YM443; YM-443; YM 443; Z338; Z-338; Z 338; Acotiamide; Acotiamide hydrochloride trihydrate; Brand name: Acofide.

A peripheral acetylcholinesterase (AChE) inhibitor used to treat functional dyspepsia.

Acotiamide (YM-443, Z-338) is a drug approved in Japan for the treatment of postprandial fullness, upper abdominal bloating, and early satiation due to functional dyspepsia.[1] It acts as an acetylcholinesterase inhibitor.

Acotiamide hydrochloride (acotiamide; N-[2-[bis(1-methylethyl) amino]ethyl]-2-[(2-hydroxy-4,5-dimethoxybenzoyl) amino] thiazole-4-carboxamide monohydrochloride trihydrate, Z-338) has been reported to improve meal-related symptoms of functional dyspepsia in clinical studies.

Acotiamide (Acofide(®)), an oral first-in-class prokinetic drug, is under global development by Zeria Pharmaceutical Co. Ltd and Astellas Pharma Inc. for the treatment of patients with functional dyspepsia. The drug modulates upper gastrointestinal motility to alleviate abdominal symptoms resulting from hypomotility and delayed gastric emptying. It exerts its activity in the stomach via muscarinic receptor inhibition, resulting in enhanced acetylcholine release and inhibition of acetylcholinesterase activity. Unlike other prokinetic drugs that are utilized in the management of functional dyspepsia, acotiamide shows little/no affinity for serotonin or dopamine D2 receptors. Acotiamide is the world’s first approved treatment for functional dyspepsia diagnosed by Rome III criteria, with its first approval occurring in Japan. Phase III trials in this patient population are in preparation in Europe, with phase II trials completed in the USA and Europe.

SYNTHESIS

 

 

EP 0870765; US 5981557; WO 9636619

Acylation of 2-aminothiazole-4-carboxylic acid ethyl ester (I) with 2,4,5-trimethoxybenzoyl chloride (II) produced the corresponding amide (III). The 2-methoxy group of (III) was then selectively cleaved by treatment with pyridine hydrochloride, yielding the 2-hydroxybenzamide (IV). Finally, displacement of the ethyl ester group of (IV) by N,N-diisopropyl ethanediamine (V) upon heating at 120 C furnished the target compound, which was isolated as the corresponding hydrochloride salt.

 

 

EP 0994108; WO 9858918

In a closely related procedure, acid chloride (II), prepared by treatment of 2,4,5-trimethoxybenzoic acid (VI) with SOCl2 in hot toluene, was condensed with aminothiazole (I), yielding amide (III). Displacement of the ethyl ester group of (III) by N,N-diisopropyl ethanediamine (V) furnished diamide (VII). Finally, upon formation of the hydrochloride salt of (VII) in isopropanol, the 2-methoxy group was simultaneously cleaved, directly leading to the title compound.

  A test for the amine hydrochloride Japan Zeria Pharmaceutical Company and Astellas jointly developed acetylcholinesterase inhibitor class of prokinetic drugs, namely the treatment of functional dyspepsia drugs, is the world’s first approved specifically for the treatment of FD drugs, in June 2013 for the first time launched in Japan, under the trade name Acofide. Functional dyspepsia (Functional dyspepsia, FD) is a group of common symptoms include bloating, early satiety, burning sensation, belching, nausea, vomiting and abdominal discomfort and so difficult to describe, and no exact organic disease. Organic diseases because of lack of basic, functional dyspepsia harm to patients focus on the performance of gastrointestinal symptoms caused discomfort and possible impact on the quality of life in. Because some patients with functional dyspepsia symptoms caused by eating less, digestion and absorption efficiency is reduced, resulting in varying degrees of malnutrition (including nutrients are not full). With the people’s demands and improve the quality of life for functional dyspepsia know, the number of visits of the disease gradually increased, to become one of the most common disease of Gastroenterology partner waiting group. Such a high prevalence of functional dyspepsia treatment provides a huge market.

