BACKGROUND OF THE INVENTION

! . Field of the invention

The present invention relates to flavonoid derivatives and, more particularly, to cannabis flavonoid derivatives or the pharmaceutically acceptable salt thereof that may be used in a pbarraaceatical composition for pre venting and treating CMS related disease particularly Parkinson's, Akb.ei.rner, Huntington's disease, Mnltipie sclerosis, Amyotrophic lateral sclerosis (ALS), Hereditary diffuse leukoencephalopalhy with spheroids (HDLS) and epilepsy.

2. Description of the Background

Ftavonoids are common constituents of plants and cover a wide range of functions including acting as yellow pigments in petals and leaves to attract pollinating insects. They might also appear as bluish pigments (amhocyanirss) to receive certain -wavelengths of light, which permits the plant to be aware of the pSotoperiod. Many of these fiavonoids: also protect the■-plants by being, involved in the filtering of hatful ultravtplet light, Sorne fiavonoids play -crucial roles in. establishing symbiotic fioigi while at the sanre time they light infec« ^' dj«s caused by. ^' pathogenic fungi

FkvoRpids have relevant phaniiacoiogical activities such as; antioxidant, antidiabetic, an« ^' *infiammatofy, antiallergic, antibiotic, antidtarrheaJ, CHS and against cancer. Cannabis is -credited to have several beneficial pnamiacological- properties .

^' Uafortuaately much attention on Cannabis is focused on its recreational use as a psychoactive Aug. Studies have identified over twenty i!avonoids in the Caimabis plant, such as; cannflavin A, cauafiavifl B, cannflavin C, chrysoeril, cosmosiin, fiavocannabiside, vitexio, isoviiexiii, apigenin, kaernpferol, myricetin, querceiia, htteoiin, bomoorientk and orientin (Turner, C. E., Elsohly, M. A„ & Boeren, E, G„ "Constituents of Cannabis Sativa L. XVII., A review of the natural constituents", Journal of Natural .Products, 43(2), 169-234 (1980). The distri ution of these ikvoimids in the plant varies depending on the type of fkvonoidL The tots! content of f!avonoids in the Caraa is' leaves and flowers can reach 1- 25%. of its dry weight depending on in oament factors and the variety of the plant

Cannabis flavotioids have been shown io have several pharmacological properties. Apart from the specific pharmacologic properties identified, cannabis flavonoids are thought to play synergistic rotes with, other metabolites in the plant. For example, some flavonoids are volatile, .lipophilic, permeate membranes, and seem to retain

pharmacological properiies in cannabis smoke (Saner, M. A., Rifka, S. M., Hawks, . L„ Cutler, G. B„ & Loriaux, . L„ "Journal of Pharmacology and Experimental Therapeutics 224(2), 404-407 (1983). Flavonoids may modulate the pfaamiacok etfcs of ^' THC, via a mechanism shared by CBt ⁾ , the ioI iton of P4503A11 and P45i> 3A

-ei-xymes, These two related enzymes- metabolize environmental toxins from

proestro ens to their -acti\¾te forms, P450¾uppress&ig compoiritds as such serve as cheiiioprotecti ve agents,

ailatoxin Bl (Oflord, E. A., Mace, K,, Avaiui, O., & Pfeifer, A. M., "Mechanisms involved la The Chemoprotective Effects Of Rosemary Extract Studied In Human Liver And Bronchial Ceils", Cancer Letters, 114(1), 275-28.1 , (1997), which are two ^■ procarcinogenk; agents found ii* cannabis- smoke (MePartiand., J, ,, & Prnitt, P. L., "Alternative Therapies In H lth And Medicine ' 3(4), 57 (1999), Cannabis flavonoids thus may be modulating the therapeutic effects of TBC and CBDs by either synergistically enhancing desired piiannacologic effects or reducing ctetrimental effects.

