Synthesis and Biological activity of kappa opioid receptor agonists. Part 2: Preparation of 3-aryl-2-pyridone analogues generated by solution- and solid-phase parallel synthesis methods
摘要:
New analogues of the previously described 3-aryl pyridone KOR agonists have been synthesised by parallel synthetic methods, both in solution- and with solid-phase chemistry, making use of the well known and versatile Mitsunobu, Suzuki and Buchwald reactions. Opioid receptor binding data for the compounds produced is reported. (C) 2003 Elsevier Science Ltd. All rights reserved.
A compound of the general formula (M.sup.1).sub.n --Q--(M.sup.2).sub.1-n --L--A I wherein: n is 0 or 1; M.sup.1 is an amino group; Q is an aromatic heterocyclic group containing a basic nitrogen atom; M.sup.2 is an imino group; L is a template group; and A is an acidic group, or an ester or amide derivative thereof, or a sulphonamide group; and pharmaceutically acceptable salts and pro-drugs thereof, for use in the treatment of a disease in which platelet aggregation mediated by the binding of adhesion molecules to GPIIb-IIIa is involved. Novel compounds are also disclosed.
The invention concerns .alpha.-aminoacyl derivatives of phenyl-, phenoxy-, thiophenoxy- and phenylsulphinylalkanoic acids together with their amides, esters and pharmaceutically acceptable salts; processes for their preparation; and pharmaceutical compositions for therapeutic use in inhibiting the formation of thrombi and also in reducing the persistence of thrombi formed in the blood of warm blooded animals. Representative compounds of the invention are methyl 4-(aminoacetyl)phenoxyacetate, 4-(aminoacetyl)phenoxyacetic acid and methyl 4-(aminoacetyl)-thiophenoxyacetate, preferably as their hydrochlorides.

The serine protease urokinase plasminogen activator (uPA) is thought to play a central role in tumor metastasis and angiogenesis. Molecular modeling studies suggest that 5-thiomethylthiopheneamidine inhibits uPA by binding at the S1 pocket of the active site. Further structure based elaboration of this residue resulted in a novel class of potent and selective inhibitors of uPA. (C) 2001 Elsevier Science Ltd. All rights reserved.
