β¦ Synopsis
Three types of novel triptolide analogues with 9,11-olefin (3-5), five-membered unsaturated lactam ring (6-7) or A/B cis ring junction (8-14) were synthesized. Although with 9,11-olefin instead of 9,11-Ξ²-epoxide, compound 4a was much more active than the parent natural triptolide (1) with the lowest IC(50) value of 0.05nM for SKOV-3 cells, clearly challenging the traditional viewpoint on the necessity of 9,11-Ξ²-epoxide group of triptolide. In addition, structure-activity relationships for three classes of compounds were studied.

Original 1,4-benzoxazine analogues of ellipticine were prepared using a general synthetic route that relied on an anionic ring annulation as the key transformation. The interest of this approach lies on the possibility of an easy entrance to a wide range of derivatives from the phenol intermediate.
