SM-276001 是一种有效的选择性 TLR7 激动剂，可以诱导抗肿瘤免疫反应。SM-276001 是一种具有口服活性的干扰素 (IFN) 诱导剂。
SM-276001 is a potent selective TLR7 agonist that can induce antitumor immune responses. SM-276001 is an orally active interferon (IFN) inducer[1][2].
SM-276001 (1 nM-10 μM) dose-dependently activates NF-κB through human TLR7[2].
SM-276001 demonstrates potent IFN-inducing activity at a dose of 0.1 mg/kg by oral administration in mice[1]. Oral administration of SM-276001, leads to the induction of an inflammatory cytokine and chemokine milieu and to the activation of a diverse population of immune effector cells including T and B lymphocytes, NK and NKT cells[2]. SM-276001 (3 mg/kg PO biweekly) significantly inhibits tumor growth in the Renca renal cell cancer and CT26 colorectal models[2]. SM-276001 (orally; 0.1, 1 or 10 mg/kg) leads to the activation of a diverse population of spleen-resident immune effector cells in Balb/c and C57BL/6J mice. When administered at 1 mg/kg or greater, the plasma concentration of SM-276001 exceeds the MEC of 30 nM[2]. Animal Model: C57BL/6 and B6C3F1 mice bearing Renca or CT26 tumors[2]
