Optimizing the Physicochemical Properties of Raf/MEK Inhibitors by Nitrogen Scanning
摘要:
Substituting a carbon atom with a nitrogen atom (nitrogen substitution) on an aromatic ring in our leads 1 la and 13g by applying nitrogen scanning afforded a set of compounds that improved not only the solubility but also the metabolic stability. The impact after nitrogen substitution on interactions between a derivative and its on- and off-target proteins (Raf/MEK, CYPs, and hERG channel) was also detected, most of them contributing to weaker interactions. After identifying the positions that kept inhibitory activity on HCT116 cell growth and Raf/MEK, compound I (CH5126766/RO5126766) was selected as a clinical compound. A phase I clinical trial is ongoing for solid cancers.
The present invention provides a compound represented by general formula (1) below or a pharmaceutically acceptable salt thereof:
wherein: X is selected from heteroaryl etc., Y1 and Y2 are selected from —N═ etc., Y3 and Y4 are selected from —CH═ etc., A is selected from sulfamide etc., R1 is selected from hydrogen etc., and R2 is selected from C1-6 alkyl etc. The compound or salt has sufficiently high antitumor activity, and is useful in the treatment of cell proliferative disorders, particularly cancers. The present invention also provides a pharmaceutical composition containing the compound or salt as an active ingredient.
