RMC-6272 (RM-006) is a bi-steric mTORC1-selective inhibitor. RMC-6272 exhibits potent and selective (> 10-fold) inhibition of mTORC1 over mTORC2. RMC-6272 shows improved inhibition of mTORC1 in comparison to Rapamycin, and induces more cell death in TSC2 null tumors[1].
RMC-6272 shows more effective growth inhibition in multiple TSC1 or TSC2 mutant tumor cell lines compared to Rapamycin. RMC-6272 causes a more profound growth inhibition in the TSC1 or TSC2 mutant cells than the wild type cells. RMC-6272 at ~1 nM shows near complete inhibition of p4E-BP1T37/46, while inhibition of pS6S240/244 levels is similar for Rapamycin and RM compounds[1].
RMC-6272 markedly reduces kidney tumor burden in Tsc2+/- A/J mice after four weeks of treatment. Tumor regrowth is assessed two months after treatment cessation, tumor burden is significantly reduced in the RMC-6272 group as compared to the Rapamycin and MLN0128 groups[1].

Discovery of RMC-5552, a Selective Bi-Steric Inhibitor of mTORC1, for the Treatment of mTORC1-Activated Tumors
J Med Chem 2023 Jan 12;66(1):149-169.PMID:36533617DOI:10.1021/acs.jmedchem.2c01658.
Hyperactivation of mTOR kinase by mutations in the PI3K/mTOR pathway or by crosstalk with other mutant cancer drivers, such as RAS, is a feature of many tumors. Multiple allosteric inhibitors of mTORC1 and orthosteric dual inhibitors of mTORC1 and mTORC2 have been developed as anticancer drugs, but their clinical utility has been limited. To address these limitations, we have developed a novel class of "bi-steric inhibitors" that interact with both the orthosteric and the allosteric binding sites in order to deepen the inhibition of mTORC1 while also preserving selectivity for mTORC1 over mTORC2. In this report, we describe the discovery and preclinical profile of the development candidate RMC-5552 and the in vivo preclinical tool compound RMC-6272. We also present evidence that selective inhibition of mTORC1 in combination with covalent inhibition of KRASG12C shows increased antitumor activity in a preclinical model of KRASG12C mutant NSCLC that exhibits resistance to KRASG12C inhibitor monotherapy.
Translatome analysis of Tuberous Sclerosis Complex-1 patient-derived neural progenitor cells reveal rapamycin-dependent and independent alterations
Res Sq 2023 Mar 27;rs.3.rs-2702044.PMID:37034588DOI:10.21203/rs.3.rs-2702044/v1.
Tuberous sclerosis complex (TSC) is an inherited neurocutaneous disorder caused by mutations in TSC1 or TSC2 genes, with patients often exhibiting neurodevelopmental (ND) manifestations termed TSC-associated neuropsychiatric disorders (TAND) including autism spectrum disorder (ASD). The hamartin-tuberin (TSC1-TSC2) protein complex inactivates mechanistic target of rapamycin complex 1 (mTORC1) signaling, leading to increased protein synthesis via inactivation of translational repressor eIF4E-binding proteins (4E-BPs). In TSC1 -null neural progenitor cells (NPCs), we previously reported early ND phenotypic changes, including increased proliferation/altered neurite outgrowth, which were unaffected by mTORC1-inhibitor rapamycin. Here, using polysome-profiling to quantify translational efficiencies at a transcriptome-wide level, we observed numerous TSC1-dependent alterations in NPCs, largely recapitulated in post-mortem brains from ASD donors. Although rapamycin partially reversed TSC1-associated alterations, most neural activity/synaptic- or ASD-related genes remained insensitive but were inhibited by third-generation bi-steric, mTORC1-selective inhibitor RMC-6272, which also reversed altered ND phenotypes. Together these data reveal potential implications for treatment of TAND.
