Abstract :

Recently, steroidal hydrazones have been receiving extensive attention of scientists because they have shown to exhibit antibacterial, antiviral and anticancer activities. Previously synthesized by us, some 5?±-steroidal hydrazones have shown high antitubercular and antiviral activities. In order to find new potential bioactive compounds, hydrazones of 5?±-androstane series have been synthesized. The starting ketones, 3?±-hydroxy-5?±-androst-9(11)-en-17-one and 5?±-androst-2-en-17-one have been obtained by multistep modification of epiandrosterone â?? intermediate product of transformation of tigogenin. The structures of new hydrazones have been established by IR-, NMR- and mass spectral data. Recent Publications 1.
