Method for treating the form of alopecia commonly known as ''male pattern baldness'' which comprises regular topical application to the affected areas of the human scalp of a composition containing as at least one of its active ingredients of Formula I, wherein: either one of R1 and R2 is hydrogen and the other is selected from the class of C1-6 alkylcarbonyl, C1-6 alkoxycarbonyl, C1-6 alkylcarbonyloxy, C1-6 alkylhydroxymethyl, nitro, cyano, chloro, trifluoromethyl, C1-6 alkylsuphinyl, C1-6 alkylsulphonyl, C1-6 alkoxysulphinyl, C1-6 alkoxysulphonyl, C1-6 alkylcarbonylamino, C1-6 alkoxycarbonylamino, C1-6 alkylthiocarbonyl, C1-6 alkoxythiocarbonyl, C1-6 alkylthiocarbonyloxy, C1-6 alkoxythiolmethyl, formyl or aminosulphinyl, aminosulphonyl or aminocarbonyl, the amino moiety being optionally substituted by one or two C1-6 alkyl groups, or C1-6 alkylsulphinylamino, C1-6 alkylsulphonylamino, C1-6 alkoxysulphinylamino or C1-6 alkoxysulphonylamino or ethylenyl terminally substituted by C1-6 alkylcarbonyl, nitro or cyano, or -C(C1-6 alkyl)NOH or -C(C1-6 alkyl)NNH2, or one or R1 and R2 is nitro, cyano or C1-3 alkylcarbonyl and the other is methoxy or amino optionally substituted by one or two C1-6 alkyl or by C2-7 alkanoyl; one of R3 and R4 is hydrogen or C1-4 alkyl and the other is C1-4 alkyl or R3 and R4 together are C2-5 polymethylene; either R5 is hydrogen, hydroxy, C1-6 alkoxy or C1-7 acyloxy and R6 is hydrogen or R5 and R6 together are a bond; R7 is hydrogen, C1-6 alkyl optionally substituted by hydroxy, C1-6 alkoxy, C1-6 alkoxycarbonyl or carboxy, C1-6 alkyl substituted by halogen, or C2-6 alkenyl; aryl or heteroaryl either being optionally substituted by one or more groups or atoms selected from the class of C1-6 alkoxy, hydroxy, halogen, trifluoromethyl, nitro, cyano, C1-12 carboxylic acyl, or amino or aminocarbonyl optionally substituted by one or two C1-6 alkyl groups; R8 is hydrogen or C1-6 alkyl; or R7 and R8 are joined together to form C3-5 polymethylene or -CH2-(CH2)n-Z-(CH2)m- where m and n are integers 0 to 2 such that m+n is 1 or 2 and Z is oxygen, sulphur or NR9 wherein R9 is hydrogen, C1-9 alkyl, C2-7 alkanoyl, phenyl C1-4 alkyl, naphthylcarbonyl, phenylcarbonyl or benzylcarbonyl optionally substituted in the phenyl or naphthyl ring by one or two C1-6 alkyl, C1-6 alkoxy or halogen; mono- or bi-cyclic heteroarylcarbonyl; X is oxygen or sulphur; and the R8NCXR7 moiety is trans to the R5 group when R5 is hydroxy, C1-6 alkoxy or C1-7 acyloxy; or a pharmaceutically acceptable salt or solvate thereof. |
