PROCESS FOR THE PREPARATION OF ENCENICLINE FROM 7-CHLORO-BENZO[B]THIOPHENE-2-CARBOXYLIC ACID CHLORIDE AND (R)-QUINUCLIDIN-3-AMINE IN THE PRESENCE OF IMIDAZOLE

The present invention relates to a process for the preparation of an amide from a carboxylic acid chloride and an organic molecule comprising both a primary amine group and a tertiary amine group, wherein the nitrogen atom of the tertiary amine group is comprised in a non-aromatic heterocycle and wherein the amide bond forms selectively with the primary amine group, comprising the step of reacting the carboxylic acid chloride with an organic molecule comprising both the primary amine group and the tertiary amine group, in the presence of imidazole. This is particularly useful in the preparation of amides from quinuclidin-3-amine, such as for the preparation of encenicline ((R) -7-chloro-N-(quinuclidin-3-yl)benzo[b]thiophene-2-carboxamide) from 7-chloro-benzo[b]thiophene-2-carboxylic acid chloride and (R)- quinuclidin-3-amine in the presence of imidazole. Encenicline is a nicotinic acetylcholine receptor agonist useful as a neuromodulator for the treatment of e.g. cognitive impairment, schizophrenia and Alzheimer’s disease.

Discovery of potent positive allosteric modulators of the alpha3beta2 nicotinic acetylcholine receptor by a chemical space walk in chembl

While a plethora of ligands are known for the well studied alpha7 and alpha4beta2 nicotinic acetylcholine receptor (nAChR), only very few ligands address the related alpha3beta2 nAChR expressed in the central nervous system and at the neuromuscular junction. Starting with the public database ChEMBL organized in the chemical space of Molecular Quantum Numbers (MQN, a series of 42 integer value descriptors of molecular structure), a visual survey of nearest neighbors of the alpha7 nAChR partial agonist N-(3R)-1- azabicyclo[2.2.2]oct-3-yl-4-chlorobenzamide (PNU-282,987) pointed to N-(2-halobenzyl)-3-aminoquinuclidines as possible nAChR modulators. This simple “chemical space walk” was performed using a web-browser available at www.gdb.unibe.ch. Electrophysiological recordings revealed that these ligands represent a new and to date most potent class of positive allosteric modulators (PAMs) of the alpha3beta2 nAChR, which also exert significant effects in vivo. The present discovery highlights the value of surveying chemical space neighbors of known drugs within public databases to uncover new pharmacology.

Fluorescent Agonists of the alpha7 Nicotinic Acetylcholine Receptor Derived from 3-Amino-Quinuclidine

Here, we investigated whether fluorescence labeled small molecule agonists of the alpha7 nicotinic acetylcholine receptor (nAChR) might be identified to enhance receptor studies. Enantiomerically pure 3-amino-quinuclidines appended with fluorophores at the 3-amino group were synthesized and tested by electrophysiology on human alpha7 nAChR in Xenopus oocytes, uncovering (R)-4 and (R)-9 as the first examples of fluorescent alpha7 nAChR agonists. These molecules elegantly incorporate the fluorescent reporter group as part of the pharmacophore itself and provide a new class of tool compounds for the study of these ligand-gated ion channels.

Muscarinic receptor agonists, like dopamine receptor antagonist antipsychotics, inhibit conditioned avoidance response in rats

The purpose of our studies was to determine the effects of muscarinic receptor agonists on conditioned avoidance responding in the rat. Rats were trained to avoid or escape an electric shock delivered to the feet in a discrete trial procedure. The muscarinic receptor agonists pilocarpine and [2-ethyl-8-methyl-2,8-diazaspiro(4.5)decane-1,3-dione] hydrochloride (RS86) and the cholinesterase inhibitor physostigmine all decreased the percentage of avoidance responses at doses that produced less than approximately 30% response failures. Similar results were obtained with the antipsychotic drugs haloperidol, trifluoperazine, chlorpromazine, and clozapine. However, the benzodiazepine anxiolytic diazepam did not decrease avoidance responding up to doses that produced ataxia. On the other hand, oxotremorine and arecoline decreased avoidance responding only by producing response failures, whereas aceclidine produced intermediate changes. The muscarinic receptor antagonists scopolamine, trihexyphenidyl, and benztropine were without effect when administered alone but antagonized the decreases in avoidance responding produced by pilocarpine and RS86. Scopolamine had little effect on the decreases in avoidance responding produced by haloperidol. The newer muscarinic receptor partial agonists or agonist/antagonists [R-(Z)-(+)-alpha- (methoxyimino)-1-azabicyclo[2.2.2]octane-3-acetonitrile] hydrochloride, talsaclidine, milameline, and xanomeline also produced dose-related decreases in avoidance responding. Our results demonstrate that muscarinic receptor agonists can decrease avoidance responding in a manner similar to dopamine- receptor antipsychotic drugs, suggesting that muscarinic receptor agonists may provide an alternative approach to the treatment of psychosis.

