The cytotoxic activities of new 2-alkyl-4,6-dihetero-(N,O)alkyl-1,3,5-triazines toward selected tumor cell lines have been evaluated, and for the first time, the potential of 2-alkyl-4,6-dialkoxy-1,3,5-triazines has been shown.

Hexakis(2,3-di-O-benzoyl)-α-cyclodextrin and hexakis(2,3,6-tri-O-benzoyl)-α-cyclodextrin have been employed as chiral solvating agents (CSAs) for the NMR determination of the enantiomeric composition of derivatives of chiral amines, amino alcohols, alcohols, carboxyl acids, and amino acids bearing a 3,5-dinitrophenyl moiety. The conformational features of the two cyclodextrins have been carefully analyzed by NMR spectroscopy, and the origin of the symmetry change (C 6 → C 3), detected by NMR for hexakis(2,3-di-O-benzoyl)-α-cyclodextrin in CDCl3, has been clarified.
