Reference of 22876-22-8, 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, 22876-22-8, molcular formula is C8H7NOS, introducing its new discovery.
2-sulfinyl benzothiazoles, -oxazoles and -imidazoles are novel in vitro bone anti-reabsorptive compounds
Bone resorption by osteoclasts is dependent on H+ transport into the external resorption lacunae, generating an acidic microenvironment in which bone mineral dissolution and matrix degradation occur. A vacuolar H+-ATPase is responsible for osteoclast H+ secretion. Here, we describe novel vacuolar H+-ATPase inhibitors that inhibit bone resorption in vitro. Several agents inhibited 45Ca release from mouse calvariae, 3H-proline release from bone particles by chicken osteoclast-like cells, and resorption pit formation by murine osteoclasts on dentine slices. One compound, a 2-sulfinylbenzothiazole (XS238), is significantly more potent than previously reported vacuolar H+-ATPase inhibitors, exhibiting an IC50 of 5 muM in the 45Ca release assay, an IC50 of 1 muM in the 3H-proline release assay, and an IC50 of 100 nM in the resorption pit assay. The potent H+-ATPase inhibitors described may have value in treating osteoporosis and other bone diseases.
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 22876-22-8 is helpful to your research. Reference of 22876-22-8
