Hartree-Fock and density functional theory (B3LYP) calculations were applied to the study of the anti-tumor drug FR900482 and some of its analogs. Optimum geometries were obtained and it was found that the most stable conformations feature the N-H bond of the aziridine ring nitrogen “down” and the oxygen bridge and aziridine nitrogen “up”. It was also found that the analog containing NH(2) (in place of the -CHO of the natural product) is the most prone to oxidation.
