Definitions
- the invention relates to a serine protease inhibitor having an acylguanidine side chain, a pharmaceutical composition containing the same, as well as the use of said inhibitor for treating and preventing thrombin-related diseases.
- Serine proteases are enzymes which, amongst other things, play an important role in the blood coagulation cascade.
- Members of this group of proteases are for example thrombin, trypsin, factors Vila, IXa, Xa, XIa, X la, and protein C.
- thrombin is the serine protease which regulates the last step in the coagulation cascade.
- the prime function of thrombin is the cleavage of fibrinogen to generate fibrin monomers, which form an insoluble gel by cross-linking.
- thrombin regulates its own production by activating factors V and VIII earlier in the cascade.
- thrombin has important actions at cellular level, where it acts on specific receptors to cause platelet aggregation, endothelial cell activation and fibroblast proliferation.
- thrombin has a central regulatory role in haemostasis and thrombus formation. Since inhibitors of thrombin may have a wide range of therapeutical applications, extensive research has been performed in this area. In the development of synthetic inhibitors of serine proteases, and more specifically of thrombin, the interest in small synthetic peptides that are recognized by proteolytic enzymes in a manner similar to that of natural substrates, has increased.
- thrombin transition state inhibitors of thrombin and the low molecular weight thrombin inhibitor Inogatran (Thromb. Haemostas. 1995, 73: 1325 (Abs. 1633); WO 93/1 1 152 (Example 67)), which has been disclosed to be a potent and selective thrombin inhibitor.
- Related compounds are described in WO 95/23609; in comparison with Inogatran and its analogs, compounds disclosed in this patent application have an aromatic group in the agmatine-like group.

- One vial S-2238 (25 mg, Kabi Diagnostica, Sweden) is dissolved in 20 ml TN buffer to give a concentration of 1 25 mg-ml "1 (2 mmolT 1 ) 4 Thrombin solution Human thrombin (16 000 nKat-vial "1 ; Centraal Laboratorium voor Bloedtransfusie, Amsterdam, The Netherlands) is dissolved in TNP buffer to give a stock solution of 835 nKat-ml '1 . Immediately before use this solution is diluted with TNP buffer to give a concentration of 3.34 nKat-ml "1
- test and reference compounds are dissolved in Milli-Q water to give stock concentrations of IO "2 mol-r 1 Each concentration is stepwise diluted with the vehicle to give concentrations of IO "3 , I O "4 and 10 "5 mol 1
- the dilutions, including the stock solution, are used in the assay (final concentrations in the reaction mixture 3- 10 '3 , 3- 10 "4 , IO “4 , 3- 10 "5 , IO “5 , 3-10 “ * and IO "6 mol-r 1 , respectively)
- test compound or reference compound solutions or vehicle are alternately pipetted into the wells of a microtiter plate and these solutions are diluted with 0 1 15 ml and 0 0165 ml TNP buffer, respectively
- An aliquot of 0 030 ml S-2238 solution is added to each well and the plate is pre-heated and pre-incubated with shaking in an incubator (Amersham) for 10 min at 37 °C
- the hydrolysis of S-2238 is started by addition of 0 030 ml thrombin solution to each well
- the plate is incubated (with shaking for 30 s) at 37 °C Starting after 1 min of incubation, the absorbance of each sample at 405 nm is measured every 2 min for a period of 90 min. using a kinetic microtiter plate reader (Twinreader plus, Flow Laboratories)
