Related Products of 591-54-8. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 4-Aminopyrimidine, is researched, Molecular C4H5N3, CAS is 591-54-8, about Recent developments of RET protein kinase inhibitors with diverse scaffolds as hinge binders. Author is Jia, Cong-Cong; Chen, Wang; Feng, Zi-Li; Liu, Zhao-Peng.
A review. RET is a proto-oncogene encoding a receptor tyrosine kinase. RET regulates key aspects of cellular proliferation, differentiation and survival. The activation of RET via gene fusions or point mutations is closely related to lung, thyroid and other cancers. This review summarizes the developments of a diversity of small mol. RET protein kinase inhibitors in the past 10 years. These RET inhibitors are classified according to their hinge binder chemotypes as: pyrimidines, including the pyrazolopyrimidines, pyrimidine oxazines, quinazolines, 4-aminopyrimidines and 4-aminopyridines; indolinones; 5-aminopyrazole-4-carboxamides; 3-trifluoromethylanilines; imidazopyridines, imidazopyridazines and pyrazopyridines; nicotinonitriles; pyridones and 1,2,4-triazoles. In each section, the biol. activities of the inhibitors, their structure-activity relationships and possible binding modes with the RET kinase are introduced.
