3,4-Dihydro-1-isoquinolinamines: A novel class of nitric oxide synthase inhibitors with a range of isoform selectivity and potency

3-Phenyl-3,4-dihydro-1-isoquinolinamine is a weak inhibitor of iNOS and nNOS. Structural variation of 5a results in inhibitors with a range of potency and selectivity for the NOS enzymes, including a potent and very selective iNOS inhibitor 5j.
