The main goal was to create two new groups of indole derivatives, hydrazine-1-carbothioamide ( and ) and oxadiazole (, and ) that target EGFR (, , ) or VEGFR-2 (). The new derivatives were characterized using various spectroscopic techniques. Docking studies were used to investigate the binding patterns to EGFR/VEGFR-2, and the anti-proliferative properties were tested . Compounds (targeting EGFR) and (targeting VEGFR-2) were the most effective cytotoxic agents, arresting cancer cells in the G2/M phase and inducing the extrinsic apoptosis pathway. The results of this study show that compounds and are promising cytotoxic compounds that inhibit the tyrosine kinase activity of EGFR and VEGFR-2, respectively.

Background: Heredity and epigenetics affect the pathogenesis of microscopic polyangiitis (MPA). Tyrosine kinase 2 (TYK2) polymorphisms (rs2304256C > A, rs280519A > G, and rs12720270G > A) may be potential protective factors against anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Current research suggests that TYK2 is associated with various autoimmune diseases; however, no study has examined the relationship between TYK2 polymorphisms and AAV.

Secondary hemophagocytic lymphohistiocytosis (HLH) syndrome, a fatal disorder characterized by NK/T-cell deficiency, cytokine storm, and organ damage, is rare in chronic lymphocytic leukemia (CLL). Ibrutinib, the first generation of irreversible Bruton's tyrosine kinase inhibitor, has been the first-line therapy for CLL. As an off-target effect, it can also block IL-2 inducible T-cell kinase (ITK), which is essential in maintaining normal NK and T-cell functions.

Iruplinalkib (WX-0593), a selective oral ALK/ROS1 tyrosine kinase inhibitor, was approved in China as first-line therapy for ALK-positive non-small-cell lung cancer (NSCLC) and for the treatment of locally advanced or metastatic ALK-positive NSCLC that has progressed following crizotinib therapy. Pharmacokinetics (PK) data of iruplinalkib have been collected in healthy subjects and patient populations in several studies. We developed a population PK (PopPK) model for describing iruplinalkib plasma concentrations and for evaluating whether dose adjustments are necessary based on demographic factors or disease characteristics.

The absorption and bioavailability of most tyrosine kinase inhibitors are affected by gastrointestinal pH as they are weak basic lipophilic drugs. Hence, concomitant use of acid reducing agents (ARAs) is frequently restricted. Particularly comedication of crystalline dasatinib (Sprycel) and proton-pump inhibitors (PPIs) should be avoided.

Up to 50% of individuals with uveal melanoma (UM), a frequent cancer of the eye, pass away from metastases. One of the major challenges in treating UM is the role of receptor tyrosine kinases (RTKs), which mediate the epithelial-mesenchymal transition (EMT) of tumors. RTKs are involved in binding multiple growth factors, leading to angiogenesis and vasculogenic mimicry (VM) phenomena.
