Isolation and biological activities of neomyrrhaol and other terpenes from the resin of Commiphora myrrha
Su, SL; Duan, JA; Tang, YP; Zhang, X; Yu, L; Jiang, FR; Zhou, W; Luo, D; Ding, AW
A new cycloartane-type triterpene named cycloartane-1alpha,2alpha,3beta,25-tetraol (neomyrrhaol) (1), along with four known terpenes, sandaracopimaric acid (2), abietic acid (3), 2-methoxy-5-acetoxyfruranogermacr-1(10)-en-6-one (4), and dehydroabietic acid (5) have been isolated from the resin of COMMIPHORA MYRRHA. Their structures were elucidated by means of 1D, 2 D NMR and HR-mass spectroscopy. Compounds 2-5 are known compounds but not previously isolated from the resin of C. MYRRHA. Compounds 4 and 5 exhibited significant aromatase inhibiting activity with IC50 values at 0.2 microM and 0.3 microM, respectively. As shown in the MTT assay, 2, 3, 4, and 5 had inhibitory effects on HUVEC growth with IC50 values of 0.122 microM (2), 0.125 microM (3), 0.069 microM (5). Compounds 1-5 did not inhibit contraction of the isolated uterine and did not protect HUVEC from damage induced by H2O2 at the tested concentration.

Will search more later, but I'm sure Coop has some wealth.
