摘要

Abstract: A new series of 5, 6-dihydropyrazolo [1, 5-d]-1, 2, 4-triazine-4, 7-diones substituted in the 6-position with various phenyl substituents has been synthesized and found to have activity, owing to their acylating properties, as inhibitors of the serine protease enzymes. Key words: dioxopiperazine, 5-pyrazolecarboxhydrazides cyclization, trichloromethyl chloroformate, protease inhibitors
