Definitions
- the present invention relates to the field of the pharmaceutical industry and medicine, more specifically with the use of secretagogue peptides which, administered in a pharmaceutical composition repeatedly, prevent and eliminate the deposits of pathological fibrotic material in internal parenchymal tissues such as liver, lungs, esophagus, small intestine, kidneys, blood vessels, joints, in addition to systemic forms of cutaneous fibrosis of any etiopathogenesis.
- Fibrosis processes are a set of pathological entities of a mono-organic or systemic nature that are characterized by the abnormal deposition of extracellular matrix in the parenchyma of almost all internal organs, blood vessels, or skin. These are considered as the result of complex processes of auto-immune basis or interstitial responses to prolonged imitative and inflammatory events.
- excessive deposition of collagen material occurs in the parenchyma by effector interstitial cells, or from the stromal material that expands and obliterates the functional tissue.
- the effector cells of these processes are of mesenchymal origin and are usually quite specific according to the affected tissue.
- myo-fibroblasts are accused of pathological fibrosis processes.
- TGF- ⁇ transforming growth factor beta
- CTGF connective tissue
- PDGF growth factor derived from platelets
- liver fibrosis When liver damage is caused, the inflammatory response and the remodeling of the extraceiular matrix (ME) restore the normal function and architecture of this organ. However, when the damage persists, there is an imbalance between the factors that try to repair and reach the resolution of the problem causing an alteration in the regulation of the ME and causing the excessive synthesis of its components.
- the liver is the main organ involved in the regulation of metabolism, in the process of blood filtration and in hormonal regulation. Hepatic starred cells (HSC) are located in the space that forms between endothelial cells and hepatocytes, called the Disse space or sinusoidal space, from where they surround the endothelial cells with their long cytoplasmic processes.
- HSCs are able to synthesize and secrete components of ME and represent an important source in fibrotic processes. These cells are characterized by the storage of retinyl esters, the synthesis of growth factors and other cytokines, in addition to their role in the regulation of sinusoidal blood flow.
- the HSCs can pass from a quiescent state to an active state that is induced by the paracrine secretion of inflammatory cytokines, by the production of reactive oxygen species or by changes in the structure of the ME that cause changes in the cellular phenotype.
- HSCs differentiate to myofibroblasts by acquiring an elongated form, express smooth muscle ⁇ -actin and lose stored retinol.
- HSCs acquire new properties that help them maintain and amplify the inflammatory response: proliferative capacity, contractibility, cytokine production and mainly the synthesis and secretion of components of ME.
- TGF- ⁇ synthesized mainly in the activation phase by Kupffer cells; in the perpetuation phase, the TGF- /? It is mainly produced by activated HSCs perpetuating their activation.
- any of the forms of fibrotic induration of the liver is Incompatible with life (Hepatic Failure. Last Updated: September 3, 2004.
- Pulmonary fibrosis is a slowly progressive disease that includes a diverse group of entities. Histologically, it is characterized by a temporal heterogeneity of the lesions, predominantly those of myofibroblasts. Although the sequence of events in the pathogenesis of pulmonary fibrosis is well documented, there is little information on the exact mechanisms involved in the initial damage. It is possible that immunological phenomena are important, especially autoimmune. Genetic factors must also play some role. Microscopically, a constant feature is the hyperplastic change in alveolar epithelial cells (type 2 pneumocytes) with prominent nucleoli and cytologic atypia, which often mimic a viral infection. Ultrastructurally, it is possible to find intranuclear tubular inclusions.
- TGF- ⁇ is involved as one of the main cytokines that orchestrate the process.
- Myo-fibroblasts are the effector matrix-producing cells.
- ES Systemic sclerosis
- T and B lymphocytes Functional alterations in these cells cause the triad characteristic of pathological changes in ES: progressive cutaneous and visceral fibrosis, obliteration of the lumen of small arteries and arterioles, and abnormalities in The immunity
- the alterations in the humoral and cellular immunity cause the production of numerous antibodies, some of which are highly specific for the disease, the chronic infiltration of mononuclear cells in the affected tissues and the dysregulation of the production of lymphokines and growth factors.
- fibronectin 3
- the fibroblasts of patients with ES express high levels of receptors for TCF-beta on their surface, which may be responsible for the increase in the signal induced by TGF-b and the increase in collagen production (30). This disease is also fatal and incurable (Steen V. Targeted therapy for systemic sclerosis. Autoimmun Rev. 2006 Feb; 5 (2): 122-4.)
