A series of receptors containing phenylboronic acid and urea or thiourea units have been designed for simultaneousrecognition of the cis-diol and carboxylatefunctions of sialicacids, which are known to be overexpressed on the surfaces of tumor cells. The interaction of the receptors with 5-acetylneuraminic acid (Neu5Ac) and 2-α-O-methyl Neu5Ac (MeNeu5Ac) in DMSO solution has been investigated bymeans
