RMC-5552
Based on 6 publication(s) in Google Scholar
RMC-5552 is a potent and selective mTORC1 inhibitor. RMC-5552 inhibits phosphorylation of mTORC1 pS6K and p4EBP1 with IC50s of 0.14 nM and 0.48 nM, respectively. RMC-5552 shows much lower pAKT inhibition (IC50 of 19 nM), resulting in mTORC1/mTORC2 selectivity approaching 40-fold. RMC-5552 has anti-cancer activity.

mTORC1 |
The presence of FKBP12, whose recruitment would only be observed in the presence of the FKBP12-FRB allosteric modality of RMC-5552. Density for RMC-5552 is evident at the interface between FKBP12 and the FRB domain of mTOR. RMC-5552 makes hydrogen bonds to the backbone of G2238 and V2240, the “hinge” of mTOR, via the 4-aminopyrazolo[3,4-d]pyrimidine core, and the 2-aminobenzoxazole makes hydrogen-bonding interactions to E2190 and K2187[1].
