PYRAZOLE DERIVATIVES AS PLASMA KALLIKREIN INHIBITORS
This invention relates to enzyme inhibitors that are inhibitors of plasma kallikrein and to pharmaceutical
compositions ning and the uses of, such inhibitors.
Background to the Invention
The heterocyclic derivatives of the present invention are inhibitors of plasma kallikrein and have a
number of therapeutic applications, particularly in the treatment of retinal vascular permeability
associated with diabetic retinopathy and diabetic r edema.
Plasma kallikrein is a trypsin-like serine protease that can liberate kinins from kininogens (see K. D.
Bhoola et al., "Kallikrein-Kinin Cascade", Encyclopedia of Respiratory ne, p483-493; J. W. Bryant et
al., "Human plasma kallikrein-kinin system: physiological and biochemical parameters" Cardiovascular
and haematological agents in medicinal chemistry, 7, p234-250, 2009; K. D. Bhoola et al.,
Pharmacological Rev., 1992, 44, 1; and D. J. Campbell, "Towards understanding the kallikrein-kinin
system: insights from the ement of kinin es", Brazilian Journal of Medical and Biological
Research 2000, 33, 665-677). It is an essential member of the intrinsic blood ation cascade
although its role in this cascade does not involve the release of bradykinin or enzymatic ge.
Plasma prekallikrein is encoded by a single gene and synthesized in the liver. It is secreted by
hepatocytes as an inactive plasma prekallikrein that circulates in plasma as a heterodimer complex
bound to high lar weight kininogen which is activated to give the active plasma kallikrein. Kinins
are potent ors of inflammation that act through G n-coupled ors and antagonists of
kinins (such as bradykinin antagonists) have previously been investigated as potential therapeutic agents
for the treatment of a number of disorders (F. Marceau and D. Regoli, Nature Rev., Drug Discovery,
2004, 3, 845-852).
Plasma kallikrein is thought to play a role in a number of inflammatory disorders. The major inhibitor of
plasma kallikrein is the serpin C1 esterase inhibitor. Patients who present with a genetic deficiency in C1
esterase tor suffer from hereditary angioedema (HAE) which results in intermittent swelling of
face, hands, throat, gastro-intestinal tract and genitals. Blisters formed during acute episodes contain
high levels of plasma kallikrein which cleaves high molecular weight kininogen liberating bradykinin
leading to increased vascular permeability. Treatment with a large protein plasma kallikrein inhibitor has
been shown to effectively treat HAE by preventing the release of bradykinin which causes increased
vascular permeability (A. Lehmann "Ecallantide (DX-88), a plasma rein inhibitor for the treatment
of hereditary angioedema and the tion of blood loss in on-pump thoracic surgery" Expert
Opin. Biol. Ther. 8, p1187-99).
WO 07983
The plasma kallikrein-kinin system is abnormally abundant in patients with advanced diabetic r
edema. It has been recently published that plasma kallikrein contributes to retinal vascular dysfunctions
in diabetic rats (A. Clermont et al. "Plasma rein mediates l vascular ction and induces
l ning in diabetic rats" Diabetes, 2011, 60, p1590-98). Furthermore, administration of the
plasma kallikrein inhibitor ASP-440 rated both retinal vascular bility and retinal blood flow
abnormalities in diabetic rats. Therefore a plasma kallikrein inhibitor should have utility as a treatment
to reduce retinal vascular permeability associated with diabetic retinopathy and diabetic macular
edema.
Plasma kallikrein also plays a role in blood coagulation. The intrinsic coagulation cascade may be
activated by factor XII (FXII). Once FXII is activated (to FXIIa), FXIIa triggers fibrin formation through the
tion of factor XI (FXI) thus resulting in blood coagulation. Plasma kallikrein is a key component in
the intrinsic coagulation e because it activates FXII to FXIIa, thus resulting in the activation of the
intrinsic coagulation pathway. Furthermore, FXIIa also activates further plasma prekallikrein resulting in
plasma kallikrein. This results in positive feedback amplification of the plasma kallikrein system and the
intrinsic coagulation pathway (Tanaka et al. (Thrombosis Research 2004, 113, 333-339); Bird et al.
