In vitro

Sarpogrelate inhibits thrombus formation, lowers platelet aggregation, inhibits both serotonin-induced coronary artery spasm and contraction in porcine model as well as vascular smooth muscle cell proliferation. Sarpogrelate exibit specificity toward 5-HT2 receptors, since it has lack of significant 5-HT1, 5-HT3, 5-HT4, α1-, α2- and β-adrenoreceptor, histamine H1, H2 and muscarinic M3 antagonistic activity[1]. Sarpogrelate specifically inhibited the serotonin-induced cytokine trigger but did not influence platelet-derived growth factor–, endothelin–, or angiotensin II–induced cell proliferation. Sarpogrelate inhibited the serotonin-induced increase in intracellular free ionized calcium concentration, prevented mitogen-activated protein kinase activation, and down-regulated expression of the protooncogenes c-fos and c-jun. Sarpogrelate acted at the G1 phase of the cell cycle[2].

In vivo Sarpogrelate can fully protect albino BALB/c retinas, both structurally and functionally, from light-induced retinopathy[3]. It is used clinically for the treatment of vascular inflammation and atherosclerosis. Sarpogrelate mitigates albuminuria in diabetic nephropathy by hindering glomerular platelet activation. Sarpogrelate ameliorates diabetic nephropathy not only by suppressing macrophage infiltration, but also by anti-inflammatory and anti-fibrotic effects[4].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
