4-AMINO-3-MERCAPTO-1,2,4-TRIAZOLES

摘要

This invention claims the utility of two structural variants of functionalized 4-amino-3-mercapto-1,2,4-triazoles as inhibitors of nitric oxide synthase (NOS) and as inhibitors of malignant cell growth. This fundamental molecular construct operates as a heterocyclic mimic of the open-chain N-aminoarginines (or N-aminoguanidines) previously established as NOS inhibitors. A convenient bioassay method, using PAM 212 keratinocytes for detection and quantification of relative NOS inhibition potential in a series of candidate drugs, is described as is a bioassay for growth inhibition.
