Abstract

Saturated and unsaturated 17 �²-aminosteroids are used as intermediates to synthesize biologically active derivatives. Peptide analogs of aminosteroids with various physiological activities such as anti-tumor and anti-arrhythmic have been found, were prepared by adding amino acids to aminosteroids. Mono- and dipeptide derivatives of 17�²-amino-5�±-androstan-3�²-ol were synthesized by N-acylation with N-protected amino acids (N-Cbz-L-Ala-Bt, N-Cbz-L-Val-Bt, N-Cbz-L-Phe-Bt and N-Cbz-L-Ala-L-Val-Bt) and their antiviral activity have been studied. Starting amine, which exhibited anti-arrhythmic activity, was prepared from steroidal saponin - tigogenin using the method developed by us. To conclude, N-protected (�±-aminoacyl) benzotriazoles have been utilized in the successful N-acylation of steroidal amines. Studies of antiviral activities (NIAID) of synthesized mono- and dipeptide derivatives did not reveal significant activities
