Heterocyclic Amplifiers of Phleomycin. VI. Some Phenylpurines, Phenylpteridines, Phenylquinazolines and Related Compounds

Abstract

Synthetic routes are described to a series of 2-, 6- and 8- phenylpurines , each with an appropriate S-or NH-linked side chain elsewhere in the molecule; to 2- and 4-phenylpteridines, each with a similar side chain and some with two additional C-methyl groups, to 2- and 4-phenylquinazolines, each equipped with an analogous side chain; and to two pyridinyl analogues of the above. Three of the above components are shown to have considerable activity as amplifiers of phleomycin -G in an in vitro bacterial system.
