N-[(3a,5b,7a,12a)-3,12-dihydroxy-24-oxo-7-(sulfooxy)cholan-24-yl]-Glycine is an acyl glycine and a sulfated bile acid-glycine conjugate. It is a secondary bile acid produced by the action of enzymes existing in the microbial flora of the colonic environment. In hepatocytes, both primary and secondary bile acids undergo amino acid conjugation at the C-24 carboxylic acid on the side chain, and almost all bile acids in the bile duct therefore exist in a glycine conjugated form (PMID:16949895). As a bile acid sulfate, N-[(3a,5b,7a,12a)-3,12-dihydroxy-24-oxo-7-(sulfooxy)cholan-24-yl]-Glycine is typically found in urine.

Omacetaxine mepesuccinate is a cephalotaxine-derived alkaloid ester obtained from Cephalotaxus harringtonia; used for the treatment of chronic or accelerated phase chronic myeloid leukaemia. It has a role as an antineoplastic agent, a protein synthesis inhibitor, an apoptosis inducer and an anticoronaviral agent. It is an alkaloid ester, a tertiary alcohol, an organic heteropentacyclic compound and an enol ether. It is functionally related to a cephalotaxine. Omacetaxine mepesuccinate (formerly known as HHT or Homoharringtonine), is a cephalotaxine ester and protein synthesis inhibitor with established clinical activity as a single agent in hematological malignancies. Omacetaxine mepesuccinate is synthesized from cephalotaxine, which is an extract from the leaves of the plant, Cephalotaxus species. In October 2005, omacetaxine mepesuccinate received Orphan Drug designation from the EMEA for the treatment of chronic myeloid leukemia (CML). Then in March 2006, it received Orphan Drug status from the FDA for the treatment of CML. In November 2006, omacetaxine mepesuccinate, for the treatment of CML, was granted Fast Track designation by the FDA. Most recently, in October 2012, omacetaxine mepesuccinate was marketed under the brand name Synribo and FDA approved for patients who are intolerant and/or resistant to two or more tyrosine kinase inhibitors used to treat accelerated or chronic phase CML. Omacetaxine mepesuccinate is a natural product found in Cephalotaxus harringtonia and Cephalotaxus fortunei with data available. Omacetaxine Mepesuccinate is a semisynthetic formulation of the cytotoxic plant alkaloid homoharringtonine isolated from the evergreen tree Cephalotaxus with potential antineoplastic activity. Omacetaxine binds to the 80S ribosome in eukaryotic cells and inhibits protein synthesis by interfering with chain elongation. This agent also induces differentiation and apoptosis in some cancer cell types. Semisynthetic derivative of harringtonine that acts as a protein synthesis inhibitor and induces APOPTOSIS in tumor cells. It is used in the treatment of MYELOID LEUKEMIA, CHRONIC. See also: Omacetaxine (has active moiety). A cephalotaxine-derived alkaloid ester obtained from Cephalotaxus harringtonia; used for the treatment of chronic or accelerated phase chronic myeloid leukaemia.
