HDAC8-IN-18
HDAC8-IN-18 is an orally active HDAC8/PI3Kα inhibitor (IC50 = 0.84 µM for HDAC8; IC50 = 109.32 µM for PI3Kα). HDAC8-IN-18 targets HDAC8-mediated deacetylation of histone and non-histone lysine residues and PI3K/Akt lipid signaling, and inhibits the checkpoint kinase CHEK2, thereby inducing Apoptosis and exerting antiproliferative effects on cervical cancer cells. HDAC8-IN-18 inhibits tumor growth in a cervical cancer xenograft model, shows low cytotoxicity toward normal liver and kidney cell lines, and exhibits no teratogenic effects in zebrafish embryos. HDAC8-IN-18 can be used for research on cervical cancer.

In Vitro
HDAC8-IN-18 (2 μM; 24 h) alters the expression of 162 genes in HeLa cells and enriches the PI3K-Akt signaling pathway[1].
HDAC8-IN-18 (2-8 μM; 48 h) inhibits the phosphorylation of PI3K/AKT/mTOR and HDAC8 in HeLa cells in a dose-dependent manner, while increasing Ac-SMC3[1].
HDAC8-IN-18 (6.25-100 μM) binds HDAC8 in BLI with a Kd of 4.21 × 10-6 M and binds PI3Kα with a Kd of 3.81 × 10-5 M[1].
HDAC8-IN-18 (10 μM) shows 89.2% inhibition of CHEK2 across a panel of 80 kinases[1].
HDAC8-IN-18 (4 μg/mL; 15-120 min) has a half-life of 67 min in rat plasma, with 37.20% remaining at 120 min[1].

Animal Model:BALB/c nude (female, 6 weeks old, 18-20 g)[1]
-
Dosage:15 mg/kg (i.p.); 30 mg/kg (i.p.); 60 mg/kg (i.p.); 25 mg/kg (i.g.); 50 mg/kg (i.g.); 100 mg/kg (i.g.)
-
Administration:i.p.; i.g.; once daily for 14 days
-
Result:Produced dose-dependent inhibition of tumor growth in the HeLa xenograft model.
Tumor growth inhibition reached 88.4% at 60 mg/kg i.p. and 57.1% at 100 mg/kg i.g. (p.o.); the i.p. route showed better efficacy than i.g.
Immunohistochemistry showed reduced p-PI3K and HDAC8 expression in tumor tissues, and TUNEL assay indicated induction of apoptosis.
