| | HALOPROGIN Usage And Synthesis |
| Originator | Halotex,Westwood,US,1972 | | Uses | Haloprogin is a topical antifungal agent used in the treatment of dermatophytic and monilial infections. | | Uses | Antibacterial. | | Definition | ChEBI: Haloprogin is an aromatic ether. | | Indications | Haloprogin is used as an external drug for moderate dermatophyte infections (shingles),
and it is effective for superficial candida infections. Synonyms of this drug are halotex,
mycilan, micanden, and others. | | Manufacturing Process | 4.7 grams of 2,4,5-trichlorophenyl propargyl ether (MP 64° to 65°C) are
added to an aqueous solution of cupro-ammonium complex salt which has been prepared by warming a mixture of 4.0 grams of cuprous chloride, 11.0
grams of ammonium carbonate and 20 cc of water to 50°C. The resulting
admixture is shaken vigorously. The cuprous acetylide deposited is filtered,
washed with water and suspended in 100 cc of water, and the suspension is
mixed under agitation with a solution of 5.0 grams of iodine and 5.0 grams of
potassium iodide in 15 cc of water. The mixture is stirred for a period of 1
hour. The precipitate is filtered, washed with water and extracted with ether.
After the drying of the ethereal extract, the solvent is distilled off.
Recrystallization of the residue from n-hexane gives about 5.6 grams of 2,4,5-
trichlorophenyi iodopropargyl ether, MP 114° to 115°C. | | Brand name | Halotex (Westwood-Squibb). | | Therapeutic Function | Antibacterial | | General Description | 3-Iodo-2-propynyl-2,4,5-trichlorophenyl ether (Halotex)crystallizes as white to pale yellow forms that are sparinglysoluble in water and very soluble in ethanol. It is an etherealderivative of a phenol. Haloprogin is used as a 1% cream forthe treatment of superficial tinea infections.
Formulations of haloprogin should be protected fromlight because the compound is photosensitive. Haloprogin isavailable as a solution and a cream, both in a 1% concentration.Haloprogin is probably not the first topical agent thatshould be recommended. Although the cure rates for topicalfungal infections are relatively high, they come at a highprice. The lesion typically worsens before it improves.Inflammation and painful irritation are common. | | Synthesis | Haloprogin, 3-iodo-2-propinyl-2,4,5-trichlorophenyl ether (35.4.11), is synthesized by an iodide substitution using a mixture of iodine and potassium iodide and a
cupric derivative of 2,4,5-trichlorophenylpropargyl ether (35.4.10), which is synthesized
by a standard method from propargyl bromide and 2,4,5-trichlorophenol in the presence of
sodium hydroxide.
