Popis: | Recently we reported the synhesis and biological activity of some 5α-androstane derivatives that exhibit pronounced antitumor activity toward certain cancer cell lines [1]. In continuation of the search for highly effective compounds in this series, we synthesized new 5α-androstane and 5α-pregnane derivatives and studied their antitumor activity. Oximes (1-4) were prepared from the corresponding ketosteroids 3α-hydroxy-5α-pregn-16-en-20-one (5), 3α-hydroxy-5α-pregnan-20-one (6), 3α-hydroxy-5α-androst-9(11)-en-17-one (7), and androst-1,4-dien-3,17-dione (8) by reacting them with hydroxylamine in pyridine. The starting ketones (5-8) were synthesized beforehand by the literature method [2]. Aminonitrile 9 was synthesized as previously described [3]. |
