Epoxy acetylenic lipids: their analogues and derivatives.

Currently, approximately 250 natural acetylenic epoxy structures are known. The present review describes research concerning biologically active epoxy acetylenic lipids and related compounds isolated from different sources. Intensive searches for new classes of pharmacologically potent agents produced by living organisms have resulted in the discovery of dozens of such compounds that possess high anticancer, cytotoxic, antibacterial, antiviral, and other activities. Acetylenic epoxides primarily belong to a class of molecules containing triple bond(s) and epoxy group(s) belonging to different lipid classes and/or other groups. This review emphasises natural and synthetic acetylenic epoxides and other related compounds as important sources of leads for drug discovery. The present review is the first article devoted to natural acetylenic epoxides.
