In vitro MGCD0103 inhibits only a subset of the nine human recombinant HDACs, including HDAC1, HDAC2, HDAC3, and HDAC11 at nanomolar or low micromolar concentrations, in a dose-dependent manner. MGCD0103 reveals most potent inhibitory activity against human HDAC1 and HDAC2 enzymes in vitro, and it does not inhibit class II HDACs. The exocyclic amino group in MGCD0103 is necessary for enzyme inhibitory activity because HDAC-inhibitory activity against HDAC1 and HDAC2 is completely abolished with the desamino analogue. The inhibitory activity of MGCD0103 reaches the maximum plateau at 6 μM, and the maximal inhibitable enzyme pool affected by MGCD0103 is 75% of the total enzyme activity in HCT116 cells whereas NVP-LAQ824 inhibits almost 100% of that in these cells. In A549 cells, MGCD0103 also exhibits dose-dependent inhibition of HDAC activity in whole cells. [1]
In vivo MGCD0103 significantly inhibites growth of human tumor xenografts in nude mice and the antitumor activity correlated with induction of histone acetylation in tumors. P.O. administration of MGCD0103 (2HBr salt) significantly decreases growth of implanted advanced A549 tumors in nude mice in a dose-dependent manner after 13 days of daily administration. MGCD0103 (170 mg/kg for 2HBr salt, corresponding to 120 mg/kg of free base) significantly blockes growth of tumors compared with vehicle treatment alone with no change in body weight. In addition, MGCD0103 does not reduce WBC counts and is well tolerated. MGCD0103 is also orally active in many other human tumor xenograft models including NSCLC H1437. MGCD0103 at 80 mg/kg (free base) almost completely blocks the growth of H1437 tumors after 13 days of daily p.o. administration with no reduction of body weight in animals. [1] MGCD0103 reduces pulmonary arterial pressure more dramatically than tadalafil, a standard-of-care therapy for human pulmonary hypertension that functions as a vasodilator. Moreover, MGCD0103 improves pulmonary artery acceleration time and reduced systolic notching of the pulmonary artery flow envelope, which suggests a positive impact of the HDAC inhibitor on pulmonary vascular remodeling and stiffening.

Protocol(Only for Reference)

Kinase Assay: [1]

HDAC enzyme assay in vitro The deacetylase enzyme assay is based on a homogeneous fluorescence release assay. Purified recombinant HDAC enzymes are incubated with MGCD0103 diluted in various concentrations for 10 minutes in assay buffer [25 mM HEPES (pH 8.0), 137 mM NaCl, 1 mM MgCl2, 2.7 mM KCl] at room temperature. The substrate Boc-Lys(ε-Ac)-AMC is added to the reaction for further incubation at 37 °C. The concentration of the substrate and the incubation time varies for different isotypes of HDAC enzymes. A 20-min trypsin incubation at room temperature allows the release of the fluorophore from the deacetylated substrate. The fluorescent signal is detected by fluorometer at excitation of 360 nm, emission of 470 nm, and cutoff at 435 nm.

Cell Assay: [1]

Cell lines Human mammary epithelial cells (HMEC), human foreskin fibroblasts (MRHF) cells
Concentrations 0-60 μM
Incubation Time 72 hours
Method Human mammary epithelial cells (HMEC) and human foreskin fibroblasts (MRHF) cells in 96-well plates are incubated with MGCD0103 at various concentrations for 72 hours at 37 °C in 5% CO2. MTT is added at a final concentration of 0.5 mg/ml and incubated with the cells for 4 hours before an equal volume of solubilization buffer [50% N,N-dimethylformamide, 20% SDS (pH 4.7)] is added. After overnight incubation, solubilized dye is quantified by reading at 570 nm using a reference at 630 nm. Absorbance values are converted to cell numbers according to a standard growth curve of the relevant cell line. The concentration which reduces cell numbers to 50% relative to DMSO-treated cells is determined as MTT IC5

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Incubation Time 48 h
Results In vitro cytotoxicity assays of MCAS control and knockdown cell lines to a panel of HDAC inhibitors currently in clinical and preclinical trials showed enhanced sensitivity of the CtBP2 knockdown cell lines to most of the HDAC inhibitors compared with the control cell line. It is also noted that in the treatment with MGCD0103 and valproic acid, the differences between the control and knockdown cell lines are significant only in the very high doses.

Results Treatments of PANC-1 cells with variable concentrations of MGCD0103 (0–1.0 uM) resulted in a dose-dependent hyperacetylation of histone H4, while having no effects on alpha-tubulin (a HDAC6 substrate) acetylation or total H4 levels (Figure 2A). Treatments with MC1568 also resulted in acetylation of histone H4 (obvious at 5 and 10 uM), however, to a much lesser extent compared to MGCD0103, and the levels of acetylated histone H4 plateaued at 5 and 10 uM. Further, these treatments had no impact on alpha-tubulin acetylation.

Results Treatments with LBH-589, PXD101, and SAHA, but not with MGCD0103 and the other HDACIs, resulted in hyperacetylation ofa-tubulin, the substrate of HDAC6 (Figure A). IP followed by enzymatic assays revealed that both LBH-589 and PXD101 treatments resulted in the greatest inhibition of HDAC1 activities (>80% relative to control), compared to other HDACIs tested (Figure C). This was accompanied by significantly higher extents of proliferation inhibition (as reflected in percent decrease of live cells relative to untreated cells) and apoptosis (Figures E&F). Essentially the same results were obtained in THP-1 cells when the HDACI treatments were extended to 24 h, though the levels of apoptosis induced by the drugs were substantially higher (Figures B, D, E&F)
