Uptake and inhibition studies were carried out in 24-well poly-D-lysine-coated plates with the cells 48 h after transfection. Before use, the transfected cells were functionally characterized with para-aminohippuric acid (a substrate for Oat1 and OAT1), prostaglandin F2α (a substrate for Oat...
The precursor molecule, phenazine-1-carboxylic acid (PCA)4 (Fig. 1), is synthesized from chorismic acid by enzymes encoded in the homologous phzABCDEFG1 and phzABCDEFG2 operons (21, 22). Additional enzymes catalyze structural modifications of PCA to pyocyanin, phenazine-1-hydroxide, and ...
Novel prepn. of phosphorous acid diesters (I) is by reacting either H3PO4 or a phosphorous acid monoester R2OPH(O)OH (II) with a carboxylic acid anhydride (III) and an alcohol R2OH (IV) at 20-50 deg. C, with the H2PO4 or (II) being first mixed with (III) and (IV) then ...
