Inhibition of the serine protease HtrAl, which belongs to an evolutionarily conserved family of HtrA proteins, has the potential to protect and treat tissue damage caused by the degeneration of retinal or photoreceptor cells in the human eye. The pathophysiological relevance of HtrAl in the progression of the age-related macular degeneration has been firmly established by human genetic studies where a SNP in the HtrAl promoter region results in increased HtrAl transcript and protein levels. Age-related macular degeneration is the leading cause of severe irreversible central vision loss and blindness in individuals over 65 years of age in developed countries. There are two forms of AMD: dry AMD and wet AMD. Wet AMD (also known as exudative AMD), is associated with pathologic posterior choroidal neovascularization subsequent to the disruption of the delimiting Bruch's membrane. Tissue edema due to the leakage from the abnormal blood vessels damages the macula and impairs vision, eventually leading to blindness. In dry AMD, drusen have been reported in the macula of the eye, the cells in the macula die for the progressive accumulation of the drusen, resulting in progressive vision loss. Dry AMD is clinically described to occur in three stages: 1) early, 2) intermediate, and 3) advanced dry AMD. Dry AMD can also progress into wet AMD during any stage of the disease. Treatment strategies for wet AMD exists and the current standard of care is Lucentis
(Genentech/Roche) and Eylea (Regeneron), an anti- VEGF antibody and an anti- VEGF trap injected intravitreally respectively. There are no current treatments for preventing loss of vision for the dry form and for preventing progression of dry AMD to local atrophy of the retinal tissue. As discussed above, HtrAl risk alleles have been associated, with high statistical significance, with the AMD onsets and the protein has been reported to be present in drusen. These studies and further evidences provide relevance that HtrAl is a fundamental factor involved in the pathophysiology and progression in AMD. This concept is further confirmed in different AMD disease models, where increased HtrAl protein levels in the retina tissue have been shown to be responsible for the degradation of extracellular matrix (ECM) proteins like fibronectin, fibulins and aggrecan. The physiological balance between production and disintegration of the ECM components allows for both creation and maintenance of proper retina tissue architecture. Such balance has been reported to be lost in the progression of the age-related macular degeneration. In particular, the fibulins (mainly-3, -5, -6) have been reported to be important components of the Bruch's membrane in maintaining the integrity of elastic lamina and organization of the retina tissue overall. Several variants in fibulin 5 and fibulin 3 were reported to be associated with AMD. Missense mutations of the fibulin 5 gene have been associated with reduced secretion of fibulin 5. Different studies have reported that Htral protease activity is directed to the cleavage of the fibulins as substrates. A direct inhibition of HtrAl protease activity is expected to provide a protection reducing degradation of extracellular matrix proteins, in particular fibulins and fibrionectin, therefore preserving the retina tissue structure. The relevance of HtrAl's role in maintenance of the physiological homeostasis of the ECM components is firmly provided by the identification of human loss-of-function mutations causing familial ischemic cerebral small- vessel disease. The molecular mechanism underlies in the deficient TGFbeta inhibition by HtrAl resulting in increased signaling levels, which in conjunction with deficient HtrAl -mediated degradation of various extracellular matrix components determine thickening of the intima responsible for the ischemic small-vessels. Given its fundamental role in regulating intracellular signaling pathways (e.g. TGFbeta) and the regulation of ECM proteins turnover, HtrAl has been involved in several pathologies, as ocular diseases, rheumatoid arthritis, osteoarthritis, Alzheimer's disease, and some types of cancer.

Assay procedures
Protein purification for use in enzymatic assays
Human HtrAl protein comprising the catalytic and the PDZ domain from amino acid Aspl61 up to Pro480 of was expressed in BL21(DE3) cells as an N-terminal fusion protein with a 6xHis-SUMO tag. The transformed cells were grown in LB medium at 37°C until the optical density at 600 nm was between 0.6 and 0.8. Then, the temperature was decreased to 18°C and the recombinant protein production induced by adding IPTG to a final concentration of 250 mM. Fermentation was performed over night at 18°C. The protein was purified to homogeneity following a four-step procedure. 40 g of cells were suspended in 50mM HEPES pH 7.8, 250 mM NaCl, 10 mM MgC12, 0.35% CHAPS, 10% glycerol containing 20 tabs per liter of EDTA-free cOmplete Protease Inhibitor (Roche) as well as 30 mg/1 DNAse and Rnase. The cells were broken by a single passage through a homogenizer at 750 bar and then centrifuged at 20'000xg for 30 minutes. The clear supernatant was applied on a triple 5 ml HisTrap column (GE Healthcare) equilibrated in 50 mM HEPES pH 7.8, 500 mM NaCl, 0.35% CHAPS, 10% glycerol. After washing with stepwise increasing concentrations of imidazole (20 mM, 40 mM, 50 mM) HtrAl fusion protein was eluted within a linear gradient from 10 to 100% of the same buffer containing 500 mM imidazole. HtrAl containing fractions were pooled, concentrated and then applied to a Superdex S200 prep grade (XK26/100 - GE Healthcare) column equilibrated in 50 mM ethanolamine pH 9.6, 500 mM NaCl, 0.35% CHAPS, 10% glycerol, 0.02% sodium azide. In order to cleave the SUMO fusion protein and to release active HtrAl, the pooled fractions from the size exclusion chromatography were blended with SUMO protease (Life Technologies) and incubated ca. 20 hours at RT. HtrAl was isolated out of the reaction solution by chromatography on a Superdex S200 prep grade (XK26/100 - GE Healthcare) column equilibrated 50 mM ethanolamine pH 9.6, 500 mM NaCl, 0.35% CHAPS, 10% glycerol, 0.02% sodium azide. Fractions containing active HtrAl were pooled and concentrated. Following the above strategy 150 mg of the HtrAl (catalytical domain/PDZ _
-63- construct) could be purified. As shown by RP-HPLC and SDS-PAGE, >98% pure protein was obtained.

Dnp=2,4-Dinitrophenyl
Final volume: 51 μΐ
Excitation 320 nm, emission 390 nm After a pre-incubation of the HtrAl protease for 30 min with compounds, substrate is added to the wells and initial RFU is measured. Upon incubation for 2 hours at RT, the enzymatic activity cleaved the substrate releasing fluorescent Mca-peptide conjugate and the final RFU value is measured. The presence of inhibitors leads to a decreased final RFU.
For the analysis ARFU is calculated as RFU en d-RFU s tart and then percent inhibition is calculated with the following formula:
PCT_Inhibition= 100-100* (ARFU compound -ARFU b i ank )/( ARFU negc tri-ARFU b i ank ) where neg.ctrl is protease with substrate and DMSO blank is as neg. Ctrl without protease compound is as neg. Ctrl with test compounds at desired concentration The IC 50 is determined using a 4-point Hill-fit equation where x=concentration of test compound
A= extrapolated value of the curve at effector concentration equals 0 B= extrapolated value of the curve at effector concentration equals infinite C=concentration at the inflection point of the sigmoidal curve (IC 50 ) D=Hill coefficient of slope at the inflection point of the fitted curve
As a counter screen the compounds are added to the protease-substrate reaction mix only after 2h incubation, when all the substrate is turned over, to identify auto-fluorescent or absorbing compounds giving false positive hits.
