This has eventually and consistently given rise to antimicrobial resistance divulging a need to mitigate infectious outbreaks. Herein, we employed a computational density functional theory (DFT) method at ωB97XD/6-311++g(d, p) level of theory to evaluate the performance of the thiophene derivative 5-(4-bromo-5-(methylthio)thiophen-2-yl)-4-phenyl-4H-1,2,4-triazole-3-thiol 4, which is experimentally synthesized into five compounds (4a, 4b, 4c, 4d, and 4e). The chemical reactivity, kinetic stability, nature of interactions and functional characteristics of the thiophene derivatives were ascertained. The resistance gene PDB ID: 1K25, 2D45, 4UOT, and 7K2X were employed and docked with thiophene derivatives. Interestingly, molecular docking analysis demonstrated that ligands 4a, 4b, 4c, 4d, and 4e are more effective against proteins 1K25, 4U0T and 7K2X than amoxicillin and methicillin. Upon docking with the 2D45 protein, compounds 4c and 4e (- 5.9 kcal/mol) exhibited potential similar to that of methicillin (- 5.9 kcal/mol), while 4a and 4b showed slightly better affinities (- 6.1 kcal/mol and 6.0 kcal/mol). Using Lipinski's Rule of Five (Ghose filter, Veber rules, Muegge filter, and Egan's rule), 4d and 4e were determined to be the most promising candidates for drug development due to their compliance with all evaluated criteria, indicating favourable properties for oral bioavailability and drug likeness.

ER-<i>α</i> is the major ER subtype in the mammary epithelium and plays a critical role in breast cancer progression. Tamoxifen (1-[4-(2-dimethylaminoethoxy)-phenyl]-1,2- diphenylbut-1(Z)-ene) is a nonsteroidal antiestrogen prodrug which formed pharmacologically active metabolite, 4-hydroxytamoxifen, largely used for endocrine therapy in pre and postmenopausal women with ER-positive breast cancer. However, long term treatment with tamoxifen results in acquires resistance and high probability of disease recurring, hence the need for an alternative breast cancer drug. In silico approach was used to investigate the inhibitory activities of a novel dimeric flavanonol OC251FR2 (3,3'-oxybis(5,7-dihydroxy-2-(4-hydroxyphenyl)chroman-4-one)-3,3'-oxybis(5,7-dihydroxy-2-(4-hydroxyphenyl)chroman-4-one) isolated from the chloroform fraction of <i>Garcinia kola</i>, against alpha Estrogen receptor (ER-α); a major contributor to the growth of breast cancer. The docking was conducted using Maestro module 13.5 to obtained the ER-α PDB (5W9C) from NCBI. The OC251FR2 was docked using ligprep module with 4-hydroxytamoxifen being the reference drug. The qikpro was used to investigate the drug-likeliness while ligand docking and induced fit docking were used to investigate the interaction and binding affinity of the ligands with the active sites of the PDB. The result shows that the isolated OC251FR2 with docking score value of -6.214 interact more with amino acids in the active sites via H-bond, pi-pi interaction than the reference drug 4-Hydroxytamoxifen with a docking score value of -5.289. The drug-likeliness determined by qikpro shows that OC251FR2 violated three of the Lipinski rules of 5, and also have percent oral absorption. The quantum mechanics values show that OC251FR2 have similar properties comparable to the reference drug 4-hydroxytamoxifen.

For the fruit infusion, a significant reduction in cell viability was observed specifically at the 800 μg/mL concentration. Fluorescence microscopy and mitochondrial membrane potential results indicated that the leaf infusion was more effective in reducing cell viability and mitochondrial function in SK-MEL-28 cells, possibly due to its greater variety of phenolic compounds compared to the fruit infusion. The leaf infusion also induced higher production of intracellular reactive oxygen species compared to the fruit infusion. Protein sulfhydryl levels were reduced for the leaf infusion. Epigallocatechin gallate, Isoquercitrin, Rutin, Kaempferol-3-O-rutinoside, Chlorogenic acid, and Ellagic acid were identified as the main compounds with activity against SK-MEL-28 cells.

Current treatments target these enzymes individually and often cause significant side effects, highlighting the need for safer alternatives.

This study therefore aims to explore the antibacterial potential of <i>1</i>,<i>2</i>-dibenzoylhydrazine (DBH) as a scaffold against <i>S. aureus</i> drug target enzymes, using integrated computational approaches. The study utilized molecular docking, lead optimization, and structure-based virtual screening techniques to evaluate the binding affinities of DBH and its derivatives against various <i>S. aureus</i> enzymes. Prime/MM-GBSA calculations were performed to validate the binding affinities obtained, and molecular dynamics (MD) simulations were conducted to assess the stability of the DBHs-enzyme complexes. Results indicated that, out of twenty enzymes from <i>S. aureus</i> examined against DBH, carotenoid dehydrosqualene synthase was predicted as a suitable target enzyme for DBH, showing a binding affinity of -8.027 kcal/mol. A lead optimization operation of the compound generated 27 DBH derivatives out of which four exhibited enhanced binding affinities compared to both DBH and a standard antibiotic, ofloxacin. The QSAR model predicted that, DBH and molecule_D_1 have higher PIC₅₀ of 4.779 µM compared with the standard drug (ofloxacin = 4.678 µM). MD simulations confirmed the stability of the top-scoring derivatives within the enzyme's binding pocket, with RMSD and RMSF analyses supporting their potential as inhibitors of the enzyme.
