A series of benzofuran derivatives were designed and synthesized, and their inhibitory activites were measured against the SIRT1-3. The enzymatic assay showed that all the compounds showed certain anti-SIRT2 activity and selective over SIRT1 and SIRT3 with IC50 (half maximal inhibitory concentration) values at the micromolar level. The preliminary structure-activity relationships were analyzed ...
The objective of this pilot study was to compare the different ways of measuring salivary alpha-amylase (sAA, enzymatic vs. concentration) and to evaluate the influence that the different ways of reporting the results can have in sAA interpretation. For this purpose, sAA was measured by direct quantification and also by an enzymatic assay in three different naturalistic situations, a physical s...
We developed a continuous spectrofluorimetric assay of lysoplasmalogenase activity with the use of horse liver alcohol dehydrogenase as a coupling enzyme. In this method the disappearance of NADH is measured spectrofluorimetrically. The excitation and emission monochromators were set at 340 and 460 nm respectively. The assay is 10 times as sensitive as the previous u.v. spectrophotometric metho...
BACKGROUND Urinary creatinine can be quantified by Jaffe or enzymatic assays and is commonly used as denominator of urinary excretion of electrolytes or protein. Paired analysis in pediatric and adult samples documented inter-assay differences (up to 80%). We verified the interchangeability of two IDMS-traceable assays (Jaffe and enzymatic) for neonatal urine and report on neonatal urinary crea...
