This invention relates to compounds, compositions, and methods for treating diseases and conditions in mammals.
A variety of hormones, neurotransmitters and biologically active substances control, regulate or adjust the functions of living bodies via specific receptors located in cell membranes. Many of these receptors mediate the transmission of intracellular signals by activating guanine nucleotide-binding proteins (G proteins) to which the receptor is coupled. Such receptors are generically referred to as G-protein coupled receptors (GPCRs) and include, among others, α-adrenergic receptors, β-adrenergic receptors, opioid receptors, cannabinoid receptors and prostaglandin receptors. The biological effects of activating these receptors is not direct but is mediated by a host of intracellular proteins. The importance of these secondary proteins has only recently been recognized and investigated as intervention points in disease states. One of the most important classes of these downstream effectors is the “kinase” class.
Kinases thus play important roles in the regulation of various physiological functions. For example, alterations in kinase activity have been implicated in a number of disease states, including, but not limited to: cardiac indications such as angina pectoris, essential hypertension, myocardial infarction, supraventricular and ventricular arrhythmias, congestive heart failure, atherosclerosis, renal failure, diabetes, respiratory indications such as asthma, chronic bronchitis, bronchospasm, emphysema, airway obstruction, upper respiratory indications such as rhinitis, seasonal allergies, inflammatory disease, inflammation in response to injury, and rheumatoid arthritis. The importance of p38 MAPK inhibitors in particular as new drugs for rheumatoid arthritis is reflected by the large number of compounds that has been developed over the last years (J. Westra and P. C. Limburg Mini-Reviews in Medicinal Chemistry Volume 6, Number 8, August 2006) Other conditions that involve changes in kinase activity include chronic inflammatory bowel disease, glaucoma, hypergastrinemia, gastrointestinal indications such as acid/peptic disorder, erosive esophagitis, gastrointestinal hypersecretion, mastocytosis, gastrointestinal reflux, peptic ulcer, Zollinger-Ellison syndrome, pain, obesity, bulimia nervosa, depression, obsessive-compulsive disorder, organ malformations (e.g., cardiac malformations), neurodegenerative diseases such as Parkinson's Disease and Alzheimer's Disease, multiple sclerosis, Epstein-Barr infection and cancer (Nature Reviews Drug Discovery 1, 493-502 2002). In other disease states, the roles of the various kinases are only now becoming clear. The retina is a complex tissue composed of multiple interconnected cell layers, highly specialized for transforming light and color into electrical signals that are perceived by the brain. Damage or death of the primary light-sensing cells, the photoreceptors, results in devastating effects on vision. Despite the identification of numerous mutations that cause inherited retinal degenerations, the cellular and molecular mechanisms leading from the primary mutations to photoreceptor apoptosis are not well understood, but may involve the Wnt pathway (A S Hackam The Wnt Signaling Pathway in Retinal Degeneration IUBMB Life Volume 57, Number 6/June 2005).
The success of the tyrosine-kinase inhibitor STI571 (Gleevec) in the treatment of chronic myelogenous leukaemia (Nature Reviews Drug Discovery 2, 296-313 2003) has spurred considerable efforts to develop other kinase inhibitors for the treatment of a wide range of other cancers (Nature Reviews Cancer 3, 650-665 2003). In view of the role that kinases have in many disease states, there is an urgent and continuing need for small molecule ligands which inhibit or modulate the activity of kinases.
Another class of proteins that have proven important in the development of new medicaments is the monoamine transporter class. Monoamine transporters (MAT) are proteins found in both neuronal and non-neuronal cell membranes that function to transport monoamine neurotransmitters into or out of cells. There are several distinct monoamine transporters, or MATs: the dopamine transporter, DAT, the norepinephrine transporter, NET and the serotonin transporter, SERT. DAT, NET and SERT are related to each other in amino acid sequence and protein structure, with each containing 12 trans-membrane helices. The discovery of NET and SERT has led to new drugs, mostly acting via central nervous system (CNS) pharmacology. Modern antidepressants typically work by enhancing serotonergic, noradrenergic or dopaminergic neurotransmission by binding to the corresponding transporter, and inhibiting neurotransmitter reuptake, thereby raising active levels of neurotransmitter in the synapse. Examples include fluoxetine, a selective serotonin reuptake inhibitor; reboxetine, a norepinephrine reuptake inhibitor and bupropion, which inhibits both the norepinephrine and dopamine transporter.

This invention relates to compounds, compositions, and methods for treating diseases and conditions wherein an inhibitor of a kinase, such as rho kinase (ROCK), and an inhibitor of one or more of the monoamine transporters, such as NET or SERT, will act in concert to improve the condition. One such area is the treatment of glaucoma by producing, inter alia, a reduction in intraocular pressure (IOP), or anti-inflammatory effects or neuroprotection.

These may be separate molecules, but ideally they are part of the same molecule. The same portions of that molecule may act on both systems, or separate but connected parts of the molecule may act more or less independently to bring about inhibition of both systems.

