A highly sensitive flow injection-chemiluminescence detection (FI-CL) method based on pyrogallol (Pg) chemiluminescent reagent (CLreagent) oxidized by periodate for the determination of propranolol is presented. The presented method is an indirect CL detection method based on the CL emission generated during the oxidation of Pg with the excess of periodate that remains after oxidation of propra...

Xanthomonas citri subsp citri (Xcc) is responsible for one of the most destructive diseases of citrus fruits, Asiatic citrus canker. Based on the bacterial host range, the pathogenic forms, A, A*, and Aw have been identified. A*-type strains are not well characterized and they have been reported to differ from other A-type strains on the basis of biochemical and genetic characteristics. In this...

Antioxidant activity of Berry (Morus alba var. nigra) was investigated. For superoxide anion radical assay, the superoxide anion radicals were generated by a pyrogallol auto oxidation system, Nitric oxide radical inhibition by the use of Griess Illosvoy reaction and reducing power was determined according to the Oyaizu method. At least this sample was represented a potential antioxidant capacit...

The isofunctional enzymes of catechol 1,2-dioxygenase from species of Acinetobacter, Pseudomonas, Nocardia, Alcaligenes, and Corynebacterium oxidize 3-methylcatechol according to both the intradiol and extradiol cleavage patterns. However, the enzyme preparations from Brevibacterium and Arthrobacter have only the intradiol cleavage activity. Comparison of substrate specificity among these isofu...

Nearly 1% of all clinically used drugs are catecholics, a family of catechol-containing compounds. Using label-free dynamic mass redistribution and Tango β-arrestin translocation assays, we show that several catecholics, including benserazide, catechol, 3-methoxycatechol, pyrogallol, (+)-taxifolin and fenoldopam, display agonistic activity against GPR35.