Aceclidine effects on outflow facility after ciliary muscle disinsertion

Aceclidine increases outflow facility with little accomodative effect. To determine whether this dissociation resides in the ciliary muscle (CM) or trabecular meshwork (TM), we measured aceclidine effects on perfusion outflow facility in both eyes of 8 rhesus monkeys after unilateral disinsertion of the CM from the TM. Facility in the control eyes increased by ~250% following intravenous pilocarpine and by an additional ~250% following intravenous pilocarpine and by an additional ~250% following intracameral pilocarpine, relative to baseline and uncorrected for washout. In CM-disinserted eyes, the facility response to intravenous and intracameral pilocarpine averaged ~25% of that in contralateral controls. Cytochalasin B, which acts directly on the TM to increase facility but is not additive to maximal pilocarpine doses in normal eyes, had no additional effect beyond that of pilocarpine in control eyes but induced an additional 100% facility increase relative to baseline in CM-disinserted eyes. The accomodative response to carbachol in CM-disinserted eyes was ~80% of that in contralateral controls, consistent with retention of CM contractility and the gonioscopic appearance of shallow CM disinsertion. Intracameral aceclidine HCl doses of 5 and 50 mug increased outflow facility by ~80 and 250%, respectively, in control eyes, and by ~0 and 80% in Cm-disinserted eyes. Either the low aceclidine dose affected facility via the CM, while the high dose exerted an additional effect on the TM, or aceclidine acted only via the CM, with the low dose being ineffective and the high dose modestly effective in CM-disinserted eyes because only a few CM-TM attachments remained.

Metabolomics responses of Bambusa pervariabilis ¡Á Dendrocalamopsis grandis varieties to Biotic (pathogenic fungus) stress

Bambusa pervariabilis ¡Á Dendrocalamopsis grandis blight, caused by Arthrinium phaeospermum, is one of the most common and serious diseases in bamboo and occurs in the newly born twigs. Bamboo has suffered large dead areas, including more than 3000 hm2, which greatly threatens the process of returning farmlands to forests and the construction of ecological barriers. To identify differential metabolites and metabolic pathways associated with B. pervariabilis ¡Á D. grandis to A. phaeospermum, ultra-performance liquid chromatography (UPLC) and quadrupole-time of flight (Q-TOF) Mass Spectrometry (MS) combined with a data-dependent acquisition method was used to analyse the entire sample spectrum. In total, 13223 positive ion peaks and 10616 negative ion peaks were extracted. OPLS-DA and several other analyses were performed using the original data. The OPLS-DA models showed good quality and had strong predictive power, indicating clear trends in the analyses of the treatment and control groups. Clustering and KEGG pathway analyses were used to screen the differential metabolites in the treatment and control groups from the three B. pervariabilis ¡Á D. grandis varieties and reflected their metabolic responses induced by A. phaeospermum infection. The results showed that the three B. pervariabilis ¡Á D. grandis varieties mode showed significant changes in the following six resistance-related metabolites after A. phaeospermum invasion in positive and negative ion modes: proline, glutamine, dictamnine, apigenin 7-O-neohesperidoside, glutamate, and cis-Aconitate. The following four main metabolic pathways are involved: Arginine and proline metabolism, Glyoxylate and dicarboxylate metabolism, Biosynthesis of alkaloids derived from shikimate pathway, and Flavone and flavonol biosynthesis. This study lays a foundation for the later detection of differential metabolites and metabolic pathways for targeting, and provides a theoretical basis for disease-resistant breeding and the control of B. pervariabilis ¡Á D. grandis blight.
