In this study, we describe our effort to identify a compound, phenylacetamide-1H-imidazol-5-one (KIM-161), from our in-house oncogenic kinase-targeting inhibitors. KIM-161 showed excellent anti-proliferative activities at sub-nanomolar concentrations, primarily against mutant PI3Kα breast cancer cell lines, when compared with wild-type PI3Kα breast cancer cell lines, producing both dose- and time-dependent effects with an IC50 range of 1.42 - 0.064 µM. Next, we observed that KIM-161 was able to induce ROS production by modulating breast cancer metabolism, suggesting its broad effects on mutant PI3Kα regulated downstream pathways. We also computationally analyzed the binding interactions between KIM-161 and PI3K-alpha (PDB ID: 8EXL). Molecular docking showed that KIM-161 had a docking score of -7.44 Kcal/mol, compared to the reference compound, which had a docking score of -7.67 Kcal/mol. Moreover, molecular dynamics simulation studies demonstrated that the PI3Ka-KIM-161 complex remained stable throughout the 100 ns simulation, when compared to the PI3Ka complex with the co-crystallized inhibitor.

Bruton's Tyrosine Kinase (BTK) is crucial for B-cell development, and BTK inhibitors have proven effective in treating B-cell malignancies like Chronic Lymphocytic Leukemia (CLL). Non-covalent inhibitors offer a promising therapeutic approach by avoiding covalent bond formation with the protein. However, therapeutic resistance due to BTK mutations in the catalytic domain has led to relapses and refractory cases in CLL, highlighting the need for a deeper understanding of these mutations' impact on treatment outcomes. This study investigates the effects of four prevalent single-point mutations-A428D, T474I, C481S, and L528W-within the catalytic domain of BTK. Using 12.5 microseconds of molecular dynamics simulations and computational drug discovery methods, we examine how these mutations influence the binding affinities and interactions of non-covalent BTK inhibitors. Molecular Mechanics-Poisson-Boltzmann Surface Area (MM-PBSA) analysis showed that mutant forms of BTK significantly decreased ligand binding free energies compared to the wild types, with a few exceptions. With pocket volume and solvent-accessible surface area analysis, we also show that mutations reduce the binding pocket volume, forcing the inhibitors to move out of the pocket, disrupting the critical non-covalent interactions of the inhibitors with mutant BTK. This confirms the experimental and clinical observations of why these BTK mutations impair inhibitor efficacy fostering drug resistance.

There is currently no published data reporting on the specific interactions between PSGL-1 and Vpu, and possible outcomes and consequences of these interactions. To date, it has only been established that Vpu binds human PSGL-1 to degrade PSGL-1 and therefore promote HIV replication. There are, however, four different types of HIV-1, and it would be helpful to know how VpuM, VpuN, VpuO, and VpuP can bind to and possibly inhibit PSGL-1 expression. Bioinformatics methods were used to find out how strongly each type of Vpu found in the different HIV-1 groups bonds with human PSGL-1. Thus, we used molecular docking (MD) and molecular dynamics simulations (MDS) to figure out how PSGL-1 and VpuM, VpuN, VpuO, and VpuP interact with each other. To ensure the reliability of the predicted outcomes, the binding energy of each model was calculated using the MM/GBSA technique. Our findings show that PSGL-1-VpuP (4 H bonds, 2 salt bridges) and PSGL-1-VpuM (3 H bonds, 2 salt bridges) have stronger bonding affinities than PSGL-1-VpuN (4 H bonds, no salt bridges) and PSGL-1-VpuO (2 H bonds, 1 salt bridge). The MDS test also shows that PSGL-1-VpuM and PSGL-1-VpuP protein complexes are more stable and compact, with lower residual fluctuations compared to PSGL-1-VpuN and PSGL-1-VpuO protein complexes.
