-
Paragraph 0216; 0246-0248, (2018/07/31)
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.

Novel 3,6-disubstituted pyridazines were synthesized by facile method and screened for their vasorelaxant properties utilizing isolated thoracic rat aortic rings. Compounds 8a and 11a exerted potent vasorelaxant activity (IC50 = 198 and 177 μM, respectively) relative to doxazosin mesylate (used reference standard, IC50 = 226 μM), that, they may represent promising hits for treatment of cardiovascular disorders. The observed activity was validated by a statistically significant QSAR model (N = 32, n = 6, R2 = 0.811782, R2cvOO = 0.7153, R2cvMO = 0.7209, F = 17.9708, s2 = 9.65226 × 10-8) that was obtained employing CODESSA-Pro software.

An easily available Pd(OAc)2/(2-mesitylindenyl) dicyclohexylphosphine/Me(octyl)3N+Cl-/K 3PO4·3H2O catalytic system was developed and it shows high catalytic activity in the Suzuki-Miyaura cross-coupling reaction of a diverse array of aryl and heteroaryl chlorides in water. Notably, this catalytic system also works with ultra-low loading of the catalyst with high turnover numbers.
