Vitamin D, Country Life


Cholecalciferol and ergocalciferol are used for the control of rats and mice.


Vitamin D3 analogue.


carnitine replenisher in peripheral arterial disease


The vitamin that mediates intestinal calcium absorbtion, bone calcium metabolism and probably, muscle activity. Occurs in and is isolated from fish liver oils. Vitamin D acts through a receptor that i s a member of the ligand-dependent transcription factor superfamily. Modulates the proliferation and differentiation of both normal and cancer cells. Has antiproliferative and antimetastatic effects o n breast, colon, and prostate cancer cells. Activated vitamin D receptors in intestine and bone maintain calcium absorbance and homeostasis.


selective phosphodiesterase-4 inhibitor (PDE-4 inhibitor) under investigation for treating respiratory diseases involving chronic inflammation such as asthma or COPD (smoker’s lung)


A free vitamin D 3, isolated in crystalline state from the 3,5-dinitrobenzoate, produced by irradiation, and equivalent in activity to vitamin D3 of tunaliver oil.


Vitamin D is the collective term for a group of compounds formed by the action of ultraviolet irradiation on sterols. Cholecalciferol (vitamin D3) and calciferol (vitamin D2) are formed by irradiation of the provitamins 7- dehydrocholesterol and ergosterol, respectively. The conversion to vitamin D3 occurs in the skin. The liver is the principal storage site for vitamin D, and it is here that the vitamin is hydroxylated to form 25-hydroxyvitamin D. Additional hydroxylation to form 1,25-dihydroxyvitamin D occurs in the kidney in response to the need for calcium and phosphate


Vitamin D3, through its active metabolite, 1,25- (OH)2D3, also plays an important role in maintaining calcium homeostasis by enhancing intestinal calcium absorption, PTH-induced mobilization of calcium from bone, and calcium reabsorption in the kidney.

Manufacturing Process

5 g of 7-dehydrocholesteryl acetate (prepared by W.R. Ness, R. S. Kostic and Mosetting, J. Am. Chem. Soc. 78, 436, 1956) were dissolved in 500 ml of nhexane. This solution was irradiated with ultraviolet ray by recyclicly passing it through a quartz apparatus surrounding 450 w high pressure mercury vapor lamps for 80 minutes. After irradiation and then the distillating off of nhexane the solution was added with 50 ml of ethanol and the ethanolic solution was left to stand overnight at the temperature of -20°C. The formed crystals were filtered off from ethanolic solution and filtrate was heated at the temperature 78°C for 4 hours. After cooling of filtrate, the cooled filtrate was added with 4 ml of ethanolic solution containing 0.7 g of potassium hydroxide to effect a reaction at the temperature of 20°C and under nitrogen for 60 minutes. The reaction product was added with 0.7 ml glacial acetic acid and then ethanol was distilled off under reduced pressure from the reaction product. The obtained residue was extracted with 50 ml of n-hexane and extract was washed with water and n-hexane was distilled off from extract to obtain 2.5 g of yellow oily matter containing vitamin D3. The content of vitamin D3 in yellow oily matter was 40.2% by weight.

Therapeutic Function

Vitamin, Antirachitic


The primary supply of vitamin D3 in humans is not obtained from the diet but rather is derived from the ultraviolet photoconversion of 7-dehydrocholesterol to vitamin D3 in skin. Thus, vitamin D3 synthesis varies with the seasons. D3 is a prohormone and requires further metabolic conversion to exert biological activity in its target organs. The liver and the kidney are the major sites of metabolic activation of this endogenous sterol hormone. The initial transformation of D3 occurs in the liver and is catalyzed by the enzyme 25-OH-D3-hydroxylase to form 25-(OH)D3; this is the primary circulating form of D3. Circulating 25-(OH)D3 is then converted by the kidney to the most active form of D3, 1,25-(OH)2D3, by the 1-(OH)-D3-hydroxylase enzyme. Blood concentrations of 1,25-(OH)2D3 are approximately one fivehundredth of those of 25-(OH)D3. 1, 25-(OH)2D3 is converted to the metabolite 24R,25-(OH)2D3, which is capable of suppressing parathyroid secretion.
In addition to the endogenous metabolites, some exogenous sterols possess biological activity similar to that of D3. Ergocalciferol (vitamin D2) is derived from the plant sterol ergosterol and may act as a substrate for both the 25-hydroxylase and the 1-hydroxylase enzyme systems of the liver and kidney to form 25-(OH)D2 and 1,25-(OH)2 D2, respectively. Ergocalciferol (vitamin D2) is the form used in commercial vitamins and supplemented dairy products. Dihydrotachysterol, another sterol that is used as a therapeutic agent, also functions as a substrate for the hydroxylase enzymes in the liver and kidney.

