Seven FDA-certified food dyes were investigated as organocatalysts. As a result, Fast Green FCF and Brilliant Blue FCF were discovered as catalysts for the chlorination of a wide range of arenes and heteroarenes in moderate to excellent yields and high regioselectivity. Mechanistic investigations of the sep. systems indicated that different modes of activation are in operation, with Fast Green FCF being a light-promoted photoredox catalyst that was facilitating a one-electron oxidation of N-chlorosuccinimide (NCS) and Brilliant Blue FCF serving as a chlorine-transfer catalyst in its sulfonphthalein form with 1,3-dichloro-5,5-dimethylhydantoin (DCDMH) as stoichiometric chlorine source. Dearomatization of naphthol and indole substrates was observed in some examples using the Brilliant Blue/DCDMH system.

Takeshita, Kenji; Ogawa, Hiroaki I.; Maeda, Toshinari published the artcile< Structural chromosome aberrations cause swelling of the nucleus>, HPLC of Formula: 6055-19-2, the main research area is clastogen chromosomal aberration nuclear swelling; Aneugen; Carcinogen; Chromosomal aberration; Clastogen; Genotoxicity; Non-mutagen; Nuclear swelling.

Background: Carcinogens are known to cause swelling of the mammalian cell nucleus. However, the mechanism of the swelling and its toxicol. significance have not been fully elucidated. Since nuclear swelling (NS hereafter) has been frequently observed in chromosomal aberration (CA hereafter) tests (in vitro), the relationship between NS and CAs was investigated in this study. Results: In a short-term CA test using the fibroblast CHL cell line, the appearance of NS increased in a dose-dependent manner after exposure to six types of clastogens (mitomycin C, Me methane sulfonate, 1-methyl-3-nitro-1-nitrosoguanidine, benzo[a]pyrene, cyclophosphamide monohydrate, and 9,10-dimethyl-2-benzanthracene), and a strong correlation was found between NS (%) and CAs (%) at each dosage. Therefore, we hypothesized that clastogens cause NS in cultured mammalian cells, since the mouse lymphoma L5178Y cell line is known to have a similar sensitivity to clastogens. Thus, we measured NS for 14 compounds (clastogens) that are known to induce structural CAs, 4 aneugens, and 12 non-mutagenes. Almost all clastogens caused NS of more than 5%, which increased in a dose-dependent manner. Among the aneugens, colchicine, and diethylstilbestrol caused the same level of NS % as the clastogens, while carbendazim and trichlorfon caused a similar level of NS % as the clastogens only at higher levels of cytotoxicity. Almost all the non-mutagens caused less than 5% NS. Conclusions: These results strongly suggest that NS is mainly caused by structural aberrations in the nucleus during interphase of the cell cycle.

Fujimori, Ko; Iguchi, Yusuke; Yamashita, Yukiko; Gohda, Keigo; Teno, Naoki published the artcile< Synthesis of Novel Farnesoid X Receptor Agonists and Validation of Their Efficacy in Activating Differentiation of Mouse Bone Marrow-Derived Mesenchymal Stem Cells into Osteoblasts>, SDS of cas: 3964-57-6, the main research area is farnesoid receptor agonist mesenchymal stem cell differentiation osteoblast; FXR; agonist; bone; mesenchymal stem cells; osteoblast.

The modulators of farnesoid X receptor (FXR), a bile acid receptor, regulate various biol. processes including bile acid metabolism and are associated with the control of fatty liver and osteoporosis. Thus, the control of FXR activity and development of FXR modulators are critical not only for research, but also for clin. application. In this study, we synthesized novel FXR agonists 1-4 possessing isoxazole and N-substituted benzimidazole moieties, and compared their effects on osteoblast differentiation with the known FXR agonists, chenodeoxycholic acid and a synthetic compound GW4064. Two (3 and 4) of the four novel FXR agonists 1-4 showed high specificities for FXR. Computer-assisted modeling suggested that the binding of the FXR agonist 3 with ligand binding domain of FXR was similar to GW4064. FXR was expressed in mouse bone marrow-derived mesenchymal stem cell (MSC)-like ST2 cells (ST-2 MSCs). The FXR agonists activated the BMP-2-induced differentiation of ST-2 MSCs into osteoblasts and enhanced the expression of RUNX2. Moreover, the potency of the FXR agonist 3 was comparable to GW4064 in promoting osteoblast differentiation of ST-2 MSCs. These results indicate that FXR activation enhanced the BMP-2-induced differentiation of MSCs into osteoblasts through activating RUNX2 expression. FXR could be a potential therapeutic target for the treatment of bone diseases such as osteoporosis.

