The ozonation products of cholesterol, which are of interest as possible biomarkers of O3 exposure, were studied by derivatization with 2,4-dinitrophenylhydrazine (DNPH). The DNPH derivatization of 3 beta-hydroxy-5-oxo-5,6-secocholestan-6-al (2) produces the expected trans (3b) and cis (3c) derivatives of 3 beta-hydroxy-5-oxo-5,6-secocholestan-6-al, and the unexpected DNPH derivative of 3,5-dihydr

critical to avoid the formation of cholesterol aldehydes through Hock cleavage of 5α-hydroperoxycholesterol. In conclusion, PBH can be used as an efficient fluorescent probe for the detection/quantification of cholesterol aldehydes in biological samples. Its analysis by HPLC coupled to a fluorescent detector provides a sensitive and specific way to quantify cholesterol aldehydes in the low femtomol range

Using cholesterol as a starting material, two novel steroidal thiadiazole derivatives possessing a structure of A-homo lactam and a B-nor steroidal skeleton were designed and synthesized by six steps of reactions, and their antiproliferativeactivities were assayed against various cancer cell lines. The result shows that compound 7b displays an excellent selective inhibition to A-549 (human lung carcinoma)
