Definitions
- the present invention relates to the branch of animal and human health, and particularly to a product that exhibits potent anticoccidial activity, which has been evaluated with very satisfactory results in experimental and industrial exploitation animals that are used as a food source .
- Prior Art There have been reported, in scientific articles and patent information, in particular, nitrous compounds, which show action against coccidia. However, although the commercial offer of these products still exists in the markets, their consumption has been decreasing due to the same toxic properties related to the position of the nitro group in carbon 5 of the furian ring.
- Other products include furazolidone (FUROBAC) and nitrofurazone (Environmental Mutagenesis 5: 745-765 (1983), Com.Reg. 19.03.92 (L73), Com.Reg. 15.10.93 (L 264).
- the present invention is based on a single compound with a furnic base, 2- (2- nitrovinyl) -furan, which has a nitro group in its structure, but not in the 5 position of the ring, but attached to the exocyclic double bond. It has been corroborated by predictive and experimental methods that this variation in the position of the nitro group in this family favorably modifies both pharmacological and toxicological properties.
- the present invention also includes a new process for obtaining 2- (2-nitrovinyl) -furan, which comprises the following steps:
- the condenser of the reaction equipment is connected to absorption traps that contain water to be able to absorb nitrous gases, thus avoiding environmental contamination.
- reaction mixture is allowed to cool between -15 and 10 ° C and the crude thus obtained is separated by solid-liquid separation methods preferably by centrifugation or vacuum filtration.
- the crude product is purified by dissolving it preferably in 4 to 10 volumes of ethanol at a temperature between 40 and 65 ° C for a contact time between 10 and 30 minutes, with 5 to 25% activated carbon.
- the activated carbon is filtered and allowed to precipitate at a temperature between -15 and 10 ° C.
- the pure product thus obtained is filtered, dried in a vacuum oven for 1 to 3.5 hours at a temperature ranging between 20 and 50 ° C and it is stored at a temperature between 10 and 20 ° C.
- 2- (2-nitrovinyl) -furan obtained by the described process with a purity of at least 98%, as well as 2- (2-nitrovinyl) -furan with a purity of 99% or more.
- This procedure in addition to allowing the aforementioned compound to be obtained with high purity, is characterized in that the gaseous residuals generated in the process are absorbed in water to avoid environmental contamination.
- the pharmaceutical composition containing as active ingredient 2- (2-nitrovinyl) -furan which additionally can include at least one excipient, additive or adjuvant, as well as the use of 2- (2 -nitrovinyl) -furan as a medicine, and particularly useful in the treatment of coccidiosis.
- the concentration of 2- (2-nitrovinyl) -furan in the pharmaceutical composition for use in the treatment of coccidia in human and veterinary medicine ranges between 2 and 80 ppm.
- the Average Lethal Dose (LD50) orally of 2- (2-nitrovinyl) -furan using different solvents was 1, 02 g / kg of Body mass for adult Leghorn chickens and 171.91 mg / kg body mass for female and male Sprague Dawley rats.
- Table 1 shows the degrees of purity obtained in the synthesis of 2- (2- nitrovinyl) -furan carried out in 6-liter reactors, under the different conditions tested.
- 2- (2-Nitrovinyl) -furan in a formulation as described in Example 2 was applied in the drinking water twice a day (8 AM and 12 M) for 5 days, to 2000 replacements of Leghorn layers with 56 -84 days old, naturally infected with E. Tenella.
- Two ships of 2000 birds each were selected, which were highly infected by cecal coccidiosis, where an average of 119 deaths were occurring in 5 days per ship, diagnosed by the presence of bloody diarrhea, the observation of typical lesions in the intestinal blinds and abundant presence of the parasite's oocysts in the cecal content.
- An infected ship was left as an untreated control and another uninfected was selected for uninfected control, nor treated with the same age range.
