Cinnamoyl pyrones (CP) (3-[(2E)-3-(4-R-phenyl)-1-oxo-2-
propenyl]-4-hydroxy-6-methyl-2H-pyran-2-ones) are structural
analogs of 2
-hydroxychalcones, which manifest various aspects
of biological activity. It is found that CP and its derivatives have
blood-platelet aggregation inhibiting activity [1] and were used
as I type collagen gene transcription suppressing agents [2].
Difluoroborate complexes of CP derivatives are known as a novel
class of HIV-1 integrase inhibitors [3]. CP can also be used as
intermediate products in synthesis of many oxygen and nitrogen
containing heterocyclic compounds [4]. Some of them, for example
thiazepines [5], are used as apoptosis inducers.
