Antineoplastic activity of GP-2250 in-vitro and in mouse xenograft models.

ABSTRACT: This study examined the antineoplastic effects of GP-2250 (misetionamide), an oxathiazine derivative with broad activity, in multiple cancer cell lines and mouse xenograft models. Antineoplastic activity of GP-2250 was tested in >300 cancer cell lines using the OncoPanel cytotoxicity assay. GP-2250 activity was further tested in mouse xenograft models, in which GP-2250 or vehicle (10 ml/kg) was administered daily for 28 days by intraperitoneal injection in the lower right abdomen of CrTac:NCR-Foxn1nu mice with tumor volumes of 100 to 200 mm3. In the in-vitro models, GP-2250 increased cytotoxicity readings with IC50 and EC50 as well as indications of cell cycle blockage in pancreatic and ovarian cell lines. In mouse xenograft models, a reduction of 30-40% in tumor volume occurred in the GP-
