Obatoclax

Catalog No. T41278 CAS 803712-67-6

Obatoclax (GX15-070), a pan-BCL-2 family proteins inhibitor and BH3 mimetic, exhibits a binding affinity (K_i) of 220 nM for BCL-2. It promotes autophagy-dependent cell death and cyclin D1 degradation via the proteasome. Additionally, Obatoclax demonstrates anti-cancer properties and broad-spectrum antiparasitic activity.

Biological Description

Chemical Properties

Storage & Solubility Information

Description	Obatoclax (GX15-070), a pan-BCL-2 family proteins inhibitor and BH3 mimetic, exhibits a binding affinity (K_i) of 220 nM for BCL-2. It promotes autophagy-dependent cell death and cyclin D1 degradation via the proteasome. Additionally, Obatoclax demonstrates anti-cancer properties and broad-spectrum antiparasitic activity.
In vitro	Obatoclax (GX15-070) inhibits several BCL-2 family proteins, with Ki values around 1-7 μM, demonstrating its potency in apoptosis regulation. In colorectal cancer cell lines (HCT116, HT-29, LoVo), it significantly reduces cell numbers in a dose- and time-specific manner, with the IC50 for cell proliferation at 72 hours being 25.85, 40.69, and 40.01 nM, respectively. At 400 nM for 24 hours, Obatoclax induces autophagy in OSCC cells and provokes an increase in G1-phase cell populations at doses of 50-200 nM for 24 hours. Similarly, it decreases cyclin D1 levels significantly at these concentrations. It leads to both phosphorylation-dependent and -independent cyclin D1 degradation in HCT116 and LoVo cells, with a notable decline in p-Cyclin D (T286) levels after treatment. Furthermore, Obatoclax inhibits GSK3β, activates p38 MAPK without significantly affecting ERK1/2 activity in HT-29 cells, and effectively inhibits the clonogenic potential of oral cancer cells across a range of concentrations (50-450 nM), underscoring its broader impact on cancer cell survival and proliferation mechanisms.
In vivo	Obatoclax (GX15-070; administered at doses of 1.15-5 mg/kg intravenously through the lateral tail vein for five consecutive days) demonstrated significant antitumor efficacy in xenograft mouse models in a dose-dependent manner. This study utilized 6-8 week old female BALB/C nude mice with subcutaneous tumors, and the results indicate that increasing doses of Obatoclax correspond to greater antitumor activity.