The anterior section of porcine eyes was harvested within 4 hours post-mortem. The iris and ciliary body were removed and trabecular meshwork cells were harvested by blunt dissection. Finely minced trabecular meshwork tissue was plated into collagen-coated 6-well plates in Medium-199 containing 20% fetal bovine serum (FBS). After two passages at confluence, cells were transferred to low-glucose DMEM containing 10% FBS. Cells were used between passage 3 and passage 8.
Cells were plated into fibronectin-coated, glass multiwell plates the day before compounds were tested under standard culture conditions. Compounds were added to cells in the presence of 1% FBS-containing DMEM and 1% DMSO. When compounds were incubated with the cells for the duration determined to be optimal, the media and compound is removed and cells fixed for 20 minutes in 3% methanol-free paraformaldehyde. Cells were rinsed twice with phosphate buffered saline (PBS) and cells are permeabilized with 0.5% Triton X-100 for two minutes. Following an additional two washes with PBS, F-actin was stained with Alexa-fluor 488-labelled phalloidin and nuclei are stained with DAPI.
Data was reduced to the mean straight actin-fiber length and normalized to DMSO-treated control cells (100%) and 50 μM Y-27632 (0%). Y-27632 is a rho-kinase inhibitor known to cause disruption of the actin cytoskeleton in these cells.

Total cell membranes were prepared from MDCK cells expressing the recombinant human norepinehrine transporter (hNET) grown to confluence in 150 mm tissue culture dishes. Cells were scraped into standard medium and pelleted at 1600 g. The medium was discarded and the pellet resuspended in 5 ml per plate of ice-cold binding buffer (100 mM NaCl, 50 mM Tris, pH 7.4 at room temperature) by trituration, and the cells were repelleted at 20,000 g. Supernatant was discarded and cells were resuspended in binding buffer (50 mM Tris-HCl, pH 7.4, 100 mM NaCl, 1 μM leupeptin, 10 μM PMSF) and homogenized with a polytron (Brinkman) at 25,000 revs/min for 5 s. Centrifugation, resuspension and homogenization were repeated and a sample of suspension was used for Bradford protein determination (BioRad). Samples of membrane suspensions were frozen at −80° C. prior to use. Typical yields were about 100 μg membrane protein per 106 cells. Assays performed in duplicate were initiated with 0.2 nM [125 l]RTI-55. Non-specific binding was determined by the inclusion of 10 μM desipramine. Incubation was carried out for 3 hours at 4° C. Assays were terminated by rapid filtration over GF/B glass-fiber filters soaked in 0.5% polyethylineimine using an automated cell harvester (Brandel) followed by three rapid 5 ml washes in ice-cold binding buffer. Bound radioactivity was measured by gamma emission spectrometry.

Pharmacological activity for glaucoma can be demonstrated using assays designed to test the ability of the subject compounds to decrease intraocular pressure. Examples of such assays are described in the following reference, incorporated herein by reference: C. Liljebris, G. Selen, B. Resul, J. Sternschantz, and U. Hacksell, “Derivatives of 17-phenyl-18,19,20-trinorprostaglandin F2alpha Isopropyl Ester: Potential Anti-glaucoma Agents”, Journal of Medicinal Chemistry 1995, 38 (2): 289-304.
All temperatures were in degrees Centigrade. Reagents and starting materials were purchased from commercial sources or prepared following published literature procedures.
Unless otherwise noted, HPLC purification, when appropriate, was performed by redissolving the compound in a small volume of DMSO and filtering through a 0.45 micron (nylon disc) syringe filter. The solution was then purified using, for example, a 50 mm Varian Dynamax HPLC 21.4 mm Microsorb Guard-8 C8 column. A typical initial eluting mixture of 40-80% MeOH:H2O was selected as appropriate for the target compound. This initial gradient was maintained for 0.5 min then increased to 100% MeOH:0% H2O over 5 min. 100% MeOH was maintained for 2 more min before re-equilibration back to the initial starting gradient. A typical total run time was 8 min. The resulting fractions were analyzed, combined as appropriate, and then evaporated to provide purified material.
Proton magnetic resonance (1H NMR) spectra were recorded on either a Varian INOVA 600 MHz (1H) NMR spectrometer, Varian INOVA 500 MHz (1H) NMR spectrometer, Varian Mercury 300 MHz (1H) NMR spectrometer, or a Varian Mercury 200 MHz (1H) NMR spectrometer. All spectra were determined in the solvents indicated. Although chemical shifts are reported in ppm downfield of tetramethylsilane, they are referenced to the residual proton peak of the respective solvent peak for 1H NMR. Interproton coupling constants are reported in Hertz (Hz).
Analytical LCMS spectra were obtained using a Waters ZQ MS ESI instrument with an Alliance 2695 HPLC and a 2487 dual wavelength UV detector. Spectra were analyzed at 254 and 230 nm. Samples were passed through a Waters Symmetry C18 4.6×75 mm 3.5μ column with or without a guard column (3.9×20 mm 5μ). Gradients were run with mobile phase A: 0.1% formic acid in H2O and mobile phase B: ACN with a flow rate of 0.8 mL/min. Two gradients will illustrate:
The settings for the MS probe were a cone voltage at 38 mV and a desolvation temperature at 250° C. Any variations in these methods are noted below.
