The formation of a tri-base pairing from free nucleobases is rare. A co-crystal structure obtained from an equimolar mixture of 6-isopropyluracil and adenine shows the formation of a tri-base pairing, where one molecule of free adenine is adhered to two molecules of the free pyrimidine nucleobase, involving both Watson-Crick and Hoogsteen base-pairing interactions.

, p. 514 - 539 (2007/10/02)
A series of 6-substituted 2,4-diamino-5-(4-pyridylamino)pyrimidines and of 2,4-diamino-5-(4-substituted benzylamino)pyrimidines has been prepared.Their antibacterial activity towards L. casei, S. aureus and E. coli has been investigated.These activities have been successfully correlated by Hansch-type relations.Dependence on both lipophilicity and electronic (polar) factors has been found.The results are related to the structure and interactions with the receptor.
