Abstract
The present invention discloses a method for preparing iron porphyrin sodium salt from chlorophyll iron sodium salt. The method is characterized in that deferrization is carried out to chlorophyll iron sodium salt through diluted sulfuric acid; then, aromatizing reaction is carried out for removing isoamyl rings for forming 1, 3, 5, 8-tetramethyl-2-vinyl-4-ethyl-6, 7 sodium dipropionate porphyrin in a large pi bonding structure; protoporphyrin generates complexation with iron ions for generating iron porphyrin; than, water-soluble sodium salt is prepared. The present invention has the advantages of simple and reliable production technology, low cost and high yield and can be used for industrialization production with certain scales.
Description
Technical field
The present invention relates to a kind of preparation method of organic compound, relate in particular to a kind of preparation method of ferriporphyrin sodium salt.
Background technology
1996, we invented the method for producing iron porphyrin from chlorophyll, and 1998, we invented the production technique of metalloporphyrin again.In order to satisfy the needs of medicine industry, we have developed the industrialized preparing process of ferriporphyrin sodium salt again with great concentration.Ferriporphyrin sodium salt is the water-soluble sodium salt of iron porphyrin, it be generally acknowledge in the world prevent and treat the most effective medicine of hypoferric anemia, because of its iron-holder height (9.03%), and with its molecular form directly be absorbed by the body, the utilization ratio height, absorb fast, can reach the function of enriching blood fast, thereby be considered to substitute the update medicine that traditional in the market inorganic salts is mended chalybeate.In addition, also can be used for foodstuff additive, add the functional foodstuff of making the treatment hypoferric anemia in beverage, cake, candy, biscuit, the chocolate etc.
The ferriporphyrin sodium salt compound is not all seen the report that suitability for industrialized production is arranged at home and abroad, thereby does not have commodity yet, and some scholars, expert attempt to be unrealized with the synthetic method both at home and abroad, but because of processing condition require harshly, complicated, cost is too high and can not implement.Also attempt from the blood of animal, to extract, as ox blood, pig blood, sheep blood etc., but also preserve and be subjected to strict restriction because of the transportation of blood products, the extraction and separation process complexity, cost consumption is too big, thereby does not form scale production, and its purity also is restricted, over more than 100 year, domestic and international scientist's way that never achieves a solution.
Summary of the invention
Purpose of the present invention is exactly for a kind of preparation method with ferriporphyrin sodium salt of the hypoferric anemia of preventing and treating is provided, and this method technology is simple, cost is lower.
Purpose of the present invention can be achieved through the following technical solutions: a kind of preparation method of ferriporphyrin sodium salt, and the structural formula of this ferriporphyrin sodium salt is as follows:
It is characterized in that the preparation method of described ferriporphyrin sodium salt comprises following processing step: the first step with sodium-iron-chlorophyllin dilute sulphuric acid deferrization, generates CHLOROPHYLLINE; Second step, with the CHLOROPHYLLINE that obtains in the ethylene glycol solution of 20～50% (weight) potassium hydroxide, aromatization under reflux temperature, generate 1,3,5,8-tetramethyl--2-vinyl-4-ethyl-6,7-dipropionic acid porphyrin generates sodium salt with this porphyrin and sodium hydroxide effect again, and centrifugal spray drying makes protoporphyrin disodium salt; The 3rd step, the prophyll quinoline disodium salt that makes and ferrous ion compound 10～70 ℃ of following complexings 3～5 hours, are neutralized to PH=4 with protonic acid again and separate out crystallization, filter, washing, add sodium hydroxide and generate ferriporphyrin sodium salt solution, centrifugal spray drying makes the ferriporphyrin sodium salt product.
Described CHLOROPHYLLINE is reacted in the ethylene glycol solution of 30～40% (weight) potassium hydroxide, and the ratio of CHLOROPHYLLINE and this solution is 1: 4～6 (weight).
Described reflux temperature is 190～210 ℃, and the reaction times is 2～24 hours.
Described ferrous ion compound is selected from a kind of in ferrous sulfate, the iron protochloride.
Described protonic acid is selected from a kind of in sulfuric acid, the hydrochloric acid.
Advantage of the present invention is tangible: technology is simple, the yield height, and the chemical structure of purpose compound is consistent substantially with protoheme, and iron-holder height, ferro element account for 9% of ferriporphyrin sodium salt, exceed 6 times of pig blood products.The present invention is raw material with the sodium-iron-chlorophyllin, and the production technique Nonpoisonous, non-environmental-pollution produces, and quality product is safe and reliable.
Ferriporphyrin sodium salt shows that through the bioavailability evaluation it is a good benefit chalybeate of preventing and treating hypoferric anemia.Prove that through toxicity test to mice lavage, observe a week with the dosage of 10g/Kg, not seeing has the acute poisoning symptom and the phenomena of mortality, belong to nontoxic level.Simultaneously negative through its result of Salmonella reversion test, therefore, the method for the ferriporphyrin sodium salt of producing from sodium-iron-chlorophyllin for the suitability for industrialized production of the medicine of effectively preventing and treating hypoferric anemia, has been opened up an approach with very high realistic meaning and practical value.
