生物活性

Guadecitabine (SGI-110) is a second-generation DNA methyltransferases (DNMT) inhibitor for research of acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS)[1].

IC50 & Target[1]

DNA Methyltransferase

 

体外研究
(In Vitro)

Exposure to Guadecitabine induces the expression of investigated cancer/testis antigens (CTA) in CTA-negative cancer cells. Results show that Guadecitabine induces and/or strongly up-regulates the constitutive levels of MAGE-A3- and NY-ESO-1-specific mRNA expression in neoplastic cells of all histotypes investigated. Exposure to Guadecitabine significantly (p<0.05) up-regulates the constitutive levels of expression of HLA class I antigens, HLA-A2 allospecificity, and of the co-stimulatory molecule ICAM-1, on Mel 275 melanoma cells. Results show that treatment with Guadecitabine induces a significant (p<0.01) reduction in the constitutive methylation levels of CTA promoters in investigated cancer cells. Mean values of the percentage of demethylation induced by Guadecitabine in MAGE-A1 and NY-ESO-1 promoters are 57 and 30 %, in Mel 195, and 22 and 33 % in MZ-1257 RCC cells, respectively[2].

体内研究
(In Vivo)

Guadecitabine (S110) is effective at retarding tumor growth. While the tumors do not shrink in size with Guadecitabine treatment, they experience very minimal growth while the tumors treated with PBS only show substantial growth. In addition, Guadecitabine induces much less toxicity as determined by mouse weight changes when given subcutaneously (SQ) compare to that with IP injections[3].

Cell Assay
[2]

Cells (3 to 4×105) are seeded in a T75 tissue culture flask and treated 24 h later with Guadecitabine , by replacing the medium with fresh one containing 1 μM or 10 μM of Guadecitabine, every 12 h for 2 days (4 pulses) and then with fresh medium without drugs for additional 2 days. Control cultures are treated under similar experimental conditions in the absence of drug[2].

Animal Administration
[3]

Athymic nu/nu mice are inoculated subcutaneously (SQ) in the right hind flank with 107 EJ6 bladder cancer cells. After tumors reach 0.5 cm in diameter, animals are stratified into three groups with eight animals per group to begin treatments. Doses and dosing schedules are designed so that each group receives molar equivalents of Guadecitabine (S110). The agent is administered SQ once weekly at a dose of 12.2 mg/kg for Guadecitabine for three weeks. The study includes an appropriate PBS control group. Tumor sizes by caliper and body weight measurements are taken twice weekly to monitor tumor growth inhibition and tolerability[3].

生物活性

SGI-1776 is an inhibitor of Pim kinases, with IC50s of 7 nM, 363 nM, and 69 nM for Pim-1, -2 and -3, respectively.

IC50 & Target

Ki: 7 nM (Pim-1), 363 nM (Pim-2), 69 nM (Pim-3)[4]
体外研究
(In Vitro)

SGI-1776 (2.5, 5 μM) inhibits Pim-1 protein expression and Pim-1 kinase activity in SACC cells. SGI-1776 (2.5, 5 μM) causes cell cycle arrest and reduces cell proliferation in SACC-83 and SACC-LM cells. SGI-1776 (5 μM) inhibits cell migration and invasiveness in both SACC-83 and SACC-LM cells. SGI-1776 (0, 2.5, or 5 μM) induces apoptosis via Caspase-3 activation[1]. SGI-1776 (5 µM) exerts inhibitory effects on both lipid accumulation and TG synthesis without affecting the number of adipocytes. SGI-1776 (5 µM) inhibits adipogenesis particularly at an early phase of differentiation. SGI-1776 (5 µM) decreases the expression of C/EBP-α and PPAR-γ and the phosphorylation levels of STAT-3 during adipocyte differentiation, and downregulates the protein and/or mRNA expression of FAS, leptin and RANTES during adipocyte differentiation[2]. SGI-1776 shows the significant activity against HO-8910 cells in a dose-dependent manner, with IC50 of (5.2±0.6) µM, and the inhibiting effect of SGI-1776 is sharply increased from 1.25 µM to 20 µM in vitro. SGI-1776 inhibits the migration and invasion of HO-8910 cells in a dose-dependent manner, and the inhibiting migration and invasion rate of 5 µM. SGI-1776 (2.5, 5 and 10 µM) decreases Pim-1 kinase activity of HO-8910 cells in a dose-dependent manner. Furthermore, the down-regulation of Pim-1 expression by SGI-1776 significantly inhibits cell viability, arrests cell in G1 phase, and inhibits the migration and invasion[3].

