Phytochemical investigation of the MeOH extract obtained from the aerial parts of the annual weed Euphorbia exigua L. resulted in the isolation of two novel (1, 2) and one known (3) jatrophane diterpenes. Their structures were established by extensive 1D- and 2D-NMR spectroscopy and HR-ESI-MS. The isolated compounds were evaluated for multidrug resistance (MDR) reversing activity on human MDR gene-transfected L5178 mouse lymphoma cells; and all three compounds were found to modulate the intracellular drug accumulation.
