Definitions
- the invention relates to a riboflavin derivative and a preparation method and application thereof.
- Riboflavin is a component of the flavin enzyme prosthetic group. It is involved in the complex oxidation process of the body and plays an important pharmacological role. In recent years, pharmacological studies have shown that in addition to treating traditional riboflavin deficiency diseases, riboflavin also has pharmacological effects in the treatment of coronary heart disease, hypertension complications, and burns. However, riboflavin is a water-soluble vitamin, which is easily eliminated from sweat and urine, has a short half-life, and has low bioavailability.
- riboflavin intake when riboflavin intake is insufficient or the demand is increased, it can easily cause cheilitis, cheilitis, glossitis, scrotal dermatitis, etc., which are collectively called oral genital syndrome, as well as various nucleus such as conjunctivitis and bulbitis that affect vision. Flavin deficiency. For a long time, in order to prevent riboflavin deficiency caused by various reasons, a lot of research has been carried out on riboflavin derivatives. It is hoped that a suitable riboflavin derivative can be found as a prodrug and slowly released in vivo.
- the riboflavin is in its original form and can be stored in the body for a long time after a single application to exert the effect of the drug.
- Japanese scholar Kimi 0 and Miyamoto et al Synthesized riboflavin tetrapalmitic acid, tetradecanoate, tetrabutyrate, tetraacetate, and tryptophan tetraester by using riboflavin and fatty acid acyl chloride or anhydride in pyridine.
- these esters cannot be hydrolyzed in saliva and small intestinal fluid. Further research on tetrapalmitate showed that it has no riboflavin biological activity.
- the object of the present invention is to provide a riboflavin derivative and a synthesis method thereof.
- the derivative introduces a long-acting group, which can increase the retention of riboflavin in the body, so that it can increase absorption, delay excretion, and improve biological Utilization, to achieve the purpose of long-term effect.
- the riboflavin derivatives provided by the present invention are riboflavin tetrastearate, tetrapalmitate, trilaurate, tetradecanoate, tetrabutyrate, tetraacetate, and tryptophan. Tetraesters, all riboflavin phosphates except riboflavin phosphate, or ester derivatives on the ribitol hydroxyl group of the thioriboflavin side chain.
- the riboflavin derivative is a mono-, di-, tri- or tetra-ester compound represented by formula (I), wherein R 2 , R 3 , and R 4 are different, the same, or exist independently.
- the above riboflavin derivatives can be prepared by conventional methods.
- riboflavin-5'-lauric acid monoester represented by the structural formula ( ⁇ ) (
- the riboflavin-5'-lauric acid monoester is prepared by adding lauroyl chloride dropwise to riboflavin or thioriboflavin suspended in a polar organic solvent.
- the polar organic solvent of the suspended riboflavin or thioriboflavin is preferably pyridine or dimethylformamide.
- a second object of the present invention is to provide a riboflavin long-acting preparation using the compound of the present invention as an active ingredient and a preparation method thereof.
- a riboflavin long-acting oil suspension preparation is basically composed of a compound of formula ( ⁇ ) and ethyl oleate.
- camellia oil is also added to the oil suspension preparation, and the weight (volume) ratio of each component is:
- the preferred ratio of the weight (volume) of each component of the oil suspension formulation is:
- the riboflavin long-acting oil suspension preparation of the present invention is prepared by pulverizing the raw materials by a conventional blending method.
- riboflavin derivatives of the present invention have obvious effects in preventing and treating riboflavin deficiency, and overcome the defects that the existing riboflavin is easily discharged from body fluids, has a short half-life, and has low bioavailability.
- the long-acting riboflavin-5'-laurate in the compounds of the present invention is the compound with the highest yield and the best effect.
- four major spectral analyses (including two Dimensional superconducting nuclear magnetic resonance analysis) proves that it is a novel structured, novel riboflavin derivative.
- a long-acting riboflavin sleeve suspension injection prepared by using the riboflavin-5'-laurate, a single intramuscular injection of 150mg / ml, the effect is up to three months, in order to prevent common riboflavin deficiency Disease provides an important medical treatment.
- FIG 1 shows the changes in animal food intake during the experiment.
- FIG. 2 shows the changes in animal weight during the experiment.
- Figure 3 shows the changes in BGRAC of animals during the experiment.
- Figure 4 shows the changes of riboflavin content in the plasma of the animals during the experiment.
- the mixed solvent mother liquor was dried under reduced pressure at 35 ° C to obtain a red solid.
- the solid was washed with diethyl ether, dichloromethane 100mlX5, methanol 50mlX5, dried and crushed, and placed in a phosphorus pentoxide dryer for 48h to obtain 2.60g of red solid. Ester crude.
- the riboflavin was suspended in isobutyric anhydride, and perchloric acid was added dropwise at room temperature. After the addition, the reaction was stirred for 7 hours. The reaction solution was transparent purple, precipitated with ether, crystals were precipitated, filtered, and then dissolved with 30 ml of n-butanol. After crystallization, n-butanol was washed with water several times, dried, and diethyl ether was added to precipitate the crystals, filtered, dried under vacuum, and filtered to obtain a crude product.
- the target compound was obtained by the same separation method as in Example 1.
- Example 5 Preparation of an oil suspension formulation using the compound of the present invention as an active ingredient Formula: 50 mg of the compound of formula ( ⁇ ) (50-150 mg is acceptable)
- the compound of formula (II) was pulverized to 2-10 ⁇ m with an air stream, mixed with ethyl oleate and camellia oil, filled into a 1 ml ampoule, and sterilized to obtain an oil suspension preparation.
- Rat tests were used to determine the effects of long-acting riboflavin monoesters on preventing riboflavin deficiency by measuring urine riboflavin excretion, whole blood glutathione reductase activity coefficient, and plasma riboflavin content. Experimental evaluation of the month.
- AIN-76 was adapted for one week, and was randomly divided into 6 groups according to weight, namely the normal control group, riboflavin deficiency group, riboflavin group, long-acting riboflavin monoester low, medium and high dose groups. Flavin's AIN-76 was served, and tap water was freely consumed, daily food intake was recorded, and body weight was measured every 6 days. At the beginning of the test, orbital blood of normal control animals was taken, anticoagulated, and whole blood glutathione reduction was measured. Enzyme activity coefficient (BGRAC).
