A series of new analogues of 3-(9-acridinylamino)-5-hydroxymethylaniline (AHMA, 1) and AHMA-ethylcarbamate (2) were synthesized by introducing an O-alkylcarboxylic acid esters to the CH2OH function, displacing the CH2OH function with a dimethylaminocarboxamido group or with a methyl function introduced at the meta-, para-or ortho-position to the NH2 group to form 5-(9-acridinylamino)-m-toluidines (AMTs), 5-(9-acridinylamino)-p-toluidines ...
