, p. 12116 - 12119 (2020)
Herein we describe the development of the first mitochondrial Cl-selective fluorescent probe, Mito-MQAE, and its applications in biological systems. Fluorescence of Mito-MQAE is insensitive to pH over the physiological pH range and is quenched by Cl- with a Stern-Volmer quenching constant of 201 M-1 at pH 7.0. The results of cell studies using Mito-MQAE show that substances with the ability to disrupt mitochondrial membranes cause increases in the mitochondrial Cl- concentration.

HDAC8 has been established as one of the vital targets as far as the cancer is concerned. Different compounds having potential HDAC inhibitory activity have been approved by USFDA. However, none of these compounds are selective towards specific HDAC isoform. In this current study, some new hydroxamate derivatives with alkylpiperidine and alkylpiperazine linker moieties have been designed, synthesized and biologically evaluated. All these compounds are effective HDAC8 inhibitors comprising more or less similar cytotoxic potential against different cancer cell lines. It is observed that the piperazine scaffold containing compound is more active than the compound with piperidine scaffold for exerting HDAC8 inhibitory activity. Moreover, the 4-quinolyl cap group is better than the biphenyl group which is better than the benzyl group for producing higher HDAC8 inhibition as well as cytotoxicity. These compounds displayed selective HDAC8 inhibition over HDAC3. Moreover, these compounds showed an increased caspase3/7 activity suggesting their anticancer potential through modulation of apoptotic pathways. Molecular docking study with three potent compounds was performed with both HDAC3 and HDAC8 enzymes to understand the selectivity profile of these compounds. Compound containing 4-quinolyl cap group with alkyl piperazinyl urea linker moiety has been emerged out as the lead molecule that may be further modified to design more effective and selective HDAC8 inhibitors in future.

Chikungunya virus (CHIKV) is a re-emerging vector-borne alphavirus and is transmitted to humans by Aedes mosquitoes. Despite the re-emergence of CHIKV as an epidemic threat, there is no approved effective antiviral treatment currently available for CHIKV. Herein, we report the synthesis and structure-activity relationship studies of a class of thieno[3,2-b]pyrroles and the discovery of a trisubstituted thieno[3,2-b]pyrrole 5-carboxamide 15c that exhibits potent inhibitory activity against in vitro CHIKV infection. Compound 15c displayed low micromolar activity (EC50 value of ca. 2 μM) and limited cytotoxic liability (CC50 > 100 μM) therefore furnishing a selectivity index of greater than 32. Notably, 15c not only controlled viral RNA production, but efficiently inhibited the expression of CHIKV nsP1, nsP3, capsid, and E2 proteins at a concentration as low as 2.5 μM. More importantly, 15c also demonstrated broad spectrum antiviral activity against other clinically important alphaviruses such as O'nyong-nyong virus and Sindbis virus.

A functional high throughput screen identified a novel chemotype for the positive allosteric modulation (PAM) of the muscarinic acetylcholine receptor (mAChR) subtype 5 (M5). Application of rapid analog, iterative parallel synthesis efficiently optimized M5potency to arrive at the most potent M5PAMs prepared to date and provided tool compound 8n (ML380) demonstrating modest CNS penetration (human M5EC50= 190 nM, rat M5EC50= 610 nM, brain to plasma ratio (Kp) of 0.36).

Based on a putative 'Y shape' pharmacophore model of CCR5 inhibitors, a series of novel piperidine-4-carboxamide derivatives were designed and synthesized using a group-reverse strategy. Among synthesized target compounds, 16g (IC50 = 25.73 nM) and 16i (IC50 = 25.53 nM) showed equivalent inhibitory activity against CCR5 to that of the positive control maraviroc (IC50 = 25.43 nM) in calcium mobilization assay. Selected compounds were further tested for their antiviral activity in HIV-1 single cycle assay. Two compounds, 16g and 16i, displayed antiviral activity with IC 50 values of 73.01 nM and 94.10 nM, respectively. Additionally, the pharmacokinetic properties and inhibitory potency against hERG of 16g were evaluated, providing a foundation for ongoing optimization.

The discovery and Structure-activity relationship (SAR) of a series of allosteric muscarinic M1 receptor agonists are described. Compound 17 (Lu AE51090) was identified as a representative compound from the series, based on its high selectivity as an agonist at the muscarinic M1 receptor across a panel of muscarinic receptor subtypes. Furthermore, 17 displayed a high degree of selectivity when tested in a broad panel of G-protein-coupled receptors, ion channels, transporters, and enzymes, and 17 showed an acceptable pharmacokinetic profile and sufficient brain exposure in rodents in order to characterize the compound in vivo. Hence, in a rodent model of learning and memory, 17 reversed delay-induced natural forgetting, suggesting a procognitive potential of 17.