- Diabetic Nephrosclerosis or Diabetic Nephropathy Almost all diabetic patients develop greasing of the glomerular and tubular basement membranes 2 or 3 years after the diagnosis of the disease. Some of them will develop glomerular mesangium expansion and interstitial fibrosis, the pathological marks of progressive diabetic nephropathy. Over time, the nephropathy evolves and clinically manifests as the appearance of proteinuria, hypertension and renal failure. There is a good correlation between the expansion of the region of the mesangium, the severity of interstitial fibrosis and arteriosclerosis, with the decrease in the glomerular filtration rate.
- the disease is a pathological scar of the penile albuginea that can cause the organ to retract, and in erection, curvature and retraction.
- the majority of the authors agree that the fibrotic degeneration of the tunica albuginea is preceded by an inflammatory phenomenon that could be triggered by a vasculitic, immunological process, trauma, or collagenopathy .
- a first invasion period is described where the fibrotic plaque can progress silently denoting the curve or retraction of the penis, presenting pain in the erection or during the penetration. The predominant symptoms are those caused by fibrosis.
- TGF-beta is invoked as an inducing or amplifying agent of the molecular basis of the disease (Jakut M. New discoveries in the basic science understand the Peyronie's disease. Curr Urol Rep. 2004 Dec; 5 (6): 478-84)
- vascular disease of the brain has been identified in brains for example of patients suffering from Alzheimer's disease as a marker that can represent an important pathogenic factor in this disease and other forms of dementia.
- the laminar and regional distribution of vascular lesions correlates with the presence of neurofibrillar clews and senile plaques. More than 100 years ago, morphological abnormalities were described for the first time in the cerebral vessels of the elderly, which consisted of stiffness, tortuosity and curling. Less than 20 years ago these notes have received full support while it has been described that the capillaries of the senile hippocampus distorted more with age than the great vessels.
- the thickening of the basement membrane and the collagen deposits are similar in rats and humans with age and it is considered that these processes of degeneration fibrotic sclerosis of the cerebral microvasculature is the anatomical basis of dementia processes in general. These diseases are clinically worsened in that the cerebral circulation is hindered by the occlusion of the arteriolar networks and end up causing the absence of all life. of coherent social relationship and cognitive activity.
- the role of vascular disease in the pathogenesis of dementia is currently being reassessed while it is suggested that more than 50% of patients with dementia have some stigma of cerebral vascular disease.
- Beta amyloid is one of those proteins that acts in the formation of extracellular brain deposits as it ages. Alzheimer's dementia has an insidious onset with a progressive decline of higher mental functions, affecting fixation and evocation memory. The neuropathological findings are reflected in the accumulation of neuritic plaques and neurofibrillary tangles in vulnerable areas of the brain and brain stem.
- the plates contain a compact nucleus of beta-amyloid, an oligopeptide derived from the precursor of the beta-amyloid protein.
- the risk to develop a dementia is strongly associated with the polymorphism of the apolipoprotein E. the brain, Apo-E interacts with beta-amyloid, and Apo-E4 is associated with an increased deposit of beta-amyloid and an increased number of neurofibrillary tangles.
- Both the attention and the processes of memory and learning are the points of affectation of brain functions most strikingly affected in Alzheimer's disease as a model of demential diseases that occur with accumulation of beta-amyloid.
- the beta-amyloid protein has necrogenic effects on brain cells, mediated by the action of free radicals.
- the deposit of beta-amyloid in the cerebral parenchyma is a distinctive fact of the pathogenesis of Alzheimer's disease, although it also occurs to a lesser extent in normal aging.
- the reduction of the synthesis of the neurotoxic form of beta-amyloid protein can attenuate the process that contributes to neuronal damage in Alzheimer's disease.
- its elimination of the brain and its subsequent excretion would contribute to the improvement of the superior nervous functions of the patients.
- Alzheimer's disease severely impairs the patient's quality of life, and has no cure until now Gurol ME. Plasma beta-amyloid and white matter lesions in AD, MCI, and cerebral amyloid angiopathy.

- Example 5 Effect of the pharmaceutical composition based on GHRP-6 in the control and elimination of the accumulation of beta-amyloid protein in the brain.
- the objective of this study was to evaluate the influence of prolonged administration (8 weeks) of GHRP-6 on brain biochemical and morphological markers, indicators of the progression of damage to the central nervous system, in transgenic mice for the precursor protein of the beta-amyloid
- APP transgenic mice were acquired that overexpress the amyloid beta precursor protein; male and 20-25 grams in weight.
- mice were sacrificed for overdose of anesthesia and prefused in-situ with saline.
