Steroidal lactam quinoxalines, lactam indoles, and lactam thiazoles
Journal of Chemical & Engineering Data, 1987Steroidal lactams have been reported to possess unusual anticancer activity ( I , 2). On the other hand, steroidal quinoxaline, indole, and thiazole derivatives present biological action (3). I t was of interest to combine these three heterocyclic nuclei to the steroid lactam and to study their biological activity.

Abstract The ability of lactams to undergo ring-opening polymerization largely depends on the ring size, substitution and presence of heteroatoms in the lactam ring. The heat of polymerization varies with ring size from practically zero up to 20 kcal/mol. Also the entropy of polymerization can vary in a much broader range than for, e.g.
