Background on AH 7614

Target: FFA4/GPR120

IC50: N/A

AH7614 is a selective and potent free fatty acid receptor 4 (FFA4/GPR120) antagonist with pIC50 values of 7.1, 8.1 and 8.1 at the human, mouse and rat receptor, respectively [1]. The free fatty acid receptor 4 (FFA4/GPR120), a member of the G protein-coupled receptor family, is a potential 7TM receptor involved in long-chain fatty acid-stimulated glucagon-like peptide-1 (GLP-1) secretion. FFA4 is highly expressed in the intestinal endocrine cell line STC-1 and the intestine. GLP-1 regulates multiple physiological functions including eating behavior [2].

In vitro: AH7614 (0.063, 0.25, and 1μM) blocked linoleic acid and GSK137647A-induced intracellular calcium increase in U2OS osteosarcoma cells expressing the FFA4 receptor [1]. In addition, the increase of glucose-stimulated insulin secretion by GSK137647A (50 μM) was abolished in the presence of the selective FFA4 antagonist AH7614 (100 μM) in the MIN6 mouse insulinoma cell line. Moreover, AH7614 (100 μM) blocked GSK137647A (100μM)-mediated a modest increase of GLP-1 secretion in the NCIH716 cells [1].

Cyp1b1-mediated suppression of lymphoid progenitors in bone marrow by polycyclic aromatic hydrocarbons coordinately impacts spleen and thymus: a selective role for the Ah Receptor.[Pubmed:28116098]

Pharmacol Res Perspect. 2016 Jul 29;4(4):e00245.

Bone marrow (BM) hematopoietic stem cells differentiate to common lymphoid progenitors (CLP) that emigrate to the thymus to form T cells or differentiate into immature B cells that then migrate to the spleen for maturation. Rapid in vivo suppression of BM progenitor cells by a single oral or intraperitoneal dose of 7,12-dimethylbenz(a)anthracene (DMBA) subsequently decreased mature lymphoid populations in BM, spleen, and thymus. These suppressions depended on BM CYP1B1, but not on aryl hydrocarbon receptor (AhR) activity. Suppression of pre-B colony formation at 6 h, correlated with subsequent decreases in mature BM, spleen, and thymus populations (48-168 h). Thymus T-cell ratios were unaffected, suggesting low local toxicity. DMBA treatment suppressed progenitor cells 24-h post treatment in wild type (WT), AhRb mice, but not in Cyp1b1-ko mice. The stem cell populations were sustained. Benzo(a)pyrene (BP) mediated a similar progenitor suppression up to 6 h, but reversal rapidly ensued. This recovery was absent in mice with a polycyclic aromatic hydrocarbon (PAH)-resistant, AhRd genotype. This AhR-dependent progenitor recovery with BP induction accounts for the absence of suppression of B220+ BM and spleen populations at 48-168 h. However, DMBA and BP produced similar profiles for thymus cell suppression, independent of AhR genotype. Thus, lymphoid progenitors may exit the BM to the thymus prior to the BP reversal. This progenitor recovery is associated with elevated chemokines and cytokines that depend on AhR-mediated induction of CYP1A1. This response increased constitutively in Cyp1b1-ko BM, demonstrating that CYP1B1 metabolizes local stimulants that impact a basal progenitor protection process.

Post space preparation timing of root canals sealed with AH Plus sealer.[Pubmed:28194361]

Restor Dent Endod. 2017 Feb;42(1):27-33.

OBJECTIVES: To determine the optimal timing for post space preparation of root canals sealed with epoxy resin-based AH Plus sealer in terms of its polymerization and influence on apical leakage. MATERIALS AND METHODS: The epoxy polymerization of AH Plus (Dentsply DeTrey) as a function of time after mixing (8, 24, and 72 hours, and 1 week) was evaluated using Fourier transform infrared (FTIR) spectroscopy and microhardness measurements. The change in the glass transition temperature (Tg ) of the material with time was also investigated using differential scanning calorimetry (DSC). Fifty extracted human single-rooted premolars were filled with gutta-percha and AH Plus, and randomly separated into five groups (n = 10) based on post space preparation timing (immediately after root canal obturation and 8, 24, and 72 hours, and 1 week after root canal obturation). The extent of apical leakage (mm) of the five groups was compared using a dye leakage test. Each dataset was statistically analyzed by one-way analysis of variance and Tukey's post hoc test (alpha = 0.05). RESULTS: Continuous epoxy polymerization of the material with time was observed. Although the Tg values of the material gradually increased with time, the specimens presented no clear Tg value at 1 week after mixing. When the post space was prepared 1 week after root canal obturation, the leakage was significantly higher than in the other groups (p < 0.05), among which there was no significant difference in leakage. CONCLUSIONS: Poor apical seal was detected when post space preparation was delayed until 1 week after root canal obturation.

