    Topobexin

    		Topoisomerase Cardiovascular Disease
    Topobexin is a TOP2B-selective inhibitor with IC50 values of 0.19 μM and 4.8 μM for TOP2B and TOP2A (DNA decatenation assay). Topobexin binds to non-homologous residues in the obex pocket and targets the ATPase domain of TOP2B. Topobexin prevents anthracycline-induced DNA double-strand break formation, apoptotic signaling mediated by caspase 3/7, 8 and 9, cardiomyocyte morphological changes, mitochondrial depolarization/loss, left ventricular systolic dysfunction, extracellular matrix remodeling, fibrotic alterations, and increases in plasma cardiac troponin T and BNP. Topobexin does not impair the antiproliferative effects of anthracyclines in cancer cells, exhibits no intrinsic cytotoxicity in cardiomyocytes, and is well tolerated in rabbits. Topobexin can be used in studies related to anthracycline-induced cardiotoxicity .

    1-Palmityl-2-O-acetyl-3-glyceryl phosphorylcholine

    (Rac)-PAF (C16)

    		 Endogenous Metabolite Platelet-activating Factor Receptor (PAFR) Inflammation/Immunology
    1-Palmityl-2-O-acetyl-3-glyceryl phosphorylcholine ((Rac)-PAF (C16)) is an endogenous inflammatory lipid mediator. 1-Palmityl-2-O-acetyl-3-glyceryl phosphorylcholine acts as a high-affinity agonist for PAFR (GPCR), inducing platelet aggregation, vascular permeability, and leukocyte chemotaxis at extremely low concentrations. 1-Palmityl-2-O-acetyl-3-glyceryl phosphorylcholine exerts its effects via cell surface receptors to regulate inflammation .
