1 : A psilocin salt, ester or conjugate of Formula A
wherein s/e/c represents a salt, ester or conjugate, prepared from a mixture of psilocin and 1-hydroxy-2-naphthoic acid, 2-hydroxy-3-naphthoic acid, galactaric acid (mucic acid), glutamic acid, mandelic acid, naphthalene-2-sulfonic acid, camphorsulfonic acid, pantothenic acid, isethionic acid, chlorosulfonic acid, sulfur trioxide pyridine complex, sulfur trioxide N, N-dimethylformamide complex, sulfur trioxide triethylamine complex or sulfur trioxide trimethylamine complex.
2 : The psilocin conjugate of claim 1 prepared from a mixture of psilocin and galactaric acid (mucic acid).
3 : The psilocin ester of claim 1 depicted in Formula A1
prepared from a mixture of psilocin and sulfur trioxide pyridine complex.
4 : A pharmaceutical composition comprising the psilocin salt, ester or conjugate of claim 1 and one or more pharmaceutically acceptable excipients.
5 : A method for producing the psilocin salt, ester or conjugates of claim 1 comprising mixing psilocin with 1-hydroxy-2-naphthoic acid, 2-hydroxy-3-naphthoic acid, galactaric acid (mucic acid), glutamic acid, mandelic acid, naphthalene-2-sulfonic acid, camphorsulfonic acid, pantothenic acid, isethionic acid, chlorosulfonic acid, sulfur trioxide pyridine complex, sulfur trioxide N, N-dimethylformamide complex, sulfur trioxide triethylamine complex or sulfur trioxide trimethylamine complex.
