AS 602801 (AS602801) treatment induces cell death and accordingly decreased the number of viable cells in all three cell lines in a dose-dependent manner, suggesting that AS 602801 may have selective cytotoxic activity against neoplastic cells. 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.

Treatment of nude mice bearing xenografts biopsied from women with endometriosis (BWE) with 30 mg/kg AS 602801 (AS602801) causes 29% regression of lesion. Medroxyprogesterone acetate (MPA) or progesterone (PR) alone did not cause regression of BWE lesions, but combining 10 mg/kg AS 602801 with MPA caused 38% lesion regression. 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%). AS 602801 reduces inflammatory cytokines in endometriotic lesions, while levels of cytokines in ipsilateral horns are unaffected. Furthermore, AS 602801 enhances natural killer cell activity, without apparent negative effects on uterus.
