Eflornithine hydrochloride Chemical Properties,Usage,Production
Uses
Antineoplastic; antiprotozoal.
Uses
DL-alpha-Difluoromethylornithine Hydrochloride is an irreversible inhibitor of ornithine decarboxylase.
Indications
Vaniqa (eflornithine hydrochloride 13.9%) cream is a unique topical cream that slows anagen hair growth by irreversibly blocking the enzyme ornithine decarboxylase. This enzyme produces polyamines in the hair matrix that are partially responsible for the growth of the anagen hair. The cream was tested only on the upper lip and chin region. The onset of action is usually within 8 weeks of starting the b.i.d. treatment, and the hair growth will return to baseline within 8 weeks of discontinuing the drug. Patients need to be reminded that this product does not remove hair but slows its growth in between whatever they use for hair removal.
brand name
Ornidyl (Sanofi Aventis); Vaniqa (Skinmedica).
Synthesis
15THF was chilled to -80C and 2.82L of diisopropylamine was added under nitrogen protection, followed by 12L of a 15% butyl lithium hexane solution, added at a rate to maintain the temperature of the reaction solution at -75 to -80C. Then N,N'-diphenylmethylene ornithine methyl ester (I) dissolved in a solution of 15L THF was added. After addition, the reaction was slowly raised to 35 to 40C and nitrogen was replaced with a monochlorodifluoromethane bubble. 20 L of saturated sodium chloride solution and 75 L of isopropyl ether were added, the organic layer was separated and the aqueous layer was extracted. The extract and the organic layer were combined, washed with saturated sodium chloride solution and concentrated until an oily substance was left, which was compound (II). The oily material and 30Llmol/L hydrochloric acid were reacted at room temperature for 3h for hydrolysis. At the end of the reaction, it was extracted with chloroform and the extract was discarded. The extracted aqueous layer was diluted with 6L of water, adjusted to Ph 3.3, heated, filtered, washed and recrystallized to obtain eflornithine.
in vivo
Eflornithine is the only new molecule registered for the treatment of human African trypanosomiasis over the last 50 years. It is the drug used mainly as a back-up for melarsoprol refractory Trypanosoma brucei gambiense cases[1]. In subjects with excessive, unwanted facial hair, eflornithine 15% cream is superior to placebo in reducing hair growth. After 24 weeks' treatment, 58% of eflornithine and 34% of placebo subjects have at least some improvement in facial hirsutism[2]. The hair growth inhibitory activity of eflornithine is significantly enhanced when the eflornithine cream is applied onto a mouse skin area pretreated with microneedles[3]. Treatment of coarctation hypertensive rats with eflornithine results in a normalization of the contractile intensity to KCI and norepinephrine and relaxations to acetylcholine by 14 days of hypertension[4].
