Abstract

Preclinical Research A novel series of ten 5-hydroxy, 5-substituted benzene sulfonamide pyrimidine-2,4,6-triones were synthesized and their structures ascertained using (1) H-NMR, (13) C-NMR, mass and elemental analysis. These compounds were subsequently tested for inhibition of MMP-2 and MMP-9 where most exhibited activity with compound 5i being the most potent against MMP-2 and MMP-9 with IC50 values of 2.35 nM and 8.24 nM, respectively. Compound 5i was further analyzed in a mouse LPS-induced acute lung injury model where it had protective activity. Histochemical studies indicated that 5i improved the vascular integrity of the lung.
