IDB-003
IDB-003 is an orally active inhibitor of the human ribosomal peptidyl transferase center (PTC). IDB-003 exhibits antiproliferative activity against MYC-dependent cancer cells. IDB-003 binds to PTC, maintains ribosomal RNA interactions, blocks translation via context-dependent nascent polypeptide chain interactions, depletes MYC and CCND1, activates JNK phosphorylation through ribosomal collision, and downregulates the MYC target pathway. IDB-003 inhibits the growth of triple-negative breast cancer xenografts in mice. IDB-003 can be used for the research of triple-negative breast cancer.

IDB-003 (72 h) potently inhibits the proliferation of 22Rv1, HCC-1143, LS411N and MCF7 cancer cells (EC50 values 0.021-0.132 μM), while exhibits weak activity against MRC5 fibroblasts (EC50 0.331 μM)[1].
IDB-003 (1-10 μM; 2 h-<4 h) depletes the short-lived oncoproteins MYC and CCND1 in MCF7 cells: this depletion is achieved within 2-4 h at treatment concentrations of 1 μM and 10 μM, respectively, without altering the levels of the long-lived proteins CDK4 and tubulin[1].
IDB-003 (2-72 h) depletes MYC protein in HCC-1143 cells in a concentration-dependent manner within 2 h, which correlates with reduced cell viability after 72 h of treatment[1].
IDB-003 (1.27 μM; 60 min) induces context-dependent translation arrest in HCC-1143 cells, preferentially targeting nascent polypeptide chains with an aliphatic residue at position −1[1].
