Definitions
- This invention is related to obtaining a new active ingredient that can be used as a nutritional supplement or as a pharmaceutical or cosmetic product, with a view to preventing and / or treating the inflammatory processes and oxidative stress that accompany the aging process and numerous pathologies. , such as benign prostatic hyperplasia (BPH), prostatitis and osteoarthritis, among others, as well as being related to the process of obtaining said active ingredient from green or ripe fruits of Acrocomia crispa or Acrocomia aculeata, both from the Arecaceae family.
- BPH benign prostatic hyperplasia
- prostatitis and osteoarthritis among others, as well as being related to the process of obtaining said active ingredient from green or ripe fruits of Acrocomia crispa or Acrocomia aculeata, both from the Arecaceae family.
- This active ingredient includes a mixture of linear fatty acids between 6 and 28 carbon atoms, mostly saturated ones: C 8 : 0 , Cio : o, Ci2: o, C14.0, Ci6 : o and Ci8: o, and the unsaturated: Ci6: i, Ci 8: i, Ci8: 2 and C ⁇ es, and may also contain sterols and high molecular weight fatty alcohols.
- the process of obtaining this active ingredient starts from drying and grinding the fruits, and can include partial or total hydrolysis (enzymatic, basic or acidic) of both the plant material and its lipid fraction with subsequent recovery of fatty acids; Selective extraction of the lipid fraction can be performed with organic solvents or by extraction with supercritical fluid. Both procedures, with and without hydrolysis, allow to obtain active ingredients with similar pharmacological and physiological effects.
- the present invention relates to the food and pharmaceutical industry, as the active ingredient obtained can be used as such or in doses between 50 and 1000 mg, as part of nutritional, cosmetic and / or pharmaceutical formulations for prevention and / or the treatment of inflammation and oxidative stress, including BPH, prostatitis and osteoarthritis.
- Inflammation is the vascular and cellular response of tissues to infection, irritation or the presence of foreign substances. This is one of the mechanisms of The body's most important defense, but when the response is increased too much it can be harmful and in some cases fatal. Inflammation is an important etiological factor in the development of chronic diseases such as osteoarthritis, BPH, prostatitis, inflammatory bowel diseases, cancer, among others. The frequency of suffering from chronic inflammatory diseases increases with age and with the increase in life expectancy.
- AA Arachidonic acid
- fatty acid 20 carbon atoms (5, 8, 11, 14-eicosatetraenoic acid) obtained from food or by conversion of linoleic acid
- phospholipase A2 an enzyme that is activated by physical, chemical or biological stimuli
- eicosanoids The metabolites derived from AA, called eicosanoids, are synthesized through the cyclooxygenase (COX) enzyme (COX-1 and COX-2) pathway, which allows the generation of prostaglandins, and thromboxanes, and through the pathway of lipoxygenases (LOX), a family of cytosolic enzymes 5-LOX, 15-LOX and 12-LOX, which allow the generation of leukotrienes and lipoxins (D ⁇ az, 2001; Gajraj, 2003). Eicosanoids can intervene in the different phases of inflammation, they are in the inflammatory exudate and their synthesis is increased in the places of inflammation.
- COX cyclooxygenase
- COX-1 and COX-2 cyclooxygenase
- LOX lipoxygenases
- Inflammation is classified, according to the intensity and duration of the response, into acute or chronic.
- Acute inflammation is of short duration and involves three fundamental mechanisms: vasodilation, increased capillary permeability and leukocyte migration (mainly of neutrophils) from the blood to the inflammatory focus, although it also includes phagocytosis and cell regeneration and repair (Gallin et al. 1992).
- the characteristic signs of acute inflammation are: flushing, swelling, heat, pain and loss of function (Parakrama and Clive, 2005; Porth, 2007).
- lipid peroxidation (PL) of polyunsaturated fatty acids (PUFA) by enzymatic route produces radical species of lipid origin, which occur in this case, so controlled, by the action of enzymes involved in cellular metabolic pathways.
- LOX lipid hydroperoxides
- COX hydroxylated products
- the organic hydroperoxides formed are quite stable structures, they can decompose in the presence of transition metals (copper and iron ions) and generate a complex mixture of secondary peroxidation products, such as hydrocarbon gases (ethane and pentane) and aldehydes (malondialdehyde and 4-hydroxynonenal), which can consequently damage cell structure (Halliwell, 1995).
