Abstract
This invention provides a compound having the formula: ##STR1## wherein: (A) n=2-4; PA1 (B) R.sub.1 and R.sub.2 are the same or different and selected from the group consisting of H, (C.sub.1 -C.sub.3) alkyl, --CH.sub.2 CH.sub.2 OH, --CH.sub.2 CH.sub.2 NH.sub.2, and --CH.sub.2 CH.sub.2 N(CH.sub.3).sub.2 or R.sub.1 and R.sub.2 are alkyl moieties which are taken together to form a 4- to 7- membered ring; PA1 (C) R.sub.3 is selected from the group consisting of H, --CH.sub.3, --CH.sub.2 CH.sub.3, and --CH.sub.2 CH.sub.2 NH.sub.2 ; PA1 (D) Y is a heterocyclic radical having 5-14 atoms, located at the 2- or 3- position of the pyridoquinazolinone nucleus, in which 1-3 of the heterocyclic ring atoms are independently nitrogen, oxygen, or sulfur; wherein Y may be optionally mono-, di-, or tri- substituted with --OR.sub.4, --NR.sub.5 R.sub.6, --CO.sub.2 H, --CO.sub.2 R.sub.4, or phenyl; PA1 R.sub.4 is H or (C.sub.1 -C.sub. 4) straight-chain alkyl; PA1 R.sub.5 and R.sub.6 are the same or different and are selected from the group consisting of H, (C.sub.1 -C.sub.4) straight-chain alkyl, --CH.sub.2 CH.sub.2 OH, --CH.sub.2 CH.sub.2 NH.sub.2, and --CH.sub.2 CH.sub.2 N(CH.sub.3).sub.2 or R.sub.5 …
