| Questions And Answer | Back Directory | [Description]
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. | [In vitro]
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. | [In vivo]
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. |

TAK-733 is a potent and selective MEK allosteric site inhibitor with an IC50 of 3.2 nM. | [Biological Activity]
tak-733 is a potent, atp-noncompetitive and selective inhibitor of mek allosteric site with the ic50 value of 3.2nm [1].tak-733 has been shown potent enzymatic and cell activity with an ic50 value of 3.2nm against constitutively active mek enzyme and an ec50 of 1.9nm against erk phosphorylation in cells. in addition, tak-733 has also shown the low clearance and high oral bioavailability based on the pharmacokinetics of tak-733 in all species (mouse, rat, dog and monkey). furthermore, tak-733 has been reported to broad inhibit tumor activity in mouse xenograft models of human cancer (melanoma, colorectal, nsclc, pancreatic and breast cancer) [1]. | [Synthesis]
Example 18: (i) To a solution of 3-(2,3-dihydroxypropyl)-5-(2-fluoro-4-iodophenylamino)-8-methylpyrido[2,3-d]pyrimidin-4,7(3H,8H)-dione (Example 6) (1 g, 2.06 mmol, 1 eq.) in DMF (19 mL) was added dropwise under nitrogen protection at ambient temperature a solution of Selectfluor (801 mg, 2.26 mmol, 1.1 eq.) in a mixture of acetonitrile (9 mL) and DMF (5 mL). The reaction mixture was stirred at ambient temperature for 10 minutes and then filtered. The filtrate was purified by preparative LC/MS (30-55% CH3CN/H2O) to afford (R)-3-(2,3-dihydroxypropyl)-6-fluoro-5-(2-fluoro-4-iodophenylamino)-8-methylpyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione (Example 18) as an off-white solid. The recovered feedstock was reacted under the same reaction conditions to give a second batch of product. The total yield was 347 mg (33%).1H NMR (400 MHz, DMSO-J6) δ ppm 3.36-3.40 (m, 1H), 3.43-3.50 (m, 1H), 3.58 (s, 3H), 3.61-3.72 (m, 1H), 3.72-3.82 (m, 1H), 4.27-4.37 (m, 1H) , 4.78-4.87 (m, 1H), 5.14 (d, J = 5.81 Hz, 1H), 6.93-7.03 (m, 1H), 7.53 (d, J = 8.84 Hz, 1H), 7.65-7.74 (m, 1H), 8.52 (s, 1H), 10.25 (d, J = 10.1 Hz, 1H). The calculated value for [M + H] C17H15F2IN4O4 is 505; the measured value is 505. | [target]
