    名称:
    An efficient approach to novel 17-5′-(1′,2′,4′)-oxadiazolyl androstenes via the cyclodehydration of cytotoxic O-steroidacylamidoximes, and an evaluation of their inhibitory action on 17α-hydroxylase/C17,20-lyase
    摘要:
    Novel 17-exo-oxadiazoles in the androst-5-ene series were efficiently synthesized in a two-step sequence via the corresponding O-acylamidoxime intermediates (obtained from steroidal 17-carboxylic acids and amidoximes in the presence of coupling reagent), which then underwent tetrabutylammonium fluoride-induced cyclocondensation under mild reaction conditions. The synthesized compounds were subjected to in vitro pharmacological studies to investigate their inhibitory effect on rat testicular C-17,C-20-lyase and their antiproliferative action on four malignant human adherent cell lines (HeLa, MCF7, A2780 and A431). One of the oxadiazolyl derivatives proved to exert significant enzyme-inhibitory action (IC50 = 0.60 mu M), while some of the isolated O-acylated amidoxime intermediates displayed high cytotoxic activities on all examined cell lines, with IC50 values in the range 0.22-3.94 mu M.

  • Novel Regio- and Stereoselective Synthesis of 6-Substituted Pteridines and Naturally Occurring L-<i>erythro</i>-Biopterin

    Condensation of 2,4,5-triamino-6-butoxypyrimidine with various 2-formyloxiranes followed by oxidation with iodine affords 2-amino-4-butoxy-6-(1-hydroxyalkyl)pteridines regioselectively. Naturally occurring L-erythro-biopterin is synthesized from (1S,2S,3S)-2-formyl-3-(1-hydroxyethyl) oxirane. The reaction proceeds via 5,6-dihydropteridine, and the mechanism is discussed with the help of molecular orbital calculations.
