生物活性

HDAC/Top-IN-1 is an orally active and pan HDAC/Top dual inhibitor with IC50s of 0.036 μM, 0.14 μM, 0.059 μM, 0.089 μM and 9.8 μM for HDAC1, HDAC2, HDAC3, HDAC6 and HDAC8. HDAC/Top-IN-1 efficiently induces apoptosis with S cell-cycle arrest in HEL cells. HDAC/Top-IN-1 has exhibits excellent in vivo antitumor efficacy[1].

体外研究
(In Vitro)

HDAC/Top-IN-1 (compound 16j) (0-2 μM; 48 hours) exhibits remarkable inhibitory activities against the tested cell lines[1].
HDAC/Top-IN-1 (20 and 100 nM; 24 hours) dramatically increases acetyl-H3 and acetyl-H4 levels in HEL cells[1].
HDAC/Top-IN-1 (0.1 and 0.5 μM; 48 hours) effectively induces HEL cell apoptosis in a dose-dependent manner[1].
HDAC/Top-IN-1 (0.02-0.5 μM; 48 hours) arrests HEL cells at the S phase[1].
