Synthesis and antirhinovirus activity of cyano and amidino substituted flavanoids

Cyano and amidino flavans, isoflavans and 3(2H)-isoflavenes were synthesized in order to study their in vitro antirhinovirus activity, by comparison with the known corresponding chloro derivatives. The activity of the new compounds was evaluated on rhinov