Landwirtschaftliche Anwendung

Rodenticide: Used in bait for vermin control. Vitamin D is a steroid hormone that has an important role in regulating body levels of calcium and phosphorus, and in mineralization of bone. Not approved for use in EU countries. Registered for use in the U.S. and other countries.



Biochem/physiol Actions

Vitamin D acts through a receptor that is a member of the ligand-dependent transcription factor superfamily. Modulates the proliferation and differentiation of both normal and cancer cells. Has antiproliferative and antimetastatic effects on breast, colon, and prostate cancer cells. Activated vitamin D receptors in intestine and bone maintain calcium absorbance and homeostasis.

Mechanism of action

1, 25-(OH)2D3 exerts its influence within target tissues through high-affinity sterol-specific intracellular receptor proteins.The D3 receptor, similar to steroid receptor systems, translocates the hormone from the cell cytoplasm to the nucleus, where biological response is initiated via transcription and translation.

Clinical Use

The principal disorder associated with inadequate vitamin D intake is rickets. The low blood calcium and phosphate levels that occur during vitamin D deficiency stimulate parathyroid hormone secretion to restore calcium levels. In children, this deficiency leads to the formation of soft bones that become deformed easily; in adults, osteomalacia results from the removal of calcium from the bone.Vitamin D deficiency may occur in patients with metabolic disorders, such as hypoparathyroidism and renal osteodystrophy. The requirement for vitamin D is slightly higher in members of darker-pigmented races, since melanin interferes with the irradiation that produces vitamin D3 in the skin. People with limited exposure to the sun may need to supplement vitamin D intake.


The hypercalcemia resulting from hypervitaminosis D is responsible for toxic symptoms such as muscle weakness, bone pain, anorexia, ectopic calcification, hypertension, and cardiac arrhythmias. Toxicity in infants can result in mental and physical retardation, renal failure, and death.


Poison by ingestion. An experimental teratogen. When heated to decomposition it emits acrid smoke and irritating fumes.

Cholecalciferol (vitamin D3) is the mammalian form of vitamin D. It is normally produced in the skin by the action of UV light on its precursor, 7- dehydrocholesterol. Essential amounts of the vitamin are obtained thus or from dietary sources such as fish oils. The active form of the vitamin is 1,25-dihydroxy-cholecalciferol. Its formation occurs in two stages: 25- hydroxylation in the liver, followed by 1-hydroxylation in the kidney (see Engstrom and Koszewski, 1989 and references cited therein).

läuterung methode

It is converted into its 3,5-dinitrobenzoyl ester and crystallised repeatedly from acetone. The ester is then saponified and the free vitamin is isolated. [Laughland & Phillips Anal Chem 28 817 1956, Beilstein 6 III 2811, 6 IV 4149.]


It is unstable in light and air and in acidic media. It is inactivated within a few days under normal exposure conditions. This is due to oxidation and fragmentation of the triene functionality.

Toxicity evaluation

Another steroidal rodenticide is cholecalciferol, which is in fact the naturally occurring vitamin D3. This compound is an essential factor for vertebrates but in large doses causes hypercalcemia, resulting in calcification and degeneration of various soft tissues, ultimately leading to death. In baits, cholecalciferol may be combined with other, usually anticoagulant, rodenticides. The main natural source of cholecalciferol is fish liver oil, but it is manufactured from ergosterol.


Sensitive to air, light, and moisture. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.

Waste disposal

Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material’s impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