Research indicates that the colony stimulating factor 1 receptor (CSFIR) Mnase play important roles in microglial activation and proliferation in the brain (Gomez-Nicola et aL„ 2013). Inhibition of CSF I provide beneficial effects on die progression of chronic ne rodegeneiBtiors, highlighting .the detrimental contribution of microglial piOliieiation (Gomez-Nicola D, Perry VH, Analysis of microglial proliferation n Alzheiffier's disease, Methods Moi. BioS 2016; 1303: 185-93 2013). Prolonged inlnMtai of CSFIR in APP/PSl mice by an orally available tyrosine kinase inhibitor (GW2580) was shown to result in. the blockade of microglial proliferation and shifting of the microglial

inflammatory profile to an anti-iitf!ammaioiy phenotype (Ohnos-Alonso, A., Schetters, S. T. _} Sri, S. _; Askew, . _; Mancnso, R. _; Vargas-Caballero, M., Gomez- cola, D., Pharmacological Targeting of CSFIR inhibits Microglial Proliferation And Prevents The Progression Of Alzheimer 's-Like Pathology. Brain, awv379, 2016). Targeting of CSFIR in APP PSl mice resulted in an improved performance in memory and behavioral tasks and a prevention of synaptic degeneration (Olrnos-Alonso et al, supra, 2016). Amyotrophic lateral sclerosis (ALS) is one- of the indications tha CSFIR has .been implicated in its onset, and progression, ALS is a fetal ne rodegenerati ve disease caused by the loss of sTOtofl iiT iS in me motor cortex, hraffistem and spinal cord. It manifests- wi th skeletal muscle weakness, spasticity and eventual paralysis, leading to the death of ptients by respiratory failure 3 to 5 years after, diagnosis (Bruijn, L. L Miller, T. M, &

Cleveland, D, W., Unraveling The Mechanisms Involved in Motor Neuron

Degeneration In ALS. Annual review of neurmctence 2004, 27, 723-749, 2004). tafiaamiatioa is a common netTOpa feological f aatre in several neurological disorders . ^' including ALS and the contribution of CSFIR signalling to inllanimatioii m ALS, as a pathway has been reported to control the expansion and activation of microglial cells (Martinez-Mariana, A. _s Mancuso, R., frai QS-Qiujorna, 1., Olmos-Alonso, A„ Osta, R., Perry; V. H., ... & Lopez-Vales, R,, CSFI Blockade Slows The Progression Of Amyotrophic Lateral Sclerosis By Reducing Microgliosis And invasion Of Macrophages Into Peripheral Nerves, Scientific reports _t 6, 2016). New data as such suggest, that CSF R signalling could be a novel therapeutic target m ALS ( artinez- Muri ^' ana et al, supra, 2016).

indication that CSFIR plays a role it is onset and progression (Ueda, S. ₅ Yamashita, H. , Hikiarai, R,, Sawamoio, N., Yosbida, ., & Takahashi, . ., A. Novel A792D Mutation in the CSFIR Gene Causes Hereditary Diffuse Leukoencephalopathy With Axonal Spheroids Characterized By Slow Progression. eNmixtiogicalSci, 1(1), 7-9, 2015; Rademakers, R., Baker, M., Nicholson, A. M., Rutherford, . J. ₍ Finch, N. _t Soto- Ortolaza, A. & Adamson, J., Mutations In The Colony Stimulating Factor 1 Receptor (CSFIR) Gene Cause Hereditary Diffuse Leukoencephalopailiy With Spheroids,N ^' ature genetics. 44(2), 200-205, 2012). HDLS is an. autosomal dominantly inherited centra! nervous system white matter disease with variable clinical presentations .including persoml -asd behavioral changes, dementia, depression, parkinsonism;, seizures, and others (Axelssoii R, Roytta M, Sourander , _: Akessoa HO, .Andersen O, Hereditary Diffuse Leucoencephalopathy With Spheroids, Act Fsyeliiatr Seaad Snppi , 19S4; 314:1-65. [PubMed: 6595937,2009). Given the role of CSFIR in miciogial proliferation and ^■ differentiation in the brain and the "role that microglial plays in HDLS pathogenesis, inhibition of CSFI is a potential therapeutic target for HDLS and related The casein kinase is ^' another important rou of kinases injplicaled in {fee pathogenesis of neorodegenenitive disorders including especially Parkinson's Disease aad Alzheimer's (Perez DI, Gil C, Martinez A,, Protein Kinases CK1 and C 2 As New Targets For Neurodegenerati ve Diseases, Med Res Rev, 31, 924-54, 2011 ). It has been shown that and imbalance in dopamine Ϊ and 5 receptors mediates Parkinson's Disease and the receptors are negatively regulated fey the overexpiession of casein kinase 2 (Rebhoiz, HL, Nishi, A,, Liebseher, S., Nairn, A. C, FS joSet, M,, Sc. Greengard, P., CIO Negativel Regulates Gas Signaling, Proceedings of (he National dcadmy of Sciences, 06Q$% 14096-1 101 , 2009; Gerien, C. R., Bl Dopamine Receptor Supetseasitrvity In The Dopamine-Dep!eted Striatum Animal Model Of Parkinson's Disease, The Neimscieniist, 9(6), 455-462, 2003). Casein, kinase inhibitors as such hold promise as potential therapeutic agents against neurodegenerative diseases.

