Abstract
In an effort to discover novel anti-trypanosomal compounds, a series of podophyllotoxin analogues coupled to non-steroidal anti-inflammatory drugs (NSAIDs) has been synthesized and evaluated for activity versus Trypanosoma brucei and a panel of human cell lines, revealing compounds with low nano-molar potencies. It was discovered that coupling of NSAIDs to podophyllotoxin increased the potencies of both compounds over 1300-fold. The compounds were shown to be cytostatic in nature and seem to act via de-polymerization of tubulin in a manner consistent with the known activities of podophyllotoxin. The potencies against T. brucei correlated directly with Log P values of the compounds, suggesting that the conjugates are acting as hydrophobic tags allowing podophyllotoxin to enter the cell.
