Back~ro1~nd of the Invention Thrombin plays several criticaI roles in 20 hemostasis, the normal physiological process by which bleeding from an injured blood vesse' is arrested.
Thrombin cleaves soluble fibrinogen to form insoluble fibrin in the last proteolytic step of botk the e~:trinsic and intrinsic pathways of the coagulation
2~ cascade. Fibrin may be further insolubilized through crosslinking by the thrombin-activated enzyme, factor XIIIa. In addition, thrombin-induced activation of platelets leads to their aggregation and the secretion of additional factors that further accelerate creation 30 of a hemostatic plug. Thrombin also potentiates its own production by the activation of factors V and VIII.
Recent reviews of the roles of thrombin in coagulation have been reported by E enton in Ann. N. Y. Acad. Sci .

Ut; lity The compounds of formula (I) are useful as inhibitors of serine proteases and notably human thrombin, plasma kallikrein and plasmin. Because of their inhibitory action, these compounds are indic~ted for use in the preYention or treatment of physiologica' , reactions, blood coagulatiQn and inflammatior., calalyzed b~ the aforesaid class of er.zymes.
Inhibition constants were determined by the melhod described by Kettner et al. in J. ~iol. ~hem. 265, 18289-18297 (1990~, herein incorporated by reference.
In these assays, thrombin-mediated hydrolysis cf the chromogenic substrate S2238 (Helena Laboratories, Beaumont, TX) was monitored spectrophotometrically.
Aad~ tion of an inhibitor to the assay miY.Iure resul~s lr ~- decreased absorbance and is indicative of thrombin inhibition. Human thrombin (Enzyme Research Laboratories, Inc., South Bend, Il~ al a concentratior.
of 0.2 nM in 0.10 M sodium phosphate buffer, pH 7.S, 0.20 ~ NaCl, and 0 S'i polyethylene glycol 6000, was ~0 incubated with various substrate concentrations ranging from 0.20 to 0.02 mM. After 25 to 30 minuteS of ~
incubation, thrombin activity was assayed by moni1:0rins the rate of increase in absorbance at 9405 nm which arises owing to substrate hydrolysis. Inhibition constants were derived from reciprocal plots of tbe 1 ~
~ WO9~1098S9 21 7~31`~. PCr/U594/11049 re~ction velocity as a function of substrate concentration using the standard method of Lineweaver and Burk.
Using the methodology described above, 5 representative compounds of this invention were evaluated and found to exhib t a Ki of less than l mM, thereby confirming the utility of the compounds of the invention as effective thrombin inhibitors.
The ability of the compounds to inhibit coagulation lO was assayed in normal rabbit piasma which was prepared by diluting blood l:lO with 3.2~ aqueous citric acid followed by centrifugation. Bovine thrombin was obtained from Sigma and diluted to 2~ NIH units/mL.
Plasma ( 0.2 mL) and buffe~ (0.05 m~, O.lO M
l~ ~ris[hydroxymethyl~-aminomethane hydrochloride, pH 7.4, o . 9~ (w/v) sodium chloride, and 2 . 5 mg/mL bovine serum albumin) containing inhibitor were incubated 3 min at 37 C in a fibrameter. Reactions were ~initiated by adding thrombin (0.05 mL) T:O achieve a final concentration of 4 20 NIH units/mL. ~he effectiveness of compounds as antiGoagulants is reported as the level of inhibitor req~ired to prolong clotting to that observed for 2 NIH
units/mL of .thrombin in the absence of inhibitor. In this assay then, better inhibitors req~ire lower 2~ concentrations to dela~ clot formatlon. Representative compounds of this invention were evaluated and found to be active.
Since the ~ :~.pounds of formula (I) have anti-thromoogeniC proper~ies, they may be employed when an 30 anti-thrombogenic agent is indicated, such as for the control of the coagulation of the fibrinolysis system in mammals or they may be added to blood for the purpose of preventing coagulation of the blood due to contact with blood collecting or distribution 3' containers, tubing or apparatus.
WO9S/09859 ~ 3 1~.; PCr/US94111049 Generally, these compounds may be administered orally, parenterally or intravenousl ~ to a host to obtain an anti-thrombogenic effect. The dosage of the active compound depends on the mammalian species, body 5 weight, age, and mode of administration as determined by one skilled in the art. In the case of large mammals such as humans, the compounds may be administered alone or in combination with pharmaceutical carriers or diluents at a dose of from l0 0.02 to 15 mg/kg to obtain the anti-thrombogenic effect, and may be given as a single dose or in divided doses or as a sustained release formulation.
Pharmaceutical carriers or diluents are well known and include sugars, s~arches and water, which may be used to 15 make tablets, capsules, injectable solutions or the like which can serve as suitable dosage forms for administration of the compounds of this invention.
