The new modified steroidal derivatives thieno[2′,3′:2,3]cholestan 18 and thieno[2′,3′:2,3]-androstan 20 were synthesized and examined against LR, the corresponding thiazaphosphorinothieno steroidal derivatives 23 and 24 were isolated respectively. The in vitro biological activity of some newly synthesized compounds against bacteria, yeast, and fungi
