                                      APPENDIX                                      

              36.  A method for treating alopecia or promoting hair                 
         growth in an animal in need thereof, which comprises                       
         administering to said animal an effective amount of a                      
         heterocyclic nitrogen-containing compound which has an N-linked            
         sulfone substituent attached to the heterocyclic ring and has a            
         thioester substituent attached to the heterocyclic ring.                   

              40.  The method of claim 36, wherein the compound is of               
         formula I                                                                  







                                                                                   
         or a pharmaceutically acceptable salt, ester, or solvate                   
         thereof, wherein:                                                          
              A and B, taken together with the nitrogen and carbon atoms            
         to which they are respectively attached, form a 5-7 membered               
         saturated or unsaturated heterocyclic ring comprising one or               
         more O, S, SO, SO2, N, or NR2 heteroatom(s);                               
              X is either O or S;                                                   
              Y is a direct bond, C1-C6 straight or branched chain alkyl,           
         or C2-C6 straight or branched chain alkenyl,                               
              wherein any carbon atom of said alkyl or alkenyl is                   
              optionally substituted in one or more position(s) with                
              amino, halo, haloalkyl, thiocarbonyl, ester, thioester,               
                                        -1-
