Additionally, HDAC6-IN-44 reduces fibrogenesis in a bleomycin-induced pulmonary fibrosis mouse model and demonstrates good metabolic stability. HDAC6-IN-44 holds promise for research in the field of idiopathic pulmonary fibrosis.

HDAC11-IN-1 (Compound 14-N^C6OH) is a selective macrocyclic inhibitor of HDAC11 with a K_i of 40 nM. HDAC11-IN-1 exhibits good cell permeability and can inhibit the expression of YAP1 and SOX2.

FT234 is a HDAC11 inhibitor with an IC₅₀ of <0.5 μM. FT234 can be used for the research of cancer.

JAK/HDAC-IN-2 is a potent 2-amino-4-phenylaminopyrimidine JAK/HDAC dual-target inhibitor. JAK/HDAC-IN-2 potently inhibits HDAC3/6 and JAK1/2 at nanomolar levels. JAK/HDAC-IN-2 has proapoptotic activity and inhibits histone deacetylation and STAT3 phosphorylation. JAK/HDAC-IN-2 presents remarkable antiproliferative activity in both hematological malignancies and solid cancers.

Tubulin/HDAC-IN-1 is a dual tubulin and HDAC-IN-1 inhibitor through CH/π interaction with tubulin and hydrogen bond interaction with HDAC8. Tubulin/HDAC-IN-1 inhibits tubulin polymerization and selectively inhibits HDAC8 (IC₅₀: 150 nM). Tubulin/HDAC-IN-1 has cytotoxicity against various human cancer cells, also arrests cell cycle in the G2/M phase and induces cell apoptosis. Tubulin/HDAC-IN-1 can be used in the research of hematologic and solid tumors such as neuroblastoma, leukemia.

ZG-126 is an agonist for vitamin D receptor (VDR) and an inhibitor for histone deacetylase (HDAC) (IC₅₀=0.63-67.6 μM). ZG-126 exhibits cytotoxicity in cancer cells MDA-MB-231 and 4T1. ZG-126 exhibits antitumor and anti-metastatic efficacy against melanoma and triple-negative breast cancer (TNBC) in mouse models. ZG-126 also exhibits anti-inflammatory activity, through the reduction of macrophage infiltration and immunosuppressive M2-polarization.

JN210 is a dual inhibitor of DCN1 and HDAC, with an IC₅₀ of 94.26 nM against human DCN1. JN210 disrupts the UBE2M-DCN1 protein-protein interaction, blocks the neddylation modification of cullin-RING ligases, inhibits HDAC activity and induces histone hyperacetylation. JN210 impairs DNA damage repair function, induces cell apoptosis, exerts cytotoxicity and inhibits tumor growth. JN210 can be used for the research of non-small cell lung cancer.

HDAC-IN-84 (compound 4d) is a potent HDAC inhibitor, with IC₅₀ values of 0.0045, 0.015, 0.013, 0.038, 5.8 and 26 μM for HDAC1, HDAC2, HDAC3, HDAC6, HDAC8 and HDAC11, respectively. HDAC-IN-84 effectively inhibits the proliferation of leukemia cells without causing toxicity.

Quisinostat (JNJ-26481585) hydrochloride is a potent and orally active pan-HDAC inhibitor (HDACi), with IC₅₀ values ranging from 0.11 nM to 0.64 nM for HDAC1, HDAC2, HDAC4, HDAC10 and HDAC11. Quisinostat hydrochloride has a broad spectrum antitumoral activity. Quisinostat hydrochloride can induce autophagy in neuroblastoma cells.

CM-444 is inhibitor for HDAC (IC₅₀ is 6 nM-0.6 μM) and DNA methyltransferases (DNMT, IC₅₀ is 1.8-2.3 μM). CM-444 is an inducer for the differentiation of acute myeloid leukemia cells. CM-444 exhibits anti-leukemic activity and improves the survival rate in mouse models.

HDAC6-IN-74 is an orally active, selective histone deacetylase 6 (HDAC6) inhibitor with an IC₅₀ of 0.036 μM. HDAC6-IN-74 induces tumor cell apoptosis, arrests cells at the S phase of the cell cycle, and impairs cell migration, invasion and colony-forming abilities. HDAC6-IN-74 exerts anticancer effects with no obvious toxicity. HDAC6-IN-74 can be used in the research of cancers such as liver cancer.
