5-((3-Chlorophenyl)amino)benzo[c][2,6]naphthyridine-8-carboxylic acid (cas: 1009820-21-6) belongs to naphthyridine derivatives. The naphthyridines have 10 delocalized π-electrons located in five molecular orbitals, each of which is distorted by the presence of the nitrogen atoms causing an electron drift in that direction. Transition metal complexes of 1,5-naphthyridine (1,5-napy) seems to form one-dimensional coordination polymers with the ligand acting as bidentate in a “stepped” bridging fashion.Application In Synthesis of 5-((3-Chlorophenyl)amino)benzo[c][2,6]naphthyridine-8-carboxylic acid

A major limitation of targeted cancer therapy is the rapid emergence of drug resistance, which often arises through mutations at or downstream of the drug target or through intrinsic resistance of subpopulations of tumor cells. To find new drug targets and therapeutics for MB that may be less susceptible to common resistance mechanisms, we used a developmental phosphoproteomics approach in murine granule neuron precursors (GNPs), the developmental cell of origin of MB. The protein kinase CK2 emerged as a driver of hundreds of phosphorylation events during the proliferative, MB-like stage of GNP growth, including the phosphorylation of three of the eight proteins commonly amplified in MB. CK2 was critical to the stabilization and activity of the transcription factor GLI2, a late downstream effector in SHH signaling. CK2 inhibitors decreased the viability of primary SHH-type MB patient cells in culture and blocked the growth of murine MB tumors that were resistant to currently available Hh inhibitors, thereby extending the survival of tumor-bearing mice. Because of structural interactions, one CK2 inhibitor (CX-4945) inhibited both wild-type and mutant CK2, indicating that this drug may avoid at least one common mode of acquired resistance. These findings suggest that CK2 inhibitors may be effective for treating patients with MB and show how phosphoproteomics may be used to gain insight into developmental biol. and pathol. In the experiment, the researchers used many compounds, for example, 5-((3-Chlorophenyl)amino)benzo[c][2,6]naphthyridine-8-carboxylic acid (cas: 1009820-21-6Application In Synthesis of 5-((3-Chlorophenyl)amino)benzo[c][2,6]naphthyridine-8-carboxylic acid).