- transition metals copper and iron ions
- secondary peroxidation products such as hydrocarbon gases (ethane and pentane) and aldehydes (malondialdehyde and 4-hydroxynonenal)
- NSAIDs non-spheroidal anti-inflammatory drugs
- IVAs spheroidal anti-inflammatory drugs
- AD adverse experiences
- NSAIDs The mechanism of action of NSAIDs is based on the inhibition of the enzymatic activity of COX. NSAIDs are classified as: non-selective or nonspecific (inhibit COX-2 isoforms 1 and 2) and selective COX-2 (Sciulli et al. 2005).
- Non-selective NSAIDs acetylsalicylic acid, indomethacin, naproxen, ibuprofen, diclofenac, among others
- EAs that produce the gastrointestinal tract, becoming severe if administered for prolonged periods or in elderly patients advanced They can also cause elevated blood pressure and nephrotoxicity (Garc ⁇ a and Hernández-D ⁇ az, 2004; Lanas and Ferrandez, 2006).
- COX-2-specific NSAIDs are newer-generation drugs and their high selectivity for isoform 2 supports better gastric tolerability (Silverstein et al. 2000). However, its use is associated with the occurrence of severe cardiovascular EAs that have even led to the withdrawal of rofecoxib and valdecoxib from the market (Blandizzi et al. 2008).
- IEAs prednisone, prednisolone, dexamethasone, among others
- gastrointestinal AD hyperglycemia
- bone osteoporosis and osteonecrosis leading to various fractures
- Cushing's syndrome arterial hypertension
- petechiae and ecchymosis facial erythema, vertigo and headache
- dual anti-inflammatories (5-LOX and COX inhibitors) reduce the progression and development of chronic inflammatory processes without producing the typical gastrotoxicity of nonspecific NSAIDs (Whitehouse and Butters, 2003; Whitehouse, 2004).
- BPH Among the pathologies that involve chronic inflammation is BPH, since it is known that infiltration of inflammatory cells in the prostate is an important etiological factor in its development (Roehrborn, 2008; Zhu and McGinley, 2009) so substances that Possessing an anti-inflammatory effect could be useful in the treatment of this disease. BPH is, together with cancer and prostatitis, among the most relevant pathological processes that affect the prostate and decrease the quality of life of the adult male population, mainly in men over 50 years (Fernández and Pereira, 2008; Alcaraz et al., 2008).
- BPH is the non-malignant and uncontrolled growth of the prostate, a gland that, when located at the exit of the bladder and surrounding the first part of the urethra, tends to cause obstruction when it grows. Consequently, the majority of patients with BPH present with symptoms of the urinary tract (STBU) such as urinary retention, decreased urine volume and urination pressure, increased latency to urinate, irritation, bladder incontinence and nocturia (Nix and Carson, 2007; Roehrborn, 2008; Zhu and McGinley, 2009).
- STBU urinary tract
- the etiology of BPH fundamentally involves a hormonal factor consisting in the increase in the conversion of testosterone to dihydrotestosterone (DHT) by the action of prosthetic 5-a-reductase that triggers cell proliferation and enlargement of the prostate (static component of BPH), and for a non-hormonal component consisting of the increase in the tone of the smooth muscle of the bladder and prostate (dynamic component) regulated by adrenoceptors (ADR) -al (Nix and Carson, 2007; Zhu and McGinley, 2009). While the hormonal component plays a crucial role in the development of hyperplasia and in increasing the size of the prostate, increasing the tone of the urogenital smooth muscles is essential in the development of STBU (Roehrborn, 2008).
- DHT dihydrotestosterone
- ADR adrenoceptors
- the treatment of BPH includes, depending on the degree of progression of the disease, from careful surveillance to surgery, although the most commonly used is the pharmacological one, which is mainly based on using prostatic 5a-reductase inhibitors and antagonists of ADR-cc1 (Doggrell, 2004; Roehrborn et al., 2008; Schwinn and Roehrborn, 2008).
- ADR-a1 antagonists (Alfuzosin, doxazosin, prazosin, terazosin, tamsulosin) usually relieve symptoms quickly, but do not affect prostate size and can cause AD such as orthostatic hypotension, fatigue, dizziness, ejaculatory dysfunction and alterations.
