Abstract Interleukin‐23 (IL‐23) is a dominant cytokine in psoriasis, chronic inflammatory skin disease that severely diminishes patients' quality of life and reduces lifespan by up to 10 years. Despite therapeutic advancements, psoriasis remains clinical challenge due the absence definitive cure, treatment side effects, substantial economic burden. Notably, no small molecule inhibitors (SMIs) directly targeting IL‐23 have been developed date, leaving critical gap current therapies. In this...

Cancer remains a critical global health challenge, necessitating advanced drug delivery systems through innovations in materials science and nanotechnology. This study evaluates Gadolinium Metal‐Organic Frameworks (Gd‐MOFs) as potential for anticancer therapy, particularly when combined with radiotherapy. Gd‐MOFs were synthesized using terephthalic acid gadolinium (III) chloride hexahydrate, then loaded methotrexate (MTX). Characterization via FTIR, TGA, DSC, MRI, XRD confirmed their correct...

This study delves into impact synthetic lethality within cancer research, specifically examining interplay between Focal Adhesion Kinase (FAK) and Neurofibromin 2 (NF2) genes. While deactivating FAK NF2 individually has minimal impact, their combined highlights significance lethal interaction. Hence, principal...

PARP-1 (poly(ADP-ribose)-polymerase 1) inhibitors are vital in synthetic lethality, primarily due to their specificity for over PARP-2 (PARP-1 > PARP-2). This is crucial as it allows precise inhibition of tumor cells with Breast Cancer 1 protein (BRCA1) or BRCA2 deficiencies. The development highly specific not only meets the therapeutic needs treatment but also has potential minimize adverse effects associated nonselective inhibition. In this study, a series novel...
