Chalcone (1,3-diphenylprop-2-en-1-one) and its derivatives show numerous biological activities. In this review, their effects on aldose reductase, the enzyme that plays an important role in pathogenesis of secondary diabetic complications, are described. The highest potency was observed for derivatives with hydroxy derivatives in positions 2 and 4 of ring A, whilst the substitution pattern in the other ring seems to be less important. Structure - activitity studies have also revealed that the presence of the enone grouping is not necessary for the inhibition of aldose reductase. Hence, corresponding dihydrochalcones could be used to prevent possible side effects resulting from the high reactivity of the enone grouping.
