—— | bis(17-triflyloxy-Δ16-5α-androstan[2,3-b:2′,3′-e])pyrazine | 1376937-10-8 | C40H50F6N2O6S2 | 832.969 |
Bis-steroid pyrazines fused through rings D of the steroid skeleton were synthesized. Methods for the preparation of the corresponding rings A fused derivatives (cephalostatin type) were checked on simple androstanes and then a symmetrical D fused analogue, 5α-androstano[16'',17''-5',6']pyrazino[2',3'-16,17]-5α-androstane-3β,3''b-diol, was prepared. Partially substituted bis-steroid pyrazines in both series were prepared and their use for the preparation of higher fused compounds was discussed. No significant cytostatic activity was found on parent bis-steroid pyrazines both A and D fused.
