Abstract

Phytochemical analysis of Euphorbia gedrosiaca Rech.f., Aellen & Esfand., an Iranian endemic spurge, afforded the isolation of four myrsinane types diterpene polyesters. Two new compounds (1–2) were based on a myrsinane skeleton while the others (3–4) were known diterpenes based on a cyclomyrsinane backbone. Their chemical structures were elucidated by spectroscopic methods, including 1D and 2D NMR and HRESIMS. The isolated compounds were tested to evaluate their cell growth inhibitory activity and apoptotic effects on melanoma cell lines, B16F10 and A375. The IC50 values for compounds 1–4 were 58.45, 55.43, 86.52 and 82.27 μM, respectively, on B16F10, and 20.66, 21.88, 36.21 and 39.87 μM, respectively, on A375 cells. Non-treated cells were used as negative control (100% cell growth) and 5 nM Taxol were considered as a positive control. © 2022 Elsevier B.V.
