Conformational analysis of 2-[alpha-D-lyxofuranosyl] maleimide

ABSTRACT

2-[alpha-D-Iyxofuranosyl] maleimide is one of the analogues of the alpha anomer of the antitumour antibiotic showdomycin. Conformation of 2-[alpha-D-lyxofuranosyl] maleimide on the basis of potential energy calculation is reported. These calculations indicate that the drug has allowed conformation in the region of omega = 0° to 20°, omega = 80° to 120° and at omega = 360°. The region of omega = 140°-340° is not allowed. The most feasible position for the drug to interact with receptor would be at minimum potential energy in the regions from omega = 0° to 20°, omega = 80° to 120° and at omega = omega = 360°
