Receptor agonist activity is not a requirement for muscarinic antinociception

The analgesic effects of a series of muscarinic agonists were investigated by use of the mouse acetic acid writhing, gridshock, hot-plate and tail-flick tests. The compounds tested were oxotremorine, pilocarpine, arecoline, aceclidine, RS86 and four 3-3(substituted-1,2,5-thiadiazol-4-yl)- 1,2,5,6-tetrahydro-1-methyl pyridines (substituted TZTP), these being propoxy-TZTP, 3-Cl-propylthio-TZTP, xanomeline (hexyloxy-TZTP) and hexylthio- TZTP. These agonists were also assayed for their ability to displace [3H]oxotremorine-M and [3H]pirenzepine binding and for their functional selectivity at pharmacologic M1, M2 and M3 receptors. These compounds all produced dose-dependent antinociceptive effects in all of the mouse analgesia tests. The effects of oxotremorine in the writhing test were fully antagonized by the muscarinic antagonist scopolamine (0.1 mg/kg), but only partially antagonized by methscopolamine (10 mg/kg) and unaffected by the opioid antagonist naltrexone. 3-Cl-propylthio-TZTP and propoxy-TZTP had virtually no effect at the M1 receptor subtype as measured by the human m1 clone expressed in baby hamster kidney cells or the rabbit vas deferens assay. These compounds, however, were more potent in the analgesia tests than the selective M1 agonists xanomeline and hexylthio-TZTP. These data suggest that muscarinic analgesia is mediated by central muscarinic receptors. However, activity at the M1 receptor subtype is not a requirement for antinociceptive activity.

The cholinergic system and spatial learning

Acetlylcholine (ACh) in the central nervous system is critical for a multitude of functions. Here, we concentrate on declarative memory in humans, and its equivalent episodic-like memory in rodents and highlight current understanding of cholinergic system in these processes. Spatial memory formation represents a simple form of episodic-like memory in rodents that engages the basal forebrain cholinergic system and its target structures. In these, ACh exerts numerous functions. During spatial acquisition learning, ACh efflux into the extracellular space is immediate in hippocampus and cortex; during consolidation of spatial reference memory, ACh levels are low. These requirements explain why ACh receptor blockade during acquisition blocks memory formation, and it is also consonant with the notion that an unspecific enhancement of cholinergic activity during consolidation is detrimental to memory formation. Working and short-term memory for spatial locations engages the nucleus basalis – prefrontal cortex ACh system. ACh activity is trial related and maintained for some time post-training. Striatal cholinergic activity is increased during stimulus-response learning and behavioural flexibility (reversal learning, extinction) providing a possible switch between different behavioural strategies. At present, there is no clear difference between muscarinic and nicotinergic systems with respect to spatial learning. Antagonists of the respective receptors impair memory formation, agonists can reverse these deficits or may, under specific conditions act more like a general cognitive enhancers by way of improving attention. Data reviewed here do not provide conclusive evidence for muscarinic or nicotinic receptors presenting as novel therapeutic targets, and there is no clear indication for ACh derived novel biomarkers for translational medicine.Unresolved and contradictory results are highlighted and discussed.

Efficacy of glutathione inhibitors for the treatment of ARID1A-deficient diffuse-type gastric cancers

ARID1A, a subunit of the SWI/SNF chromatin remodeling complex, increases the intracellular levels of glutathione (GSH) by upregulating solute carrier family 7 member 11 (SLC7A11). Diffuse-type gastric cancer is an aggressive tumor that is frequently associated with ARID1A deficiency. Here, we investigated the efficacy of GSH inhibition for the treatment of diffuse-type gastric cancer with ARID1A deficiency using ARID1A-proficient or -deficient patient-derived cells (PDCs). ARID1A-deficient PDCs were selectively sensitive to the GSH inhibitor APR-246, the GCLC inhibitor buthionine sulfoximine, and the SLC7A11 inhibitor erastin. Expression of SLC7A11, which is required for incorporation of cystine, and the basal level of GSH were lower in ARID1A-deficient than in ARID1A-proficient PDCs. Treatment with APR-246 decreased intracellular GSH levels, leading to the excessive production of reactive oxygen species (ROS), and these phenotypes are suppressed by supply of cystine and GSH compensators. Taken together, vulnerability of ARID1A-deficient gastric cancer cells to GSH inhibition is caused by decreased GSH synthesis due to diminished SLC7A11 expression. The present results suggest that GSH inhibition is a promising strategy for the treatment of diffuse-type gastric cancers with ARID1A deficiency.

Actionable perturbations of damage responses by TCL1/ATM and epigenetic lesions form the basis of T-PLL

T-cell prolymphocytic leukemia (T-PLL) is a rare and poor-prognostic mature T-cell malignancy. Here we integrated large-scale profiling data of alterations in gene expression, allelic copy number (CN), and nucleotide sequences in 111 well-characterized patients. Besides prominent signatures of T-cell activation and prevalent clonal variants, we also identify novel hot-spots for CN variability, fusion molecules, alternative transcripts, and progression-associated dynamics. The overall lesional spectrum of T-PLL is mainly annotated to axes of DNA damage responses, T-cell receptor/cytokine signaling, and histone modulation. We formulate a multi-dimensional model of T-PLL pathogenesis centered around a unique combination of TCL1 overexpression with damaging ATM aberrations as initiating core lesions. The effects imposed by TCL1 cooperate with compromised ATM toward a leukemogenic phenotype of impaired DNA damage processing. Dysfunctional ATM appears inefficient in alleviating elevated redox burdens and telomere attrition and in evoking a p53-dependent apoptotic response to genotoxic insults. As non-genotoxic strategies, synergistic combinations of p53 reactivators and deacetylase inhibitors reinstate such cell death execution.

Design of alpha7 nicotinic acetylcholine receptor ligands using the (het)Aryl-1,2,3-triazole core: Synthesis, in vitro evaluation and SAR studies

We report here the synthesis of a large library of 1,2,3-triazole derivatives which were in vitro tested as alpha7 nAchR ligands. The SAR study revealed that several crucial factors are involved in the affinity of these compounds for alpha7 nAchR such as a (R) quinuclidine configuration and a mono C-3 quinuclidine substitution. The triazole ring was substituted by a phenyl ring bearing small OMe/CH2F groups or fluorine atom and by several heterocycles such as thiophenes, furanes, benzothiophenes or benzofuranes. Among the 30 derivatives tested, the two derivatives 10 and 39 with Ki in the nanomolar range were identified (2.3 and 3 nM respectively). They exhibited a strict selectivity toward the alpha4beta2 nicotinic receptor (up to 1 muM) but interacted with the 5HT3 receptors with Ki around 3 nM. Synthesis, SAR studies and a full description of the derivatives are reported.

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.
