RMC-5552

RMC-5552 is a potent and selective inhibitor of mTORC1 that blocks phosphorylation of downstream signaling targets pS6K and p4EBP1 with IC50 values of 0.14 nM and 0.48 nM, respectively. RMC-5552 shows markedly reduced inhibition of pAKT (IC50 19 nM), achieving approximately 40-fold selectivity for mTORC1 over mTORC2. RMC-5552 has demonstrated anticancer activity, supporting its potential use as a therapeutic agent in oncology and as a research tool for dissecting mTOR signaling pathways.
