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].

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

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
