Synthesis and activities of new arylsulfonamido thromboxane A2 receptor antagonists
摘要:
New benzoic, benzeneacetic and thiazole-4-acetic acids bearing an arylsulfonamido alkyl or alkylhetero side chain were synthesized and tested in vitro for affinity for human platelet thromboxane A2 receptors and inhibition of U46619-induced rat aortic ring contraction. Influence of substitution patterns, chain length and presence of heteroatoms were studied and compounds within a 30 nmol range for inhibition of U46619-induced contractions were found. One of the most potent, 2-[(4-chloro-benzenesulfonylamino-ethyl)thio] thiazole-4-acetic acid (VII-4) was orally active (1 mg/kg), as evidenced by the inhibition of U46619-induced platelet aggregation in guinea pigs, ex vivo.

inhibition assay the prepared inhibitors showed good inhibition. While the monovalent GM1 mimic showed the expected inhibition in the 200 microM range the multivalent scaffolds led to increased binding. The tetravalent compound was shown to be 440-fold more potent than its monovalent counterpart. The octavalent analog, however, was the most potent compound as determined using an ELISA assay.
The synthesis of lactose-containing dendrimers is described; the dendrimers used were based on the 3,5-di(2-aminoethoxy)benzoic acid repeating unit. Dendrimers of generation 1, 2, and 3 − containing 2, 4, and 8 endgroups, respectively − were used. These were coupled to lactose isothiocyanate, resulting in thiourea-linked glycodendrimers, characterized by 13C NMR and mass spectrometry. The lactose-functionalized

A novel series of N1 substituted tetrazole amides were prepared and showed to be potent growth hormone (GH) secretagogues. Among them, hydroxyl containing analog 31 displayed excellent in vivo activity by increasing plasma GH 10-fold in an anesthetized IV rat model. (c) 2008 Elsevier Ltd. All rights reserved.
