Sarpogrelate is a selective serotonin 5-HT2A-receptor antagonist used to treat patients with peripheral arterial disease. This drug is rapidly hydrolyzed to its main metabolite (R,S)-1-[2-[2-(3-methoxyphenyl)ethyl]phenoxy]-3- (dimethylamino)-2-propanol (M-1), which is mainly excreted as a glucuronide conjugate. Sarpogrelate was also directly glucuronidated to an O-Acyl glucuronide and a Nglucuronide by UDP-glucuronosyltransferases (UGTs) in human liver microsomes (HLMs). Since M-1 is pharmacologically more active than sarpogrelate, we examined glucuronidation of this metabolite in HLMs and characterized the UGTs responsible for M-1 glucuronidation. Diastereomers of O-glucuronide (SMG1 and SMG3) and a N-glucuronide (SMG2) were identified by incubation of M-1 with HLMs in the presence of uridine 59-diphosphoglucuronic acid (UDPGA), and their structures were confirmed by nuclear magnetic resonance and mass spectrometry analyses. Two O-glucuronides were identified as chiral isomers: SMG1 as R-isomer and SMG3 as S-isomer. Using recombinant UGT enzymes, we determined that SMG1 and SMG3 were predominantly catalyzed by UGT1A9 and UGT2B4, respectively, whereas SMG2 was generated by UGT1A4. In addition, significant correlations were noted between the SMG1 formation rate and propofol glucuronidation (a marker reaction of UGT1A9; r = 0.6269, P a marker reaction of UGT1A4; r = 0.6623, P a panel of HLMs. Inhibition of SMG1, SMG2, and SMG3 formation by niflumic acid, hecogenin, and fluconazole further substantiated the involvement of UGT1A9, UGT1A4, and UGT2B4, respectively. These findings collectively indicate that UGT1A4, UGT1A9, and UGT2B4 are the major UGT isoforms responsible for glucuronidation of M-1, an active metabolite of sarpogrelate. Copyright

A series of ethyl>benzene derivatives were synthesized and evaluated for their ability to inhibit collagen-induced platelet aggregation in vitro and to protect experimantal thrombosis in mice.The results showed that the compounds were in vitro inhibitors of collagen-induced platelet aggregation.Most of them were also effective in the mouse antithrombotic assay.The compounds were found to be potent antagonists to S2 serotonergic receptor, and good correlation (r = 0.85) between their S2 serotonergic receptor antagonism and their potency as platelet antiaggregatory drugs was observed.Among the compounds studied, monophenoxy>methyl>ethyl>succinate hydrochloride (12b, MCI-9042) was selected for further pharmacological and toxicological evaluation.
