Customer Review

    Poziotinib purchased from MCE. Usage Cited in: Cancers (Basel). 2020 Nov 4;12(11):3249.  [Abstract]

    Poziotinib, at 0.1, 0.3 and 0.6 μM, produces a significant decrease in the expression level of the ABCG2 transporter protein in S1-M1-80 cells after 72 h of incubation, compared to cells incubated with vehicle (0 μM). ABCG2 protein expression is significantly decreased in S1-M1-80 cells following incubation with 0.6 µM of Poziotinib for 48 or 72 h.

    生物活性

    Poziotinib (HM781-36B) is an orally active, irreversible pan-HER inhibitor, which effectively inhibits EGFRwt, HER-2 and HER-4 with IC50s of 3.2, 5.3 and 23.5 nM, respectively. Poziotinib (HM781-36B) also shows excellent inhibitory activities against mutated EGFRs, including EGFRT790M and EGFRL858R/T790M, with IC50s of 4.2 and 2.2 nM, respectively. Excellent antitumor activity[1][2].

    IC50 & Target

    IC50: 3.2 nM (EGFRwt), 5.3 nM (HER-2), 23.5 nM (HER-4) 4.2 nM (EGFRT790M), 2.2 nM (EGFRL858R/T790M)[2]

    体外研究
    (In Vitro)

    The IC50 levels of Poziotinib (HM781-36B) for N87 and SNU216 were 0.001 and 0.004 μM, respectively, which was 10-1000 fold lower than the IC50 levels of other HER family TKIs. HM781-36B more potently inhibited the phosphorylation of HER family and downstream proteins, and induced apoptosis and G1 arrest compared to ZD1839 or GW572016[1].
    Poziotinib (HM781-36B) also shows excellent selectivity with other kinases with greater than 100- to 1,000- fold IC50 values compared with EGFR family members. Poziotinib (HM781-36B) possesses a functional α,β‐unsaturated carbonyl group as Michael acceptor moiety at the C6 position that allows covalent modifications of the EGFR kinase domain active site[2].
    The addition of HM781-36B induced potent growth inhibition in both DiFi cells with EGFR overexpression and SNU-175 cells (IC50=0.003 and 0.005 μM, respectively). Furthermore, HM781-36B induced G1 arrest of the cell cycle and apoptosis, and reduced the levels of HER family and downstream signaling molecules, pERK and pAKT, as well as nonreceptor/cytoplasmic tyrosine kinase, BMX[3].

    体内研究
    (In Vivo)

    The growth of tumors in mice treated with HM781-36B alone or in combination with 5-FU was significantly inhibited compared with control mice, and tumor volume in mice receiving coadministraion of HM781-36B and 5-FU was smaller than tumor volume in mice receiving HM781-36B only[1].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
