Nickel-catalyzed electrochemical Minisci acylation of aromatic N-heterocycles with alpha-keto acids via ligand-to-metal electron transfer pathway

A nickel-catalyzed electrochemical methodology for the Minisci acylation of aromatic electron-deficient heterocycles with alpha-keto acids has been developed. The reaction is performed in an undivided cell under constant current conditions, featuring broad scope of substrates and avoiding the conventional utilization of silver-based catalysts in conjunction with excess amount of oxidants. Cyclic voltammetric analysis disclosed that a ligand-to-metal electron transfer process may be involved in the generation of the key acyl radicals.

Design, synthesis, and preliminary in vitro and in vivo pharmacological evaluation of 4-{4-[2-(4-(2-substitutedquinoxalin-3-yl)piperazin-1-yl)ethyl] phenyl}thiazoles as atypical antipsychotic agents

A series of 4-{4-[2-(4-(2-substitutedquinoxalin-3-yl)piperazin-1-yl)ethyl] phenyl} thiazoles were synthesized in an effort to prepare novel atypical antipsychotic agents. The compounds were designed, synthesized, and characterized by spectral data (IR, 1H NMR, and MS) and the purity was ascertained by microanalysis. The D2 and 5-HT2A affinity of the synthesized compounds was screened in vitro by radioligand displacement assays on membrane homogenates isolated from rat striatum and rat cortex, respectively. Furthermore, all the synthesized final compounds (10a-g; 11a-g; 12a-g) were screened for their in vivo pharmacological activity in Swiss albino mice. D2 antagonism studies were performed using climbing mouse assay model and 5-HT2A antagonism studies were performed using quipazine-induced head twitches in mice. It was observed that none of the new chemical entities exhibited catalepsy and 12d, 11f, and 10a were found to be the most active compounds with 5-HT2A/D2 ratio of 1.23077, 1.14286, and 1.12857, respectively, while the standard drug risperidone exhibited 5-HT2A/D2 ratio of 1.0989. Among the twenty one new chemical entities, three compounds (12d, 11f, and 10a) were found to exhibit better atypical antipsychotic activity as they were found to have higher Meltzer index than the standard drug risperidone.
