Natural products had always be an important source of new hits and leads in drug discovery. The marine environment has been regarded as a significant souce of novel and exquisite bioactive compounds. Yicathins B and C are two marine derived xanthones that have shown antibacterial and antifungal activities. Herein, the total synthesis of these yicathins is reported for the first time as well as six novel analogues. As marine natural products tend to bear very lipophilic scaffolds, the lipophilicity of yicathins and its analogues was
evaluated using the classical octanol:water system and a biomimetic model based system. As the xanthonic nucleus is a “privileged structure”, other biological activities were evaluated, namely antitumor and anti-inflammatory activities. An interesting anti-inflammatory activity was identified for yicathins analogues that paves the way for the design of dual activity (anti-infective and anti-inflammatory) marine inspired xanthones derivatives.
