Molecular Weight:

504.23 TAK-733 is a potent and selective MEK allosteric site inhibitor for MEK1 with IC50 of 3.2 nM, inactive to Abl1, AKT3, c-RAF, CamK1, CDK2, c-Met, etc. Phase 1.


Biological Activity


TAK-733 is highly potent and selective MEK allosteric site inhibitor
with IC50 of 3.2 nM. TAK-733 shows potent enzymatic and cell activity
with an EC50 of 1.9 nM against ERK phosphorylation in cells.


TAK-733 demonstrates broad antitumor activity in mouse xenograft models
of human cancer including models of melanoma, colorectal, NSCLC,
pancreatic and breast cancer. TAK-733 is well tolerated with
pharmacokinetics and pharmacodynamics that support once-daily oral
dosing in humans. TAK-733 shows maximally efficacious doses at once
daily orally doses of 10 mg/kg.

Animal Study: [2]

Animal Models	Human solid tumor xenograft models including NSCLC (NCI H23 [KRAS and LKB1 mutations]), CRC (SW620 [KRAS, APC, p53 mutations]) Pancreatic cancer (Panc 1 and Capan 1 [KRAS mutations] and BxPC-3 [No MAPK mutations]) models in immunocompromised mice.
Formulation	Saline
Dosages	10 mg/kg
Administration	Orally administrated once daily for 21 days

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
