Biological Activity

Bentamapimod, also known as AS602801, is an ATP-competitive JNK inhibitor with IC50 of 80 nM, 90 nM, and 230 nM for JNK1, JNK2, and JNK3, respectively. AS 602801 exhibits cytotoxicity against both serum-cultured non-stem cancer cells and cancer stem cells derived from human pancreatic cancer, non-small cell lung cancer, ovarian cancer and glioblastoma at concentrations that did not decrease the viability of normal human fibroblasts. AS 602801 also inhibits the self-renewal and tumor-initiating capacity of cancer stem cells surviving AS 602801 treatment.

In vivo: Bentamapimod (30 mg/kg) on nude mice bearing xenografts biopsied from women with endometriosis (BWE) causes 29% regression of lesion. In human endometrial organ cultures (from healthy women), treatment with AS-602801 or MPA reduced matrix metalloproteinase-3 (MMP-3) release into culture medium. In organ cultures established with BWE, PR or MPA failed to inhibit MMP-3 secretion, whereas AS 602801 alone or MPA + AS 602801 suppresses MMP-3 production. In an autologous rat endometriosis model, AS 602801 causes 48% regression of lesions compared to GnRH antagonist Antide (84%). Bentamapimod reduces inflammatory cytokines in endometriotic lesions, while levels of cytokines in ipsilateral horns are unaffected.

Cell Experiment
Cell lines PANC-1, A2780, and A549 human cancer cells
Preparation method Bentamapimod (AS602801) is dissolved in DMSO (10 mM) and stored, and then diluted with appropriate media before use. PANC-1, A2780, and A549 human cancer cells and IMR90 human normal fibroblasts are treated without (control) or with the indicated concentrations of AS 602801 (2.5, 5, and 7.5 μM) for 3 days. The number of viable cells (left panels) and the percentage of dead cells (right panels) are determined using trypan blue as a vital dye.
Concentrations 2.5, 5, and 7.5 μM
Incubation time 3 days
Animal Experiment
Animal models 5-week-old athymic (ncr/nude) ovariectomized mice
Formulation dissolved in in DMSO (10 mM) and diluted with PBS
Dosages 10 mg/kg and 30 mg/kg/animal for 30 days
Administration gavage

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
