(3127) Pharmacological Activities
(3128) The compounds of the present invention possess Factor XIa inhibitory activity and oral bioavailability, for example, such an effect of the compounds of the present invention was confirmed by the following tests.
(3129) All the procedures were conducted by conventionally used techniques on the basis of basic biological methods. Furthermore, the measuring method of the present invention was modified to improve the accuracy and/or sensitivity of measurement for evaluating the compound of the present invention. The detailed experimental method was as follows.
(3130) Experimental Method
(3131) (1) In Vitro Assay
(3132) Inhibitory activities of compounds of the present invention against factor XIa, Xa, XIIa, IXa, VIIa, plasma kallikrein or thrombin were evaluated using appropriate purified proteases and synthetic substrates. The rate of hydrolysis of the chromogenic substrate by the relevant protease was continuously measured at 405 nm.
(3133) Inhibitory activity against each enzyme was calculated as % inhibition using the equation described below.
% Inhibition=[[(rate without compound)−(rate with compound)](rate without compound)]×100%.
Each half maximal inhibitory concentration (IC.sub.50) value was determined by plotting the concentration of compound of the invention against the % inhibition.
