Towards dual inhibitors of the MET kinase and WNT signaling pathway; Design, synthesis and biological evaluation

Both the kinase MET and the WNT signaling pathway are attractive targets in cancer therapy, and synergistic effects have previously been observed in animal models upon simultaneous inhibition. A strategy towards a designed multiple ligand of MET and WNT signaling is pursued based on the two hetero biaryl systems present in both the MET inhibitor tepotinib and WNT signaling inhibitor TC-E 5001. Initial screening was conducted to find the most suitable ring systems for further optimization, whereas a second screen explored modifications towards pyridazinones and triazolo pyridazines. Up to 54% reduction of WNT signaling activity at 10 μM concentration was achieved, however, only low affinities towards MET were observed. Overall, the thiophene substituted pyridazinone 40 was the best dual MET and WNT signaling inhibitor, with a 17% and 19% reduction of activity, respectively. Although further optimizations are needed to achieve more potent dual inhibitors, the strategy presented herein can be valuable towards the development of a dual inhibitor of MET and WNT signaling.

Novel Hydrazinone-substituted Pyrimidine Derivatives and Use Thereof

The present invention relates to a pyrimidine derivative substituted with novel hydrazine or a pharmaceutically acceptable salt thereof, and to a pharmaceutical composition for inhibiting c-Met tyrosine kinase activity and to a pharmaceutical composition for preventing or treating hyperproliferative disorders, which comprise same as an active ingredient. The present invention can be effectively used as a treatment agent for various hyperproliferative disorders related to excessive cell proliferation and growth caused by abnormal kinase activity, such as cancer, psoriasis, rheumatoid arthritis, and diabetic retinopathy by efficiently inhibiting c-Met tyrosine kinase activity.

Novel Triazolo Pyridazine Derivatives and Use Thereof

The present invention relates to a novel triazolo pyridazine derivative or a pharmaceutically acceptable salt thereof, to a pharmaceutical composition for inhibiting c-Met tyrosine kinase activity and a pharmaceutical composition for preventing or treating an abnormal proliferation disorder (hyperproliferative disorder) comprising same as an active ingredient, and to a method for preventing or treating an abnormal proliferation disorder (hyperproliferative disorder) comprising a step of administering a pharmaceutically effective amount of the pharmaceutical composition to a subject in need thereof. The present invention can advantageously be used as a therapeutic agent for various abnormal proliferation disorders such as cancer, psoriasis, rheumatoid arthritis and diabetic retinopathy which are associated with excessive cell proliferation and growth due to irregular kinase activity by effectively suppressing the activity of c-Met tyrosine kinase.
