Studies on the regio- and diastereo-selective epoxidation of daphnanes and tiglianes
摘要:
Daphnanes and tiglianes are diterpenes with a shared tricyclic 5-7-6 ring system. Many members exhibit significant biological activities often associated with protein kinase C signaling. Many of these natural products (similar to 100) have a C6-C7 alpha-epoxide whose influence on biological activity is little studied. Using the more readily available phorbol ester PDBu as a test substrate, we report an efficient, and potentially general, alpha-epoxidation method based on a vanadium-catalyzed asymmetric epoxidation with bishydroxamic acid (BHA) ligands.

The present invention relates to tripartite compounds comprising a modulator moiety for endosomal G protein-coupled receptors like neurokinin-1 receptor, a linker and a lipid anchor suitable for anchoring the tripartite compound into a plasma membrane. The present invention also relates to a prodrug and a pharmaceutical composition comprising the tripartite compound and the use of the tripartite compound for the treatment of a disease or disorder mediated by endosomal G protein-coupled receptors signalling like NK1R signalling.
