Homoharringtonine is a natural alkaloid derived from the evergreen tree Cephalotaxus harringtonia, primarily used in cancer research and clinical applications for its potent anti-leukemic properties, particularly in treating chronic myeloid leukemia. It inhibits protein synthesis by binding the A-site cleft of the peptidyl transferase centre on the large (60S) ribosomal subunit, blocking translation elongation and disrupting tumor cell growth. This compound has a CAS number of 26833-87-4, with the molecular formula C29H39NO9 and a molecular weight of 545.62 g/mol. It must be stored at -15 to -20°C and is classified with a Danger signal word due to its toxicity. Molekula supplies Homoharringtonine from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
