Riboflavin 5′-monophosphate sodium salt hydrate synthetic

Химические свойства

Riboflavin 5'-Monophosphate Sodium Salt is a yellow toorange-yellow, crystalline hygroscopic powder. It is odorless, and has a slightly bitter taste.

It is soluble in water, and practically insoluble in ethanol(95), in chloroform and in diethyl ether.
It is decomposed on exposure to light.

Использование

One of the bioactive forms of Riboflavin. Nutritional factor found in milk, eggs, malted barley, liver, kidney, heart, leafy vegetables. Richest natural source is yeast. Minute amounts present in all plant and animal cells. Vitamin (enzyme cofactor).

прикладной

Riboflavin 5'-Monophosphate Sodium Salt is a coenzyme that is tightly bound to enzymes catalyzing substrate oxidations and reductions, enable an enormous range of chemical transformations in biosynthetic pathways. Riboflavin 5'-Monophosphate Sodium Salt can be used as:
(1) A stable isotope internal standard for the interpretation of data in specific biological samples.
(2) An effective NAD+ reducing agent.
(3) To study progressive keratitis, corneal ectasia and irregular astigmatism.

Биологические функции

Riboflavin 5'-Phosphate Sodium is the phosphate sodium salt form of riboflavin, a water-soluble and essential micronutrient that is the principal growth-promoting factor in naturally occurring vitamin B complexes. Riboflavin phosphate sodium is converted to 2 coenzymes, flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), which are necessary for energy production by aiding in the metabolism of fats, carbohydrates and proteins and are required for red blood cell formation and respiration, antibody production and for regulating human growth and reproduction. Riboflavin phosphate sodium is essential for healthy skin, nails and hair growth.

Общее описание

Riboflavin 5′-monophosphate is also known as flavin mononucleotide (FMN). FMN is a water-soluble micronutrient. It is enzymatically produced from riboflavin (RF). Riboflavin 5′-monophosphate is one of the constituent of enzyme cofactor flavin-adenine dinucleotide.

IC 50

Cryptosporidium hominis TS-DHFR: IC50 = 55 μM; Dihydrofolate reductase: IC50 = 325 μM (human); Thymidylate synthase: IC50 >500 μM (human); Dihydrofolate reductase: IC50 >500 μM (Toxoplasma gondii)

Методы очистки

Purify FMN by paper chromatography using tert-butanol/water, cutting out the main spot and eluting it with water. It can also be purified by adsorption onto an apo-flavodoxin column, followed by elution and freeze drying. It crystallises from aqueous acidic solution.
