Abstract: Protein kinase CK2 plays multiple roles in cell function in normal and disease states. CK2 is elevated in numerous types of cancer cells, and CK2 suppression of apoptosis represents a key link to the cancer cell phenotype. CK2 regulation of cell survival and death involves diverse processes, and our previous work suggested that mitochondrial machinery is a key locus of this function. One of the earliest responses of prostate cells to inhibition of CK2 is a change in mitochondrial membrane potential, possibly associated with Ca2+ signaling. PCa cells were treated with the CK2 small mol. inhibitors 4,5,6,7-tetrabrombenzotriazole and CX-4945 followed by anal. of Ca2+ levels in various cellular compartments over time. The results showed dose-dependent loss in cytosolic Ca2+ levels starting within 2 min and reaching maximal loss within 5-10 min. The results suggest that inhibition of CK2 activity results in a rapid movement of Ca2+ out of the cytosol and into the ER and mitochondria, which may be among the earliest contributory factors for induction of apoptosis in cells subjected to inhibition of CK2. In cells with death-inducing levels of CK2 inhibition, total cellular Ca2+ levels dropped at 2 h post-treatment. These novel observations represent a potential mechanism underlying regulation of cell survival and death by CK2 activity. In the experiment, the researchers used many compounds, for example, 5-((3-Chlorophenyl)amino)benzo[c][2,6]naphthyridine-8-carboxylic acid (cas: 1009820-21-6Quality Control of 5-((3-Chlorophenyl)amino)benzo[c][2,6]naphthyridine-8-carboxylic acid).
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. Halogen atoms attached to the naphthyridine moiety can be easily replaced by other nucleophiles such as alkoxides and amines.Quality Control of 5-((3-Chlorophenyl)amino)benzo[c][2,6]naphthyridine-8-carboxylic acid
