Abstract:

Curcumin, a relatively non-toxic natural product isolated from Curcuma longa, is a modest inhibitor of the HIV-1 (IC50 = 100 microM) and HIV-2 (IC50 = 250 microM) proteases. Simple modifications of the curcumin structure raise the IC50 value but complexes of the central dihydroxy groups of curcumin with boron lower the IC50 to a value as low as 6 microM. The boron complexes are also time-dependent inactivators of the HIV proteases. The increased affinity of the boron complexes may reflect binding of the orthogonal domains of the inhibitor in interesecting sites within the substrate-binding cavity of the enzyme, while activation of the alpha, beta-unsaturated carbonyl group of curcumin by chelation to boron probably accounts for time-dependent inhibition of the enzyme.
