Abstract

1495197 Pyridoxin derivatives LAMBELETTI ESPANA SA 6 Nov 1975 [6 Nov 1974] 46094/75 Heading C2V Pyridoxin derivatives have the formula where Y is n is 2 or 3 and R<SP>1</SP> and R<SP>2</SP> are alkyl or cycloalkyl radicals or R<SP>1</SP> and R<SP>2</SP> together with the nitrogen atom form a heterocyclic ring. The derivatives may be in the form of non-toxic salts with organic and inorganic acids. The derivatives are obtained by reacting basic esters of p-aminobenzoic acid with pyridoxal by elimination of water. In examples pyridoxal hydrochloride is reacted with diethyl-amino-ethyl p-aminobenzoate, with di-n-butyl-amino-propyl-p-aminobenzoate, with di-iso-propyl-amino-ethyl paminobenzoate, with diethyl-amino-propyl paminobenzoate, with di-n-butyl-amino-ethyl paminobenzoate, with pyrrolidin-ethyl p-aminobenzoate, with morpholin-ethyl p-aminobenzoate, with di-iso-butyl-amino-ethyl p-aminobenzoate, with piperidin-propyl p-aminobenzoate, with piperidin-ethyl p-aminobenzoate and with di-methyl-amino-propyl p-aminobenzoate. The derivatives are mixed with pharmaceutically acceptable carriers.
