1-[3-[3-(4-Chlorophenyl)propoxy]propyl]-piperidinehydrochloride Chemical Properties,Usage,Production
Description
Pitolisant hydrochloride, a first-in-class inverse agonist of the histamine H3 receptor, was approved in the EU for the treatment of excessive daytime sleepiness (EDS) in adults with narcolepsy with or without cataplexy. The drug, which was developed by Bioprojet and has orphan drug designation in the EU and US, enhances wakefulness by increasing histaminergic neuron activity. With once daily oral administration in the morning, patients taking pitolisant exhibited significantly reduced EDS versus placebo but not versus modafinil. Plasma levels of the drug are reduced at the end of the day such that its waking effect is minimized at night (plasma t1/2 10-12 h). Several articles have been published detailing the discovery of pitolisant.
Uses
BF 2649 Hydrochloride, is a novel histamine H3 receptor antagonist and inverse agonist.
Synthesis
The most likely scale preparation of pitolisant hydrochloride
consists of only four synthetic steps starting with the mesylation
of commercial 3-(4-chlorophenyl)propan-1-ol (132). Displacement of the mesylate with the sodium salt of
commercial 3-(piperidin-1-yl)propan-1-ol (133) in warm DMA
assembled the parent drug in 97% yield over two steps. Salt
formation was affected by pH adjustment to 3-4 using HCl gas
in EtOAc. Recrystallization from ethyl acetate and isopropanol
provided pitolisant hydrochloride (XII) on kilogram scale in
78% overall yield across the short four-step protocol.
in vitro
bf2.649 behaved as a competitive antagonist with a ki value of 0.16 nm. bf2.649 functioned as an inverse agonist with an ec50 value of 1.5 nm and an intrinsic activity about 50% higher than that of ciproxifan. pitolisant in vitro potency was approximately 6 times lower at the rodent receptor [1].
in vivo
pitolisant hcl was an oral bioavailable agonist. in mice, after oral and i.v. administrations of pitolisant hcl, the ratio of plasma areas under the curve was 84%. bf2.649 enhanced tele-methylhistamine levels in mouse brain, an index of histaminergic neuron activity in a dose dependent manner with an ed50 value of 1.6 mg/kg p.o. the response persisted after repeated administrations for 17 days [1]. treatment with 20-, 40-, or 60-mg doses of pitolisant showed a statistically significant suppressive effect (standardized photosensitive response [spr] reduction as measured with paired t-tests) in 9/14 (64%) patients of whom 6/14 (43%) showed abolition of the response to intermittent photic stimulation (ips) [3]. bf2.649 showed significant inhibitory activity in several mouse models of schizophrenia [4].
