1 . A compound of the following chemical formula:  
       
         
           
           
               
               
           
         
         where:  
         R 1  is 
 alkyl;  
 alkenyl;  
 alkynyl;  
 CN;  
 SR 5 ; or  
 CF 3 ;  
 
         R 2 =alkyl or CH(O);  
         R 5 =hydrogen, alkyl, alkenyl, alkynyl, aryl, or heterocyclyl;  
         or a pharmaceutically acceptable salt thereof, wherein the alkyl and alkenyl groups may be branched, straight, unsubstituted, and/or substituted and wherein the aryl, alkynyl, and heterocyclyl groups are substituted or unsubstituted.  
       
     
     
         2 . A compound of the following chemical formula:  
       
         
           
           
               
               
           
         
         where:  
         R 1 =alkyl or SR 5 ;  
         R 5 =hydrogen, alkyl, alkenyl, alkynyl, aryl, or heterocyclyl;  
         or a pharmaceutically acceptable salt thereof, wherein the alkyl and alkenyl groups may be branched, straight, unsubstituted, and/or substituted and wherein the aryl, alkynyl, and heterocyclyl groups are substituted or unsubstituted.  
       
     
     
         3 . A compound of the following chemical formula:  
       
         
           
           
               
               
           
         
         where:  
         R 1 =alkyl;  
         or a pharmaceutically acceptable salt thereof, wherein the alkyl group may be branched, straight, unsubstituted, and/or substituted.  
       
     
     
         4 . A compound of the following chemical formula:  
       
         
           
           
               
               
           
         
         where:  
         R 5 =alkyl;  
         or a pharmaceutically acceptable salt thereof, wherein the alkyl group may be branched, straight, unsubstituted, and/or substituted.