(Thrombosis and Haemostasis, 2012, 107, 1141-50).
Contact of FXII in the blood with negatively charged surfaces (such as the surfaces of external pipes or
the membrane of the oxygenator that the blood passes during cardiopulmonary bypass surgery) induces
a conformational change in zymogen FXII resulting in a small amount of active FXII (FXIIa). The formation
of FXIIa triggers the formation of plasma kallikrein resulting in blood coagulation, as described above.
tion of FXII to FXIIa can also occur in the body by contact with negatively charged surfaces on
various sources (e.g. bacteria during , RNA from degrading , thus resulting in disseminated
intravascular coagulation (Tanaka et al. (Thrombosis Research 2004, 113, 333-339)).
Therefore, inhibition of plasma rein would inhibit the blood coagulation cascade described above,
and so would be useful in the treatment of disseminated intravascular coagulation and blood
coagulation during cardiopulmonary bypass surgery where blood coagulation is not desired. For
example, Katsuura et al. (Thrombosis Research, 1996, 82, 8) showed that administration of a
plasma rein inhibitor, PKSI-527, for LPS-induced disseminated intravascular coagulation
significantly suppressed the decrease in platelet count and fibrinogen level as well as the se in FDP
level which usually occur in disseminated intravascular coagulation. Bird et al. (Thrombosis and
Haemostasis, 2012, 107, 1141-50) showed that clotting time increased, and thrombosis was significantly
d in plasma kallikrein-deficient mice. Revenko et al. (Blood, 2011, 118, 5302-5311) showed that
the reduction of plasma likrein levels in mice using antisense ucleotide treatment resulted
in rombotic effects. Tanaka et al. (Thrombosis Research 2004, 113, 333-339) showed that
contacting blood with DX-88 (a plasma kallikrein inhibitor) resulted in an increase in activated clotting
time (ACT). Lehmann et al. (Expert Opin. Biol. Ther. 2008, 1187-99) showed that Ecallantide (a plasma
kallikrein inhibitor) was found to delay contact activated induced coagulation. Lehmann et al. de
that ntide ”had in vitro anticoagulant effects as it ted the intrinsic y of coagulation by
inhibiting plasma kallikrein”.
Plasma rein also plays a role in the inhibition of platelet activation, and therefore the cessation of
bleeding. et activation is one of the earliest steps in hemostasis, which leads to platelet plug
formation and the rapid cessation of bleeding following damage to blood vessels. At the site of vascular
injury, the interaction between the exposed collagen and ets is critical for the retention and
activation of platelets, and the subsequent cessation of bleeding.
Once activated, plasma kallikrein binds to collagen and thereby interferes with collagen-mediated
activation of platelets mediated by GPVI receptors (Liu et al. (Nat Med, 2011, 17, 206—210)). As
discussed above, plasma kallikrein inhibitors reduce plasma prekallikrein activation by inhibiting plasma
kallikrein-mediated activation of factor XII and thereby reducing the positive feedback amplification of
the kallikrein system by the contact activation system.
Therefore, inhibition of plasma kallikrein reduces the binding of plasma kallikrein to collagen, thus
reducing the interference of plasma kallikrein in the cessation of bleeding. Therefore plasma kallikrein
tors would be useful in the treatment of treating cerebral haemorrhage and bleeding from post
operative surgery. For example, Liu et al. (Nat Med, 2011, 17, 206—210) demonstrated that systemic
administration of a small molecule PK inhibitor, ASP-440, reduced hematoma expansion in rats. Cerebral
hematoma may occur following intracerebral haemorrhage and is caused by ng from blood vessels
into the surrounding brain tissue as a result of vascular injury. Bleeding in the cerebral haemorrhage
model reported by Liu et al. was induced by surgical ention involving an on in the brain
parenchyma that damaged blood vessels. These data demonstrate that plasma kallikrein inhibition
d bleeding and hematoma volume from post operative surgery. Bjérkqvist et al. (Thrombosis and
Haemostasis, 2013, 110, 399- 407) demonstrated that aprotinin (a protein that inhibits serine proteases
including plasma kallikrein) may be used to decrease erative bleeding.
