AMG 925 HCl is a potent, selective, and orally available FLT3/CDK4 dual inhibitor with IC50s of 2±1 nM and 3±1 nM, respectively.
IC50 & Target[1]
FLT3
2 nM (IC50)
CDK4

CDK6
8 nM (IC50)
CDK2
375 nM (IC50)
CDK1

体外研究 (In Vitro)
AMG 925 also inhibits CDK6, CDK2, and CDK1 in kinase assays with IC50s of 8±2 nM, 375±150 nM, 1.90±0.51 μM, respectively. A fair overall kinase selectivity of AMG 925 is as determined by KinomScan against a panel of 442 various kinases. Cellular selectivity (on-target vs. off-target activity) of AMG 925 is about 50-fold as evaluated by comparison of its growth-inhibiting activity in RB-positive (RB+) and RB-negative (RB–) non- acute myeloid leukemia (AML) cancer cell lines. AMG 925 potently inhibits growth of AML cell lines MOLM13 (FLT3-ITD; IC50=19 μM) and Mv4-11 (FLT3-ITD; IC50=18 μM)[1].

体内研究 (In Vivo)
MOLM13 tumor-bearing mice are dosed twice daily by oral administration 6 hours apart with 12.5, 25, or 37.5 mg/kg AMG 925. Tumors are then harvested 3, 9, 12, and 24 hours after the first dose, and analyzed for levels of P-STAT5 and P-RB. Maximum inhibition of P-STAT5 and P-RB is achieved at 6 and 12 hours respectively at the 37.5 mg/kg dose of AMG 925. Interestingly, a rebound of P-STAT5 at 24 hours is observed, possibly as a result of compensational feedback. The pharmacodynamic responses of P-STAT5 and P-RB inhibition correlated with plasma concentrations of AMG 925. AMG 925 inhibits AML xenograft tumor growth by 96% to 99% without significant body weight loss. The antitumor activity of AMG 925 correlates with the inhibition of STAT5 and retinoblastoma protein (RB) phosphorylation, the pharmacodynamic markers for inhibition of FLT3 and CDK4, respectively. In addition, AMG 925 is also found to inhibit FLT3 mutants (e.g., D835Y) that are resistant to the current FLT3 inhibitors (e.g., AC220 and Sorafenib)[1].

Cell Assay [1]
MOLM13 and Mv4-11 are used. MOLM13-Luc cells are constructed by transduction of MOLM13 cells with the pLV218G luciferin/lentivector, which expresses luciferase under the murine EF1α promoter. Sorafenib-resistant MOLM13 (MOLM13sr) and Mv4-11 (Mv4-11sr) are isolated by passaging the cells in growth medium containing increasing concentrations of Sorafenib (1-1 nM). Cell growth is measured by a DNA synthesis assay. Cells are seeded in a 96-well Cytostar T plate at a density of 5×103 cells/well in a total volume of 160 μL. Test compounds (e.g., AMG 925; 0.03 and 0.3μM) are serially diluted into the plate (20 μL/well) and 20 μL/0.1 μCi of [14C]-Thymidine added to each well. Isotope incorporation is determined using a β plate counter after further 72-hour incubation. Apoptosis is assayed by using the Vybrant Apoptosis Assay Kit. Briefly, cells are seeded into a 6-well plate at 5×105 cells per well and treated with compounds (e.g., AMG 925; 0.003, 0.01, 0.03, 0.1, 0.3, and 1 μM) for 24 hours. The cells are then stained with reagents provided in the kit and analyzed by flow cytometry. The Sytox Green fluorescence versus allophycocyanin fluorescence dot plot shows resolution of live, apoptotic, and dead cells, which are quantified using the Flowjo software. The cell-cycle analysis is done by treating the cells with AMG 925 for 24 hours followed by using the CycleTest Kit. Ten thousand events are acquired and the proportions of cells in each cycle phase are calculated using the ModFit software[1].

This material is bacteriostatic against actively growing TB bacilli. Mycolic acids attach to the 5′-hydroxyl groups of D-arabinose residues of arabinogalactan and form mycolyl-arabinogalactan-peptidoglycan complex in the cell wall. This material disrupts arabinogalactan synthesis by inhibiting arabinosyltransferases, specifically those in Mycobacterium, interfering with the biosynthesis of arabinogalactans found in the cell wall of mycobacteria and leading to increased cell wall permeability.Antibacterial agent. Selective Mycobacterium arabinosyltransferase inhibitor. Inhibits arabinogalactan synthesis in the cell wall leading to increased permeability. Shows bacteriostatic effects against TB bacilli in vivo. Orally active.

Tubastatin A (Hydrochloride) is a potent and selective HDAC6 inhibitor with IC50 of 15 nM in a cell-free assay, and is selective (1000-fold more) against all other isozymes except HDAC8 (57-fold more).

