Title: Abibalsamins A and B, two new tetraterpenoids from Abies balsamea oleoresin. Author: Lavoie S, Legault J, Gauthier C, Mshvildadze V, Mercier S, Pichette A. Journal: Org Lett; 2012 Mar 16; 14(6):1504-7. PubMed ID: 22394397. Abstract: Abibalsamins A (1) and B (2), two unprecedented tetraterpenoids featuring a 3,4-seco-rearranged lanostane system fused with a β-myrcene lateral chain via a [4 + 2] Diels-Alder cycloaddition, were isolated from the oleoresin of Abies balsamea. Their structures were elucidated by means of extensive 2D NMR, IR, and MS spectroscopy analyses. The absolute configuration of 1 was determined by single-crystal X-ray diffraction. Both compounds exhibited significant cytotoxic activity against cancer cell lines.[Abstract] [Full Text] [Related] [New Search]
