In Vitro

HDAC-IN-45 (Compound 14) suppresses the growth of triple-negative breast cancer cells MDA-MB-231 (IC50 = 1.48 μM), MDA-MB-468 (IC50= 0.65 μM), and liver cancer cells HepG2 (IC50= 2.44 μM).
HDAC-IN-45 has equally virulent in the HDAC-sensitive cell lines (YCC11) and -resistant gastric cell lines (YCC3/7) and overcome HDACi resistance. HDAC-IN-45 has a high toxicity (IC50= 0.33 μM) in three leukemic cell lines, K-562, KG-1 and THP-1.
HDAC-IN-45 (Compound 14) has substantial inhibitory effects towards HDAC1, 2 and 3 isoforms with IC50 values of 0.108, 0.585 and 0.563 μM respectively.
HDAC-IN-45 (Compound 14) can elevate acetylation level of histone H3 and expression of p21.
HDAC-IN-45 (Compound 14) exerts a dose-dependent upregulation of ac-H3K9 in MDA-MB-231 cells, triggers cell cycle arrest in G1 phase.
HDAC-IN-45 (Compound 14) exhibits a potent antitumor efficacy in xenograft mouse model[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.
