What is HARRINGTONINE?

Description

The full structure of harringtonine has now been established from a study of the hydrolysis products of this base.

Description

Harringtonine is a natural alkaloid that inhibits protein synthesis at low micromolar concentrations. It immobilizes ribosomes immediately after the initiation of translation. While harringtonine has drawn some interest in mitigating cancer, its homolog homoharrington is more effective, particularly for chronic myelogenous leukemia. The ability of harringtonine to immobilize initiating ribosomes can be used to capture ribosome-protected mRNA fragments for evaluating translation.
