Reference of 50551-63-8, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 50551-63-8, molcular formula is C9H8O2, introducing its new discovery.
In the present work we report the synthesis of four new ER ligands which can be used as scaffolds for the introduction of the basic side chains necessary for antiestrogenic activity. Affinities and agonist/antagonist characterization of the ligands for both ERalpha and ERbeta have been determined in a competitive radioligand assay, and in an in vitro coactivator recruitment functional assay, respectively. Molecular modelling techniques have been used in order to rationalize the experimental results. Compound 2 is reported as a novel ERbeta-agonist/ERalpha-antagonist. Two compounds show an interesting antitumour profile towards two pancreatic cancer cell lines and have been selected for in vivo assays.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 50551-63-8 is helpful to your research. Reference of 50551-63-8
