MTI-31
Based on 1 publication(s) in Google Scholar
MTI-31 (LXI-15029) is a potent, orally active and highly selective inhibitor of mTORC1 and mTORC2. MTI-31 is selective for mTOR (Kd: 0.20 nM) versus PIK3CA, PIK3CB and PIK3G with >5,000 fold selectivity in mTOR binding assays. MTI-31 shows an IC50 of 39 nM for mTOR in LANCE assay of mTOR substrate phosphorylation with 100 μM ATP. MTI-31 can be used for the research of breast cancer.

MTI-31 acts as a potent and selective inhibitor of mTOR enzymatic activity capable of targeting both mTORC1 and mTORC2 functions in cancer cells[1].
MTI-31 (0.01-100 μM) elicits a potent and more substantial inhibition of cell growth than that of Rapamycin[1].
Treatment with MTI-31 for 6 h demonstrates a dose-dependent inhibition of both the mTORC1 substrates P-S6K1(T389), P-S6(S235/6), P-4EBP1(T70) and mTORC2 substrate P-AKT(S473), achieving 50% inhibition at ≤0.12 μM in three representative tumor cell lines harboring mTOR pathway dysregulation (786-O renal, U87MG glioma and MDA-MB-453 breast)[1].
MTI-31-induced apoptosis requires mTORC2-regulated Bim- and GSK3 activity[1].

Cell Line:MDA-MB-453 cells

Cell Line:786-O renal, U87MG glioma and MDA-MB-453 breast cells
-
Concentration:0.12, 0.37, 1.11, 3.33, 10 μM

Incubation Time:6 hours
-
Result:Demonstrated a dose-dependent inhibition of both the mTORC1 substrates P-S6K1(T389), P-S6(S235/6), P-4EBP1(T70) and mTORC2 substrate P-AKT(S473).
Treatment of tumor bearing nude mice with orally administered MTI-31 inhibits growth of H1975 tumors (25 mg/kg/d; orally) or U87MG tumors (30 mg/kg/d; orally)[2].

Animal Model:Female nude mice bearing tumors of MDA-MB-453, 786-O or HCC1806[1]
-
Dosage:2.5, 5, 10, 20, 40 mg/kg for MDA-MB-453 and 786-O; 20 and 40 mg/kg for HCC1806
-
Administration:Treated orally via a once daily (qd) regimen
-
Result:Was efficacious in several tumor models harboring HER2+/PIK3CAmut and/or PTEN-deficiency exemplified by MDA-MB-453 and 786-O. Demonstrated a dose proportional tumor growth inhibition (TGI) with a minimum efficacious dose (MED) of 5 mg/kg (>50% TGI, p<0.01) and a maximum tolerated dose (MTD) of 40 mg/kg (7-15% body weight loss without mortality).
In contrast, had limited efficacy in the HER2-/PIK3CAwt HCC1806 breast tumor model even at the highest 40 mg/kg.