Retreatability of two endodontic sealers, EndoSequence BC Sealer and AH Plus: a micro-computed tomographic comparison.[Pubmed:28194360]

Restor Dent Endod. 2017 Feb;42(1):19-26.

OBJECTIVES: Recently, bioceramic sealers like EndoSequence BC Sealer (BC Sealer) have been introduced and are being used in endodontic practice. However, this sealer has limited research related to its retreatability. Hence, the aim of this study was to evaluate the retreatability of two sealers, BC Sealer as compared with AH Plus using micro-computed tomographic (micro-CT) analysis. MATERIALS AND METHODS: Fifty-six extracted human maxillary incisors were instrumented and randomly divided into 4 groups of 14 teeth: 1A, gutta-percha, AH Plus retreated with chloroform; 1B, gutta-percha, AH Plus retreated without chloroform; 2A, gutta-percha, EndoSequence BC Sealer retreated with chloroform; 2B, gutta-percha, EndoSequence BC Sealer retreated without chloroform. Micro-CT scans were taken before and after obturation and retreatment and analyzed for the volume of residual material. The specimens were longitudinally sectioned and digitized images were taken with the dental operating microscope. Data was analyzed using an ANOVA and a post-hoc Tukey test. Fisher exact tests were performed to analyze the ability to regain patency. RESULTS: There was significantly less residual root canal filling material in the AH Plus groups retreated with chloroform as compared to the others. The BC Sealer samples retreated with chloroform had better results than those retreated without chloroform. Furthermore, patency could be re-established in only 14% of teeth in the BC Sealer without chloroform group. CONCLUSION: The results of this study demonstrate that the BC Sealer group had significantly more residual filling material than the AH Plus group regardless of whether or not both sealers were retreated with chloroform.

Cytotoxicity of GuttaFlow Bioseal, GuttaFlow2, MTA Fillapex, and AH Plus on Human Periodontal Ligament Stem Cells.[Pubmed:28343929]

J Endod. 2017 May;43(5):816-822.

INTRODUCTION: The aim of the present study was to evaluate the in vitro cytotoxicity of endodontic sealers (GuttaFlow Bioseal, GuttaFlow2, and MTA Fillapex) on human periodontal ligament stem cells (hPDLSCs). As a reference, AH Plus was compared with the more recent endodontic sealers regarding cell viability and cell attachment. METHODS: Biological testing was carried out in vitro on hPDLSCs. Cell viability assay was performed by using eluates from each endodontic sealer. To assess cell morphology and attachment to the different sealers, the hPDLSCs were directly seeded onto the material surfaces and analyzed by scanning electron microscopy. Chemical composition of the sealers was determined by energy-dispersive x-ray, and eluates were analyzed by inductively coupled plasma mass spectrometry. Statistical differences were assessed by analysis of variance and Tukey test (P < .05). RESULTS: Cell viability was evident after 24 hours in the presence of GuttaFlow Bioseal and GuttaFlow 2 but not in the case of AH Plus or MTA Fillapex. At 168 hours, GuttaFlow Bioseal and GuttaFlow 2 exhibited high and moderate cell viability, respectively, whereas AH Plus and MTA Fillapex revealed low rates of cell cell viability (P < .001). Finally, scanning electron microscopy studies revealed a high degree of proliferation, cell spreading, and attachment, especially when using GuttaFlow Bioseal disks. CONCLUSIONS: GuttaFlow Bioseal and GuttaFlow2 showed lower cytotoxicity than MTA Fillapex and AH plus. Further in vitro and in vivo investigations are required to confirm the suitability of GuttaFlow Bioseal for clinical application.