Other complications of diabetes such as cerebral haemorrhage, pathy, cardiomyopathy and
neuropathy, all of which have associations with plasma kallikrein may also be considered as targets for a
plasma kallikrein inhibitor.

Kolte et al. (”Biochemical characterization of a novel high-affinity and ic kallikrein inhibitor”, British
Journal of Pharmacology (2011), 162(7), 1639-1649). Also, Steinmetzer et al. (”Serine protease
inhibitors” W02012/004678) describes cyclized peptide analogs which are inhibitors of human plasmin
and plasma kallikrein.
To date, no small molecule synthetic plasma rein inhibitor has been approved for medical use. The
molecules described in the known art suffer from limitations such as poor selectivity over related
enzymes such as KLK1, thrombin and other serine proteases, and poor oral availability. The large protein
plasma kallikrein tors present risks of lactic reactions, as has been reported for Ecallantide.
Thus there remains a need for nds that selectively inhibit plasma kallikrein, that do not induce
anaphylaxis and that are orally available. Furthermore, the vast majority of molecules in the known art
feature a highly polar and ionisable guanidine or amidine functionality. It is well known that such
functionalities may be limiting to gut permeability and therefore to oral bility. For example, it has
been reported by Tamie J. Chi/cote and o Sinha (”ASP-634: An Oral Drug Candidate for Diabetic
MacularEdema”, ARVO 2012 May 6th — May 9th, 2012, Fort Lauderdale, a, Presentation 2240) that
ASP-440, a benzamidine, suffers from poor oral availability. It is further reported that absorption may be
improved by creating a prodrug such as ASP-634. However, it is well known that prodrugs can suffer
from several drawbacks, for example, poor chemical ity and potential toxicity from the inert carrier
or from unexpected metabolites. In another report, indole amides are claimed as compounds that might
overcome problems associated with drugs possessing poor or inadequate ADME-tox and
physicochemical properties although no inhibition against plasma kallikrein is presented or claimed
(Griffioen et al, ”Indole amide derivatives and related compounds for use in the treatment of
neurodegenerative diseases”, WOZOlO, 142801).
BioCryst ceuticals Inc. have reported the discovery of the orally available plasma kallikrein
inhibitor BCX4161(”BCX4161, An Oral Kallikrein Inhibitor: Safety and cokinetic Results Of a
Phase 1 Study In Healthy eers”, l of Allergy and al Immunology, Volume 133, Issue 2,
Supplement, February 2014, page A339 and ”A Simple, Sensitive and Selective Fluorogenic Assay to
r Plasma Kallikrein Inhibitory Activity of BCX4161 in Activated Plasma”, Journal of Allergy and
Clinical Immunology, Volume 133, Issue 2, Supplement ry 2014, page AB40). However, human
doses are relatively large, currently being tested in proof of t studies at doses of 400 mg three
times daily.
There are only few reports of plasma kallikrein inhibitors that do not feature guanidine or amidine
functionalities. One example is Brandl et al. (”N-((6-amino-pyridinyl)methyl)-heteroaryl-carboxamides
as inhibitors of plasma kallikrein” W02012/017020), which bes compounds that feature an amino-
pyridine functionality. Oral efficacy in a rat model is demonstrated at relatively high doses of 30 mg/kg
and 100 mg/kg but the pharmacokinetic profile is not reported. Thus it is not yet known whether such
compounds will provide sufficient oral availability or efficacy for progression to the clinic. Other
examples are Brandl et al. (”Aminopyridine tives as plasma kallikrein inhibitors” W02013/111107)
and Flohr et al. (”5-membered heteroarylcarboxamide derivatives as plasma kallikrein inhibitors”
W02013/111108). However, neither of these nts report any in vivo data and therefore it is not
yet known r such compounds will provide sufficient oral availability or efficacy for progression to
the clinic. Another example is Allan et al. ”Benzylamine tives” W02014/108679.
Therefore there remains a need to develop new plasma kallikrein inhibitors that will have utility to treat
a wide range of disorders, in particular to reduce retinal vascular permeability ated with diabetic
retinopathy and diabetic macular edema. Preferred compounds will possess a good cokinetic
profile and in particular will be suitable as drugs for oral delivery.

