Ciclopirox Chemische Eigenschaften,Einsatz,Produktion Methoden

• Chemische Eigenschaften

  White or Light-Yellow Powder

• Originator

  Fungirox Esmalte, UCI-Farma

• Verwenden

  Broad spectrum antimycotic agent with some antibacterial activity.

• Verwenden

  Ciclopirox (Penlac) is a synthetic antifungal agent. Ciclopirox (Penlac) is used for topical dermatologic treatment of superficial mycoses. Ciclopirox (Penlac) is most useful against Tinea versicolor. [1] In a study conducted to further elucidate ciclopir

• Indications

  Ciclopirox penetrates rapidly into and through the skin and nail keratin. After dermal application ofa1% cream formulation, about 1.3 % of the dose is absorbed. Serum levels range around 10 μg/L after application of a dose of 37 mg of ciclopirox. After vaginal administration, 15 – 20 % of the dose is absorbed. Ciclopirox penetrates well into the skin and nail matrix. Absorbed ciclopirox is mainly eliminated by the kidneys; 1.1 – 1.7 % of the topical dose is eliminated in the urine within four days. Only a fraction thereof is unaltered ciclopirox. Approximately 96% of the absorbed drug is bound to human serum proteins.

• Definition

  ChEBI: A cyclic hydroxamic acid that is 1-hydroxypyridin-2(1H)-one in which the hydrogens at positions 4 and 6 are substituted by methyl and cyclohexyl groups, repectively. A broad spectrum antigfungal agent, it also exhibits antibacterial acti ity against many Gram-positive and Gram-negative bacteria, and has anti-inflammatory properties. It is used a a topical treatment of fungal skin and nail infections.

• Manufacturing Process

  A mixture of 5-oxo-3-methyl-5-cyclohexylpentene-2 acid 1-methyl ester and 5-oxo-3-methyl-5-cyclohexylpentene-3 acid 1-methyl ester was obtained by condensation of hexahydrobenzoyl chloride with β,β-dimethylacrylic acid methyl ester. 11.2 g of this mixture and a solution of 4.6 g of sodium acetate and 4 g of hydroxylamine hydrochloride were shaken for 20 hours at 25°C with a mixture of 8 ml of water and 15 ml methanol. Subsequently, a solution of 4 g of sodium hydroxide in 8 ml of water was then added, while cooling, shaken for 1 hour at room temperature. The mixture was extracted by means of benzene and the aqueous phase was acidified to reach a pH of 6. 3.5 g of 1-hydroxy-4-methyl-6-cyclohexyl-2-pyridone were obtained; melting point 144°C.
  For preparation of cyclopirox from 1-hydroxy-4-methyl-6-cyclohexyl-2- pyridone was added 2-aminoethanol (1:1).Merck Index, Monograph number: 2325, Twelfth edition, 1996, Editor: S.

• Therapeutic Function

  Antifungal

• Antimicrobial activity

  Ciclopirox has a broad in vitro antifungal activity spectrum, including dermatophytes, yeasts, and moulds. The most important fungi within the activity spectrum of ciclopirox. Ciclopirox is primarily fungistatic, but if the contact time is long enough and the concentration exceeds 20 μg/mL, it exerts a fungicidal effect on yeasts and dermatophytes. In vitro, the effect is limited to proliferating fungi and is greatly dependent on the nutrient medium.

• Mechanism of action

  Ciclopirox has a unique mechanism of action through chelation of polyvalent cations, such as Fe3+, which causes inhibition of a number of metal-dependent enzymes within the fungal cell.

• Mechanism of action

  Ciclopirox is a substituted pyridione derivative. Experiments show that the mechanism of action involves a disruption of transport mechanisms into the cell plasma, especially the uptake of leucine. Further, the uptake of other amino acids such as phenylalanine and lysine, as well as the uptake of potassium and phosphate ions is impaired. This all probably involves a change in membrane permeability, as reported for some other antimycotics, although ciclopirox does not show lytic activity. Consecutively, the substance significantly reduces fungal growth rates.

• Clinical Use

  Ciclopirox is a hydroxylated pyridinone that is employed for superficial dermatophytic infections, principally onychomycosis.

• Nebenwirkungen

  Topically applied, ciclopirox is well tolerated. The incidence of local irritations such as itching and burning sensations range between 1 and 4 % and are often due to the galenic formulation.
