AZ14145845
Based on 1 Customer Validation
AZ14145845 is an orally active dual-target type 1½ kinase inhibitor of Mer/Axl, which inhibits Mer kinase (pIC50 = 9.0) and Axl kinase (pIC50 = 7.9) with high selectivity over Flt3 and Tyro3. AZ14145845 suppresses Mer- and Axl-dependent proliferation in Ba/F3 cells and inhibits efferocytosis in macrophages. AZ14145845 reduces the phagocytosis of photoreceptor outer segments by polarized human retinal epithelial cells. AZ14145845 inhibits tumor growth and induces tumor regression in vivo, and its combination with anti-PD1 antibody and ionizing radiation improves the survival rate of mice with colorectal cancer. AZ14145845 causes retinal degeneration in mice, with pathological changes similar to those in MERTK loss-of-function models. AZ14145845 can be used in studies related to retinal degeneration, lymphoma and colorectal cancer.

AZ14145845 (1 h) potently inhibits intracellular Mer activity (pIC50 = 7.8) and weakly inhibits intracellular Axl activity (pIC50 = 7.0) in transfected COS-7 cells, with no activity against intracellular Flt3 or Tyro3[2].

-
Dosage:200 mg/kg
-
Administration:p.o.; twice daily; 28 days
-
Result:Reached quantified concentrations of ~9 µM in the posterior eye region, ~11 µM in the anterior eye region, and ~3 µM in the whole eye.
Induced retinal lesions consistent with atrophy in 4 of 8 treated animals, including marked thinning of the outer nuclear layer, loss of photoreceptors, flattening of RPE cells with loss of apical microvilli, and occasional pyknotic ONL nuclei.
Caused ultrastructural changes including disorganized photoreceptor outer segments at the RPE-POS interface, loss of association between RPE microvilli and POS, and a disorganized debris zone of fragmented discs and microvilli.
Led to diffuse retinal degeneration affecting the entire retina length in one treated animal, and focal lesions affecting 20-25% of the retina length in three animals.