The sirloins represents another class of proteins thai act like double edge swords and in some cases negatively contribute to the pathogenesis of some neiirodegeneraiive disorders. Sirtuins are a class ofenzynies believed to play a significant ro!e in diseases of aging, including type 2 diabetes and obesity. SIRT 2 is one of the seven human sirtuin enxy es. Compounds that block the activity of this enzyme could have clinical utility to treat a range of neurodegenerative such as Parkinson's Disease and Htaitisgton's Disease, Using . ^' Sl 1^ ^' mhibitor$ ^ious es ^h r^ have been able to demonstrate that -the inh bito s: have a neuroprotective effect models of Parkinson's Disease (Chen, X„ Wales, F„ Qumt L.2uo _s F„ Meniof S., Henssoo, F,, & Maxwell, M.

Bioactivity of the above-described compounds has been verified by use of kinase inhibition and histone deacetylaze assays to determine Che effect of the cannabis fiavonoids in the onset and progression of various CNS related conditions particularly Parkinson's -and Alzheimer,

Kinase inhibition assay

Cannabis flavonoids and their analogs were subjected to kinase ^' inhibition assay. The compounds were first screened a a single concentration of W μΜ i the- primary assay. Compounds inhibiting at least 70% of specific kinases were subjected to further screening to determine kd values To determine the hi values, competition, binding assays were established, authenticated and executed as described previously (Fabian et al., 2005, Kararaan. et aL 2008). For most assays, kinases were fused, to T7 phage strains (Fabian et at 2005) and for the other assays, kinases were produced in HE -293 cells after which they were tagged with DMA for quantitative PCJR detection (data not shown), la general., full-length constructs were used for small, single domain kinases, and catalytic■ domain consti¾cts for large miilti-domain kinases. The binding assays ittilized sirepta-vidm-coaied magnetic beads treated with biotih !ated small molecule ligands lor 3 .minutes at room temperature whic generated affinity resins for the kinase assays. The liganded beads were blocked with excess biotin and washed with blocking buffer (SeaB lock (Pierce), 1 % BSA, 0.05 % Tween 20, 1 mM DTT) to remove unbound ligand and to reduce non-specific phage binding. Binding .reactions were assembled by combining kinases, ligan ed aff inity beads, and test compounds in i binding buffer (20 % SeaBIoek, 0. J 7x. PBS, 0.05 % Tween 20, 6 mM DTI), Test compounds were prepared as 40x stocks in 100%

DMSO and diluted directly into the assay (Final DMSO concentration. == 2.5%), All reactions were performed in polypropylene 384- well plates in a final volume of 0.04 ml. The assay plates were incubated at room temperature with shaking for 1 hour and the affinity beads were washed with wash buffer ( lx PBS, 0,05 % Tween 20). The heads were then re-suspended in elation buffer (lx PBS, 0,05 % Tween 20, 0.5 Μ non-biounykted affinity ligand) and incubated at room temperature with shaking for 30 minutes.. The kinase concentration in the eluates wa$ measured by quantitative PCR, Kd values were determined using a standard dose response curve using the hill equation. Curves were fitted using a non-linear least square fit with the Levenberg- Marquardt algorithm. FIG.4.illustrates results of the inhibition of kinases by cannabis flavonoids and their analogs (Table 2). Si F inhibition assay

S1RT2 displays NAD+-dependent de&cetylase activity man endpoini, trypsin- coupled reaction with a ilnorogenic substrate. The deacetylation reaction is performed in 50 mM Tris-HCf, pH 8.0, 137 mM Nad, 2.7 mM KC1, 1 mM MgCIl 1 rag/ml BSA, with Ac-RH -K(Ac)-AMC and NAD- ^; - as substrates (Km: s are -200 and 500 μΜ respectively). The reaction is terminated and fluorescence signal (Ex. 360 nm/Em. 460 nm) developed. (-30 rain.) by addition of an equal volume of 2 mM nicotinamide, 16 nig/ml, trypsin in 50 mM. Tris-RCI, pH.8.0, 137 mM NaC.1, 2.7 mM .C1, 1 mM MgC12, FIG. 4 illustrates results of the inhibition o S! Ts by cannabis flavonoids and their analogs (Table 3).

