prodrug thereof, wherein A is a psychotropic derivative; L is a linking group comprising two carbon atoms; and B is an
alkyl, alkenyl, alkynyl or aralkyl comprising at least one
substituent of the formula Q, wherein: the
alkyl, alkenyl, alkynyl or aralkyl is optionally substituted with one or more halogean halogens, hydroxyl, cyano, nitro, amino or
thiol; and Q is OR6, OC(O)R6, C(O)R6, C(S)R6, CO2R6, C(O)SR6, C(O)NR6R7, C(S)NR6R7, NR6R7, NR6C(O)R7, NR6C(S)R7, NR6C(O)NR7R8, NR6C(S)NR7R8, NR6SO2R7, NR6SO2NR7R8, SR6, SC(O)R6, SC(O)NR6R7, S(O)R6, SO2R6, SO2NR6R7, or NR6SO2NR7R8.
