Eur J Med Chem 2023; 261:115855. [PMID: 37847955 DOI: 10.1016/j.ejmech.2023.115855] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Revised: 09/13/2023] [Accepted: 10/04/2023] [Indexed: 10/19/2023]
Abstract
In view of the fact that the G-protein-coupled receptors (GPCRs) sit at the top of the signaling pathways triggering a diverse range of signaling cascades towards a cellular event, GPCRs are regarded as central drug targets. mGlu5, a type of classical GPCRs, is highly expressed in the central nervous system (CNS) and responds to the neurotransmitter glutamate. Researches show that mGlu5 is a potential drug target for the treatment of depression. Up to now, multiple mGlu5 negative allosteric modulators (NAMs) have entered clinical trials, but no small molecule mGlu5 NAM has yet to reach market. Herein, we report the structural optimization and structure-activity relationship studies of a series of novel mGlu5 NAMs. Among them, the novel compound 10b is a high-affinity mGluR5 antagonist, with an IC50 value of 11.5 nM. Besides, we evaluated the anti-depressant effect of compound 10b using the chronic unpredictable mild stress (CUMS)-induced depression model. The data showed that the mice in CUMS group were featured by decreased level of serum 5-HT and increased level of serum CORT, and the expression of synaptic proteins were reduced, including GluA1, GluA2, p-PKA, BDNF and TrkB. However, those factors for identifying sensitivity to depression-like behaviors could be improved by compound 10b treatment. The preliminary toxicology evaluations indicated that compound 10b had a good safety profile in vivo. Collectively, the compound 10b represents a promising lead compound for the treatment of depressive disorder.

Abstract
Gold(III)-catalyzed annulation of electron-deficient alkynes and 2-amino-arylcarbonyls provides general modular one-step access to a broad scope of quinoline products. This highly selective reaction is a useful alternative to the classic Friedländer synthesis, which requires harsh reaction conditions. In contrast, the developed method works under relatively mild PicAuCl2-catalyzed conditions and exhibits a high functional group tolerance (40 examples; yields of ≤96%). Another feature of the developed approach is a versatility toward other electron-deficient alkynes. Alkynylsulfones, alkynylcarbonyls, alkynylphosphonates, propiolonitriles, and trifluoromethylated alkynes can be used as the starting materials for the preparation of quinolines diversely substituted at position 3. On the basis of experimental data, we proposed a reaction mechanism in which gold(III) functions as a strong electrophilic activator of the C≡C bond and the carbonyl group. The synthetic potential of the presented method is additionally illustrated by practical postmodifications of the obtained compounds, including a two-step synthesis of interpirdine, a potent drug candidate.

Abstract
We report herein an efficient synthesis of 3-functionalized 4-quinolones, a class of privileged pharmacophores found in numerous biologically and pharmaceutically active compounds. Our synthetic strategy features a telescoped two-step sequence starting from readily available anthranilic acids and functionalized methane derivatives bearing an electron-withdrawing group, such as methyl sulfones, methyl ketones, and acetonitrile. The method delivers good to excellent yields for a variety of structurally diverse substrates, showing good functional group tolerability. We believe that the disclosed method offers a highly efficient and practical entry to functionalized 4-quinolones under mild conditions that is amenable to preparative-scale synthesis.

Abstract
An easy synthetic route towards ethyl 1-(3-tosylquinolin-4-yl)piperidine-4-carboxylate was found. Its molecular and crystal structures are described as well and the biological activity is also predicted using molecular docking studies. The title compound, C24H26N2O4S, can be obtained via two synthetic routes. According to our investigations, the most suitable way is by the reaction of ethyl 2-bromoacetate with sodium tosylsulfinate in dry DMF. It was crystallized from methanol into the monoclinic P21/n space group with a single molecule in the asymmetric unit. Hirshfeld surface analysis was performed to define the hydrogen bonds and analysis of the two-dimensional fingerprint plots was used to distinguish the different types of interactions. Two very weak non-classical C—H⋯O hydrogen bonds were found and the contributions of short contacts to the Hirshfeld surface were determined. Molecules form an isotropic network of intermolecular interactions according to an analysis of the pairwise interaction energies. A molecular docking study evaluated the interactions in the title compound with the active centers of macromolecules of bacterial targets (Staphylococcus aureus DNA Gyrase PDB ID: 2XCR, Mycobacterium tuberculosis topoisomerase II PDB ID: 5BTL, Streptococcus pneumoniae topoisomerase IV PDB ID: 4KPF) and revealed high affinity towards them that exceeded the reference antibiotics of the fluoroquinolone group.

Abstract
Metabotropic glutamate receptor 5 (mGlu5) plays a key role in synaptic information storage and memory, which is a well-known target for a variety of psychiatric and neurodegenerative disorders. In recent years, the increasing efforts have been focused on the design of allosteric modulators, and the negative allosteric modulators (NAMs) are the front-runners. Recently, the architecture of the transmembrane (TM) domain of mGlu5 receptor has been determined by crystallographic experiment. However, it has been not well understood how the pharmacophores of NAMs accommodated into the allosteric binding site. In this study, molecular dynamics (MD) simulations were performed on mGlu5 receptor bound with NAMs in preclinical or clinical development to shed light on this issue. In order to identify the key residues, the binding free energies as well as per-residue contributions for NAMs binding to mGlu5 receptor were calculated. Subsequently, the in silico site-directed mutagenesis of the key residues was performed to verify the accuracy of simulation models. As a result, the shared common features of the studied 5 clinically important NAMs (mavoglurant, dipraglurant, basimglurant, STX107, and fenobam) interacting with 11 residues in allosteric site were obtained. This comprehensive study presented a better understanding of mGlu5 receptor NAMs binding mechanism, which would be further used as a useful framework to assess and discover novel lead scaffolds for NAMs.
