  • Publication number: 20240352000
    Abstract: The present invention relates to a pyrimidine-2,4-diamine derivative, a method for preparing the same, and a pharmaceutical composition for preventing or treating cancer, comprising the same as an active ingredient. The pyrimidine-2,4-diamine derivative exhibits a high inhibitory ability against EGFR and HER2 mutations, and thus can be advantageously used in the treatment of cancer in which EGFR and HER2 mutations have occurred. In addition, the pyrimidine-2,4-diamine derivative exhibits a significant synergistic effect when administered in combination, and thus may be advantageously used in combination therapy.

  • Publication number: 20220249482
    Abstract: The present invention relates to a N2,N4-diphenylpyrimidin-2,4-diamine derivative, a method for preparing the same, and a pharmaceutical composition for the prevention or treatment of cancer, containing the same as an active ingredient. The derivative shows a relatively weak EGFR activity inhibitory effect on wild-type EGFR, a high inhibitory ability on EGFR mutation, and a high inhibitory ability on even FLT3 and FLT3 mutation, and thus, can be effectively used for the treatment of cancer with EGFR mutation or cancer with FLT3 or a mutation thereof, and the derivative shows a synergy effect at the time of combination administration, and thus can be effectively used for the treatment of combination administration.

  • Patent number: 10647686
    Abstract: The present invention relates to compounds represented by Formula 1 or a pharmaceutically acceptable salt thereof, wherein: R1 is chloro or methyl; R2 is hydrogen or chloro; R3 is hydrogen, fluoro, chloro, bromo, methyl, ethyl, isopropyl, pentyl, hexyl, octyl, methoxy, phenoxy, (4-nitrophenyl)sulfonyl, piperidin-4-yl, or piperazin-1-yl; R4 is hydrogen, chloro, methyl or trifluoromethyl, phenoxy, (4-nitrophenyl)sulfonyl or piperidin-4-yl; or R3 and R4, together with the carbons to which they are attached, form a fused ring selected form the group consisting of: n is 1 or 2. These compounds according to the present invention remarkably inhibits activity of DRAK that inhibits signal systems of TGF-?, which is known to suppress cancer growth, and thus the novel pyrimidine compounds can be used as a pharmaceutical composition for preventing or treating cancer and can be used as a pharmaceutical composition for preventing or treating inflammatory disease.
