Theophylline (1,3-Dimethylxanthine) is a methyl xanthine derivative from tea with diuretic, smooth muscle relaxant, bronchial dilation, cardiac, and central nervous system stimulant activities. It inhibits the 3', 5'-cyclic nucleotide phosphodiesterase that degrades cyclic AMP, thus potentiating the actions of agents that act through adenylyl cyclases and cyclic AMP.

Vorinostat (SAHA) is a pan-histone deacetylase (HDAC) inhibitor (IC50=10 nM) with inhibitory activity against HDAC1/2/3/6/7/11. Vorinostat has antitumor activity, induces cell differentiation, blocks the cell cycle and induces apoptosis.

Tucidinostat (Chidamide) is an effective and orally bioavailable HDAC enzymes class I (HDAC1/2/3) and class IIb (HDAC10) inhibitor, with IC50s of 95, 160, 67 and 78 nM, less active on HDAC8/11 (IC50: 733/432 nM), and shows no effect on HDAC4/5/6/7/9.

Romidepsin (FR 901228) is an HDAC inhibitor that inhibits HDAC1/2/4/6 (IC50=36/47/510/1400 nM). Romidepsin has antitumor activity and can be used for the treatment of peripheral T-cell lymphoma and cutaneous T-cell lymphoma.

ACY-957 (HDAC Inhibitor C001) is an orally active and selective inhibitor of HDAC1 and HDAC2 (IC50s: 7 nM, 18 nM, and 1300 nM against HDAC1/2/3) and shows no inhibition on HDAC4/5/6/7/8/9.

Theophylline monohydrate (Quibron) appears to inhibit phosphodiesterase and prostaglandin production, regulate calcium flux and intracellular calcium distribution, and antagonize adenosine. Theophylline monohydrate is a natural alkaloid derivative of xanthine isolated from the plants Camellia sinensis and Coffea arabica. Physiologically, this agent relaxes the bronchial smooth muscle, produces vasodilation (except in cerebral vessels), stimulates the CNS, stimulates the cardiac muscle, induces diuresis, and increases gastric acid secretion; it may also suppress inflammation and improve contractility of the diaphragm.

Valproic acid sodium salt (Sodium Valproate) is the sodium salt form of valproic acid with anti-epileptic activity. Valproic acid sodium salt is converted into its active form, valproate ion, in blood. Although the mechanism of action remains to be elucidated, Valproic acid sodium salt increases concentrations of gamma-aminobutyric acid (GABA) in the brain, probably due to inhibition of the enzymes responsible for the catabolism of GABA. This potentiates the synaptic actions of GABA. Valproic acid sodium salt may also affect potassium channels, thereby creating a direct membrane-stabilizing effect.

Tacedinaline (CI994) is a selective class I HDAC inhibitor with potential antineoplastic activity.

Acefylline (Theophylline-7-acetic acid), a stimulant drug of the xanthine chemical class, acts as an adenosine receptor antagonist. It is combined with diphenhydramine in the pharmaceutical preparation Etanautine to help offset its stimulant effects

Imofinostat (MPT0E028) is a selective, orally available pan-HDAC inhibitor with IC₅₀ values of 53.0/106.2/29.5 nM against HDAC1/HDAC2/HDAC6 in HCT116 cells. In B-cell lymphoma, Imofinostat induces cell cycle arrest and apoptosis whilst inhibiting Akt phosphorylation, demonstrating anticancer activity across multiple tumour types.

BG45 is an HDAC I type inhibitor with IC50 of 289 nM, 2.0 μM, 2.2 μM and >20 μM for HDAC3/1/2/6 in cell-free assays, respectively.

PCI-24781 (Abexinostat (PCI24781)) is a new pan-HDAC inhibitor mainly targeting HDAC1 (Ki: 7 nM), also have moderate inhibitory for HDACs 2, 3, 6, and 10 and greater than 40-fold selectivity against HDAC8. Phase 1/2.

CRA-026440 is a highly potent HDAC inhibitor with inhibitory effects on HDAC1, HDAC2, HDAC3, HDAC6, HDAC8 and HDAC10 with Ki values of 4,14,11,15,7 and 20 nM, respectively. CRA-026440 has anti-tumor and anti-angiogenic activity and can be used to study colon cancer.

PI3K/HDAC-IN-1 is a potent dual inhibitor of PI3K and HDAC, with IC50 values of 8.1 nM and 1.4 nM, respectively.

RTS-V5 is a dual inhibitor of HDAC/proteasome (IC50s: 6.9, 18, 15, 0.27, 0.53 μM for HDAC1, HDAC2, HDAC3, HDAC6, HDAC8, respectively).

SW-100 is a selective histone deacetylase 6 inhibitor (IC50: 2.3 nM). It also shows at least 1000-fold selectivity for HDAC6 relative to all other HDAC isozymes. SW-100 displays an obviously improved ability to cross the blood-brain-barrier.

Pracinostat (SB939) is a novel HDAC inhibitor with improved in vivo properties compared to other HDAC inhibitors currently in Clinicalal trials, allowing oral dosing. Data demonstrate that Pracinostat is a potent and effective anti-tumor drug with potential as an oral therapy for a variety of human hematological and solid tumors.

HDAC-IN-7, an analogue of Tucidinostat (Chidamide), is a HDAC inhibitor. HDAC-IN-7 inhibits acetylation of histone protein H3 and induces apoptosis in human colon cancer cell lines[1].

Fimepinostat (CUDC 907) is an orally bioavailable inhibitor of both phosphoinositide 3-kinase (PI3K) class I and pan-histone deacetylase (HDAC) enzymes, with potential antineoplastic activity. Upon oral administration, CUDC-907 inhibits the activity of both PI3K class I isoforms and HDAC, thereby preventing the activation of the PI3K-AKT-mTOR signal transduction pathway that is often overactivated in many cancer cell types.
