Pulcherrimins A – D, novel diterpene dibenzoates from Caesalpinia pulcherrima with selective activity against DNA repair-deficient yeast mutants
Bioassay-guided fractionation of the MeOH/CH 2Cl 2 extract of the roots of Caesalpinia pulcherrima yielded four novel dibenzoate diterpenes, pulcherrimins A, B, C and D (1–4). The structures of these compounds including their absolute configuration were established by interpretation of spectral data...
