CPI-203 Usage And Synthesis
DescriptionCPI-203 is a primary amide analog of (+)-JQ1, which has shown superior bioavailability with oral or i.p. administration. CPI-203 downregulates Myc expression, causes G1 cell cycle arrest and attenuates cell proliferation in human pancreatic neuroendocrine tumors. CPI-203 also arrests the growth of T cell acute lymphoblastic leukemia cells in vitro (EC50 = 91.2 nM).
UsesCPI-203 is a bromodomain and extraterminal domain (BET) inhibitor.
Biological Activitycpi-203 is a potent, selectivie and competitive small molecule inhibitor of bet bromodomain with a mean gi50 value of 0.23μm in mcl cell lines [1].as an inhibitor of bet proteins, cpi-203 inhibits brd4 in vitro and in cells. it inhibits the specific ser2 phosphorylation of both endogenous brd4 and exogenous mutant brd4 (brd4 fee-aaa) in vivo, thus blocking the recruitment of brd4 to chromatin. cpi-203 is shown to suppress cell growth of 9 mcl cell lines. and in rec-1 cells, treatment of cpi-203 causes the effects of irf4 expression. cpi-203 marginally activates the apoptotic program in these cells. the cpi-203-lenalidomide combination is reported to be a promising strategy in mcl cases refractory to proteasome inhibition [1, 2].
in vivo

CPI-203 (2.5 mg/kg, i.p.) combined with lenalidomide, enhances the antitumoral properties of each single agent via the abrogation of MYC and IRF4 expression and the induction of apoptosis in n REC-1 tumor-bearing mice[2].
