Description

The present invention relates to a family of differently substituted isatins that exhibit protein kinase inhibitory activity with leucine-rich repeats (LRRK2), so they are useful for the treatment of diseases mediated by this enzyme, such as inflammatory diseases, autoimmune and neurodegenerative diseases, especially Parkinson's disease.

STATE OF THE TECHNIQUE

Leucine-rich repeat kinase protein (leucine-rich repeat kinase 2, LRRK2) is a 280 KDa protein first described in 2004. LRRK2 contains two active domains (GTPase and kinase) as well as other protein-protein interaction motifs. , whose function is unknown. The majority of pathogenic mutations in LRRK2 occur in the GTPase and kinase domains being directly related to Parkinson's disease. The catalytic site formed by ROC and GTPase acts as a molecular switch for a wide variety of cell signal transmission pathways. Flanking the two catalytic domains we find several protein-protein interaction domains, the Leu-rich Nterminal domain (LRR) and the C-terminal domain (WD40 domain). Some of the functions of LRRK2 are vesicular traffic, microtubule dynamics, neurite growth and cellular functions such as lysosomal protein degradation. The dynamics of microtubules is crucial for the transport of membrane to different sites of the cell in processes of autophagy and synaptic vesicular traffic.

The discovery of LRRK2 began with the identification of several families of patients suffering from Parkinson's disease with a clear genetic component, but which, however, did not fit any of the known mutations up to that time. Mutations in LRRK2 are the most common genetic cause for Parkinson's disease, with 4% of family cases and 1% of sporadic cases.

LRRK2 is abundantly expressed in microglia in addition to neurons, having been shown to be a positive modulator of inflammation in murine microglia and that mutations in LRRK2 can alter the brain microenvironment favoring neuroinflammation. Therefore, it can be related to various neurodegenerative diseases that occur with neuroinflammation, such as Alzheimer's disease, Parkinson's disease, multiple sclerosis and amyotrophic lateral sclerosis, and their inhibitors play a neuroprotective role by decreasing the inflammatory response. In addition, LRRK2 increases the activity of the GSK-3 enzyme and therefore, hyperphosphorylation of the TAU protein and other pathological proteins such as TDP-3 is promoted. This known relationship allows us to establish which compounds that inhibit the activity of LRRK2 will indirectly decrease the phosphorylation of tau and TDP-43, so that LRRK2 inhibitors may be useful for the treatment of tautopathies such as Alzheimer's disease, supranuclear paralysis progressive, frontotemporal dementia, Pick's disease, etc., and diseases associated with TDP-43 such as amyotrophic lateral sclerosis, frontotemporal dementia, Alzheimer's disease, among others.

Neurodegenerative diseases are diseases that do not currently have an effective drug treatment. The number of people who suffer from them is increasing given the increase in life expectancy, which implies a high personal, family and social cost. For all this, it is especially important to search for new molecules that may be candidates for drugs.

Parkinson's disease is characterized by the presence of tremor, stiffness, bradykinesia and postural instability. The sporadic form of Parkinson's disease is the majority, compared to 5% of cases of family or inherited type. The incidence of this disease increases with age, affecting one in 1000 adults over 65 years. Both genetic and environmental factors contribute to the pathogenesis of the disease, although the molecular mechanisms involved in Parkinson's disease are unknown. In this disease there is a loss of dopaminergic neurons that are located in the black substance and produce the innervation of the striatum, observing the presence of protein aggregates in inclusions called Lewy bodies in the spinal bulb neurons.

The formation of Lewy bodies is due to the failure of the cell degradation system and they are formed by aggregates of proteins, mainly D-synuclein. This protein is expressed in the brain and although its function is not yet clear, it may appear to be involved in neurotransmission functions, and processes.

5 plasticity.

Recently, this disease has been linked to mutations in various genes. The vast majority of Parkinson's patients with G2019S mutation in LRRK2 have clinical and neuropathological characteristics practically

10 indistinguishable from those observed in the sporadic type. In addition, mutations in LRRK2 have been related to autophagic balance, which could lead to cell death in the presence of another component, still undetermined.

Additionally, it has also been shown that LRRK2 is highly

15 expressed in circulating immune cells suggesting a potential function of LRRK2 in immune and inflammatory processes, being related to inflammatory bowel diseases such as Crohn's disease, irritable bowel syndrome or ulcerative colitis.

20 WO2011057204 describes seven different families of compounds that inhibit the LRRK2 enzyme for the treatment of neurodegenerative diseases, especially Parkinson's, and autoimmune diseases. One of these seven families is represented by the following formula:

So far, different LRRK2 inhibitors have been described, but they have the difficulty of not crossing the blood brain barrier or being poorly selective against other protein kinases; so they cannot be drug candidate molecules for the treatment of nervous system diseases

central [Small molecule kinase inhibitors for LRRK2 and their application to Parkinson's disease models. Kramer T, Lo Monte F, Goring S, Okala Amombo G. M, Schmidt B. ACS Chem. Neurosci. 2012, 3, 151-160].

