Pteridines. Part CXI. Pteridine-based photoaffinity probes for nitric oxide synthase and aromatic amino acid hydroxylases

Various 6-substituted pteridines and 5,6,7,8-tetrahydropterins carrying photolabile functions at the side chain (see 7, 20-22, 34-36, 38, and 39) as well as at the 5-position (see 27-29) were synthesized from pterin and from 6-phenylpterin (1) and 6-(hydroxymethyl)pterin (10). Attachment of the photoaffinity labels via ester bonds required a special protecting-group strategy based upon acid-labile (see 30-33) and β-eliminating blocking groups (see 17-19). The 6-(4-azidophenyl)pterin (7) was obtained from 6-phenylpterin (1) via intermediates 2 and 4-6, due to the low solubility of simple pterins in general. The pteridine derivatives 21, 22, 25, 26, 28, 29, 32, 33, 35, 36, 38, and 39 were screened as inhibitors of neuronal (type I) NO synthase (see Table) from porcine cerebellum. of which 22, 35, 36, and 38 showed interesting inhibitory activity with similar potency and effectiveness.