- the mechanism of action of the ELSr is multifactorial and involves several of the aforementioned factors, such as the inhibition of 5a-reductase (Raynaud et al., 2000; Abe et al., 2009), the antagonism of ADR-a1 (Gerber et al., 2001; Debruyne et al., 2002; Abe et al., 2009), anti-inflammatory activity by inhibition of COX and 5-lipoxygenase (5-LOX) enzymes (Mogul et al., 2000; Potenziani , 2003; Raman et al., 2007; Curt ⁇ s, 2008) and antioxidant effects (Henry, 2000; Perona, 2005; Chapkin et al., 2007), among others. Although its preclinical toxicology data are scarce, the ELSr is well tolerated, and has a low frequency of AD (Rockville, 2005).
- D004 Another lipid extract with potentialities in the treatment of BPH, D004, has recently been developed from fruits of Roystonea regia.
- the mechanism of action that underpins its efficacy in PH models is multifactorial, and involves the competitive inhibition of prosthetic 5th reductase, and the non-competitive antagonism of the contractile response of ADR-a mediated prosthetic tissue.
- D-004 produces anti-inflammatory pleiotropic effects (associated with the inhibition of 5-LOX) and antioxidants (both in normal prostate tissue and in hypertrophy), which could potentially contribute to its effectiveness (Menéndez, 2006; Pérez, 2008).
- osteoarthritis the most common degenerative arthritis, which is characterized by a disorder of the normal balance between the synthesis and degradation of the cartilaginous matrix (constituted by proteoglycans, collagen and water), destruction of the cartilage, alteration of the subchondral bone and subsequent inflammatory reaction, in which the cartilage not only does not regenerate later, but can disappear (Little, 2008).
- OA OA involves all components of the joint, not only cartilage, since structures such as subchondral bone, ligaments, joint capsule, synovial membrane, periarticular muscles, menisci and sensory nerve endings participate in the inflammatory process (Lotz, 2010; Heinegard, 2011).
- the response of the subchondral bone in OA includes the production of "new bone” that leads to the development of marginal osteophytes that project outside as nodules that can be inflamed secondarily or as bone growths capable of irritating neighboring structures (Buckland-Wright, 2004; Little, 2008).
- NSAIDs drugs that improve pain and functional disability
- IEAs irritable bowel syndrome
- NSAIDs produce various EAs.
- Antiresortives have also been used in the management of OA, having shown that alendronate and estrogens significantly reduce subchondral bone lesions in elderly women with knee OA compared to untreated elderly women (Carbone, 2004), supporting the concept that the OA involves every joint organ (cartilage and bone).
- the process for obtaining the active ingredient object of the present invention is based on the use of green or ripe fruits of the species A. crispa and / or A. aculeata, both of the Arecaceae family. These fruits are dried in environmental conditions or in stoves and milled in a knife mill, hammer or laminator until a particle size ⁇ 3 mm is obtained, and from this dry and ground material an active ingredient of a lipid nature composed mostly of Free fatty acids, although it can also contain lower sterile proportions and high molecular weight aliphatic alcohols.
- an enzymatic (total or partial) hydrolysis can be applied, basic or acidic, with a subsequent recovery of the fatty acids, or the active ingredient can be obtained by selective extraction with organic solvents (hydrocarbons, alcohols, ethyl acetate, acetone or mixtures thereof) or by extraction with supercritical fluid. Hydrolysis can be applied directly to the ground plant material or to the lipid active ingredient obtained from it.
- the dried and ground plant material is subjected to selective extraction with organic solvents, with subsequent filtration and removal of the solvents with reduced pressure heat, or extraction in supercritical conditions.
- a conventional liquid solid extractor can be used, such as a stirred reactor or a soxhlet type extractor, where fatty acids (in the form of acylglycerides, ethyl esters and to a lesser extent free) are separated from the components that they are accompanied in the plant material by selectively dissolving in a suitable solvent, sought between alcohols of 1 to 3 carbon atoms (methanol, ethanol, 2-propanol) and hydrocarbons of 5 to 8 carbon atoms (pentane, isopentane, hexane, heptane and octane), ethyl acetate, acetone or mixtures thereof, and can also be obtained by supercritical extraction with CO 2 .
- the extraction with ethanol favors the obtaining of ethyl esters, present in a small proportion in the plant, which is favored in an acid medium.