FIG, 5 is the dose response, curves of compounds against Sirtuins. Overcoming the difficulty of delivering therapeutic agents to specific regions of the brain presents a major challenge to treatment of most brain disorders as ~100% of large-molecule neuroteapeutics and more than 98% of all small-molecule drags fail to cross the BBB (Pardridge 2005), Several fiavonoids, due to their low moieciilar weight and lipophilic properties, are known to cross the BBB and play significant roles in nt¾iotherap¾utic5 (lager and Saaby 201. ! , Faria et al.., _. 201 and 2014).

Preliminary studies using, the MPT? induced adtinson's model suggested that nio ^' lecules ia this invention likely crossed the BBB and have iieoropro eeti properties. Following treatment of FTP ^'■ Parkinson's induced mice with the compounds, mnnunohistcchemistry revealed increase in tyrosine hydroxylase (TH) positive cells in the br in compared to Ae control confirming the entry and

neuroprotective activity of the molecules in the brain (Data not shown).

A .method for isolating the specific cannabis-based fiavonoid pharmaceutical compositions from raw plant materia! is also disclosed.

At step 10 an appropriate amount of plant biomass is collected. For present purposes, Cannabis s Uv plants were collected by hand. See, Radwan, M. ., ElSohly, M.A., Slade, D., Ahmed, S.A, Wilson, L, El~Aify, A.T., Khan, LA., Ross, S,A„ 2008a. Non-cannabinoid constituents from a high potency Cannabis sativa variety.

The collected plant material was air dried under shade and pul verized, int powder, A t step 20 the powder is subjected to supercritical fluid extraction (SFE) by which carbon dioxide (CO") is used for separating one component (the extractam) from -another (the matrix). The extract is evaporated: to dryne resulting- in green residue.

At step 30, for experimental purposes, a bioassay-guided fractionation was employed, using a standard protocol to isolate a pure chemical agent from its natural origin. This entailed a step-by-step separation of extracted components based on differences in their physicochemical properties, and assessing ail their biological activity. The extracted components may, for example, be fractionated by dry colnmn flash clnmnaiogiaphy on Si gel using hexan©€H2G2/ethy! acetate and mixtures of increasing polarity to yield different fractions. The sample is then degassed by ultra- sotiication to yield an insoluble solid, which solid is then filtered. The sample ma then be subjected to high performance liquid chromatography (HPLC) using a column Phenomenex Luna™ CI 8, S m, 2*50mm; eluent, acetonitriie with 0.05% M.eOH to confirm the presence of the various fractions.

At step 40, bioaetivity of the extracts were verified in a kinase inhibition assay as described above. This identified the bioactive flavorioids from ail the supercritical fluid extracts (SFE). As reported previously, the identified caunabis-based flavoooid extracts showed, activity against several kinases implicated in the pathogenesis of C.NS disorders.

The next step was io identify the cannafeis-based flavonoid constituents responsible for the observed kinase- inhibitory -acuiti s and to- further isolate them.

At step 50 Nuclear Magnetic esonance Spectroscopy and mass spectrometry

( I/MS) was performed and .the interpreted spectra were consistent with cannabis- based f!avoaoid compositions inclndin¾- Flavone, as identified above,, and as shown ^' in step 60. The bioactive cannabis-based flavonoid extracts found bioactive for tire

prevention and treatment o CNS disorders had the structure of the general formula of FIG. i .

Given the known structure of the general fonnuia of FKl, I, a method for synthesizing the same becomes possible. The bioactive eannabis-based flavonoid pharmaceuticai composition may be synthesized, by the phenylpropanoid metabolic pathway in which tSie amino acid phenylalanine is used to produce 4-cotttBaroyt-CoA. li should now be apparent that the above-described invention provides a pharmaceutical composition for the prevention and treatment of disease with specific eannabis-based -flavonoid compounds selected from, mon the groups of A genio, CamiOavin A,.
