The invention relates to detection of cholesterol ozonation products that are generated by atherosclerotic plaque material, and to methods of detecting vascular conditions that relate to the accumulation and oxidation of cholesterol.

The structure of the product formed in the course of the reaction of cholesterol acetate and other Δ5-steroids with ozone in alcohol-containing solvents has been revised. The solvent-participated products are hydroperoxides, 5α-hydroperoxy-7α-alkoxy-5α-B-homo-6-oxasteroids 3 and not the previously claimed cyclic hemiperacetals, 5α-hydroxy-7a-alkoxy-B-dihomo-6,7-dioxacholestane derivatives 1. The final
As illustrated herein, cholesterol is oxidized when it is present in atherosclerotic plaques. This reaction generates cytotoxic cholesterol oxidation or ozonation products. The present application is directed to the products of cholesterol ozonation, binding entities directed against such products, and methods of using such binding entities and cytotoxins to treat a variety of diseases.
