sesterterpenoid scaffolds have been overlooked. Meanwhile, the recent identification of the first sesterterpenesynthase has allowed the discovery of new sesterterpenoids by the genome mining approach. In this study, we characterized the unusual fungal sesterterpenesynthase EvQS and successfully obtained the sesterterpene quiannulatene (1) with a novel and unique highly congested carbon skeleton, which is further
Methods of treatment and prophylaxis of various diseases and disorders, and in particular diseases and disorders of lipid and bone metabolism, involving the administration of prenyl transferase (farnesyl pyrophosphate synthase) and/or isopentenyl pyrophosphate isomerase inhibitor compounds are disclosed.
Disclosed are isolated nucleic acid molecules from
Selaginella moellendorffii
that encode a terpene synthase protein at least 80% identical to a protein encoded by the nucleic acid sequence according to any of SEQ ID NOs: 1-47 or a degenerate variant thereof or a functional fragment thereof. Isolated terpene synthase proteins from
S. moellendorffii
are also disclosed. Host cells transformed with the
S. moellendorffii
terpene synthase nucleic acids are also disclosed, for example cells of a single cell organism, such as bacteria and yeast, or multicellular organism, such as a plant. The host cells can be prokaryotic cells or eukaryotic cells. Transgenic plants, or any part thereof, stably transformed with
S. moellendorffii
terpene synthase nucleic acids are also disclosed In some examples the transgenic plant is a dicotyledon or a monocotyledon. A method is disclosed for producing a transgenic plant, as is a method for producing terpenes.

The mevalonate pathway is an important drug target for the treatment of cancer and cardiovascular disease. We synthesized and studied a new type of nitrogen-containing bisphosphonate analogs and developed a sensitive end point assay method for enzyme FPPS, which was used for inhibitor screening. One potent FPPS inhibitor was discovered, and the structure-activity relationship of bisphosphonates for
Five DMAPP analogs with additional carbon atoms or with changed methylation patterns were converted with IPP and the bifunctional variediene synthase from Aspergillus brasiliensis AbVS to yield diterpene analogs with unusual skeletons. The DMAPP analogs opened new reaction pathways through the stabilisation of cationic charges at alternative carbon atoms that are naturally not observed.
