Molecular Weight: 309.33 INK 128 (MLN0128) is a potent and selective mTOR Inhibitor with IC50 of 1 nM; >200-fold less potent to class I PI3K isoforms, superior in blocking mTORC1/2 and sensitive to pro-invasion genes (vs Rapamycin). Phase 1.

INK 128 exhibits an enzymatic inhibition activity against mTOR and more than 100-fold selectivity to PI3K kinases. As TORC1/2 inhibitor, INK 128 inhibits both the phosphorylation of S6
and 4EBP1, the downstream substrates of TORC1, and selectively inhibits
AKT phosphorylation at Ser473, the downstream substrate of TORC2.
Furthermore, INK 128 also shows potent inhibition effects on cell lines
resistant to rapamycin and pan-PI3K Inhibitors.

In a ZR-75-1 breast cancer xenograft model, INK 128 shows tumor growth inhibition efficacy at a dose of 0.3 mg/kg/day. Daily, oral administration of INK 128 inhibits Angiogenesis and tumor growth in multiplexenograft models.


Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)

Species	Baboon	Dog	Monkey	Rabbit	Guinea pig	Rat	Hamster	Mouse
Weight (kg)	12	10	3	1.8	0.4	0.15	0.08	0.02
Body Surface Area (m2)	0.6	0.5	0.24	0.15	0.05	0.025	0.02	0.007
Km factor	20	20	12	12	8	6	5	3

Animal A (mg/kg) = Animal B (mg/kg) multiplied by	Animal B Km
	Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Rat dose (mg/kg) = mouse dose (22.4 mg/kg) ×	mouse Km(3)	= 11.2 mg/kg
	rat Km(6)
