Biological Activity

Description

Nedisertib (M3814, Peposertib, MSC2490484A) is an orally bioavailable, highly potent and selective inhibitor of DNA activated protein kinase (DNA-PK) with IC50 of < 3 nM.

Targets

DNA-PK ^[1]
(Cell-free assay)

3 nM

In vitro

M3814 potently inhibits DNA-PK catalytic activity and sensitizes multiple cancer cell lines to ionizing radiation (IR) and DSB-inducing agents. Inhibition of DNA-PK autophosphorylation in cancer cells leads to an increased number of persistent DSBs.^[2]

In vivo

Inhibition of DNA-PK autophosphorylation in xenograft tumors leads to an increased number of persistent DSBs. Oral administration of M3814 to two xenograft models of human cancer, using a clinically established 6-week fractionated radiation schedule, strongly potentiates the antitumor activity of IR and lead to complete tumor regression at nontoxic doses.^[2]

Protocol (from reference)

Cell Assay:^{^[2]}	Cell lines 92 cancer cell lines and resting peripheral blood mononuclear cells (PBMCs) Concentrations 5 μmol/L–5 nmol/L Incubation Time 120 h Method Radiosensitization of 92 cancer cell lines and resting peripheral blood mononuclear cells (PBMCs) by M3814 is performed at Oncolead. Cell viability is determined with 3 Gy IR, M3814 (5 μmol/L–5 nmol/L), and a combination of 3 Gy IR and M3814 (5 μmol/L–5 nmol/L). Treated cells are incubated for 120 hours, fixed, stained with sulforhodamine B, and quantified colorimetrically.
Animal Study:^{^[2]}	Animal Models 7- to 9-week-old female NMRI (nu/nu) mice Dosages 5 mg/kg, 25 mg/kg, 100 mg/kg Administration Oral gavage
