MedKoo CAT#: 205816

CAS#: NONE

Description: ARQ-761 is a soluble prodrug of beta-lapachone with potential antineoplastic and radiosensitizing activity. ARQ 761 is converted to beta-lapachone (b-lap) in vivo. When b-lap is activated by NAD(P)H:quinone oxidoreductase-1 (NQO1) this agent creates a futile oxidoreduction, generating highly reactive oxygen species (ROS) that results in DNA damage. The activation of b-lap also causes hyperactivation of poly (ADP-ribose) polymerase-1 (PARP-1), an enzyme that facilitates DNA repair, accompanied by rapid depletion of NAD+/ATP nucleotide levels.
