Sabizabulin

VERU-111 (ABI-231) is a potent and orally active α and β tubulin inhibitor, which displays strong antiproliferative activity, with an average IC₅₀ of 5.2 nM against panels of melanoma and prostate cancer cell lines. VERU-111 (ABI-231) suppresses tumor growth and metastatic phenotypes of cervical cancer cells via targeting HPV E6 and E7, and has potential for the treatment of prostate cancer^[1][2][3]. IC50 & Target: tubulin^[1] In Vitro: VERU-111 (2.5-80 nM; 24-48 hours) inhibits Panc-1, AsPC-1 and HPAF-II cells growth in a dose and time-dependent manner (24 hours: IC₅₀s of 25, 35 and 35 nM, respectively; 48 hours: IC₅₀s of 11.8, 15.5, and 25 nM, respectively)^[4].
VERU-111 (5-20 nM; 24 hours) arrests Panc-1 and AsPC-1 cells in G2/M phase in a dose-dependent manner^[4].
VERU-111 (5-20 nM; 24 hours) shows dose-dependent inhibition of pro-Caspase 3 and 9 and activation of Caspase-3 and 9, induces the expression of Bax and Bad, and inhibits the expression of Bcl-2 and Bcl-xl proteins in both AsPC-1 and Panc-1 cells^[4]. In Vivo: VERU-111 (50 μg/mouse; intra-tumorally; 3 times per week for 3 weeks) effectively inhibits tumor growth as compared to vehicle-treated group. None of the mouse showed any apparent toxicity as constant increase of body weight in VERU-111 treated mice^[4].
