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.

IDrugs and idevices discovery research: Preclinical assays, techniques, and animal model studies for ocular hypotensives and neuroprotectants

Discovery ophthalmic research is centered around delineating the molecular and cellular basis of ocular diseases and finding and exploiting molecular and genetic pathways associated with them. From such studies it is possible to determine suitable intervention points to address the disease process and hopefully to discover therapeutics to treat them. An investigational new drug (IND) filing for a new small-molecule drug, peptide, antibody, genetic treatment, or a device with global health authorities requires a number of preclinical studies to provide necessary safety and efficacy data. Specific regulatory elements needed for such IND-enabling studies are beyond the scope of this article. However, to enhance the overall data packages for such entities and permit high-quality foundation-building publications for medical affairs, additional research and development studies are always desirable. This review aims to provide examples of some target localization/verification, ocular drug discovery processes, and mechanistic and portfolio-enhancing exploratory investigations for candidate drugs and devices for the treatment of ocular hypertension and glaucomatous optic neuropathy (neurodegeneration of retinal ganglion cells and their axons). Examples of compound screening assays, use of various technologies and techniques, deployment of animal models, and data obtained from such studies are also presented.

Mechanism of vascular relaxation by cholinomimetic drugs with special reference to pilocarpine and arecoline

The muscarinic receptor-mediated and non-muscarinic vascular effects of cholinomimetic drugs used in glaucoma were quantified. On the isolated rat aorta, the vascular tone induced by phenylephrine is functionally antagonized by cholinomimetic drugs. Based on EC50, the relative order of potency for the endothelium-dependent vascular relaxation was acetylcholine (0.05 muM) 1 > (¡À)-methacholine (0.35 muM) 1/7 > carbachol (0.63 muM) 1/12 > (¡À)-aceclidine (1.26 muM) 1/25. The maximal effects of the four agonists varied between 82-87%. The muscarinic vascular relaxation of 0.03 muM to 100 muM pilocarpine was less than 15%. At high concentrations, pilocarpine had 1/20,000 the vascular activity of acetylcholine. Physostigmine failed to potentiate the vascular relaxation of exogenous acetylcholine, indicating the absence of acetylcholine esterase in the tissue. Arecoline, with an EC50 of 7.76 muM, was partly sensitive to the removal of the endothelium. Atropine treatment did not block the vascular effect of high concentrations of pilocarpine. Atropine, as expected, blocked the vascular effects of carbachol with KB = 3.2 nM. Pilocarpine produces vascular relaxation by its competition with spasmogens like phenylephrine, oxymetazoline, vasopressin or latanoprost. Arecoline also shares these properties with pilocarpine in the blood vessel. The molecular mechanism of the vascular effects as well as ocular clinical implications of cholinomimetic drugs is discussed.

High-throughput luminescent reporter of insulin secretion for discovering regulators of pancreatic Beta-cell function

Defects in insulin secretion play a central role in the pathogenesis of type 2 diabetes, yet the mechanisms driving beta-cell dysfunction remain poorly understood, and therapies to preserve glucose-dependent insulin release are inadequate. We report a luminescent insulin secretion assay that enables large-scale investigations of beta-cell function, created by inserting Gaussia luciferase into the C-peptide portion of proinsulin. Beta-cell lines expressing this construct cosecrete luciferase and insulin in close correlation, under both standard conditions or when stressed by cytokines, fatty acids, or ER toxins. We adapted the reporter for high-throughput assays and performed a 1,600-compound pilot screen, which identified several classes of drugs inhibiting secretion, as well as glucose-potentiated secretagogues that were confirmed to have activity in primary human islets. Requiring 40-fold less time and expense than the traditional ELISA, this assay may accelerate the identification of pathways governing insulin secretion and compounds that safely augment beta-cell function in diabetes.
