Synthesis of pyridazino[3,4-b][1,5]benzodiazepin-5-ones and their biological evaluation as non-nucleoside HIV reverse transcriptase inhibitors

Starting from 3,6-dichloro-N-(2-chloro-5-nitrophenyl)-pyridazine-4-carboxamine (7) a series of 6,11-dialkylated pyridazino-[3,4-b][1,5]benzodiazepin-5-ones with a 3-chloro-8-nitro, 8-amino, 8-acetylamino, or 8-chloro substitution pattern was prepared via N-alkyl-3-alkylamino-6-chloro-N-(2-chloro-5-nitrophenyl)-pyridazine-4- carboxamides. The new compounds were screened as non-nucleoside reverse transcriptase inhibitors. The influence of the substitution pattern in compounds 10-13 on inhibitory potency is discussed.
