And the article contained the following:

The mitochondrial pool of Hsp90 and its mitochondrial paralog, TRAP1, suppresses cell death and reprograms energy metabolism in cancer cells; therefore, Hsp90 and TRAP1 have been suggested as target proteins for anticancer drug development. Here, the authors report that the actual target protein in cancer cell mitochondria is TRAP1, and current Hsp90 inhibitors cannot effectively inactivate TRAP1 because of their insufficient accumulation in the mitochondria. To develop mitochondrial TRAP1 inhibitors, the authors determined the crystal structures of human TRAP1 complexed with Hsp90 inhibitors. The iso-Pr amine of the Hsp90 inhibitor PU-H71 was replaced with the mitochondria-targeting moiety triphenylphosphonium to produce SMTIN-P01. SMTIN-P01 showed a different mode of action from the nontargeted PU-H71, as well as much improved cytotoxicity to cancer cells. In addition, the authors determined the structure of a TRAP1-adenylyl-imidodiphosphate (AMP-PNP) complex. On the basis of comparative anal. of TRAP1 structures, the authors propose a mol. mechanism of ATP hydrolysis that is crucial for chaperone function. The experimental process involved the reaction of (6-Bromohexyl)triphenylphosphonium bromide(cas: 83152-22-1).Formula: C24H27Br2P

Kreyenschmidt, Friedrich; Koszinowski, Konrad published an article in 2018, the title of the article was Low-Valent Ate Complexes Formed in Cobalt-Catalyzed Cross-Coupling Reactions with 1,3-Dienes as Additives.Related Products of 83152-22-1 And the article contains the following content:

The combination of CoCl2 and 1,3-dienes is known to catalyze challenging alkyl-alkyl cross-coupling reactions between Grignard reagents and alkyl halides, but the mechanism of these valuable transformations remains speculative. Herein, electrospray-ionization mass spectrometry is used to identify and characterize the elusive intermediates of these and related reactions. The vast majority of detected species contain low-valent cobalt(I) centers and diene mols. Charge tagging, deuterium labeling, and gas-phase fragmentation experiments elucidate the likely origin of these species and show that the diene not only binds to Co as a π ligand, but also undergoes migratory insertion reactions into Co-H and Co-R bonds. The resulting species have a strong tendency to form anionic cobalt(I) ate complexes, the superior nucleophilicity of which should render them highly reactive toward electrophilic substrates and, thus, presumably is the key to the high catalytic efficiency of the system under investigation. Upon the reaction of the in situ formed cobalt(I) ate complexes with organyl halides, only the final cross-coupling product could be detected, but no cobalt(III) species. This finding implies that this reaction step proceeds in a direct manner without any intermediate or, alternatively, that it involves an intermediate with a very short lifetime. The experimental process involved the reaction of (6-Bromohexyl)triphenylphosphonium bromide(cas: 83152-22-1).Related Products of 83152-22-1

Islam, M. Q.; Hill, W. E.; Webb, T. R. published an article in 1989, the title of the article was Synthesis and characterization of long chain unsymmetrical diphosphines.Safety of (6-Bromohexyl)triphenylphosphonium bromide And the article contains the following content:

The long-chain unsym. diphosphines, R2P(CH2)nPPh2 (R = Me, Et; n = 6, 8) have been synthesized and characterized by their 31P and 1H NMR spectra. The purity of product is strictly dependent on the reaction condition. Attempted preparation of the diphosphines with same substituents on P but a longer chain length (10 and 12 methylene bridge) was unsuccessful because of possible disubstitution in the first of the four step synthesis giving mixed products (sym. and unsym. diphosphines). The experimental process involved the reaction of (6-Bromohexyl)triphenylphosphonium bromide(cas: 83152-22-1).Safety of (6-Bromohexyl)triphenylphosphonium bromide

On June 11, 2020, Sunwoo, Kyoung; Won, Miae; Ko, Kyung-Phil; Choi, Miri; Arambula, Jonathan F.; Chi, Sung-Gil; Sessler, Jonathan L.; Verwilst, Peter; Kim, Jong Seung published an article.Electric Literature of 83152-22-1 The title of the article was Mitochondrial Relocation of a Common Synthetic Antibiotic: A Non-genotoxic Approach to Cancer Therapy. And the article contained the following:

Tumor recurrence as a result of therapy-induced nuclear DNA lesions is a major issue in cancer treatment. Currently, only a few examples of potentially non-genotoxic drugs have been reported. Mitochondrial re-localization of ciprofloxacin, one of the most commonly prescribed synthetic antibiotics, is reported here as a new approach. Conjugation of ciprofloxacin to a tri-Ph phosphonium group (giving lead Mt-CFX) is used to enhance the concentration of ciprofloxacin in the mitochondria of cancer cells. The localization of Mt-CFX to the mitochondria induces oxidative damage to proteins, mtDNA, and lipids. A large bias in favor of mtDNA damage over nDNA was seen with Mt-CFX, contrary to classic cancer chemotherapeutics. Mt-CFX was found to reduce cancer growth in a xenograft mouse model and proved to be well tolerated. Mitochondrial re-localization of antibiotics could emerge as a useful approach to generating anticancer leads that promote cell death via the selective induction of mitochondrially mediated oxidative damage. The experimental process involved the reaction of (6-Bromohexyl)triphenylphosphonium bromide(cas: 83152-22-1).Electric Literature of 83152-22-1
