OC000459是一种有效的具有口服活性的D前列腺素受体2(DP2)选择性拮抗剂,Ki值为4 nM[1].
DP2在Th2细胞和嗜酸性粒细胞上表达,可被PGD2激活,据报道这对过敏性疾病的发病机制有影响.作为DP2的拮抗剂,OC000459可防止PGD2结合人类DP2和大鼠重组DP2,Ki值分别为4 nM和3 nM.在表达DP2的CHO细胞中,OC000459可抑制PGD2介导的钙动员,IC50值为28 nM.在人类Th2细胞中,OC000459可抑制应答PGD2的趋化作用和IL-13合成,IC50值分别为28 nM和19 nM.此外,口服OC000459可有效减少大鼠血液中的嗜酸性粒细胞.OC000459在豚鼠中也对DK-PGD2雾化的嗜酸性粒细胞积累有抑制作用.另外,OC000459也可抑制哮喘病人的晚期过敏反应[1,2].