General s
The compounds of the invention should be assessed for their biopharmaceutical properties, such as
solubility and solution ity (across pH), permeability, etc., in order to select the most appropriate
dosage form and route of administration for treatment of the proposed indication. They may be
administered alone or in combination with one or more other compounds of the invention or in
combination with one or more other drugs (or as any combination thereof). Generally, they will be
administered as a formulation in association with one or more pharmaceutically acceptable excipients.
The term ’excipient’ is used herein to describe any ingredient other than the compound(s) of the
ion which may impart either a functional (i.e., drug release rate controlling) and/or a non-
functional (i.e., processing aid or diluent) teristic to the formulations. The choice of excipient will
to a large extent depend on factors such as the particular mode of administration, the effect of the
excipient on lity and stability, and the nature of the dosage form.
Compounds of the invention intended for pharmaceutical use may be administered as a solid or liquid,
such as a tablet, capsule or solution. Pharmaceutical compositions suitable for the delivery of
compounds of the present invention and methods for their preparation will be readily apparent to those
skilled in the art. Such compositions and methods for their ation may be found, for example, in
Remington’s Pharmaceutical es, 19th Edition (Mack Publishing Company, 1995).
Accordingly, the present invention provides a pharmaceutical composition comprising a compound of
the invention and a ceutically acceptable carrier, diluent or ent.
For the treatment of conditions such as retinal vascular permeability associated with diabetic
retinopathy and diabetic macular edema, the compounds of the invention may be administered in a
form suitable for injection into the ocular region of a patient, in particular, in a form le for intra-
vitreal injection. It is envisaged that formulations suitable for such use will take the form of sterile
solutions of a compound of the invention in a suitable aqueous vehicle. The compositions may be
administered to the patient under the supervision of the attending physician.
The compounds of the invention may also be administered directly into the blood stream, into
subcutaneous tissue, into muscle, or into an internal organ. Suitable means for parenteral
administration include intravenous, intraarterial, intraperitoneal, intrathecal, intraventricular,
intraurethral, intrasternal, intracranial, uscular, intrasynovial and subcutaneous. Suitable devices
for parenteral stration include needle (including microneedle) injectors, needle-free injectors and

Parenteral formulations are typically aqueous or oily solutions. Where the solution is aqueous,
excipients such as sugars (including but not restricted to glucose, manitol, sorbitol, etc.), salts,
carbohydrates and buffering agents rably to a pH of from 3 to 9), but, for some applications, they
may be more suitably formulated as a sterile non-aqueous solution or as a dried form to be used in
conjunction with a suitable e such as sterile, pyrogen-free water.
Parenteral formulations may include implants derived from degradable polymers such as polyesters (i.e.,
polylactic acid, polylactide, polylactide-co-glycolide, polycapro-lactone, polyhydroxybutyrate),
polyorthoesters and polyanhydrides. These formulations may be administered via al incision into
the subcutaneous tissue, muscular tissue or directly into specific organs.
The preparation of parenteral formulations under sterile conditions, for example, by lyophilisation, may
y be lished using rd pharmaceutical techniques well known to those skilled in the
The lity of compounds of the ion used in the preparation of parenteral solutions may be
increased by the use of appropriate formulation techniques, such as the incorporation of co-solvents
and/or solubility-enhancing agents such as surfactants, micelle structures and cyclodextrins.
In one embodiment, the compounds of the invention may be administered orally. Oral administration
may involve swallowing, so that the compound enters the gastrointestinal tract, and/or buccal, lingual,
or gual stration by which the compound enters the blood stream directly from the mouth.
Formulations suitable for oral administration include solid plugs, solid microparticulates, semi-solid and
liquid (including multiple phases or dispersed systems) such as tablets; soft or hard capsules containing
multi- or nano-particulates, liquids, emulsions or powders; es ding liquid-filled); chews; gels;
fast dispersing dosage forms; films; ovules; sprays; and buccal/mucoadhesive patches.
Formulations suitable for oral administration may also be designed to deliver the compounds of the
invention in an immediate release manner or in a rate-sustaining , wherein the release profile
WO 07983
can be delayed, , controlled, sustained, or delayed and sustained or modified in such a manner
which ses the therapeutic efficacy of the said compounds. Means to deliver compounds in a rate-
sustaining manner are known in the art and include slow release polymers that can be formulated with
the said compounds to control their release.
