NS-3728 (Endovion) is an orally active chloride channel blocker for the treatment of cancer. Endovion was originally discovered by NeuroSearch. In August 2004, NeuroSearch entered into a collaboration with TopoTarget to develop its compound Endovion, an orally active chloride channel blocker for the treatment of cancer. Endovion blocks a certain subtype of chloride ion channels important for cell division, cell migration and the formation of new blood vessels (angiogenesis). Endovion has shown efficacy in preclinical cancer models. The compound has completed Phase I clinical trials in 92 subjects. Endovion had been in phase I clinical trials for the treatment of sickle cell anemia and solid tumours. TopoTarget has discontinued development of Endovion for use in glioblastoma. It was discontinued as supplementary preclinical trials did not support its activity as an anticancer agent. Early studies as an anti sickling agent were discontinued due to higher costs than first estimated for the clinical programme.

Sample Use Guides

The in vivo anti-tumor effect of NS-3728 on C6 glioma cells given either as monotherapy (40 mg/kg/day) or in combination with temozolomide (Temodal, 25 or 5 mg/kg/day) was tested in two separate experiments, using either the xenograft method or the subcutaneous air sac rat model. Oral administration of NS-3728 (40 mg/kg/day) in combination with temozolomide (25 mg/kg/day) resulted in a significant reduction of growth rate, whereas neither NS-3728 (40 mg/kg/day) nor temozolomide (25 mg/kg/day) exhibited any significant anti-tumor effect when given as monotherapy
Route of Administration: Oral
NS-3728 inhibited the VRAC current in HEK293 cells with IC50 value of 0.40 uM.
