Virtual screening-driven discovery of dual 5-HT6/5-HT2A receptor ligands with pro-cognitive properties
摘要:
A virtual screening campaign aimed at finding structurally new compounds active at 5-HT6R provided a set of candidates. Among those, one structure, 4-(5-{[(2-{5-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl}ethyl) amino]methyl}furan-2-yl)phenol (1, 5-HT6R K-i = 91 nM), was selected as a hit for further optimization. As expected, the chemical scaffold of selected compound was significantly different from all the serotonin receptor ligands published to date. Synthetic efforts, supported by molecular modelling, provided 43 compounds representing different substitution patterns. The derivative 42, 4-(5-{[(2-{5-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl}ethyl)amino]methyl}furan-2-yl)phenol (5-HT6R K-j= 25, 5-HT2AR K-i = 32 nM), was selected as a lead and showed a good brain/plasma concentration profile, and it reversed phencyclidine-induced memory impairment. Considering the unique activity profile, the obtained series might be a good starting point for the development of a novel antipsychotic or antidepressant with procognitive properties.

A series of 3‐aryl‐4‐pyrrolyl‐maleimides were designed, synthesized, and evaluated for their glycogensynthase kinase‐3β (GSK‐3β) inhibitory activity. Most compounds exhibited potent activity against GSK‐3β. Among them, compounds 11a, 11c, 11h, 11i, and 11j significantly reduced Aβ‐induced Tau hyperphosphorylation, showing the inhibition of GSK‐3β at the cellular level. Structure–activity relationships

An enantioselective epoxidation of tryptophols followed by an intramolecular epoxide opening reaction was realized by chiral vanadium catalysts derived from C2 symmetric bis-hydroxamic acid (BHA) ligands. 3a-Hydroxyfuroindoline derivatives with up to 89% yield and 90% ee were obtained under mild reaction conditions.

The synthesis and CDK inhibitory properties of a series of indolo[6,7-a]pyrrolo[3,4-c]carbazoles is reported. In addition to their potent CDK activity, the compounds display antiproliferative activity against two human cancer cell lines. These inhibitors also effect strong G1 arrest in these cell lines and inhibit Rb phosphorylation at Ser780 consistent with inhibition of cyclin D1/CDK4.
