Preliminary evaluation of inhibition of matrix-metalloprotease MMP-2 and MMP-9 by Passiflora edulis and P foetida aqueous extracts.

Fruit's decoctions of Passiflora edulis and P. foetida var. albiflora were evaluated for the inhibition of activity of gelatinase MMP-2 and MMP-9, two metallo-proteases involved in the tumour invasion, metastasis and angiogenesis. Both water extracts, at different concentrations, inhibited the enzymes.