Kinase Assay
[1]

SACC-83 and SACC-LM cells of 0 μM, 2.5 μM and 5 μM groups after SGI-1776 exposure are harvested. 6 samples of SACC cells are diluted in Kinase buffer and pipetted into the wells which is pre-coated with a substrate corresponding to recombinant p21waf1. It contains threonine residues that can be efficiently phosphorylated by Pim-1. After undergoing the procedure, measure absorbance in each well is quantitated by spectrophotometry at dual wavelengths of 450/540 nm. It reflects the relative amount of Pim-1 activity in the 6 groups of SACC cells.

Cell Assay
[3]

Cells are seeded in a 96-well plate at a density of 5 000 cells/well. After incubation for 24 h, different concentrations of SGI-1776 (0.625, 1.25, 2.5, 5, 10, 20, 40 µM) are added to each well and cultured for 48 h. The medium is removed and then incubated with 5 mg/L MTT for 4 h. Next, the supernatant is removed after centrifugation. Finally, 100 µL of DMSO is added and an absorbance at 570 nm wavelength (A570) is measured by enzyme-labeling instrument. Relative cell proliferation inhibition rate (IR)=(1-average A570 of the experimental group/average A570 of the control group)×100%.

Animal Administration
[4]

The conditions for animal room environment and photoperiod are 20-25°C, 40%-70% humidity, and 12 hours of light/12 hours of dark cycle. Each mouse is inoculated subcutaneously at the right flank with MV-4-11 tumor cells (5×106). The treatments start when the tumor size reach 80-150 mm3. Mice are randomized to treatment groups based on their tumor sizes; tumor size is measured in 2 dimensions using a caliper, and the volume is expressed in mm3 using the formula: V = 0.5 a × b2 where a and b are the long and short diameters of the tumor, respectively. Pretreatment randomization ensures that each group has approximately the same mean tumor size. Mice are treated with vehicle (5% dextrose), SGI-1776 or cytarabine (ara-C). SGI-1776 and ara-C are formulated in 5% dextrose. SGI-1776 is administered by oral gavage (PO) on a daily × 5/week or twice/week schedule; ara-C is administered by intraperitoneal injection 3 times/week for 3 consecutive weeks. Animals are euthanized when their measured tumor size is greater than 3000 mm3 or when they lose ≥ 20% initial body weight; if the body weight loss ≥ 15%, treatment is stopped at first until mice regain body weight. Mice are euthanized when body weight loss is still ≥ 20% even after stopping treatment. T/C value (in %) is an indication of antitumor efficacy, where T and C are the mean tumor volume of the treated and control groups, respectively, on a given day. The differences between the mean tumor sizes for comparing groups is analyzed using the ANOVA test, where P ≤ 0.05 is considered to be statistically significant.

Kinase Assay
[1]

To determine the nature of inhibition of DNMTase activity by SGI-1027, DNMT1 enzyme activity is measured in presence of a fixed concentration of SGI-1027 (0, 2.5, 5, and 10 μM) while one of the two (Ado-Met or DNA) is varied in a particular reaction mixture. At a fixed concentration of DNA (500 ng) varying concentrations of Ado-Met used are from 25-500 nM, respectively. Similarly, final DNA concentrations are varied from (25-500 ng) at 75 nM Ado-Met[1].

Cell Assay
[1]

Rat hepatoma H4IIE cells are grown in DMEM supplemented with fetal bovine serum (10%) and calf serum (10%). Cells are seeded into 96-well plates and after 48 h exposed to SGI-1027 at concentrations ranging from 0 to 300 µM. The solubility is determined by Nephalometry techniques immediately after dosing and before harvesting the cells at 24 h. Following the exposure period, the cells or their supernatant (culture medium) are analyzed for changes in cell proliferation (propidium iodide), membrane leakage (α-GST), mitochondrial function [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and cellular ATP], oxidative stress (intracellular GSH and 8-isoprostane), and apoptosis (caspase-3). The half-maximal toxic concentration (TC50) is determined from the dose-response curves[1].
