متن کاملElectrochemistry of Deferiprone as an Orally Active Iron Chelator and HIV-1 Replication Inhibitor and its Determination
O comportamento eletroquímico da deferiprona, droga anti-talassêmica e anti-replicação do HIV foi investigado, por voltametria cíclica (VC), utilizando um eletrodo de platina. Observaram-se dois picos anódicos irreversíveis para a deferiprona, em tampão acetato (pH 4,0) com E 0 1 = 875 mV e E 0 2 = 1235 mV (vs. Ag/AgCl) em velocidade de varredura de 50 mV s. Os estudos de voltametria cíclica in...

The effects of two herbivorous insects, Galerucella calmariensis Duftschmid and Myzus lythri L. (Coleoptera: Chrysomelidae), feeding on purple loosestrife, Lythrum salicaria L. (Myrtiflorae: Lythraceae), were measured in the presence of two insect predators, Harmonia axyridis Pallas (Coleoptera: Coccinellidae) and Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae).

متن کاملIdentification of a Histidine Metal Ligand in the <em>argE</em>-Encoded <em>N</em>-Acetyl-L-Ornithine Deacetylase from <em>Escherichia coli</em>
The H355A, H355K, H80A, and H80K mutant enzymes of the argE-encoded N-acetyl-L-ornithine deacetylase (ArgE) from Escherichia coli were prepared, however, only the H355A enzyme was found to be soluble. Kinetic analysis of the Co(II)-loaded H355A exhibited activity levels that were 380-fold less than Co(II)-loaded WT ArgE. Electronic absorption spectra of Co(II)-loaded H355A-ArgE indicate that th...
