4-Alkyl- and 4-phenylcoumarins from Mesua ferrea as promising multidrug resistant antibacterials

Supercritical CO2 selectively extracted a series of 4-alkyl and 4-phenyl 5,7-dihydroxycoumarins from Mesua ferrea blossoms. Chemical modifications of the isolated compounds allowed us to confirm the structures elucidated by spectroscopic means and to prepare new derivatives amenable to SAR studies and potential pharmaceutical development. Biological investigations towards the screening on a number of bacteria strains and Plasmodium falciparum, identified compounds 1-9 as weak antiprotozoal agents and potent antibacterials on resistant Gram-positive strains.

Synthesis of the calophyllum coumarins

Synthetic routes leading to the synthesis of the natural 4-alkyl and 4- phenyl coumarins isolated from Calophyllum sp. are reported. The reported structures of calanolides C and D and oblongutide are incorrect and have been corrected by unambiguous synthesis.