Examples of rate-sustaining rs e degradable and non-degradable polymers that can be
used to release the said compounds by diffusion or a combination of diffusion and polymer erosion.
Examples of rate-sustaining rs include hydroxypropyl methylcellulose, hydroxypropyl cellulose,
methyl cellulose, ethyl cellulose, sodium carboxymethyl cellulose, nyl alcohol, polyvinyl
pyrrolidone, xanthum gum, polymethacrylates, polyethylene oxide and polyethylene glycol.
Liquid (including multiple phases and dispersed s) formulations include ons, solutions,
syrups and elixirs. Such formulations may be presented as fillers in soft or hard capsules (made, for
example, from gelatin or ypropylmethylcellulose) and typically comprise a carrier, for example,
water, ethanol, polyethylene glycol, propylene glycol, methylcellulose, or a suitable oil, and one or more
emulsifying agents and/or suspending agents. Liquid formulations may also be prepared by the
reconstitution of a solid, for example, from a sachet.
The nds of the invention may also be used in fast-dissolving, fast-disintegrating dosage forms
such as those described in Liang and Chen, Expert Opinion in Therapeutic s, 2001, 11 (6), 981-986.
The formulation of tablets is discussed in Pharmaceutical Dosage Forms: Tablets, Vol. 1, by H. Lieberman
and L. Lachman (Marcel Dekker, New York, 1980).
For administration to human ts, the total daily dose of the compounds of the invention is typically
in the range 0.1 mg and 10,000 mg, or between 1 mg and 5000 mg, or between 10 mg and 1000 mg
depending, of course, on the mode of administration. |f administered by intra-vitreal injection a lower
dose of between 0.0001 mg (0.1 ug) and 0.2 mg (200 pg) per eye is envisaged, or between 0.0005 mg
(0.5 ug) and 0.05 mg (50 pg) per eye.
The total dose may be administered in single or divided doses and may, at the physician's discretion, fall
outside of the typical range given herein. These dosages are based on an average human subject having
a weight of about 60kg to 70kg. The physician will readily be able to determine doses for subjects
whose weight falls outside this range, such as infants and the elderly.
Synthetic Methods
The compounds of the present invention can be prepared according to the procedures of the following
schemes and examples, using appropriate materials, and are r exemplified by the specific
examples ed herein below. Moreover, by utilising the ures described herein, one of
ry skill in the art can readily prepare additional compounds that fall within the scope of the
present invention claimed herein. The compounds illustrated in the examples are not, however, to be
construed as forming the only genus that is considered as the invention. The examples further illustrate
details for the preparation of the compounds of the t invention. Those skilled in the art will
readily tand that known variations of the conditions and processes of the following preparative
procedures can be used to e these compounds.
The compounds of the invention may be isolated in the form of their pharmaceutically acceptable salts,
such as those described previously herein above.
It may be ary to protect reactive functional groups (e.g. hydroxy, amino, thio or carboxy) in
intermediates used in the preparation of nds of the invention to avoid their unwanted
participation in a reaction leading to the formation of the compounds. Conventional protecting groups,
for example those described by T. W. Greene and P. G. M. Wuts in ”Protective groups in organic
chemistry” John Wiley and Sons, 4th Edition, 2006, may be used. For example, a common amino
ting group suitable for use herein is tert-butoxy carbonyl (Boc), which is readily removed by
treatment with an acid such as oroacetic acid or hydrogen de in an organic t such as
dichloromethane. Alternatively the amino protecting group may be a benzyloxycarbonyl (2) group
which can be removed by hydrogenation with a palladium catalyst under a hydrogen atmosphere or 9-
fluorenylmethyloxycarbonyl (Fmoc) group which can be removed by solutions of secondary organic
amines such as lamine or piperidine in an organic solvent. Carboxyl groups are typically protected
as esters such as methyl, ethyl, benzyl or tert-butyl which can all be removed by ysis in the
presence of bases such as lithium or sodium hydroxide. Benzyl protecting groups can also be removed
by enation with a palladium catalyst under a hydrogen atmosphere whilst tert-butyl groups can
also be removed by trifluoroacetic acid. Alternatively a trichloroethyl ester protecting group is removed
with zinc in acetic acid. A common hydroxy protecting group suitable for use herein is a methyl ether,
deprotection conditions comprise refluxing in 48% aqueous HBr for 1-24 hours, or by stirring with
borane tribromide in dichloromethane for 1-24 hours. Alternatively where a hydroxy group is protected
as a benzyl ether, deprotection conditions comprise hydrogenation with a palladium st under a
hydrogen atmosphere.

