Methods for treating hair loss using a composition including a compound having the following structureand pharmaceutically acceptable salts, hydrates, and biohydrolyzable amides, esters, and imides thereof are provided. R1 is -(CH2)n(CHNR7R8)mC(O)R9, wherein n is an integer from 1 to 3, and m is an integer from 0 to 1. R3 and R5each, independently, is chlorine, bromine, iodine and -CH3. R7 and R8 each, independently, is hydrogen or C1 to C4 alkyl. R9 is hydroxy, C1 to C4 alkoxy and -NR7R8. R31 is a hydrogen, chlorine, bromine, iodine, C1 to C4 alkyl, C4 to C6 cycloalklyl, C1 to C4 haloalkyl, C4 to C6 halocycloalkyl, or CH(R10)Ar. Ar is 5-hydroxypyrid-2-yl, 6-hydroxypyrid-3-yl, 6-hydroxypyridazin-3-yl, 6-methioxypyridazin-3-yl N-oxide or 6-hydroxypyridazin-3-yl N-oxide. R10 is hydrogen or C1 to C4 alkyl. R41 is hydroxy or C1 to C4 alkoxy. |
