Naronapride (free base), also known as ATI-7505, is a highly selective, high-affinity 5-HT(4) receptor agonist for gastrointestinal motility disorders. ATI-7505 accelerates overall colonic transit and tends to accelerate GE and AC emptying and loosen stool consistency.

 

Investigated for use/treatment in gastroesophageal reflux disease (GERD) and gastroparesis.

Renexxion , presumed to have been spun-out from Armetheon , under license from ARYx Therapeutics is developing naronapride (ATI-7505; phase 2 clinical in February 2020), an analog of the gastroprokinetic 5-HT 4 agonist cisapride identified using ARYx’s RetroMetabolic platform technology (ARM), for the oral treatment of upper GI disorders. In September 2018, this was still the case . PATENT

Process for preparing trihydrate salt of naronapride  hydrochloride as 5-HT 4 receptor agonist useful for treating gastrointestinal disorders such as dyspepsia, gastroparesis, constipation, post-operative ileus. Appears to be the first filing from the assignee and the inventors on this compound,

In some aspects, provided herein is a method of making a trihydrate form of (3S, 4R, 3’R)-6-[4-(4-amino-5-chloro-2-methoxy-benzoylamino)-3-methoxy-piperidin-l-yl]-hexanoic acid l-azabicyclo[2.2.2]oct-3’-yl ester di-hydrochloride salt, which has the following formula:

Example 5: NMR Characterization of the Trihydrate

[0282] ^-Nuclear Magnetic Resonance Spectroscopy (‘H-NMR) : Approximately 6 mg of the trihydrate was dissolved in in 1 g of deuterated solvent (dimethylsulfoxide (DMSO)-C45 99.9% d, with 0.05% v/v tetramethyl silane (TMS)). A Varian Gemini 300 MHz FT-NMR spectrometer was used to obtain the ¾-NMK spectrum. A list of the peaks is provided in Table 1 below. A representative ‘H-NMR spectrum is provided in FIG. 6.

[0283] 13 C-Nuclear Magnetic Resonance Spectroscopy ( 13C-NMR ): Approximately 46 mg of the trihydrate was dissolved in 1 mL of deuterated solvent (deuterium oxide, Aldrich, 99.9% D, TPAS 0.75%). The 13C-NMR spectrum was obtained using a Varian Gemini 300 MHz FT-NMR spectrometer. A list of the peaks is provided in Table 2 below. A representative 13C-NMR spectrum is provided in FIG. 7.
