Structure–activity relationships of neuropeptide Y Y1 receptor antagonists related to BIBP 3226
摘要:
Analogues of BIBP 3226, (R)-N-alpha-diphenylacetyl-N-(4-hydroxybenzyl)argininamide, were synthesized and investigated for Y-1 antagonism (Ca2+-assay, HEL cells) and binding on Y-1, Y-2 and Y-5 receptors. Replacing the benzylamino by a tetrahydrobenzazepinyl group preserves most of the Y-1 activity. Combination with a N-G-phenylpropyl arginine and a N-alpha-p-biphenyly-lacetyl moiety shifted the NPY receptor selectivity towards Y-5 (C) 2000 Elsevier Science Ltd. All rights reserved.
