MedKoo Cat#: 207014 | Name: Tamnorzatinib
Featured

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Tamnorzatinib, also known as ONO-7475, is a potent and orally active Axl/Mer inhibitor. ONO-7475 targets and binds to both Axl and Mer, and prevents their activity. This blocks Axl- and Mer-mediated signal transduction pathways, and inhibits proliferation and migration of Axl- and Mer-overexpressing tumor cells. Axl and Mer, both members of the TAM (Tyro3, Axl and Mer) family of RTKs, are overexpressed by many tumor cell types. They play key roles in tumor cell proliferation, survival, invasion, angiogenesis and metastasis, and their expression is associated with drug resistance and poor prognosis

Biological target:
Tamnorzatinib (ONO-7475) is a potent, selective, and orally active Axl/Mer inhibitor with IC50 values of 0.7 nM and 1.0 nM.
In vitro activity:
The specific Anexelekto/MER Tyrosine Kinase (AXL) inhibitor, ONO-7475, kills FLT3-mutant AML cells with targets including Extracellular- signal Regulated Kinase (ERK) and Myeloid Cell Leukemia 1 (MCL1). ONO-7475 is effective against ABT-199-resistant cells including cells that overexpress MCL1. Proteomic analyses revealed that ABT-199-resistant cells expressed elevated levels of pro-growth and anti-apoptotic proteins compared to parental cells, and that ONO-7475 reduced the expression of these proteins in both the parental and ABT-199-resistant cells. Reference: Haematologica. 2022 Jun 1;107(6):1311-1322. https://pubmed.ncbi.nlm.nih.gov/34732043/
In vivo activity:
Importantly, ONO-7475 was effective in a human FMS-like tyrosine kinase 3 with internal tandem duplication mutant murine xenograft model. Mice fed a diet containing ONO-7475 exhibited significantly longer survival and, interestingly, blocked leukemia cell infiltration in the liver. In summary, ONO-7475 effectively kills acute myeloid leukemia cells in vitro and in vivo by mechanisms that involve disruption of diverse survival and proliferation pathways.

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
