Based on computer modeling of the active site of nitricoxidesynthases (NOS), a series of 10 amidine compounds (9-18) was designed including potentialinhibitors that involve the coordination of side-chain functional groups with the iron of the heme cofactor. The most potent and selective compound was the methylthio amidine analogue 9, which was more potent than L-nitroarginine with 185-fold selectivity
distamycin have been synthetized. They have been designed starting from 2-((aminomethyl)-thiazole-4 carboxylic acid, gly (Thz), a key element in the structure of highly cytotoxic natural peptides. In the structure of the three new compounds, this unit replaces N-methyl pyrrole carboxylic acid which seems to play a crucial role in DNA base sequence recognition by the parent natural agents.
