Protein Binding
Plasma protein binding is equal or less than 50%.
Pharmacodynamics
The pharmacodynamics of homoharringtonine is not fully understood. It is known that homoharringtonine is involved with protein synthesis inhibition and this leads to its antineoplastic activity.
Mechanism of Action
Homoharringtonine inhibits protein synthesis by not directly binding to Bcr-Abl. It binds to the A-site cleft in the large ribosomal subunit, which affects chain elongation and prevents protein synthesis.
Biological Half-Life
Homoharringtonine has a half life of about 6 hours after subcutaneous administration.
Metabolism/Metabolites
Homoharringtonine has undergoes little hepatic metabolism and is mostly metabolized to 4’-DMHHT by plasma esterase hydrolysis.
MeSH Pharmacological Classification
Agents obtained from higher plants that have demonstrable cytostatic or antineoplastic activity.
Compounds which inhibit the synthesis of proteins. They are usually ANTI-BACTERIAL AGENTS or toxins. Mechanism of the action of inhibition includes the interruption of peptide-chain elongation, the blocking the A site of ribosomes, the misreading of the genetic code or the prevention of the attachment of oligosaccharide side chains to glycoproteins.
Absorption, Distribution and Excretion
Homoharringtonine absorption was not quantified, but maximum concentration is reached after about 30 mins.
The main route of elimination for homoharringtonine is still unknown, but renal elimination is less than 15%.
Homoharringtonine has a steady state Vd of 141 ± 93.4 L.
Clearance for homoharringtonine was not quantified.