- the brains were removed and a cerebral hemisphere was frozen in dry ice and the contralateral fixed in a 4% solution of neutral para-formaldehyde.
- the samples were subjected to cryo-cuts of 10 microns and colored with H / E, Congo Red or incubated with an antibody that specifically recognizes beta-amyloid.

- Table 15 compiles all the results of the parameters studied to characterize the effect of long-term treatment with the pharmaceutical composition containing GHRP-6. Note that the results refer to the counting of digital images of a single cerebral hemisphere. To overcome this limitation the counts were performed blindly by three different observers and the results shown correspond to 5 sheet readings. Table 15. Effect of the pharmaceutical composition containing GHRP-6 in the control of amyloid accumulation and brain biochemistry.
- the pharmaceutical composition containing GHRP-6 has a favorable impact in the control of the accumulation of amyloid material in its various forms in the brain, as well as in the correction of the organ's metabolism. There is a marked effect given by the reduction of amyloid deposits, and reduction of plate size. The marked effect of reducing the accumulation of myo-inositol establishes the evidence of a correction of biochemical routes, of greater assimilation of energy, and of better nutrition of neurons. This can have a favorable clinical impact on the control of brain aging.
- Table 16 the favorable effect of the pharmaceutical composition containing GHRP-6 in the control of lipid peroxidation in the brain of transgenic animals for Alzheimer's disease is demonstrated. Again this evidence suggests the favorable effect of this composition to control one of the processes most responsible for the deterioration of nerve tissue in diseases and during aging.
- mice 18-20 month old male mice were used when they already had symptomatic evidence of the disease.
- the animals were randomized and assigned to the following experimental and treatment groups: A - placebo group that received physiological saline. B - group treated with 100 ⁇ g / kg of GHRP-6. C - group treated with 100 ⁇ g / kg of GHRP-2. D - group treated with 100 ⁇ g / kg of Ghrelin. E- group treated with 100 ⁇ g / kg Hexarelina.
- the treatments were carried out twice in the week and for 16 weeks, intra-peritoneally. Concluded the treatments, regardless of the clinical improvement evidenced in numerous treated animals, an autopsy study and the sampling of brain tissue with the meninges for histopathological and biochemical determinations were carried out.
- the animals received an anesthetic overdose were prefused with cold physiological saline solution by intracardiac route to drag the blood from the brain.
- the samples were subjected to cryo-cuts of 10 microns and colored with H / E, Congo Red or incubated with an antibody that specifically recognizes beta-amyloid.
- the morphometric processes were performed by capturing the microscopic image with a video camera attached to the microscope, being analyzed by the program
- Cerebral concentration of myo-inositol as an indicator of old age and deterioration of brain metabolism ( ⁇ mol / gram of tissue).
- treatment with each of the secretagogues significantly reduces the number of arteries, arterioles and capillaries positive to fibrillar amyloid (congo red) and granular deposits of osmiophilic material (coloration from Nissl). Consequently, the presence of subcortical microinfarms that constitute leukoencephalopathy, as well as the number of hemorrhagic foci also appear significantly diminished in each of the treatments with the compositions.
- the secretagogue peptides studied here show the ability to reduce or attenuate the neuro-toxicity that is caused by the high production of reactive oxygen species present in human disease, and also verified in animals that only receive saline solution. This effect extends the concept of general neuro-protection of these substances to contexts in which brain aging is mediated by vascular damage and excessive lipid peroxidation.
- Example 7 Effect of the peptides GHRP-6, GHRP-2, Hexarelina and / or Ghrelina in the elimination of the pathological deposits of physiological material of the skin.

- the treatments were performed once every 24 hours, for a period of 7 days.
- the substances were infiltrated at the edges of the implants, producing the local bioavailability of the active ingredients in the area, at doses from 1 milligram to 5 micrograms.
- the animals were sacrificed, and the implants removed for evaluation of the pharmacological response of each substance.
- the samples were fragmented for histological study and biochemical determinations of collagen, after being weighed.
- the fragments for histological study were fixed in 10% neutral formalin and those dedicated to biochemistry were stored at -70 degrees Celsius.
- the parameters studied were: a- Wet weight of each graft collected, b- Hydroxy-proline content in the tissue.
- each of the peptides at the doses tested exerts a potent anti-fibrotic effect in the established experimental system, characterized by being acute, rapidly reducing excess collagen material and extracellular matrix, reducing the number of inducing cells (mast cells) ) and effectors (fibroblasts and myofibroblasts). It is notorious that from the third infiltration with any of the peptides tested, the implants show a marked reduction in size and begin to turn pale and devitalized.
