Synthesis and Biological Activity of Several Modified 5α-Androstanolone Derivatives.

Several new N-containing epiandrosterone derivatives modified by phenylacetic acid chloride were synthesized for biological activity studies. Compounds with antiviral activity were discovered among them and 3ß-hydroxy-1'-aryl-3'-methyl-5'-androstano[17,16-d]pyrazolines prepared by us earlier.
