In humans, polymorphic N-acetyltransferases NAT1 and NAT2 are important enzymes that metabolize endogenous and exogenous compounds, including drugs. These enzymes exhibit considerable inter-individual variability in humans. The cynomolgus macaque is a nonhuman primate species that is widely used in drug

Benzoic acid and pyridine derivatives inhibit recombinant trans-sialidase from Trypanosoma cruzi with I50 values between 0.4 and 1mM. The best compounds, 4-acetylamino-3-hydroxymethylbenzoic acid and 5-acetylamino-6-aminopyridine-2-carboxylic acid, provide new leads to inhibitors not containing the synthetically complex sialic acid structure. The

We have previously reported that human lymphoid cells, such as peripheral blood mononuclear leukocytes (PBML) and the T-cell leukemia line Jurcat, synthesize p-acetamidobenzoic acid from p-aminobenzoic acid (PABA) and a two carbon fragment from arachidonic acid (AA), conceivably derived from

We characterize here an arachidonic acid (AA)-derived metabolite previously found to have an adjuvant effect in phytohemagglutinin-induced mitogenesis of lymphocytes from mothers of newborn babies and from immunodeficient infants. We named the metabolite 'compound 4' due to its position in

p-Aminobenzoic acid (PABA), p-acetamidobenzoic acid (PADB) and p-aminohippuric acid (PAH) have been separated and determined by a reversed phase, isocratic high performance liquid chromatographic (HPLC) procedure simultaneously. The mobile phase, at 1.5 ml min-1, used was 10 mM sodium hydrogen
