Givinostat HCl hydrate | CAS#199657-29-9 | HDAC Inhibitor

MedKoo Cat#: 526293 | Name: Givinostat HCl hydrate

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Givinostat (ITF-2357) is a hydroxamic acid-based histone deacetylase (HDAC) inhibitor with potent anti-inflammatory and antineoplastic activity. It selectively inhibits class I and II HDACs, leading to accumulation of acetylated histones, modulation of gene expression, and apoptosis in malignant cells. In vitro, Givinostat has demonstrated IC₅₀ values in the low nanomolar range for HDAC1 (10 nM) and HDAC2 (7.5 nM), with minimal activity against class III HDACs. It effectively suppresses pro-inflammatory cytokines such as TNF-α, IL-1β, and IL-6 in monocytes and macrophages. Clinically, it has shown efficacy in hematological malignancies, particularly polycythemia vera, where it reduces JAK2^V617F allele burden and improves hematologic parameters.

Biological target:

Givinostat hydrochloride monohydrate (ITF-2357 hydrochloride monohydrate) is a HDAC inhibitor with an IC50 of 198 and 157 nM for HDAC1 and HDAC3, respectively.

In vitro activity:

Givinostat significantly inhibited JS-1 cell proliferation and promoted cell apoptosis, leading to cell cycle arrest in G0/G1 phases. Treatment with givinostat downregulated protein expression of CDK4, CDK6, and cyclin D1, whereas expression of p21 and p57 was significantly increased. The givinostat-induced apoptosis of hepatic stellate cells was mainly mediated through p38 and extracellular signal-regulated kinase 1/2. Givinostat treatment increased intracellular reactive oxygen species production, decreased mitochondrial membrane potential, and promoted mitochondrial permeability transition pore opening. Acetylation of superoxide dismutase (acetyl K68) and nuclear factor-κB p65 (acetyl K310) was upregulated, while there was no change in protein expression. Moreover, the notable beneficial effect of givinostat on liver fibrosis was also confirmed in the mouse models.

In vivo activity:

Mice were given 100 μL water or ITF2357 (5 mg/kg) by gavage and, after 1 h, injected intravenously with 200 μg/mouse of ConA. Control mice received an intravenous injection of saline. Mice were bled 24 h later for evaluation of serum ALT levels as described previously (33,34). As shown in Figure 15, ALT levels were reduced by more than 80% by ITF2357 pretreatment. In another experiment, a comparison was made between 1 and 10 mg/kg of oral ITF2357. As shown in Figure 16, a dose of 1 mg/kg ITF2357 was as effective as a dose of 10 mg/kg in reducing ConA hepatitis as measured by ALT levels.