- an enzymatic hydrolysis (with lipases) is applied, basic (with alkaline or alkaline toric hydroxidps, organic, or ammonium hydroxide) or acid (with hydrochloric, citric or sulfuric acid).
- Said hydrolysis which can be total or partial, can be applied to the ground plant material or to the lipid extract obtained therefrom and subsequently the free fatty acids are recovered.
- basic hydrolysis is applied, the fatty acids are released in an acidic medium with stirring (using dilute hydrochloric, citric or sulfuric acid) and separate from the aqueous phase forming an upper oil phase, which is washed with treated and dried water. with heat under reduced pressure.
- This method achieves between 10 and 40% yield from the dried and ground plant material, resulting in obtaining this active ingredient, which is mainly composed of free or esterified linear acids such as acylglycerides or ethyl, mainly acids saturated with 8, 10, 12, 14, 16 and 18 carbon atoms, as well as with unsaturated 16 and 18 carbon atoms, and may also contain sterols and fatty alcohols.
- the proportion of fatty acids (free or esterified) in this mixture is presented in Table 1.
- Oleic Acid (Ci8; l) * 33.8 31.7 * The mixture of C 18: i oleic acid, Ci8: 2 linoleic acid and Ci 8: 3 linoleic acid is determined and reported as oleic acid.
- Example 1 The effect of the active ingredients referred to in Example 1 was evaluated in a chronic inflammation model (cotton granuloma) for which they used male Sprague Dawley rats (250-270 g) adapted for 7 days to laboratory conditions. After the adaptation period the rats were distributed randomly in different groups and anesthetized with sodium thiopental (30 mg / kg, ip). The back area was disinfected with 70% alcohol and an incision was made in the lateral back half, creating a subcutaneous tunnel using blunt tweezers, where a 50 mg sterile cotton speck was placed. The wound was sutured and a local antiseptic was applied.

- rats were distributed randomly in different groups and anesthetized with sodium thiopental (30 mg / kg, ip).
- the back area was disinfected with 70% alcohol and an incision was made in the lateral back half, creating a subcutaneous tunnel using blunt tweezers, where a 50 mg
- the rats were sacrificed in an ether atmosphere, the granulomas were carefully dissected and placed in an oven at 60 ° C for 24 hours, until they reached a constant weight.
- the weight of the cotton speck 50 mg was subtracted from this value.
- the degree (%) of inhibition was expressed by taking the weight of the granuloma of the control group as 100% inflammation.
- the extracts of the fruits of A. crispa and A. aculeata were emulsified in a Tween-20 / H 2 O solution.
- the rats were randomly distributed in 7 groups (10 rats / group): a control treated with the vehicle, 3 groups treated with extracts of A. crispa and 3 with extracts of A. aculeata (25, 200 and 500 mg / kg) respectively.
- Administration was performed by gastric intubation (5mL / kg) during the 6 days following the implantation of the cotton speck. Subsequently, the granuloma dry weight was quantified.
- the comparison between the control and treated groups was made with the Mann Whitney U test.
- Example 2 The effect of the active ingredients cited in Example 2 was evaluated in a model of acute inflammation (pleurisy by carragenin single dose in rats).
- Male Sprague Dawley rats (190-290 g weight) were used, which were adapted for 7 days to laboratory conditions. After the adaptation period the animals were randomly distributed in different groups. Subsequently, the rats were anesthetized in ether atmosphere, an incision was made in the lateral dorsum and 0.3 ml of the 1% carrageenan solution in saline solution was injected into the pleural cavity. Five hours after the induction of inflammation, the rats were sacrificed to obtain pleural exudate, for which they were anesthetized in an ether atmosphere and bled by the abdominal aorta.
- the pleural cavity was opened and 1 ml_ of 3.15% sodium citrate was added, which was homogenized with the exudate, which was carefully extracted using an automatic pipette. Once collected, it was transferred to a graduated plastic tube to determine the volume of exudate (VE). Subsequently, the activity of myeloperoxidase (MPO) in the exudate was determined.
- MPO myeloperoxidase
- the extracts of the fruits of A. crispa and A. aculeata were emulsified in a Tween-20 / H 2 O solution, being administered as single doses by gastric intubation (5mLJkg).
