I-138

Catalog No.: GC69249Purity:>98%

I-138 is an orally effective compound structurally related to ML323. I-138 and ML323 are potent USP1-UAF1 reversible inhibitors. I-138 displays synergistic binding with ubiquitin and mutually exclusive binding with ML323. I-138 induces mono-ubiquitination of FANCD2 and PCNA in MDA-MB-436 cells, increasing mono-ubiquitination of PCNA and FANCD2 in HAP-1 USP1 WT cells. I-138 eliminates self-cleavage of USP1 in cells.
