.sub.2 is selected from the group consisting of a hydrogen atom and a hydroxide group, R.sub.3 is hydrogen atom, R.sub.4 is selected from the group consisting of a hydrogen atom, a C.sub.1-C.sub.3 alkyl group, and a C.sub.1-C.sub.3 fluoroalkyl group, R.sub.5 is selected from the group consisting of a hydrogen atom, a C.sub.1-C.sub.6 alkyl, and a C.sub.1-C.sub.6 fluoroalkyl, n is 1 or 2, and X is a negatively charged anion. Removal of the substituted nitroimidazole affords a phenanthroindolizidine or phenanthroquinolizidine alkaloid derivative. The compound is used in a pharmaceutical composition and a method of treating a proliferative disease.
