  基于大麻二酚的前药：合成和生物评价

  摘要：

  大麻二酚 (CBD 1 ) 是美国 FDA 批准的一种非精神病性大麻素药物，用于治疗难治性癫痫，即 Lennox-Gastaut 和 Dravet 综合征。然而，其低水溶性和口服生物利用度可以通过施用高剂量来补偿，并且对具有改进特性的缀合物的需求不断增加。在这个方向上，目前的工作重点是合成基于 CBD 的前药，以解决溶解度和口服生物利用度差的问题。合成了几种基于 CBD 的前药，并通过一系列测定进行研究：即释放动力学（离体）、溶解度（体外）、化学稳定性（体外）、血浆稳定性（离体）、药代动力学（体内）、和功效研究（体内）。在合成的前药中，基于吗啉基 CBD 的前药3a和3aa显示出良好的释放行为、稳定性、更好的溶解度和血浆曲线。此外，候选前药3aa显示出更好的治疗效果。本研究确定了基于 CBD 的前药具有改善的理化特性和口服暴露。

  Carbonylation of pyrrolidines, catalyzed by cobalt carbonyl, results in the formation of piperidinones. The reaction is regiospecific in most cases, and the yield of product is increased when ruthenium carbonyl is present as a second catalyst. The dual catalytic system [Co 2 (CO) 8 /Ru 3 (CO) 12 ] is useful for the novel rearrangement of heterocyclic nitrogen ketones ((CH 2 ) n NCH 2 COR, n=4-7] to

  para position of phenols favors the formation of α-phenoxy ethyl acetates. The use of EDA to form α-thio ethyl acetates and N-substituted glycine ethyl esters, on the other hand, is hardly affected by the size or structure of the parent thiol or amine, with all of these reactions proceeding in high yield. MTO-catalyzed cycloaddition reactions occur between EDA and aromatic imines, olefins, and carbonyl
