The 70% aqueous methanolic extract of the Peruvian plant Polygonum cuspidatum sp. was found to contain two novel phenolic saccharides 1 and 2, which were identified as inhibitors of the bacterial DNA primase enzyme. Structures of these two compounds were established based on high resolution NMR studies. Compound 1 and 2 inhibited the primase enzyme with an IC(50) of 4 and 5 microM, respectively.
