Abstract

Compositions and methods for inhibiting and/or sensitizing or re-sensitizing a parasite to an antiparasitic drug are provided. The compositions can comprise a an arylphenoxypropionate derivative, an aryloxyphenoxyacetate derivative, an aryloxyphenylacetate derivative, one or more substituted quinols, or a pharmaceutically acceptable salt, hydrate, or prodrug thereof, or a combination thereof in an amount and formulation sufficient to sensitize the parasite to the drug, treating infection of a patient by a parasite with a drug, or to prevent symptomatic infection of a patient by a parasite with a drug.

First claim

The invention claimed is:

1. A method of sensitizing a parasite to a drug comprising administering an arylphenoxypropionate derivative, an aryloxyphenoxyacetate derivative, an aryloxyphenylacetate derivative, one or more substituted quinols, or a pharmaceutically acceptable salt, hydrate, or prodrug thereof, or a combination thereof to the parasite in an amount and for a time sufficient to sensitize the parasite to the drug,
wherein the parasite is a species of the genus Plasmodium , a species of the genus Ascaris , a species of the genus Enterobius , a species of the genus Trichinella , a species of the genus Haemonchus , a species of the genus Aphelenchoides , a species of the genus Ditvlenchus , a species of the genus Globodera , a species of the genus Heterodera , a species of the genus Longidorus , a species of the genus Meloidogyne , a species of the genus Nacobbus , a species of the genus Pratvlenchus , a species of the genus Trichodorus , a species of the genus Xiphinema , a species of the genus Bursaphelenchus , a species of the genus Fasciola , a species of the genus Coccidoides , or a species of the genus Onchocerca , or the parasite is selected from the group consisting of Pedicululs humanus, Phthiriasis pubis, Sarcoptes scabiei, Schistosoma mansoni, Schistosoma japonicum, Schistosoma haemotobium, Trichobilharzia regenti, Clonorchis simensis, Fasciola hepatica, Fasciola gigantica, Opisthorchis viverrinil, Paragonimus westermani, Paragonimus kellicotti, Fasciolopsis buski, Metagonimus vokagawai, Heterophyes heterophyes, Echinococcus granulosus, Echinococcus multilocularis, Taenia saginata, Taenia solium, Taenia asiatica, Hvmenolpeis nana, Hvmenolpeis diminuta, Diphvllobotrium latum, Diphvllobotrium mansonoides, Spirometra erinaceieuropaei, Dracunculus medinensis, Onchocerca volvulus, Lo vaginalis a loa, Mansonella perstans, Mansonella ozzardi, Mansonella streptocera, Wucheria bancrofti, Brugia malavi, Brugia timori, Gnathostoma spinigerum, Gnathostoma hispidium, Ancylostoma duodenale, Ancylostoma brazilienes, Necator americanus, Angiostrongylus cantonensis, Ascaris lumbricoides, Toxocara canis, Toxocara cati, Strongyloides stercoralis, Enterobius vermicularis, Trichinella spiralis, Trichuris trichiura, Cryptosporidium hominis, Cryptosporidium parvum, Isosporiasis belli, Cyclospora cavetanesis, Balantidium coli, Entamoeba histolvtica, dispar, Giardia lamblia, Trichmonas vaginalis, Dientamoeba fragilis, Blastocystis hominis, Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, Plasmodium malariea, Babesia divergens, Babesia microfti, Trypanosoma brucei, Trypanosoma cruzi, Leishomania mexicana, Leishomania aethiopica, Leishomania tropic, Leishomania braziliensis, Leishomania donovani , and Leishomania infantum, Eimeria vermiformis, Eimeria brunett, Eimeria praecox, Eimeria maxima, Eimeria mitis, Eimeria necatrix and Eimeria tenella.

2. The method of claim 1 , further comprising administering an arylphenoxypropionate derivative, an aryloxyphenoxyacetate derivative, an aryloxyphenylacetate derivative, one or more substituted quinols, or a pharmaceutically acceptable salt, hydrate, or prodrug thereof, or a combination thereof to the parasite before administering the drug to which the parasite is sensitized.

3. The method of claim 1 , further comprising administering an arylphenoxypropionate derivative, an aryloxyphenoxyacetate derivative, an aryloxyphenylacetate derivative, one or more substituted quinols, or a pharmaceutically acceptable salt, hydrate, or prodrug thereof, or a combination thereof to the parasite concurrently with the drug to which the parasite is sensitized.

4. The method of claim 1 , further comprising administering an arylphenoxypropionate derivative, an aryloxyphenoxyacetate derivative, an aryloxyphenylacetate derivative, one or more substituted quinols, or a pharmaceutically acceptable salt, hydrate, or prodrug thereof, or a combination thereof to the parasite after administering the drug to which the parasite is sensitized.

5. The method of claim 1 , further comprising administering an arylphenoxypropionate derivative, an aryloxyphenoxyacetate derivative, an aryloxyphenylacetate derivative, one or more substituted quinols, or a pharmaceutically acceptable salt, hydrate, or prodrug thereof, or a combination thereof to the parasite a second or greater time.

6. The method of claim 1 , wherein administering an arylphenoxypropionate derivative, an aryloxyphenoxyacetate derivative, an aryloxyphenylacetate derivative, one or more substituted quinols, or a pharmaceutically acceptable salt, hydrate, or prodrug thereof, or a combination thereof to the parasite in an amount and for a time sufficient to sensitize the parasite to the drug comprises rendering the parasite susceptible to the drug at a lower dose than in the absence of an arylphenoxypropionate derivative, an aryloxyphenoxyacetate derivative, an aryloxyphenylacetate derivative, one or more substituted quinols, or a pharmaceutically acceptable salt, hydrate, or prodrug thereof, or a combination thereof.

7. The method of claim 1 , wherein administering an arylphenoxypropionate derivative, an aryloxyphenoxyacetate derivative, an aryloxyphenylacetate derivative, one or more substituted quinols, or a pharmaceutically acceptable salt, hydrate, or prodrug thereof, or a combination thereof to the parasite in an amount and for a time sufficient to sensitize the parasite to the drug comprises rendering the parasite susceptible to a drug that the parasite would not be susceptible to in the absence of an arylphenoxypropionate derivative, an aryloxyphenoxyacetate derivative, an aryloxyphenylacetate derivative, one or more substituted quinols, or a pharmaceutically acceptable salt, hydrate, or prodrug thereof, or a combination thereof.

8. The method of claim 1 , wherein the drug comprises an antiparasitic drug and wherein administering arylphenoxypropionate derivative, an aryloxyphenoxyacetate derivative, an aryloxyphenylacetate derivative, one or more substituted quinols, or a pharmaceutically acceptable salt, hydrate, or prodrug thereof, or a combination thereof to the parasite in an amount and for a time sufficient to sensitize the parasite to the drug comprises rendering the parasite susceptible to death or a decrease in growth due to the antiparasitic drug.
