ROCK HDAC-IN-1（Compound 10h）作为一种抑制剂，通过口服展现出对ROCK HDAC的有效抑制。该化合物针对ROCK1 2和HDAC1 2 3 6 8表现出卓越的抑制效率，其IC50值分别为254.9 nM、58.18 nM和9.09、8.03、6.26、0.41、7.69 nM。此外，ROCK HDAC-IN-1能激活DAMP，尤其增强了钙网蛋白（CRT）的外露和HMGB1的释放，显示其作为免疫性细胞死亡（ICD）诱导剂的潜力。对于乳腺癌细胞，特别是MDA-MB-231细胞，此抑制剂具有抗增殖活性，IC50值为0.37 μM，且能在不产生明显毒性的情况下，抑制肿瘤生长并激活T细胞。

Givinostat (ITF-2357) is a HDAC inhibitor with an IC50 of 198 and 157 nM for HDAC1 and HDAC3, respectively. Givinostat (ITF2357) suppresses total LPS-induced IL-1β production robustly compared with the reduction by ITF3056. At 25, 50, and 100 nM, Givinostat reduced IL-1β secretion more than 70%. Givinostat (ITF-2357) suppresses the production of IL-6 in PBMCs stimulated with TLR agonists as well as the combination of IL-12 plus IL-18. IL-6 secretion decreases to 50% at 50 nM Givinostat, but at 100 and 200 nM, there is no reduction[1]. As shown by the CCK-8 assay, Givinostat (ITF-2357) inhibits JS-1 cell proliferation in a concentration-dependent manner. Treatment with Givinostat ≥500 nM is associated with significant inhibition of JS-1 cell proliferation (P<0.01). Also, the cell inhibition rate significantly differs between the group cotreated with Givinostat ≥250 nM plus LPS and the group without LPS treatment (same Givinostat concentration) (P<0.05)[2]. Givinostat (ITF2357) at 10 mg kg is used as a positive control and, as expected, reduced serum TNFα by 60%. Strikingly, pretreatment of ITF3056 starting at 0.1 mg kg significantly reduces the circulating TNFα by nearly 90%. To achieve a significant increase in serum IL-1β production, a higher dose of LPS is injected (10 mg kg), and blood is collected after 4 h. Similarly, when pretreated with lower doses of Givinostat (ITF-2357) (1 or 5 mg kg), there is a 22% reduction for 1 mg kg and 40% for 5 mg kg[1]. [1]. Li S, et al.

MPT0G211 mesylate is a powerful and selective HDAC6 inhibitor (IC50 = 0.291 nM), with high oral bioavailability. It exhibits remarkable selectivity for HDAC6 over other HDAC isoforms (>1000-fold selectivity). Additionally, MPT0G211 mesylate can effectively cross the blood-brain barrier. In preclinical studies using an Alzheimer's disease model, MPT0G211 mesylate has shown promising results in reducing tau phosphorylation and cognitive deficits. Furthermore, this compound exhibits anti-metastatic and neuroprotective effects, making it a potential candidate for anticancer interventions. [1] [2] [3].

MHY219 is a novel HDAC inhibitor. MHY219 induces apoptosis via up-regulation of androgen receptor expression in human prostate cancer cells. MHY219 was shown to enhance the cytotoxicity on DU145 cells (IC50, 0.36 μM) when compared with LNCaP (IC50, 0.97 μM) and PC3 cells (IC50, 5.12 μM). MHY219 showed a potent inhibition of total HDAC activity when compared with SAHA. MHY219 increased histone H3 hyperacetylation and reduced the expression of class I HDACs (1, 2 and 3) in prostate cancer cells. MHY219 effectively increased the sub-G1 fraction of cells through p21 and p27 dependent pathways in DU145 cells. MHY219 significantly induced a G2 M phase arrest in DU145 and PC3 cells and arrested the cell cycle at G0 G1 phase in LNCaP cells. Furthermore, MHY219 effectively increased apoptosis in DU145 and LNCaP cells, but not PC3 cells, according to Annexin V PI staining and Western blot analysis. These results indicate that MHY219 is a potent HDAC inhibitor that targets regulating mu......