5 Thus, given that there is a need for advantageous therapeutic agents, the design and synthesis of molecules that are selective of the LRRK2 protein for the treatment of inflammatory and autoimmune diseases, and also with the ability to penetrate, is of vital importance. in the central nervous system for the treatment of neurodegenerative diseases.

SHORT DESCRIPTION

The authors of the present invention have found a family of substituted isatins that inhibit the protein kinase LRRK2 and which also have the advantage

An additional technique of being able to cross the blood brain barrier that distinguishes them from other inhibitors of this same kinase described in the prior art. In addition, they present another technical characteristic such as being ATP-competitive which allows them to bind to the enzyme in the kinase catalytic domain.

The isotope-labeled compounds of the present invention, for example those in which radioactive isotopes such as 3H or 14C are incorporated, are useful in drug and / or tissue distribution assays. Particularly preferred are tritium isotopes, i.e. 3H, and carbon-14, i.e. 14C, for their ease of preparation and detectability. Isotopes 11C and 18F are particularly useful in PET (positron emission tomography), and isotopes 125I are particularly useful in SPECT (single photon emission computed tomography), all useful in brain imaging. In addition, replacement with heavier isotopes such as deuterium, i.e., 2H, may provide some therapeutic advantages that result from increased metabolic stability, for example, longer half-life in vivo or lower dosage requirements, and therefore in some Cases may be preferred. The isotopically labeled compounds of formulas (I) and (II) can generally be prepared by performing the procedures described in the examples below, substituting an isotopically unlabeled reagent for an easily available isotopically labeled reagent.

Example 3: Permeability in the central nervous system (CNS) using parallel artificial membranes (PAMPA) of the compounds of the invention.

The prediction of the permeability of the various compounds on the central nervous system (CNS), passage of the blood brain barrier, was determined using the parallel artificial membrane methodology (PAMPA) [Di, L .; Kerns,

E. H .; Fan, K .; McConnell, O. J .; Carter, G. T. “High throughput artificial membrane permeability assay for blood – brain barrier” Eur. J. Med. Chem., 2003, 38 (3), 223-232]. In order to filter the samples PDVF membrane filters (30 mm in diameter, pore size 0.45 µm) were used. Ten reference compounds were selected, whose blood brain barrier passage is known and public, in order to validate the experiment. Different amounts of the same 3-5 mg of caffeine, enoxacin, hydrocortisone, desipramine, ofloxacin, piroxicam and testosterone, 12 mg of promazine, and 25 mg of verapamil and atenolol were taken, which were dissolved in ethanol (1000 mL). 100 mL of these solutions 15 were taken and 1400 mL of ethanol and 3500 mL of PBS (pH = 7.4) were added, in order to reach a final ethanol concentration of 30% in the solution. The solutions were filtered. Subsequently, 180 µL of a solution of PBS / ethanol (70/30) was added to each well of the acceptor plate. The donor plate was impregnated with 4 mL of a solution of porcine brain lipid dissolved in dodecane (20 mg mL-1). After 5 min, 180 µL of solution of each compound was added on this plate. Of the compounds to evaluate their penetration into the central nervous system, they were taken between 1-2 mg and dissolved in 1500 mL of ethanol and 3500 mL of PBS (pH = 7.4), filtered and added to the donor plate 96 wells. Then the donor plate was placed on the acceptor forming a kind of "sandwich" and left incubating for 2h and 30 min at 25 ° C. The compounds, by passive transport, will pass from the donor plate through the porcine brain lipid to the acceptor plate. After 2:30 and 30 min, the donor plate is carefully removed. The concentration and absorbance of both commercial compounds and synthesized derivatives that were evaluated in the acceptor and donor plates were determined using a UV absorbance reader. Each sample was analyzed at different wavelengths (3 to 5), in 3 wells and in at least 2 independent experiments. The results are the average of the measures ± standard deviation of the different experiments performed. In relation to the 10

Commercial reference compounds used in each experiment in order to validate the method, a good correlation was found between the experimental (Pe) permeability values and those described, Pe (exp) = 1.1512 (bibl) - 0.8973 (R2 = 0.977). From this equation and following the pattern described in literature 5 for the prediction of blood brain barrier permeability, the compounds can be classified as permeable to the central nervous system (CNS) when they have a permeability> 3.71 x 10-6 cm s -one. All compounds with a% inhibition against LRRK2> 60% were evaluated. The results are shown in table 2, where it can be seen as all

10 compounds evaluated are capable of crossing the blood brain barrier.
