Abstract:
A major secondary metabolite of lichens, diffractaic acid, was found here to exert a significant antiviral action on respiratory syncytial virus strain A2 with a EC50 of 4.8 µM while showing low toxicity to a tested cell line (CC50 of 221.9 µM). We developed methods for the synthesis of derivatives at the hydroxyl group of diffractaic acid and obtained three series of new derivatives: those of diffractaic acid and of its methyl and benzyl esters. We noted that the most promising compounds are derivatives of benzyldiffractate, which typically were found to have same or lower cytotoxicity as compared to either methyldiffractate ethers or compounds with a carboxyl group. A combination of these modifications allowed to find a promising compound: a benzyldiffractate carrying a morpholin-4-yl-ethyl substituent (EC50 2.1 µM, CC50 368.5 µM, SI 175).
