Compounds for the treatment of cancers associated with human papillomavirus

Abstract

The present invention relates to the pyrrolidine substituted with flavone derivatives, represented by the compounds of Formula (I) or a pharmaceutically acceptable salt, a solvate, a stereoisomer or a diastereoisomer thereof for use in the treatment of cancers associated with human papillomavirus. The present invention also relates to the pharmaceutical compositions containing the compounds of Formula (I) for the treatment of cancers associated with human papillomavirus.

1 . A method for the treatment of human papillomavirus (HPV) associated cancer comprising administering to the subject in need thereof a therapeutically effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt, a solvate, stereoisomer or a diastereoisomer thereof; 
       
         
           
           
               
               
           
         
         wherein Ar is a phenyl group, which is unsubstituted or substituted by 1, 2, or 3 identical or different substituents selected from: halogen; nitro, cyano, C 1 -C 4 -alkyl, trifluoromethyl, hydroxyl and C 1 -C 4 -alkoxy. 
       
     
     
         2 . The method according to  claim 1  wherein, in the compound of Formula (I) Ar is a phenyl group substituted by 1, 2 or 3 identical or different substituents selected from chlorine, bromine, fluorine, iodine, C 1 -C 4 -alkyl and trifluoromethyl. 
     
     
         3 . The method according to  claim 1  wherein, in the compound of Formula (I) Ar is a phenyl group substituted by chlorine. 
     
     
         4 . The method according to  claim 1  wherein, in the compound of Formula (I) Ar is a phenyl group substituted by chlorine and trifluoromethyl. 
     
     
         5 . The method according to  claim 1 , wherein the compound of Formula (I) is a (+)-trans isomer represented by Formula (IA), or a pharmaceutically acceptable salt or a solvate thereof; 
       
         
           
           
               
               
           
         
         wherein Ar is a phenyl group, which is unsubstituted or substituted by 1, 2, or 3 identical or different substituents selected from halogen, nitro, cyano, C 1 -C 4 -alkyl, trifluoromethyl, hydroxyl or C 1 -C 4 -alkoxy. 
       
     
     
         6 . The method according to  claim 5 , wherein the compound of Formula (IA) is (+)-trans-2-(2-Chlorophenyl)-5,7-dihydroxy-8-(2-hydroxymethyl-1-methylpyrrolidin-3-yl)-chromen-4-one hydrochloride (compound A). 
     
     
         7 . The method according to  claim 5 , wherein the compound of Formula (IA) is (+)-trans-2-(2-Chloro-4-trifluoromethylphenyl)-5,7-dihydroxy-8-(2-hydroxymethyl-1-methylpyrrolidin-3-yl)-chromen-4-one hydrochloride (compound B). 
     
     
         8 . The method according to  claim 1 , wherein the HPV associated cancer is selected from anal cancer, vulvar cancer, vaginal cancer, penile cancer, cervical cancer, oropharyngeal cancer, cancer of the oral cavity, lung cancer, non-melanoma skin cancer and cancer of the conjunctiva. 
     
     
         9 . The method according to  claim 8 , wherein the HPV associated cancer is cervical cancer. 
     
     
         10 . A method for the treatment of human papillomavirus (HPV) associated cancer comprising administering to the subject in need thereof a therapeutically effective amount of a pharmaceutical composition comprising a therapeutically effective amount of the compound of Formula (I) as defined in  claim 1 , or a pharmaceutically acceptable salt, a solvate, a stereoisomer or a diastereoisomer thereof and a pharmaceutically acceptable carrier. 
     
     
         11 . The method according to  claim 10 , wherein the pharmaceutical composition comprises at least one further pharmaceutically active compound, wherein the pharmaceutically active compound has anticancer activity.
