polyhydroxylated steroids has been systematically investigated. The enzyme showed a mark preference forthe alcoholic moieties on the A ring and on the steroidal side chain, making it possible the selective acylation at the positions 3 or 21 of polyhydroxy steroids. Acylation with the synthetically useful ester choloroacetate and levulinate was also accomplished, whereas esterification with benzoate and

Three novel isomeric supramolecular dehydroepiandrosterone appended 1,2,3-triazole-based potential gelators were synthesized. Their ability to form gels in different solvents was studied experimentally as well as at the molecular level by means of molecular dynamics and quantum chemistry. The conformational changes and binding sites of the molecules were indicated and discussed. While the gelator molecule
