INK 128 (MLN0128) is a selective inhibitor of mTOR with IC50 value of 1 nM [3].
mTOR (mammalian target of rapamycin) is an evolutionarily conserved serine/threonine kinase which combined PI3K/AKT/mTOR pathway and plays an important role in regulating many fundamental features of cell growth and division [1].
INK 128 (MLN0128) is a potent mTOR inhibitor. When tested with human pancreatic cancer cells, INK-128 treatment inhibited cell growth and survival via inhibiting mTOR in a time- and concentration- dependent manner [2]. In HER2-positive breast cell lines, INK 128 treatment significantly delayed cell cycle and inhibited cell proliferation through inhibiting mTOR [1].
In a ZR-75-1 breast cancer xenograft model, INK128 treatment in a dose of 0.3mg/Kg/day significantly inhibited tumor growth. When combined with other standard targeted therapy or chemotherapy such as sorafenib, sutent and paclitaxel, enhanced anti-tumor growth activity was observed. INK128 is reported to have excellent physiochemical properties and is currently undergoing preclinical evaluation [3]. When tested with MDA-MB361 mouse model, administration of INK 128 showed a resistance after 20 days, and combined with lapatinib resulted in long-lasting tumor regression [1].

| Kinase experiment [1]: | |
|
Kinase assays |
mTOR activity was assayed using LanthaScreen Kinase kit reagents. PI(3)K α, β, γ and δ activity were assayed using the PI(3)KHTRF assay kit. The concentration of INK 128 necessary to achieve inhibition of enzyme activity by 50% (IC50) was calculated using concentrations ranging from 20 μM to 0.1 nM (12-point curve). IC50 values were determined using a nonlinear regression model. |

Preparation method |
The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months. |
|
Reacting condition |
10 ~ 100 nM; 72 hrs |
|
Applications |
INK 128 time- and dose-dependently inhibited the survival of PANC-1 cells, and significantly reduced the viability of PANC-1 cells at the concentrations of 10 ~ 100 nM. There was no significant viability decrease until 48 hrs after INK 128 treatment. |

Dosage form |
0.3 mg/kg/day; p.o. |
|
Applications |
In a ZR-75-1 breast cancer xenograft model, INK 128 significantly inhibited tumor growth. The combination therapy of INK 128 and other standard targeted therapy or chemotherapy such as Sorafenib, Sutent and Paclitaxel enhanced anti-tumor growth activity. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