- the rats were randomly distributed in 8 groups (10 rats / group): a negative control to which saline solution was injected into the pleural cavity and 7 groups to which pleurisy was induced by carrageenan injection: a vehicle-treated positive control, 3 treated groups with extracts of A. crispa and 3 with extracts of A. aculeata (25, 200 and 500 mg / kg) respectively.
- the comparison between the control and treated groups was made using the Mann Whitney U test.
- the carrageenan injection produced a significant increase in the VE and the enzymatic activity of the MPO in the exudate with respect to the negative control group (Table 8).
- Administration of the object of the present invention 25, 200, 500 mg / kg orally (single dose) was effective in reducing the VE and inhibiting the enzymatic activity of the MPO in a significant and dose-dependent manner, so that the highest dose tested (500 mg / kg) reduced the VE by more than 50% compared to the positive control, and inhibited the activity of the MPO.
- results obtained demonstrate the efficacy of the extracts of the fruits of A. crispa and A. aculeata in the carrageenan pleurisy model in rats, observing a dose-dependent reduction of the VE and the activity of the MPO, showing its potential as an anti-inflammatory.
- Table 8 Effect of oral treatment with the extracts of the fruits of A. crispa and A. aculeata on the formation of edema and increased MPO activity in the carrageenan pleurisy model in rats.
- mice young adult male OF- mice (20-30 g) adapted for 7 days to laboratory conditions were used. After the adaptation period the mice were randomly distributed into 6 groups: a negative control + vehicle, a positive control (treated with the vehicle + application of Xylene); and 4 treated with the extracts of A. crispa, A. aculeata, ELSr and D004, to which xylene was applied, all administered at doses of 400 mg / kg. All treatments were administered 1 hour before edema induction.
- Edema induction was performed, topically applying 30 ⁇ L ⁇ of pure xylene on the dorsal surface of the right ear of the mouse. Two hours later the edema was quantified, for which the mice were anesthetized in ether atmosphere and sacrificed by cervical dislocation. Both ears were cut and weighed on an analytical balance (Mettler Toledo). Edema formation was calculated by the difference in weight (mg) between the right ear (with edema) and the left ear (without edema) ( ⁇ ). The comparison between the control and treated groups was made using the Mann Whitney U test.
- Topical application of xylene significantly increased the difference in weight between both ears, indicative of edema formation compared to the negative control group (table 9). All treatments significantly inhibited the increase in edema.
- Example 4 To evaluate the antioxidant effect of the active ingredients referred to in Example 4, male Sprague Dawley rats (200-250 g weight) adapted for 7 days to laboratory conditions were used. After completing their adaptation period, the animals were randomly distributed in different groups, anesthetized in ether atmosphere and bled by the abdominal aorta. Blood was collected with EDTA (10%) (final concentration: 1mg / ml of blood). The plasma was obtained by centrifugation at 3000 rpm for 10 min and was used to determine the concentrations of malondialdehyde (MDA) (product of PL) and sulfydryl groups (SH) (product of protein oxidation).
- MDA malondialdehyde
- SH sulfydryl groups
- the extracts of the fruits of A. crispa and A. aculeata were emulsified in a Tween-20 / H2O solution.
- the rats were randomly distributed into 9 groups (10 rats / group): a vehicle-treated control, 4 with A. crispa extracts and 4 with A. aculeata extracts (5, 25, 50 and 200 mg / kg), respectively .
- the treatments were administered by gastric intubation for 30 days. Subsequently, the plasma concentrations of MDA and SH were quantified.
- the comparison between the control and treated groups was made using the Mann Whitney U test. As can be seen in Table 10, both extracts reduced the plasma figures of MDA and SH in a marked and significant way. With A.
- Example 5 To evaluate the effect of the active ingredients described in Example 5, they were emulsified in a Tween-20 / H2O vehicle and their effects on an HP model in rats were investigated.
- male Sprague Dawley rats 300 - 360 g adapted for 7 days to laboratory conditions were used, which were randomly distributed in 8 experimental groups: a negative control + (vehicle) and 7 groups to which they were induced HP with testosterone injection (4 mg / kg), a positive control, which only received the vehicle, and another 6 treated: 3 of them with the extract of the fruits of A. crispa and 3 with that of A. aculeata ( 50, 200 and 400 mg / kg).
