An internal standard for the quantification of sarpogrelate
Sarpogrelate-d3 is intended for use as an internal standard for the quantification of sarpogrelate (hydrochloride) by GC- or LC-MS. Sarpogrelate is a selective antagonist of the serotonin (5-HT) receptor subtypes 5-HT2A, 5-HT2B, and 5-HT2C (Kis = 3.02, 269, and 37.2 nM, respectively, for human recombinant receptors expressed in CHO-K1 cells).1 It is selective for 5-HT2 (Ki = 70.8 nM) over 5-HT1 (Ki = >26,000 nM), α1-, α2-, and β-adrenergic (Kis = 640-123,800 nM), and muscarinic receptors (Ki = >40,000 nM).2 In vitro, it inhibits aggregation of rat whole blood induced by collagen, 5-HT with collagen, and 5-HT with ADP .3 In vivo, it inhibits leukocyte-endothelial interactions in the femoral artery induced by a high-fat high-fructose diet (HFFD) in mice when administered at a dose of 5 mg/kg per day.4 Sarpogrelate (5 mg/kg per day) decreases ventricular hypertrophy and infarct size in a rat model of myocardial infarction.5
