作为我们放射性药物化学计划的一部分,我们准备并评估了一系列放射性碘化的1-烷基-4-苯基哌嗪作为潜在的脑成像剂。选择这些化合物是基于它们的合成多功能性,向亲电取代的活化作用以及易于纯化。容易获得中间体1-6,并以76-91%的分离的放射化学产率将其转化为相应的放射性碘化产物7-12。在大鼠中的组织分布表明,1-N-丁基衍生物9具有比4-更好的脑摄取(0.28-0.35%ID X kg / g),保留和选择性(脑/血大于20)的最佳组合。 h评估期。

triacetoxyborohydride is presented as a general reducing agent for the reductiveamination of aldehydes and ketones. Procedures for using this mild and selective reagent have been developed for a wide variety of substrates. The scope of the reaction includes aliphatic acyclic and cyclic ketones, aliphatic and aromatic aldehydes, and primary and secondary amines including a variety of weakly basic and

The 5‐HT1a and 5‐HT2 receptoraffinity of a set of 44 N‐alkylated 1‐arylpiperazines and their analogs has been analyzed: the n‐hexyl derivatives were the most potent and the most selective 5‐HT1a ligands of all the investigated N‐alkyl homologues. The alkylchain may stablize the 5‐HT1a receptor‐ligand complex by hydrophobic forces. A set of the alkyl substituent contributions (Cht1a) for prediction