- Testosterone propionate was dissolved in vegetable oil and injected daily, sc for 14 days.
- Oral treatments were administered. by gastric intubation (5mL / kg), once a day, for 14 days. Subsequently, the rats were sacrificed under anesthesia, bled, he opened his abdomen through an incision in the ventral midline, his prostates were separated from the bladders, they were removed and weighed. The comparison between the control and treated groups was made with the Mann Whitney U test.
- Testosterone injection produced a significant increase in prostate weight and prostate weight / body weight ratio compared to the negative control group (Table 11).
- the administration of the extracts of the fruits of A. crispa and A. aculeata orally for 14 days significantly reduced the increase in the size of the prostate induced by the injection of testosterone ( ⁇ 44% with the highest dose tested).
- the effect of the active ingredients referred to in example 1 on an osteoarthritis model was evaluated in the mono-iodoacetate-induced arthritis (MIA) model in rats.
- MIA mono-iodoacetate-induced arthritis
- Male Sprague Dawley rats with body weight between 150 and 175g adapted for 7 days were adapted to the laboratory conditions, which were randomly distributed in 8 experimental groups: a negative control + (vehicle) and 7 groups to which they were induced damage with MIA; a positive control, which only received the vehicle, and another 6 treated: 3 of them with the extract of the fruits of A. crispa and 3 with that of A. aculeata (100, 200 and 400 mg / kg).
- the left knee joint was removed and kept in formalin for 24 hours. It was then decalcified in 0.5 M disodium EDTA (pH 7.4) at 4 ° C for 4 weeks. Upon completion of decalcification the joint was sectioned in the longitudinal plane to obtain 2 halves, being subsequently included in paraffin, cut and colored with Hematoxylin and Eosin and toluidine blue to analyze the cartilage.
- Cartilage damage was assessed according to its depth and extent using the modified Mankin score, as follows: • Depth (0-5): 0- normal, 1- minimum, affecting only the surface area, 2- slight invasion of the upper middle zone only, 3- moderate invasion also in the middle zone, 4- marked invasion to the deep zone, but not to the dividing line or interphase existing between the uncalcified and calcified cartilage (tidemark) and 5- severe degradation from all the thickness to the dividing line between the non-calcified and the calcified cartilage.
- Matrix staining reduction (0-4): 0 - normal / slight staining reduction, 1- reduced coloration in the radial layer, 2-reduced coloration in the inter-territorial matrix, 3- coloration present only in the pericellular matrix and 4- absent coloration.
- Cartilage changes (0-6): 0-normal, 1-irregular surface, including fissures in the radial layer, 2 - pannus, 3 - absence of superficial layers of cartilage, 4 - slight disorganization (absent cell columns, some conglomerates small superficial), 5- fissure in the calcified cartilage layer, and 6- disorganization (chaotic structure, conglomerates and osteoclastic activity).
- Cellular abnormalities (0-3): 0- normal, 1- hypercellularity, including small surface conglomerates, 2- conglomerates and 3- hypocellularity.
- Loss of cortical or trabecular bone 0- normal, 1- minimal loss of cortical bone in a few places, 2- slight loss of cortical or trabecular bone, 3- moderate loss of bone in many places and 4 - marked loss of bone in many sites with fragmentation and penetration throughout the thickness of the inflammatory process or the formation of pannus in the cortical bone.
- Osteoclasts (0-4): 0 -normal (essentially non-osteoclasts), 1- few osteoclasts (aligned in 5% of the majority of the affected bone surface), 2 -some osteoclasts (aligned between 5 and 25 % of most affected bone surfaces), 3- many osteoclasts (aligned between 26-50% of most affected bone surfaces) and 4-large number of osteoclasts (aligned on more than 50% of the affected bone surface ).
- the mean scores of the histological parameters studied were calculated.
- the histological score was calculated as the average of all the histological variables evaluated.
- the comparison between the control and treated groups was made with the Mann Whitney U test.
- MIA mono-iodoacetate
- MIA mono-iodoacetate
- MIA mono-iodoacetate
- Example 1 Several formulations with the active ingredient referred to in Example 1 were developed in doses between 50 and 1000 mg, as presented below: tablets containing corn starch, lactose, talc, gelatin, croscarmellose sodium, magnesium stearate, carboxymethylcellulose; hard capsules and soft gelatin capsules.
