Metabolite Identification
Common NameMomelotinib
DescriptionMomelotinib, also known as CYT-387, belongs to the class of organic compounds known as phenylpyrimidines. These are polycyclic aromatic compounds containing a benzene ring linked to a pyrimidine ring through a CC or CN bond. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. Momelotinib is a moderately basic compound (based on its pKa). Additional potential treatment indications for momelotinib include other myeloproliferative neoplasms, cancer (solid and liquid tumors) and inflammatory conditions. As of 2011, momelotinib is being developed as a drug for myelofibrosis and currently undergoes Phase I/II clinical trials. Momelotinib (INN, formerly GS-0387, CYT-387) is an inhibitor of Janus kinases JAK1 and JAK2, acting as an ATP competitor with IC50 values of 11 and 18 nM, respectively. The drug was originally discovered by Australian drug discovery company Cytopia, then developed by YM BioSciences Inc (since acquired by Gilead Sciences as of 2013). The inhibitor is significantly less active towards other kinases, including JAK3 (IC50 0.16 μM). As of 2016, momelotinib is being investigated for primary myelofibrosis or post-polycythemia vera or post-essential thrombocythemia myelofibrosis (post-PV/ET MF), as well as a treatment for relapsed or refractory metastatic pancreatic ductal adenocarcinoma (in combination with capecitabine and oxaliplatin). This compound has been identified in human blood as reported by (PMID: 31557052 ). Momelotinib is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Momelotinib is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
