セビドプレニブ(Cevidoplenib)(SKI-O-703)は経口活性かつ選択的な脾チロシンキナーゼ(Syk)阻害剤である。Sykは、免疫性血小板減少症(ITP)などの自己免疫疾患に関与するシグナル伝達経路における重要な制御分子である。セビドプレニブはSKI-O-592のメシル酸塩型でもあり、Sykに対するIC50値は6.2 nMである。
In vitroでは、セビドプレニブ(0~5μM)はマウス初代B細胞を72時間処理し、B細胞受容体(BCR)架橋誘導細胞増殖を濃度依存的に阻害した。また、初期アポトーシス細胞と後期アポトーシス細胞の割合を増加させた。この細胞傷害作用は、LPSによる活性化と比較して、抗IgM mAbでB細胞を活性化した場合に強かった。
In vivoでは、セビドプレニブ(84mg/kg)を全身性エリテマトーデス(SLE)のマウスに経口投与し、IgG自己抗体のレベル、蛋白尿、糸球体腎炎を有意に減少させた。また、体液性免疫反応に関与する胚中心(GC)レベルや、TNFファミリーの血清B細胞活性化因子(BAFF)シグナルを減少させた。セビドプレニブ(42, 84 mg/kg)は、抗リン脂質症候群(APS)マウスに経口投与され、抗リン脂質抗体(APL)レベルを有意に低下させ、マウスの心筋動脈瘤血栓症を予防した。セビドプレニブ(10 mg/kg)は、アルコール性肝疾患(ALD)マウスに経口投与され、肝好中球浸潤を効果的に減少させ、肝障害および脂肪症を抑制した。
