Dihydropyridines are the most extensively used drugs in the treatment of hypertension. Nifedipine is the prototype of calcium channel blocker. The dihydropyridine derivative compounds of diethyl 4-(4-bromophenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate (DHPB), diethyl 4-(furan-2yl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate (DHPF), and diethyl-4-phenyl-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate (DHPP) were synthesized using the Hantzsch reaction. The DFT/B3LYP exchange-correlation function was employed to perform quantum chemical calculations such as molecular geometry optimization, vibrational analysis, frontier molecular orbital (FMO), molecular electrostatic potential (MEP), natural bond order (NBO), global reactive descriptors, and Fukui functions to determine the structural characteristics related to biological activity of the compounds. The molecular docking and molecular dynamics were employed to study the binding interaction and stability of protein-ligand complex in the docked site.

Predicting Carbonic Anhydrase Binding Affinity: Insights from QM Cluster Models.

A systematic series of QM cluster models has been developed to predict the trend in the carbonic anhydrase binding affinity of a structurally diverse dataset of ligands. Reference DLPNO-CCSD(T)/CBS binding energies were generated for a cluster model and used to evaluate the performance of contemporary density functional theory methods, including Grimme's "3c" DFT composite methods (rSCAN-3c and ωB97X-3c). It is demonstrated that when validated QM methods are used, the predictive power of the cluster models improves systematically with the size of the cluster models.

Nanobodies or variable antigen-binding domains (VH) derived from heavy chain-only antibodies (HcAb) occurring in the Camelidae family offer certain superior physicochemical characteristics like enhanced stability, solubility, and low immunogenicity compared to conventional antibodies. Their efficient antigen-binding capabilities make them a preferred choice for next-generation small biologics. In the present work, we design an anti-SARS-CoV-2 bi-paratopic nanobody drug conjugate by screening a nanobody database.

Cystitis glandularis (CG) is a chronic hyperplastic disorder of the bladder, and the available clinical drug therapy is insufficient currently. Glycyrrhetinic acid (GA), a bioactive compound extracted from the roots of Glycyrrhiza glabra, is found with beneficial actions, including anti-inflammatory and anti-oxidative effects. We previously reported that GA relieves CG symptoms in animal model, implying the potential application of GA to treat CG.
