Histamine analogues: imidazolylalkylguanidines, synthesis and in vitro pharmacology
摘要:
Impromidine analogues characterized by modified side chains connecting the guanidine and imidazole moieties have been prepared and tested for H-2-agonistic activity on isolated guinea-pig right atrium and for H-1-antagonistic activity on guinea-pig ileum, respectively. 3-(1H-Imidazol-4-yl)propylguanidines with varied cimetidine-like side chain (5a-d) proved to be almost full H-2-agonists and 5-70 times more potent than histamine, whereas compounds with beta- or gamma-methyl branched imidazolylpropyl moiety (5e, 5f, 5h) are only weak partial H-2-agonists. Both unsaturated impromidine analogues (5i, 5j) are full H-2-agonists, the (Z)-configurated compound 5j being about 4 times more potent than the (E)-configurated derivate 5i.
The design of potent, selective, non-covalent, peptide thrombin inhibitors utilizing imidazole as a S1 binding element
摘要:
Modeling of neutral or mildly basic functional groups in the S1 site of thrombin led to the targeting of imidazole as a S1 binding element and correctly predicted the optimal chain length for connecting this group with the S2 and S3 binding elements. Derivatives of 4-(3-aminopropyl)-imidazole can be selective inhibitors of thrombin demonstrating potent anticoagulant activity. (C) 1999 Elsevier Science Ltd. All rights reserved.
