Background:

RG7388 is a second generation clinical MDM2 inhibitor with superior potency and selectivity.
It is a highly potent pyrrolidine compound. RG7388 is more potent and selective than RG7112. In human cancer cell lines, IC50 value of RG7388 in HTRF binding assays is 6 nM and IC50 value of RG7388 in MTT proliferation assays is 0.03μM. [1]
In human cancer cell lines, RG7388 blocks p53−MDM2 binding and e?ectively activates the p53 pathway, leading to cell cycle arrest and/or apoptosis in cell lines expressing wild-type p53 and tumor growth inhibition or regression of osteosarcoma xenografts in nude mice. RG7388 is undergoing clinical investigation in solid and hematological tumors. [1]
In rhabdomyosarcoma xenografts mice, RG7388 increased the activity of Ionizing radiation (XRT) in both rhabdomyosarcoma models and did not increasing local XRT-induced skin toxicity. Changes in TP53-responsive genes were consistent with the synergistic activity of RG7388 and XRT in the Rh18 model. [2]
RG7388 GI50 concentrations of wt p53 was a >200-fold difference versus mutant cell lines. Comparing with MYCN- cells, Tet21N MYCN+ cells were more sensitive to RG7388. In five p53-wt neuroblastoma cell lines, combining use of RG7388 with cisplatin, topotecan, doxorubicin, busulfan and temozolomide were synergistic led to increased apoptosis and higher caspase-3/7 activity. RG7388 is highly potent against p53-wt neuroblastoma cells, and strongly supports its further evaluation as a novel therapy for patients with high-risk neuroblastoma and wt p53 to potentially improve survival and/or reduce toxicity.
