VNPP433-3β hydrochloride
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).

VNPP433-3β (compound 4) hydrochloride possess potent antiproliferative activities with GI50 of 0.28 μM, 0.33 μM, 0.26 μM against LNCaP (androgen-sensitive), C42B (androgen-insensitive) and CWR22Rv1 (castration-resistant), respectively[1].
VNPP433-3β (5-20 μM; 24 h) hydrochloride can degrade AR/AR-V7 and Mnk1/2 with consequent inhibition of AR signaling and depletion of peIF4E, respectively, and modulation of the downstream molecular targets in human CWR22Rv1 prostate cancer cells[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.

-
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.
