Sf. Victory et al., RELATIVE STEREOCHEMISTRY AND SOLUTION CONFORMATION OF THE NOVEL PACLITAXEL-LIKE ANTIMITOTIC AGENT EPOTHILONE-A, Bioorganic & medicinal chemistry letters, 6(7), 1996, pp. 893-898
A nearly complete set of H-1-H-1 coupling constants and NOEs were dete
rmined for the novel paditaxel-like antimitotic agent epothilone A fro
m phase sensitive DFQ COSY and NOESY experiments in 75% DMSO-d(6)/D2O.
This data was employed as distance constraints for molecular modeling
studies. Molecular dynamic simulations were carried out on a complete
series of diastereoisomers, and the results show only two relative st
ereochemistries to be in agreement with the NOE data. Copyright (C) 19
