IC50: ML-323 is a highly potent and selective inhibitor of USP1-UAF1 with IC50 value of 76 nM.
ML-323 is an inhibitor of USP1-UAF1 with remarkable selectivity and relatively low cytotoxicity to the human cells. [1] USP1-UAF1 is closely linked to the DNA damage response and is recently suggested as a strategy for overcoming drug resistance during antitumor therapy. [1]
In vitro: Studies in H596 cells showed that ML-323 blocked the deubiquitination of PCNA and FANCD2 via suppressing USP1–UAF1 activity. It was reported that ML-323 potently inhibited USP1-UAF1 with IC50 values of 76 nM and 174 nM in ubiquitin-rhodamine (Ub-Rho) assay and orthogonal gel-based assay, respectively. In addition, by targeting TLS and FA, two major DNA damage response pathways, ML-323 increased cisplatin cytotoxicity both in NSCLC H596 cells and U2OS osteosarcoma cells. Moreover, this agent exhibited a high selectivity to human DUBs, deSUMOylase, deneddylase and unrelated proteases. [1]
In vivo: So far, no in vivo study has been conducted.
Clinical trial: So far, no clinical trial has been conducted.
