Definitions
- composition on the basis of Stachytarpheta sp., a process for obtaining the same and its use for treating vitiligo.
- This invention generally refers to the obtention of a compound and a standard pharmaceutical product from roots, stems, barks, and leaves of plants of the Stachytarpheta (Verbenaceae family) genus, in the form of extracts or enriched fractions, or pure isolated compounds or compounds obtained from synthesis or semi-synthesis, used alone (pure extract) or mixed with other natural or synthetic products, in different ratios, in order to integrate pharmaceutical compositions to be used by appropriate routes (topic or oral), particularly in the form of tablets, capsules, dyes, emulsions, W/O and O/W (creams and gels) , liposomes, microcapsules, nanoparticles, aerosols, ointments, and the like, as well as formulations for slow-release implants, used to treat vitiligo and manifestations thereof - loss of skin pigment.
- vitiligo was used for the first time by the Roman physician Celsus (50 a. C). It originates from the Latin word vitilus, which means white patch. The descriptions of such disease were recorded in the Ebers Papyrus (1500 b.C), and in the Malawi sacred book Anthe
- Vitiligo is a disease characterized in that the skin patches that may appear in several body parts, mainly arms, legs, mouth, and eyes. In all cases, the melanin is observed to disappear. The vitiligo occurs by the destruction of melanocytes, however the cause is not completely clear. There are four theories suggested for the development of vitiligo: autoimmune, self-destructive, neurogenic and mixed therapy.
- Vitiligo is considered an autoimmune disease, presented as a melanocyte-specific immunological and multifactorial disease of endogenous origin: genetics and melanocitary oxidation or of exogenous origin: rubbing, skin lesions (K ⁇ ebner Phenomenon) .
- keratinocytes in vitiligo are capable of recycling the 5, 6, 7, 8-tetrahydrobiopterin (6-BH 4 ), an adjuvant factor for the hydroxylation of L-phenylalanine into L-tyrosine. This may break the supply of L-thyroxine for the melanin production, increasing the catecholamine by the keratinocytes, resulting in the accumulation of toxic free radicals that may damage the melanocytes .
- the vitiligo may occur in eight forms:
- melagenine helps decreasing the patches in 75% of the patients.
- Diprosalic Diprosalic solution, less efficient than melagenine, is topically used on the patches.
- Use of sun protection factors used across all treatment variations . Sun burnt leads to a potential photocarcinogenesis and may broaden unpigmentation areas (Koebner Phenomenon) .
- topical corticosteroids Used for small vitiligo patches with response after weeks or months .
- One of the most powerful includes betamethasone and clobetasol propionate.
- the follow-up on a monthly or bimonthly basis guarantees the control of side effects, such as spider veins, acne and skin atrophy. Upon any sign of those effects, the intermittent use shall be avoided.
- the treatment outcomes must be observed within three months, taking into account that those are immunosupressor drugs.
- PUVA The most usual vitiligo treatment is the photochromotherapy associated to psoralen, usually 8 -methoxypsoralen (8- MOP) , and artificial exposure to a 315-400 nm fluorescent lamp for approximately 10 minutes.
- the pigmentation may occur gradually in a perifollicular manner (around the hair follicle) , although a few cases it acts over the whole area. If no response is achieved within three months, the treatment must be discontinued. In case of repigmentation responses, it may be applied for one to one and a half year, always with approximately 2 -month resting intervals, since these drugs are considered hepatotoxic, nephrotoxic and cause gastric and ocular disorders.
- the treatment shall be administered with 100 to 150 expositions. Only 30% of the patients who underwent the PUVA therapy achieved a good repigmentation, and among them, approximately 75% relapsed within 2 to 3 years .
- the document PI 0406343-0 relates to the use of aqueous, hydroalcoholic, alcoholic or organic solvents extracts from leaves and/or aerial parts of the Stachytarpheta polyura species, used to treat vitiligo.
- This species, Stachytarpheta polyura is rarely found in nature, and its diminutive size makes the production of the extract in industrial scale unfeasible, costly and unprofitable.
- the newly developed product may be synthesized, semi- synthesized or obtained from alcoholic, aqueous or hydroalcoholic or organic extracts from one or more parts of plants of one of the following species, or a mixture thereof: S. cayennensis, S. jamaicensis and S. eliotis.
- the species used in this invention are more easily found in nature than Stachytarpheta polyura, mentioned on the prior art, in larger quantities, as well as larger sizes, increasing the feasibility of the production in industrial scale.
- Such species popularly known as gervao, gerbao, overjao, cha-do-Brasil ("verbena/vervain”) , among other popular names, are used in the traditional medicine as cicatrizant, treatment for stomach problems and antifebrile.
- the new pharmaceutical invention uses pure extracts, synthetic or semi-synthetic compounds or isolates from those plants' extracts, whether alone or mixed with each other or yet associated to extracts, fixed oils, essential oils, fragrances, powders or excipients from other natural or synthetic sources .
- this invention is about a process to produce a pharmaceutical product from standardized extracts, fractions or isolate molecules from plants of the Stachytarpheta genus, S. cayennensis, S. jamaicensis and S. eliotis species of the Verbenaceae family, to be used as a medication to treat vitiligo.

- the biomass obtained through the process (a) is extracted by percolation, or maceration, or soxlhet, or using gases in supercritical state, or extraction using a base or acid medium or an organic solvent or extraction by steam distillation; considering that the organic solvents are, for example, halogenated compounds, alcohols, aldehyde, ketones, cycloalkanes or alkanes, phenolic compounds, benzenes and derivatives, among other, whether alone or their mixtures; and in the case of an acid/base extraction, the extraction may be performed with strong or weak acids, whether diluted or concentrated, alone or mixed, such as acetic acid, hydrochloric acid, formic acid; and the base used in the extraction process is formed by concentrated or diluted bases, whether alone or in mixtures, such as, for example, ammonium hydroxide (NH 4 OH) and sodium carbonate (Na 2 CO 3 ) ;
- NH 4 OH ammonium hydroxide
- Na 2 CO 3 sodium carbonate
- the extract obtained may be dried using spray-dryer, with inlet temperature of approximately 150-190 °C, and outlet temperature of approximately 60-90°C; or under reduced pressure, with temperature ranging between 25-75 0 C; or at room temperature.
- the process allows the production in industrial scale, since it reduces the process time, presents an appropriate yield and results in a pharmaceutical product.
- the medication, according to this invention contains around 0.001 to 99% of at least one of the compounds or their mixtures in free form or in salt form (such as chlorates, sulfates or borates) of chemical structure (I) , (II) , (III) , (IV) , (V) , (VI) and (VII) .
