side chain at position 17 is required for the biological activity of the compounds as we previously confirmed, elimination of the 4,5-double bond augmented the cytotoxicactivity for the steroidal oximes. In addition, the presence of a hydroxy on 3- or 6-position of the steroidal nucleus resulted in a remarkable increase of cytotoxicactivity. Our findings present more evidence showing the relationship
Steroidal thiosemicarbazones, semicarbazones and hydrazones have received extensive attention of scientists recently because they exhibit some biological activities such as antibacterial, antiviral and anticancer. Using different steroids as starting materials, through different chemical methods, 24 steroidal compounds with thiosemicarbazone, semicarbazone or hydrazone groups in their structures, were
