  Selective Cytotoxicity of Oxysterols through Structural Modulation on Rings A and B. Synthesis, in Vitro Evaluation, and SAR

  摘要：

  Chemically diverse oxysterols were prepared and evaluated for cytotoxicity, aiming to push forward potency and selectivity. They were tested against seven cancer (HT-29, HepG2, A549, PC3, LAMA-84, MCF-7, and SH-SYSY) and two noncancerous cell lines (ARPE-19 and BJ). The influence of the oxidation pattern on rings A and B was studied. Oxygen functionalities on ring B, such as oxo, oxime, acetamide, acetate, and alkoxy, were evaluated. Most oxysterols were cytotoxic in the low micromolar range, with emphasis to the tetrols 14 and 34, the 6 beta methoxy and acetoxy derivatives 21 and 45, and the oxime 28. In general, the oxysterols were more toxic to cancer cells and a set of compounds (9, 14, 21, 28, 45) with very high selectivity was identified. The cytotoxicity of 3 beta-acetates was lower than that of the parent alcohols, although incubation for a longer period rendered them equally cytotoxic, pointing them as potential prodrugs of oxysterols.

  Syntheses of 5-hydroxy-5α- and 5β-cholestan-6-one (11 and 13) and their 3β-acetoxy (10 and 21) and 3β-benzyloxy derivatives (12 and 19) are described, as are syntheses of the 7α-deutero derivatives of 10 and 21. Related investigations of the syntheses of the 5-methoxy and 5-methyl analogues of these compounds are also discussed. Treatment of 12 with potassium tert-butoxide has been shown to give 5-hydroxy-5β-cholest-3-en-6-one (14) and its Δ² isomer 15. Reaction of 6-nitrocholesteryl acetate (50) with lithium dimethylcuprate gives 3α,5-cyclo-5α-cholestan-6-one (E)-oxime (51) as the major product.
