Beschreibung
Sarpogrelate hydrochloride, a potent and selective serotonin 5-HT₂ receptor antagonist, was launched in Japan as an antithrombotic. It exhibits inhibition of ex vivo platelet aggregation stimulated by serotonin in combination with collagen and suppression of blood vessel constriction mediated by 5-HT₂ in vitro. Its antithrombotic effects have been demonstrated in several in vivo experimental models including reduction of the mortality rate in acute pulmonary thromboembolic disease, arterial thrombosis, and peripheral obstructive disease. Sarpogrelate has been shown to be especially useful as an antiplatelet agent for patients with Type 2 diabetes mellitus, in whom 5-HT₂mediated amplification of collageninduced platelet aggregation is significantly increased.
Beschreibung
Sarpogrelate is a selective antagonist of the serotonin (5-HT) receptor subtypes 5-HT_2A, 5-HT_2B, and 5-HT_2C (K_is = 3.02, 269, and 37.2 nM, respectively, for human recombinant receptors expressed in CHO-K1 cells). It is selective for 5-HT₂ (K_i = 70.8 nM) over 5-HT₁ (K_i = >26,000 nM), α_1-, α_2-, and β-adrenergic (K_is = 640-123,800 nM), and muscarinic receptors (K_i = >40,000 nM). In vitro, it inhibits aggregation of rat whole blood induced by collagen, 5-HT with collagen, and 5-HT with ADP (; IC₅₀s = 57.7, 0.56, and 22.7 μM, respectively). 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. Sarpogrelate (5 mg/kg per day) decreases ventricular hypertrophy and infarct size in a rat model of myocardial infarction.

Biologische Aktivität
Selective 5-HT 2A receptor antagonist (pK i values are 8.52, 7.43 and 6.57 for 5-HT 2A , 5-HT 2C and 5-HT 2B receptors respectively). Displays selectivity over 5-HT 1 , 5-HT 3 , 5-HT 4 H 1 , H 2 , M 3 , α 1 -adrenergic, α 2 -adrenergic and β -adrenergic receptors. Displays cardioprotective activity in vivo .
in vitro
the major metabolite (r,s)-m-1, and m-1 enantiomers of sarpogrelate specifically blocked 5-ht at 5-ht2a receptors. the stereochemical configuration of the ligands does not obviously play a key role at binding to the 5-ht2a receptor [2].
in vivo
pad patients were divided into two groups. one group treated with 100 mg sarpogrelate in oral 3 times one day for 12 weeks (n = 10), while the other group who remained on conventional therapy as control group (n = 11). forearm blood flow (fbf) and leg blood flow (lbf) responses to reactive hyperemia (rh) and sublingual administration of nitroglycerin (ntg) were measured by strain-gauge plethysmography. after twelve weeks of its administration, fbf and lbf responses during rh exhibited significant increases from 13.2 6 1.7 to 18.1 6 2.2 ml/min every 100 ml tissue (p , 0.01) and from 8.2 6 0.9 to 14.2 6 2.1 ml/min every 100 ml tissue (p , 0.05), respectively. augmentation of fbf and lbf induced by sarpogrelate responses to rh was maintained at 24 weeks. the control group had no change observed in at each follow-up time point. the changes in fbf and lbf after sublingual ntg were similar during follow-up periods in the two groups. these findings suggest that longterm oral administration of sarpogrelate improves vascular function in patients with pad [3].
