生物活性

WCY-8-67 is an orally active and selective USP5 inhibitor, with an IC50 value of 1.33 μM. WCY-8-67 induces apoptosis and suppresses JAK/STAT3 and PI3K/AKT signaling pathways in vitro. WCY-8-67 inhibits proliferation of AE-positive AML cells, induces G1 phase arrest and differentiation of AML cells. WCY-8-67 demonstrates potent anti-leukemic efficacy in mice. WCY-8-67 can be used for the study of acute myeloid leukemia[1].

体外研究
(In Vitro)

WCY-8-67 (0.5-2 μM, 24 h) 以剂量依赖方式降低 Kasumi-1 和 Skno-1 细胞中的 AML1-ETO (AE) 蛋白丰度[1]
WCY-8-67 (0.5-2 μM, 24 h) 抑制 AE 阳性 AML 细胞的增殖(Kasumi-1: IC50 = 1.75 μM; Skno-1: IC50 = 0.99 μM; U937-AE: IC50 = 1.20 μM),但对 AE 阴性 AML 细胞(MV-4-11, MOLM-13, HL-60)影响甚微[1]
WCY-8-67 (0.5-7.5 μM, 24-48 h) 在 Kasumi-1 和 Skno-1 细胞中诱导凋亡和 G1 期细胞周期阻滞[1]
WCY-8-67 (0.5-2 μM, 7 days) 在琼脂糖菌落实验中减少 Kasumi-1 和 Skno-1 细胞的菌落形成,降低恶性克隆数量[1]
WCY-8-67 (0.5-2 μM, 24 h) 减少 Kasumi-1 和 Skno-1 细胞中的 CD34+CD38- 白血病干细胞 (LSC) 群体,并增加 CD11b+ 分化细胞群体[1]
WCY-8-67 (0-2.5 μM, 24 h) 在 Kasumi-1 和 Skno-1 细胞中抑制 JAK/STAT3 和 PI3K/AKT 信号通路[1]

体内研究
(In Vivo)

WCY-8-67 (20-40 mg/kg,口服,每日一次,12 天) 在 Skno-1 皮下异种移植模型中显示出强效的抗肿瘤活性[1]
WCY-8-67 (40 mg/kg,口服,每日一次,42 天) 在 Kasumi-1-luciferase-GFP 原位异种移植模型中减少肿瘤负荷并延长生存期[1]
WCY-8-67 (20 mg/kg,腹腔注射,每日一次,14 天) 在 t(8;21) AML 异种移植 (PDX) 模型中延长生存期并减轻脾脏重量[1]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Skno-1 cells (1 × 107) were subcutaneously implanted into the flanks of 6-week-old female NU/NU mice[1]
Dosage: 20, 40 mg/kg
Administration: p.o., once daily, 12 days
Result: Reduced tumor weight and volume.
Showed no significant changes in body weight.

Dosage: 40 mg/kg
Administration: p.o., once daily, 42 days
Result: Decreasedspleen weight and hCD45+ leukemic cell percentage in bone marrow, spleen, and peripheral blood.
Reduced tumor burden and extends survival.
Animal Model: Primary t(8;21) AML cells were intravenously injected into the tail veins of the 6-week-old NOG mice[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
