Discontinued Product

Unfortunately 2-Amino-4-methylpyridine (Cat. No. 1020) has been withdrawn from sale for commercial reasons.
Cat.No. 1020 - 2-Amino-4-methylpyridine | CAS No. 695-34-1
Description: iNOS inhibitor

Biological Activity

A potent inhibitor of iNOS derived from mouse RAW 264.7 cells (IC50 = 6 nM), although less potent on human recombinant NOS isozymes with IC50 values of 100, 40 and 90 nM at nNOS, iNOS and eNOS respectively. Active in vivo, it shows 6.9-fold selectivity for iNOS vs. eNOS in conscious rats.
