3-O-(alpha-L-olivosyl)oleandolide is a macrolide that is oleandolide having a 2,6-dideoxy-alpha-L-arabino-hexopyranosyl (alpha-L-olivosyl) residue attached at position 3. It has a role as a metabolite. It is a macrolide, a glycoside and a monosaccharide derivative. It is functionally related to an oleandolide. L-Olivosyl-oleandolide is a naturally occurring sesquiterpene lactone derivative that contains an olivosyl moiety, which is a specific type of ester derived from olivolic acid. The "L" in the name indicates that the olivosyl group is in the L-configuration, which refers to the spatial arrangement of atoms around the chiral center in the molecule. This compound is an example of a glycosylated sesquiterpene lactone, where the sesquiterpene lactone oleandolide is modified by the attachment of the olivosyl group. The presence of the olivosyl group can alter the biological properties of the parent compound, oleandolide, potentially affecting its pharmacological activities such as cytotoxicity, anti-inflammatory effects, and antimicrobial activity. L-Olivosyl-oleandolide can be found in certain plant species and may contribute to the plant's defense mechanisms against pathogens and herbivores. In its chemical structure, L-Olivosyl-oleandolide consists of a sesquiterpene lactone core with a lactone ring fused to a sesquiterpene framework, and it is appended with the L-olivosyl ester group, which adds complexity to its molecular structure and function. This compound is of interest in the fields of natural products chemistry and pharmacognosy for its potential therapeutic applications and as a subject of study for understanding the biosynthesis of such natural products.

Emetine Hydrochloride is the chloride salt of a white crystalline bitter alkaloid isolated from the root of the plant Psychotria Ipecacuanha (ipecac root) and other plants with antiemetic and anthelminthic properties. Emetine inhibits protein synthesis in eukaryotic (but not prokaryotic) cells by irreversibly blocking ribosome movement along the mRNA strand and inhibits DNA replication in the early S phase of the cell cycle. (NCI04) The principal alkaloid of ipecac, from the ground roots of Uragoga (or Cephaelis) ipecacuanha or U. acuminata, of the Rubiaceae. It is used as an amebicide in many different preparations and may cause serious cardiac, hepatic, or renal damage and violent diarrhea and vomiting. Emetine inhibits protein synthesis in EUKARYOTIC CELLS but not PROKARYOTIC CELLS.
