Biological Activity

ML323 is a highly potent inhibitor of the USP1-UAF1 deubiquitinase complex with excellent selectivity against human DUBs, deSUMOylase, deneddylase and unrelated proteases. ML323 potentiates cisplatin cytotoxicity in non-small cell lung cancer and osteosarcoma cells. ML323 and related N-benzyl-2-phenylpyrimidin-4-amine derivatives possess nanomolar USP1/UAF1 inhibitory potency.

Protocol
Cell Experiment
Cell lines H596 cells
Preparation method For the colony-forming assay, seeding cells at a density of 300–500 cells per well in six-well plates and growing overnight.Then treating cells with ML323 alone, cisplatin alone or a combination of cisplatin and ML323 (1:1 or 1:4) at the indicated concentrations. Treating cells with an equal volume of DMSO and usinf saline as control. After 48 h of treatment, adding fresh growth medium, and incubating cells for an additional 5-10 d to allow for colony formation. For UV combination treatment, treating the cells with ML323 at the indicated concentrations or an equal volume of DMSO. After 48 h, removing the medium , and irradiating cells at 254 nm at the indicated dosage. Adding fresh growth medium , and incubating the cells for an additional 5-10 d to allow for colony formation. The cells without UV irradiation but treated with ML323 or an equal volume of DMSO are used as controls and designated as 100%. After the formation of the colonies, fixing cells with methanol and stained with 0.5% crystal violet. Colonies consisting of >50 cells are scored. The number of colonies is determined from triplicate plates. The dose-response curves are generated using GraphPad Prism and analyzed by using CalcuSyn to calculate the combination index, which is determined for the fraction of cells affected after the addition of fixed ratios of cisplatin and the USP1-UAF1 inhibitor.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
