(+)-cis-4,5,7a,8,9,10,11,11a-Octahydro-7H-10-methylindolo[1,7-bc][2,6]- naphthyridine: A 5-HT2C/2B Receptor Antagonist with Low 5-HT2A Receptor Affinity
摘要:
The indolonaphthyridine 8 is described as a selective 5-HT2C/2B vs 5-HT2A receptor antagonist. The compound was synthesized in seven steps starting from indoline and isonicotinic acid chloride. The key step is a photocyclization of the indolinyl tetrahydropyridinocarbamic acid ethyl ester 4 to the cis-octahydroindolo[1,7-bc][2,6]naphthyrdinecarbamic acid ethyl ester 5. The synthesis was accomplished by reduction with aluminum hydride and racemic resolution. The indolonaphthyridine 8 exerted the binding profile of a selective 5-HT2C receptor ligand (pK(D) 7.8) and behaved as an antagonist on the 5-HT-induced accumulation of inositol phosphates in pig choroid plexus cells (pK(B) 7.13). Compound 8 dose-dependently inhibited the ACTH response to MK-212 in rats and the MK-212-induced hypophagic effect with an ID50 value of 0.3 mg/kg sc. Compound 8 acted as a 5-HT2B receptor antagonist at the rat stomach fundus with a pK(B) value of 7.34.

A family of compounds which function as selective ligands for the serotonin receptor 2B (5-HT
2B
) is identified. Some of the compounds are synthetic non-natural ligands which have a relatively strong interaction with 5-HT2B compared to naturally occurring compounds (some of which are identified for the first time herein as ligands for 5-HT
2B
). Because the compounds, both naturally occurring and synthetically produced, function as ligands for 5-HT
2B
they will have application in, for example, the treatment and/or prevention of nervous system disorders such as Alzheimer's disease.

Formulations for and methods of treatment of Dravet syndrome that avoid side effects are disclosed. The formulations comprise a 5-HT receptor agonists which does not agonize selected 5-HT receptor subtypes, and in particular does not agonize the receptor subtype 5-HT2B. Also disclosed are combinations of such 5-HT receptor agonists. Also disclosed are combinations of such 5-HT receptor agonists and SSRIs, SNRIs, and triptans for treating co-morbidities associated with Dravet syndrome.
