MG-002
MG-002 is an orally active eIF4A1 and eIF4A2 inhibitor with a human eIF4A1 IC50 of 43 nM. MG-002 prevents competent ribosome recruitment to mRNA, inhibits cap-dependent mRNA translation, and engages eIF4A2 via the same RNA clamping mechanism to inhibit mRNA translation. MG-002 induces G2/M cell cycle delay, induces apoptosis, suppresses synthesis of c-MYC and cyclin D1, and shows minimal overt toxicity in mice. MG-002 inhibits primary triple-negative breast cancer tumor growth, attenuates metastatic spread, and enhances anti-neoplastic activity of Doxorubicin (HY-15142A) in pre-clinical models.

MG-002 (10 μM; 30 min) stabilizes eIF4A1 binding to polypurine poly(AG)8 RNA with a longer complex half-life than eFT226[1].
MG-002 (15 μM) stabilizes recombinant eIF4A1 protein structure via RNA clamping, as shown by a 7.2 °C ΔT50 shift in DSF analysis[1].
MG-002 (0.1-1000 nM; 1 h) potently inhibits cap-dependent mRNA translation in Krebs-2 extracts with an IC50 of 43 nM, while sparing eIF4A-independent HCV IRES-driven translation[1].
MG-002 (1-1000 nM; 1 h) potently inhibits protein synthesis in eHAP1 haploid leukemia cells after 1 h of exposure[1].
MG-002 (0.01-100 nM, 3 μM; 2-4 d) potently reduces viability of 4T1, BT474, and MDA-MB-231 breast cancer cells with EC50 values of ~1 to 10 nM, while exerting only modest cytostatic effects on non-transformed IMR-90, MRC-5, and HUVEC cells[1].
MG-002 (0.1-10000 nM; 2 d) exerts its cytotoxic effects primarily through engagement of eIF4A1 and eIF4A2[1].
MG-002 (7 nM; 72 h) inhibits mRNA translation in 4T1-526 TNBC cells with an IC50 of ~7 nM and induces significant cell death after 72 h of exposure to this concentration[1].
MG-002 (10 nM) induces a significant G2/M progression delay in MDA-MB-231 TNBC cells post-release from S phase block[1].
MG-002 (100 nM; 24 h) reduces eIF4F-sensitive c-MYC and cyclin D1 protein levels in MDA-MB-231, 4T1, and MRC-5 cells, and induces apoptosis (PARP cleavage) in MDA-MB-231 and 4T1 cancer cells but not in non-transformed MRC-5 cells[1].
