scalable synthesis of rooperol and analogues that builds on our previous synthetic approach incorporating a key Pd-catalyzed decarboxylative coupling strategy. Using this approach, we have prepared and evaluated the cancer cellcytotoxicity of rooperol and a series of analogues. While none of the analogues examined here were superior to rooperol in preventing the growth of cancer cells, analogues containing
Pseudomonasaeruginosa (P. aeruginosa) is an opportunistic human pathogen that forms biofilms and produces virulence factors viaquorumsensing (QS). Blocking the QS system in P. aeruginosa is an excellent strategy to reduce biofilm formation and the production of virulence factors. RhlR plays an essential role in the QS system of P. aeruginosa. We synthesized 55 analogues based on the chemical structure

The present invention relates to a 4-gingerol derivative compound, or a racemate, isomer, or pharmaceutically acceptable salt thereof, the compound being capable of inhibiting biofilm formation and production of virulence factors. The 4-gingerol derivative compound according to the present invention has binding affinity to RhlR and corresponding RhlR antagonism activity that are significantly improved, and therefore can effectively inhibit biofilm formation and production of virulence factors. Furthermore, various bacterial infectious diseases caused by biofilms can be fundamentally prevented or treated by using a pharmaceutical composition comprising the 4-gingerol derivative compound, or a racemate, isomer, or pharmaceutically acceptable salt thereof as an active ingredient.