In Scheme 1, the amine 2 is coupled to an acid 1 to give the compound 3. This coupling is typically
carried out using standard coupling conditions such as hydroxybenzotriazole and a carbodiimide, such as

Determination of enzyme ivity
Human serine protease enzymes plasmin, thrombin and trypsin were d for enzymatic activity
using an appropriate fluorogenic substrate. se activity was measured by monitoring the
accumulation of liberated fluorescence from the substrate over 5 minutes. The linear rate of
fluorescence increase per minute was expressed as percentage (%) activity. The Km for the cleavage of
each substrate was determined by standard transformation of the Michaelis-Menten equation. The
compound tor assays were performed at substrate Km concentration and activities were
ated as the concentration of inhibitor giving 50% inhibition (IC50) of the uninhibited enzyme
activity (100%).
Data acquired from these assays are shown in Table 12 below:

In vitro ADME data
In vitro permeability was determined using the Caco-2 model for oral absorption. The methodology was
adapted from standard published methods (Wang Z, Hop C.E., Leung K.H. and Pang J. (2000)J Mass
Spectrom 35(1); 71-76). The Caco-2 monolayers were established in a BiocoatTlvl HTS fibrillar collagen 24
well multiwell insert system (1.0 pm, PET membrane, g 354803) in which 0 cells were
seeded into each insert and maintained over 3 days before being utilised in the permeability assay. For
the assay, 50 uM test compound is added to the apical side of the inserts and incubated for 1 hour at 37
°C on a shaking platform (120 rpm). Apical to basolateral transport was determined by ing the
test e in both tments by LCMS following the 1 hour incubation. The integrity of the Caco-2
monolayers was confirmed by two methods, (i) comparison of pre- and xperiment transepithelial
electrical resistance (TEER) and, (ii) assessment of Lucifer Yellow flux.
The intrinsic clearance was determined using standard published methods (Obach RS (1999) Drug Metab
Dispos 27(11); 1350-135). Rat or human liver microsomes (0.5 mg/mL; Corning) were incubated with 5
uM test compound at 37 °C on a shaking platform (150 rpm). Samples were taken at 0, 6, 12, 18, 24 and
60 min and test compound concentrations were determined by LCMS against a calibration curve. The
intrinsic nce (Clint) was calculated using methodology described by Obach (Obach RS et al. (1997) J
Pharmacol Exp Ther 283: 46—58.) or Lau (Lau YY et al . Drug Metab Dispos 30: 1446—1454).

Plasma Protein Binding (PPBl and Predicted Clearance
The fraction unbound in plasma was determined using ThermoScientificTM PierceTM Rapid Equilibrium
Dialysis Technology e-Use plate with inserts, 8K MWCO). 5 uM test compound was spiked into
human or rat plasma (300 uL) and dialysed against 146.5 mM phosphate buffer (500 uL) for 5 hrs at
37°C, shaking at 1200 rpm. Reference samples from the non-dialysed plasma were taken before the
incubation to enable an assessment of recovery. Test nd concentrations were determined in
plasma and buffer compartments by LCMS against a calibration curve. The fraction unbound in plasma
was determined using standard methodology s NJ et al (2008)J Pharm Sci 97(10); 4586-95).
Results are ted as percent plasma n bound (%PPB).
The ted plasma clearance (Clp) is calculated using the well-stirred model (Rowland M, Benet L2,
and Graham 66. Clearance concepts in pharmacokinetics.J Pharmacokinet rm. (1973) 1:123—
136.), one of several models that can be used to extrapolate the in vitro data. The model assumes
instantaneous and complete mixing of drug within the liver and is a function of intrinsic clearance,