Rem;nqton's Pharmaceutlcal Sciences, A. Osol, is a standard reference teY.t which discloses sui~able 20 pharmaceutical carriers and dosage forms. The disclosure of this text is hereby incorporated by reference for a more complete teaching of suit:able dosage forms for administration of the compounds of this invention .

Ut; lity The compounds of formula (I) are useful as inhibitors of serine proteases and notably human thrombin, plasma kallikrein and plasmin. Because of their inhibitory action, these compounds are indic~ted for use in the preYention or treatment of physiologica' , reactions, blood coagulatiQn and inflammatior., calalyzed b~ the aforesaid class of er.zymes.
Inhibition constants were determined by the melhod described by Kettner et al. in J. ~iol. ~hem. 265, 18289-18297 (1990~, herein incorporated by reference.
In these assays, thrombin-mediated hydrolysis cf the chromogenic substrate S2238 (Helena Laboratories, Beaumont, TX) was monitored spectrophotometrically.
Aad~ tion of an inhibitor to the assay miY.Iure resul~s lr ~- decreased absorbance and is indicative of thrombin inhibition. Human thrombin (Enzyme Research Laboratories, Inc., South Bend, Il~ al a concentratior.
of 0.2 nM in 0.10 M sodium phosphate buffer, pH 7.S, 0.20 ~ NaCl, and 0 S'i polyethylene glycol 6000, was ~0 incubated with various substrate concentrations ranging from 0.20 to 0.02 mM. After 25 to 30 minuteS of ~
incubation, thrombin activity was assayed by moni1:0rins the rate of increase in absorbance at 9405 nm which arises owing to substrate hydrolysis. Inhibition constants were derived from reciprocal plots of tbe 1 ~
~ WO9~1098S9 21 7~31`~. PCr/U594/11049 re~ction velocity as a function of substrate concentration using the standard method of Lineweaver and Burk.
Using the methodology described above, 5 representative compounds of this invention were evaluated and found to exhib t a Ki of less than l mM, thereby confirming the utility of the compounds of the invention as effective thrombin inhibitors.
The ability of the compounds to inhibit coagulation lO was assayed in normal rabbit piasma which was prepared by diluting blood l:lO with 3.2~ aqueous citric acid followed by centrifugation. Bovine thrombin was obtained from Sigma and diluted to 2~ NIH units/mL.
Plasma ( 0.2 mL) and buffe~ (0.05 m~, O.lO M
l~ ~ris[hydroxymethyl~-aminomethane hydrochloride, pH 7.4, o . 9~ (w/v) sodium chloride, and 2 . 5 mg/mL bovine serum albumin) containing inhibitor were incubated 3 min at 37 C in a fibrameter. Reactions were ~initiated by adding thrombin (0.05 mL) T:O achieve a final concentration of 4 20 NIH units/mL. ~he effectiveness of compounds as antiGoagulants is reported as the level of inhibitor req~ired to prolong clotting to that observed for 2 NIH
units/mL of .thrombin in the absence of inhibitor. In this assay then, better inhibitors req~ire lower 2~ concentrations to dela~ clot formatlon. Representative compounds of this invention were evaluated and found to be active.
Since the ~ :~.pounds of formula (I) have anti-thromoogeniC proper~ies, they may be employed when an 30 anti-thrombogenic agent is indicated, such as for the control of the coagulation of the fibrinolysis system in mammals or they may be added to blood for the purpose of preventing coagulation of the blood due to contact with blood collecting or distribution 3' containers, tubing or apparatus.
WO9S/09859 ~ 3 1~.; PCr/US94111049 Generally, these compounds may be administered orally, parenterally or intravenousl ~ to a host to obtain an anti-thrombogenic effect. The dosage of the active compound depends on the mammalian species, body 5 weight, age, and mode of administration as determined by one skilled in the art. In the case of large mammals such as humans, the compounds may be administered alone or in combination with pharmaceutical carriers or diluents at a dose of from l0 0.02 to 15 mg/kg to obtain the anti-thrombogenic effect, and may be given as a single dose or in divided doses or as a sustained release formulation.
Pharmaceutical carriers or diluents are well known and include sugars, s~arches and water, which may be used to 15 make tablets, capsules, injectable solutions or the like which can serve as suitable dosage forms for administration of the compounds of this invention.
Rem;nqton's Pharmaceutlcal Sciences, A. Osol, is a standard reference teY.t which discloses sui~able 20 pharmaceutical carriers and dosage forms. The disclosure of this text is hereby incorporated by reference for a more complete teaching of suit:able dosage forms for administration of the compounds of this invention .
