生物活性

VNPP433-3β (Galeterone 3β-imidazole) hydrochloride is an orally active molecular glue degrader, which degrades androgen receptor (AR) and its splice variants (AR-Vs) and MAP kinase-interacting serine/threonine protein kinase Mnk1/2. VNPP433-3β hydrochloride induces cell apoptosis. VNPP433-3β hydrochloride inhibits tumor growth in the CWR22Rv1 xenograft mouse model. VNPP433-3β hydrochloride can be used for the study of castration resistant prostate cancer (CRPC) and pancreatic ductal adenocarcinoma (PDAC)[1].

体外研究
(In Vitro)

VNPP433-3β (compound 4) hydrochloride 具有强大的抗增殖活性,对 LNCaP (雄激素敏感)、C42B (雄激素不敏感) 和 CWR22Rv1 (去势抵抗) 的 GI50 分别为 0.28 μM、0.33 μM 和 0.26 μM[1]
VNPP433-3β (5-20 μM;24 小时) hydrochloride 在人类 CWR22Rv1 前列腺癌细胞中可降解 AR/AR-V7 和 Mnk1/2,从而分别抑制 AR 信号传导和消耗 peIF4E,并调节下游分子靶点[1]

Western Blot Analysis[1]

Cell Line: CWR22Rv1 prostate cancer cells
Concentration: 5, 10 and 20 μM
Incubation Time: 24 h
Result: Significantly and dose-dependently reduced the expressions of Mnk1, and peIF4E.
Caused significant depletion of the downstream target, cyclin D1, and induction of apoptosis via significant downregulation of antiapoptotic Bcl-2 and upregulation of proapoptotic Bax.
体内研究
(In Vivo)

VNPP433-3β (5 和 20 mg/kg;口服;每周 5 天;共 16 天) hydrochloride 在 CWR22Rv1 肿瘤异种移植瘤中显示出抗肿瘤活性[1]

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

Animal Model: Male NRG mice (5-6 weeks) bearing CWR22Rv1 tumors[1]
Dosage: 5 and 20 mg/kg
Administration: p.o.; 5 days per/week; for 16 days
Result: Inhibited tumor growth with TGIs of 139.6 % at 20mg/kg, and 74.2% at 5 mg/kg.
Caused a potent inhibition/regression of aggressive and difficult-to-treat CWR22Rv1 tumor xenografts growth, with no apparent host toxicities.

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.
