In Vitro

HDAC-IN-47 (compound 21) shows antiproliferative activity and inhibits A549 cell growth with an IC50 value of 0.24 μM[1].
HDAC-IN-47 (0.5 and 1 μM; 72 h) exhibits profound G2/M arrest in A549 cells and induces cell apoptosis[1].
HDAC-IN-47 (0.1 and 0.5 μM; 24 h) increases the expression levels of Bax and Caspase3, decreases the level of Bcl-2, activates the intrinsic (mitochondrial) apoptotic pathway[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.
