Lu, Bin; Xu, Minghao; Qi, Xiaotian; Jiang, Min; Xiao, Wen-Jing; Chen, Jia-Rong published the artcile< Switchable Radical Carbonylation by Philicity Regulation>, Application In Synthesis of 84163-77-9, the main research area is amide preparation; ketoamide preparation; aryl amine cyclicbutane oxime ester carbon monoxide carbonylation photocatalyst.

A new strategy that exploits photoredox catalysis to regulate the philicity of amine coupling partners to drive switchable radical carbonylation reactions was described. In double carbonylation, amines e.g., aniline were first transformed into nitrogen radical cations by single-electron transfer-oxidation and coupled with CO to form carbamoyl radicals, which further underwent radical cross-coupling with the incipient cyanoalkyl acyl radicals to afford the double carbonylation products. Upon the addition of stoichiometric 4-dimethylaminopyridine (DMAP), DMAP competitively traps the initially formed cyanoalkyl acyl radical to form the relatively stabilized cyanoalkyl acyl-DMAP salts that engaged in the subsequent substitution with the nucleophilic amines to produce the single carbonylation products. The reaction proceeded smoothly with excellent selectivity in the presence of various amine nucleophiles at room temperature, generating valuable amides e.g., 4-cyano-N-phenylbutanamide and α-ketoamides e.g., 5-cyano-2-oxo-N-phenylpentanamide in a versatile and controlled fashion. Combined exptl. and computational studies provided mechanistic insights into the possible pathways.

Gao, Lanchang; Hao, Chao; Chen, Jiali; Ma, Ru; Zheng, Lu; Wu, Qingkun; Liu, Xin; Liu, Bi-Feng; Zhang, Guisen; Chen, Yin; Jin, Jian published the artcile< Discovery of a new class of multi-target heterocycle piperidine derivatives as potential antipsychotics with pro-cognitive effect>, Electric Literature of 84163-77-9, the main research area is benzoisoxazolyl piperidine synthesis antipsychotic procognitive; Atypical antipsychotics; Cognition; Dopamine; Multi-target; Serotonin.

A series of benzoisoxazolylpiperidine derivatives were synthesized by using the multi-target strategies and their potent affinities for dopamine (DA), serotonin (5-HT) and human histamine H3 receptors have been evaluated. Of these compounds, the promising candidate 4w (I) displayed high affinities for D2, D3, 5-HT1A, 5-HT2A and H3, a moderate affinity for 5-HT6, negligible effects on the human ether-a-go-go-related gene (hERG) channel, low affinities for off-target receptors (5-HT2C, adrenergic α1 and H1). In addition, the animal behavioral study revealed that, compared to risperidone, compound 4w significantly inhibited apomorphine-induced climbing and MK-801-induced movement behaviors with a high threshold for catalepsy and low liabilities for weight gain and hyperprolactinemia. Results from the conditioned avoidance response test and novel object recognition task demonstrated that 4w had pro-cognitive effects. Thus, the antipsychotic drug-like activities of 4w indicate that it may be a potential polypharmacol. antipsychotic candidate drug.

A series of novel aralkyl piperazine and piperidine derivatives were synthesized, and evaluated for their serotonin reuptake inhibitory and 5-HT1A/5-HT7 receptors affinities activity. Antidepressant activities in vivo of the selective compound were screened using the forced swimming test (FST) and tail suspension test (TST). The results indicated that compound 19a (I) exhibited high affinities for the 5-HT1A/5-HT7 receptors (5-HT1A, Ki = 12 nM; 5-HT7, Ki = 3.2 nM) coupled with potent serotonin reuptake inhibition (IC50 = 14 nM) and showed a marked antidepressant-like effect in the FST and TST models.
