Patent ID: 7056935

Claim:
A method for stimulating neurite outgrowth by a nerve cell, comprising: administering to said nerve cell an effective amount of compound having an affinity for FKBP-type immunophilins according to formula I or a pharmaceutically acceptable salt thereof, wherein Y is CH 2 , O, NH, or N—(C1–C4 alkyl); wherein Z and R 2 are independently Ar, (C5–C7)-cycloalkyl substituted (C1–C6)-straight or branched alkyl or alkenyl, (C5–C7)-cycloalkenyl substituted (C1–C6)-straight or branched alkyl or alkenyl, or Ar substituted (C1–C6)-straight or branched alkyl or alkenyl, wherein in each case, one or two carbon atoms of the straight or branched alkyl or alkenyl groups may be substituted with 1–2 heteroatoms selected from the group consisting of oxygen, sulfur, SO and SO 2 in chemically reasonable substitution patterns, or wherein Q is hydrogen, (C1–C6)-straight or branched alkyl or (C1–C6)-straight or branched alkenyl; wherein T is Ar or substituted 5–7 membered cycloalkyl with substituents at positions 3 and 4 which are independently selected from the group consisting of hydrogen, hydroxyl, O—(C1–C4)-alkyl or O—(C1–C4)-alkenyl and carbonyl; wherein Ar is selected from the group consisting of monocyclic and bicyclic heterocyclic aromatic ring systems with individual ring sizes being 5 or 6 which may contain in either or both rings a total of 1–4 hetero atoms independently selected from oxygen, nitrogen and sulfur; wherein Ar may contain one to three substituents which are independently selected from the group consisting of hydrogen, halo, hydroxyl, hydroxymethyl, nitro, CF 3 , trifluoromethoxy, (C1–C6)-straight or branched alkyl or (C1–C6)-straight or branched alkenyl, O-(C1–C4)-straight or branched alkyl or O—(C1–C4)-straight or branched alkenyl, O-benzyl, O-phenyl, amino, 1,2-methylenedioxy, carbonyl and phenyl; wherein R 1 is either hydrogen or U; X is either oxygen or CH—U, provided that if R 1 is hydrogen, then X is CH—U, or if X is oxygen then R 1 is U; wherein U is hydrogen, O—(C1–C4)-straight or branched alkyl or O—(C1–C4)-straight or branched alkenyl, (C1-C6)-straight or branched alkyl or (C1-C6)-straight or branched alkenyl, (C5–C7)-cycloalkyl, (C5–C7)-cycloalkenyl substituted with (C1–C4)-straight or branched alkyl or (C1–C4)-straight or branched alkenyl, [(C1–C4)-alkyl or (C1–C4)-alkenyl]-Ar or Ar (Ar as described above); wherein J is hydrogen or C1 or C2 alkyl or benzyl; K is (C1–C4)-straight or branched alkyl, benzyl or cyclohexylethyl; or wherein J and K may be taken together to form a 5 membered heterocyclic ring which may contain an oxygen (O), sulfur (S), SO or SO 2 substituted therein; and wherein n is 0–3.
