In this equation, Y is the ratio of residual thrombin activity in the presence of inhibitor to that in its absence (fractional residual activity), YM and YO are the maximum and minimum possible values of the fractional residual proteinase activity, IC50 is the concentration of the inhibitor that results in 50% inhibition of enzyme activity, and HS is the Hill Slope, which was set constant at 1. A current version of SigmaPlot (SPSS, Inc. Chicago, IL) was used to perform non-linear curve fitting in which YM, YO and IC50 were allowed to float.

Most cited protocols related to «Benzofurans»
To measure the extracts 1O2 quenching capacity a competition reaction was carried out using endoperoxide (EP, Invitrotech, Kyoto, Japan) as a singlet oxygen generator and 2,5-diphenyl- 3,4-benzofuran (DPBF, Sigma–Aldrich, Barcelona, Spain) as an UV-Vis absorption probe in a 96-well quartz glass microplate. In each well, 15 µL of the peel extract was mixed with 150 µL of DPBF (0.8 mM solution) and 75 µL of EP (1 mM). The microplate was loaded in dim light and on an ice bath. Absorbance changes of DPBF at 413 nm were monitored during a 90 min reaction at 35 °C using a UV-Vis spectrophotometer microplate reader (SPECTROstar® Omega, BMG Labtech, Offenburg, Germany). α-tocopherol (Sigma–Aldrich, Barcelona, Spain) was used as a standard compound and ethanol:chloroform:water (50:50:1, v:v:v) as a blank. The relative SOAC value for each sample was calculated with the following Formula (2):
Each sample was replicated in 3 wells, and the assay was replicated twice. Results were the mean of the replicates in the 2 microplates (mean ± SE).