  The present synthesis method has been reported in less divided into four methods are described below:

  1, reference CN1084739C, synthetic route as shown below. Disadvantage of this patent is that: (I) using thionyl chloride and dichloroethane toxic, environmentally damaging substances; (2) demethylation low yield (64.6% to 86 reported in the literature %). Examples reported in this patent first and second step total yield was 84.6% and the total yield of the third-step reaction and recrystallization of 61%, the total yield of 51.6%.

  The method, reported in the patent CN1063442C preparation A (page 25) reports (without reference to examples I and 6, referring to its general method). Patent CN102030654B (page 3) above: Step demethylation reaction generates a lot of by-products, it is difficult to take off only a selective protection of hydroxy groups, poor selectivity. Specific synthetic examples are shown below:

Figure CN103709191AD00052

  Preparation Method B 3 mentioned patent CN1063442C (prepared unprotected, p. 25), where the yield is very low two-step reaction. A test method for the preparation of amines referenced above example (Example 38) A test for specific preparation yield amine not mentioned in the text, but if you use the above method starting materials primary amino side reactions occur.

Abstract

Abstract Image

A three-step synthesis of acotiamide is described. The agent is marketed in Japan for treatment of patients with functional dyspepsia. We designed a one-pot method to prepare the key intermediate 5a from 2 via an acyl chloride and amide and then reacted with 6 to obtain 1 under solvent-free condition. With the use of DCC, the unavoidable impurity 5b was also successfully converted into the desired 1. After isolation of 1, we carried forward to the next step of HCl salt formation, which was proved to be a very effective procedure for the removal of practically all major impurities. The process is cost-effective, simple to operate, and easy to scale-up.

Approval in Japan for Treating Functional Dyspepsia with Acofide®

Press Release


Tokyo, March 25, 2013
– Zeria Pharmaceutical Co., Ltd. (Tokyo: 4559; “Zeria”) and Astellas Pharma Inc. (Tokyo: 4503; “Astellas”) announced today that as of March 25, Zeria has obtained the marketing approval of Acofide® Tablets 100mg (nonproprietary name: acotiamide hydrochloride hydrate; “Acofide”; Zeria’sdevelopment code: “Z-338”; Astellas’s development code: “YM443”) for the treatment of functional dyspepsia(FD) from the Ministry of Health, Labour and Welfare in Japan. Acofide has been co-developed by both companies.

Acotiamide hydrochloride hydrate is a new chemical entity originated by Zeria, and inhibits peripheralacetylcholinesterase activities. Acetylcholine is an important neurotransmitter to regulate gastrointestinalmotility, and through the inhibition of degradation of acetylcholine, Acofide improves the impaired gastricmotility and delayed gastric emptying, and consequently the subjective symptoms of FD such as postprandialfullness, upper abdominal bloating, and early satiation.

Acofide, the world first FD treatment which demonstrated efficacy in the patients with FD diagnosed by the Rome III, will be launched in Japan ahead of the rest of the world.Also, since Acofide will be the first treatment with FD indication, Zeria and Astellas will co-promote Acofide for the sake of the increase of disease awareness of FD, the prompt market penetration, and the maximization of product potential.

In March 2008, Zeria and Astellas concluded the agreement for the co-development and co-marketing of Acofide and, subsequently conducted the co-development. In September 2010, Zeria submitted the application for marketing approval to the Ministry of Health, Labour and Welfare in Japan.

We believe that Acofide will contribute to alleviate the subjective symptoms and improve QOL of patients with FD.

Summary of Approval

Product name: Acofide® Tablets 100mg

Nonproprietary name: Acotiamide hydrochloride hydrate

Formulation: Tablet

Indication: Postprandial fullness, upper abdominal bloating, and early satiation due to functional dyspepsia

Dosage regimen: Normally in adults, 100mg of acotiamide hydrochloride hydrate is taken orally three times per day before a meal.

About Functional Dyspepsia (FD)

According to the Rome III, FD is a gastrointestinal disease comprised of subjective symptoms including postprandial fullness, early satiation and epigastric pain without any organic abnormality on gastrointestinal tract. The etiology of FD is still unclear, but it has been shown that delayed gastric emptying is closely associated with FD.