体外研究 (In Vitro)
Tubastatin A is substantially selective for all 11 HDAC isoforms and maintains over 1000-fold selectivity against all isoforms excluding HDAC8, where it has approximately 57-fold selectivity. In homocysteic acid (HCA) induced neurodegeneration assays, Tubastatin A displays dose-dependent protection against HCA-induced neuronal cell death starting at 5 μM with near complete protection at 10 μM[1]. At 100 ng/mL Tubastatin A increases Foxp3+ T-regulatory cells (Tregs) suppression of T cell proliferation in vitro[2]. Tubastatin A treatment in CC12 cells would lead to myotube formation impairment when alpha-tubulin is hyperacetylated early in the myogenic process; however, myotube elongation occurs when alpha-tubulin is hyeperacetylated in myotubes[3]. A recent study indicates that Tubastatin A treatment increases cell elasticity as revealed by atomic force microscopy (AFM) tests without exerting drastic changes to the actin microfilament or microtubule networks in mouse ovarian cancer cell lines, MOSE-E and MOSE-L[4].

Kinase Assay [1]
Enzyme inhibition assays are performed using the Reaction Biology HDAC Spectrum platform. The HDAC1, 2, 4, 5, 6, 7, 8, 9, 10, and 11 assays use isolated recombinant human protein; HDAC3/NcoR2 complex is used for the HDAC3 assay. Substrate for HDAC1, 2, 3, 6, 10, and 11 assays is a fluorogenic peptide from p53 residues 379-382 (RHKKAc); substrate for HDAC8 is fluorogenic diacyl peptide based on residues 379-382 of p53 (RHKAcKAc). Acetyl-Lys (trifluoroacetyl)-AMC substrate is used for HDAC4, 5, 7, and 9 assays. Tubastatin A is dissolved in DMSO and tested in 10-dose IC50 mode with 3-fold serial dilution starting at 30 μM. Control Compound Trichostatin A (TSA) is tested in a 10-dose IC50 with 3-fold serial dilution starting at 5 μM. IC50 values are extracted by curve-fitting the dose/response slopes.

Cell Assay [1]
Primary cortical neuron cultures are obtained from the cerebral cortex of fetal Sprague-Dawley rats (embryonic day 17). All experiments are initiated 24 hours after plating. Under these conditions, the cells are not susceptible to glutamate-mediated excitotoxicity. For cytotoxicity studies, cells are rinsed with warm PBS and then placed in minimum essential medium containing 5.5 g/L glucose, 10% fetal calf serum, 2 mM L-glutamine, and 100 μM cystine. Oxidative stress is induced by the addition of the glutamate analogue homocysteate (HCA; 5 mM) to the media. HCA is diluted from 100-fold concentrated solutions that are adjusted to pH 7.5. In combination with HCA, neurons are treated with Tubastatin A at the indicated concentrations. Viability is assessed after 24 hours by MTT assay (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) method.

Animal Administration [2]
The effects of HDAC6 targeting in dextran sodium sulfate (DSS) and adoptive transfer models of colitis are evaluated, using 10 mice per group. Freshly prepared 4% (wt/vol) DSS is added daily for 5 days to the pH-balanced tap water of WT B6 mice. Mice are treated daily for 7 days with tubacin or niltubacin (0.5 mg/kg of body weight/day, i.p.), and colitis is assessed by daily monitoring of body weight, stool consistency, and fecal blood. Stool consistency is scored as 0 (hard), 2 (soft), or 4 (diarrhea), and fecal blood (Hemoccult) is scored as 0 (absent), 2 (occult), or 4 (gross). To assess prevention of colitis in a T cell-dependent model, CD4+ CD45RBhi T cells (1×106) isolated from WT mice using magnetic beads (>95% cell purity, flow cytometry) are injected i.p. into B6/Rag1−/− mice plus CD4+ CD25+ Tregs (1.25×105) isolated using magnetic beads from HDAC6−/− or WT mice (>90% Treg purity, flow cytometry) and mice are monitored biweekly for clinical evidence of colitis. To assess therapy of established T cell-dependent colitis, B6/Rag1−/− mice are injected i.p. with CD4+ CD45RBhi cells (1×106). Once colitis has developed, mice also receive CD4+ CD25+ Tregs (5×105 cells) isolated as described above from HDAC6−/− or WT mice or treatment with HDAC6i (tubastatin A) or HSP90i (17-AAG). Mice are monitored for continued weight loss and stool consistency. At the cessation of the study, paraffin sections of colons stained with Alcian Blue or hematoxylin and eosin are graded histologically or evaluated by immunoperoxidase staining for Foxp3+ Treg infiltration.
