3-Pyridylisoxazoles as prototypes of antiaggregatory agents

详细

A series of 5-alkyl-3-pyridylisoxazoles was synthesized using the 3-(3-pyridyl)isoxazole scaff old. All compounds of the series possessed antiaggregatory activity in the concentration range of 6•10^–6–6•10^–4 mol L^–1. Analysis of the experimental data on the antiaggregatory activity revealed the presence of spatial constraints for the alkyl substituents in position 5 of the isoxazole ring. 5-Alkyl-3-(3-pyridyl)isoxazoles are rather selective for platelet membrane receptors.
