FDA-approved drugs as PIM-1 kinase inhibitors: A drug repurposed approach for cancer therapy.

PIM-1 kinase, a member of the Serine/Threonine kinase family, has emerged as a promising therapeutic target in various cancers due to its role in promoting tumor growth and resistance to conventional therapies. In this study, we employed a structure-based approach to screen 3800 FDA-approved drugs to discover potential inhibitors of PIM-1. After an initial selection of 50 candidates based on high docking scores, four drugs, stanozolol, alfaxalone, rifaximin, and telmisartan, were identified as strong PIM-1 binders, interacting with key residues in the ATP-binding pocket of the kinase.

Exploring PDK3 inhibition in lung cancer through drug repurposing for potential therapeutic interventions.

The pyruvate dehydrogenase kinase-3 (PDK3) plays an important role in the regulation of a variety of cancers, including lung, by inhibiting the pyruvate dehydrogenase complex (PDC), shifting energy production towards glycolysis necessary for cancer metabolism. In this study, we aimed to identify potential PDK3 inhibitors using a computer-based drug design approach. Virtual screening of the FDA-approved library of 3839 compounds was carried out, from which Bagrosin and Dehydrocholic acid appeared best due to their strong binding affinity, specific interactions, and potential biological characteristics, and thus were selected for further investigations.

Investigating pH-induced conformational switch in PIM-1: An integrated multi spectroscopic and MD simulation study.

PIM-1 is a Ser/Thr kinase, which has been extensively studied as a potential target for cancer therapy due to its significant roles in various cancers, including prostate and breast cancers. Given its importance in cancer, researchers are investigating the structure of PIM-1 for pharmacological inhibition to discover therapeutic intervention. This study examines structural and conformational changes in PIM-1 across different pH using various spectroscopic and computational techniques.

Role of MTH1 in oxidative stress and therapeutic targeting of cancer.

Cancer cells maintain high levels of reactive oxygen species (ROS) to drive their growth, but ROS can trigger cell death through oxidative stress and DNA damage. To survive enhanced ROS levels, cancer cells activate their antioxidant defenses. One such defense is MTH1, an enzyme that prevents the incorporation of oxidized nucleotides into DNA, thus preventing DNA damage and allowing cancer to proliferate.

Targeting prostate cancer via therapeutic targeting of PIM-1 kinase by Naringenin and Quercetin.

PIM-1 kinase belongs to the Ser/Thr kinases family, an attractive therapeutic target for prostate cancer. Here, we screened about 100 natural substances to find potential PIM-1 inhibitors. Two natural compounds, Naringenin and Quercetin, were finally selected based on their PIM-1 inhibitory potential and binding affinities.

Targeting the Sphingosine Kinase/Sphingosine-1-Phosphate Signaling Axis in Drug Discovery for Cancer Therapy.

Sphingolipid metabolites have emerged as critical players in the regulation of various physiological processes. Ceramide and sphingosine induce cell growth arrest and apoptosis, whereas sphingosine-1-phosphate (S1P) promotes cell proliferation and survival. Here, we present an overview of sphingolipid metabolism and the compartmentalization of various sphingolipid metabolites.

Emerging role of protein kinases in diabetes mellitus: From mechanism to therapy.

Diabetes mellitus has emerged as a severe burden on the medical health system across the globe. Presently, around 422 million people are suffering from diabetes which is speculated to be expanded to about 600 million by 2035. Patients with type 2 diabetes are at increased risk of developing detrimental metabolic and cardiovascular complications.
