2-Methylbutyrylcarnitine chloride

2-Methylbutyrylcarnitine (chloride) acts as a gut microbial metabolite that targets integrin α2β1 on platelets, facilitating the activation of cytosolic phospholipase A2 (cPLA2) and enhancing platelet hyperresponsiveness. This compound further augments platelet hyperreactivity and promotes thrombus formation in mice. It is also characterized as a branched-chain acylcarnitine.
