Nb. Pham et al., Anthoptilides A-E, new briarane diterpenes from the Australian sea pen Anthoptilum cf. kukenthali, J NAT PROD, 63(3), 2000, pp. 318-321
The Australian sea pen Anthoptilum cf. kukenthali has afforded five new bri
arane-type diterpenes, anthoptilides A-E. Their structures were determined
on the basis of their spectroscopic data. Single-crystal X-ray determinatio
n was performed on anthoptilide A. Anthoptilides B and C inhibited the bind
ing of [H-3]1,3-dipropyl-8-cyclopentylxanthine ([H-3]DPCPX) on adenosine A(
1) receptors.
