1999 While the N-hydroxylation of the guanidine involves the usual monooxygenase activity of cytochrome P-450 (Clement et al., Biochem Pharmacol 46: 2249-2267, 1993), the resultant N-hydroxyguanidine

2005 The k(cat) values of NO production from the oxidation by iNOS of the studied N-hydroxyguanidines were found to vary independently of their affinity for the protein. hydroxyguanidine 77-96 nitric oxide synthase 2 Homo sapiens 57-61 15955074-11 2005 These data indicate that a key factor for efficient oxidation of a guanidine by iNOS to NO is the ability of the corresponding N-hydroxyguanidine to bind to the active site without being too rapidly released before its further oxidation. hydroxyguanidine 127-145 nitric oxide synthase 2 Homo sapiens 80-84 15955074-12 2005 This explains why 4,4,4-trifluorobutylguanidine is so far the best non-alpha-amino acid guanidine substrate of iNOS with formation of NO, because the k(off) (app) of the corresponding N-hydroxyguanidine is particularly low. hydroxyguanidine 184-202 nitric oxide synthase 2 Homo sapiens 111-115 12437343-4 2002 However, the former binds to nNOS in an unexpected fashion, thus providing new insights into the mechanism on

with those of the previously described corresponding complexes of microperoxidase (MP-8) suggests that, in both cases, N-hydroxyguanidines bind to iron(III) via their oxygen atom after deprotonation