New 2-phenyl-5-(arylsulfonyl)-7,8-dihydro-6H-imidazo[1,2-b]pyridazines I [R = 4-MeC6H4, 4-F3CC6H4, 1-naphthyl, etc.] were synthesized via sulfonylation of 2-phenyl-5,6,7,8-tetrahydroimidazo[1,2-b]pyridazine using sulfonyl chlorides. The structures of these derivatives I were elucidated by 1H NMR, 13C NMR, IR and high-resolution mass spectrometry for further characterization and were further evaluated for their anticancer activities. The anticancer activities of compounds I were evaluated against five human cancer cell lines, including A-549, Hs-683, MCF-7, SK-MEL-28 and B16-F10 cell lines with 5-fluorouracil and etoposide as reference drugs. Among the tested compounds, I [R = 5-Cl-2-OMeC6H3, 4-F3CC6H4] exhibited excellent activities in the same range of the pos. controls, 5-fluorouracil and etoposide, against MCF-7 and SK-MEL-28 cancer cell lines, with IC50 values ranging from 1 to 10 μM. The mol. docking studies of compounds, I [R = 5-Cl-2-OMeC6H3, 4-F3CC6H4] showed a strong binding with some kinases, which were linked to MCF-7 and SK-MEL-28 cancer cell lines.

Todorova, Valentina K.; Kaufmann, Yihong; Klimberg, V. Suzanne published the artcile< Increased efficacy and reduced cardiotoxicity of metronomic treatment with cyclophosphamide in rat breast cancer>, Application In Synthesis of 6055-19-2, the main research area is cyclophosphamide monohydrate doxorubicin hydrochloride anticancer breast cancer cardiotoxicity.

Background/Aim: It has been reported that continuous low-dose (metronomic) administration of cytotoxic drugs may be better tolerated and may have greater antitumor effects than a single high-dose chemotherapy. The aim of this study was to examine the efficacy and cardiotoxicity of metronomic administration of two of the most commonly used anticancer agents, cyclophosphamide (CPA) and doxorubicin (DOX), on an exptl. breast cancer of rats. Materials and Methods: Breast tumors were induced in Fisher 344 female rats by implanting Mat B III cells. Rats with tumors were randomized into three groups and were treated with a total dose of 160 mg/kg CPA and a total dose of 12 mg/kg DOX, administered twice per wk for four weeks. Control rats were injected with saline according to the same schedule. Echocardiog. was performed before the start of treatment and before sacrifice, which took place two weeks after the last injection, when plasma troponin was also measured. Results: The metronomic CPA eradicated the tumors and preserved body weight and echocardiog. parameters. The metronomic DOX slowed tumor growth, but was not able to prevent DOX-induced cardiotoxicity. Conclusion: These results suggest that the success of a metronomic chemotherapy in terms of both efficacy and toxicity depends on the target, the class and the route of administration of the anticancer agent.

Previously, we showed that 1-nitro-2-phenylethene, a nitrostyrene derivative of 1-nitro-2-phenylethane, induced vasorelaxant effects in rat aorta preparations Here, we studied mechanisms underlying the vasorelaxant effects of its structural analog, trans-4-chloro-β-nitrostyrene (T4CN), in rat aortic rings. Increasing concentrations of T4CN (0.54-544.69μM) fully and similarly relaxed contractions induced by phenylephrine (PHE, 1μM) or KCl (60 mM) in endothelium-intact aortic rings with IC50 values of 66.74 [59.66-89.04] and 79.41 [39.92-158.01] μM, resp. In both electromech. and pharmacomech. couplings, the vasorelaxant effects of T4CN remained unaltered by endothelium removal, as evidenced by the IC50 values (108.35 [56.49-207.78] and 65.92 [39.72-109.40] μM, resp.). Pretreatment of endothelium-intact preparations with L-NAME, ODQ, glibenclamide, or TEA did not change the vasorelaxant effect of T4CN. Under Ca2+-free conditions, T4CN significantly reduced the phasic contractions induced by caffeine or PHE, as well as the contractions due to exogenous CaCl2 in aortic preparations stimulated with PHE (in the presence of verapamil). These results suggest that in rat aortic rings, T4CN induced vasorelaxation independently from the activation of soluble guanylate cyclase/cGMP pathway, an effect that may be related to the electrophilicity of the substituted chloro-nitrostyrene. This vasorelaxation seems to involve inhibition of both calcium influx from the extracellular milieu and calcium mobilization from intracellular stores mediated by IP3 receptors and by ryanodine-sensitive Ca2+ channels.

Zhu, Xiao-Lei; Zhang, Rui; Wu, Qiong-You; Song, Yong-Jun; Wang, Yu-Xia; Yang, Jing-Fang; Yang, Guang-Fu published the artcile< Natural product neopeltolide as a cytochrome bc1 complex inhibitor: Mechanism of action and structural modification>, Application In Synthesis of 35852-58-5, the main research area is neopeltolide cytochrome bc1 inhibitor mechanism structure modification fungicide discovery; bc1 complex; inhibitor; molecular design; natural product; neopeltolide.

The marine natural product neopeltolide was isolated from a deep-water sponge specimen of the family Neopeltidae. Neopeltolide has been proven to be a new type of inhibitor of the cytochrome bc1 complex in the mitochondrial respiration chain. However, its detailed inhibition mechanism has remained unknown. In addition, neopeltolide is difficult to synthesize because of its very complex chem. structure. In the present work, the binding mode of neopeltolide was determined for the first time by integrating mol. docking, mol. dynamics simulations, and mol. mechanics Poisson-Boltzmann surface area calculations, which showed that neopeltolide is a Qo site inhibitor of the bc1 complex. Then, according to guidance via inhibitor-protein interaction anal., structural modification was carried out with the aim to simplify the chem. structure of neopeltolide, leading to the synthesis of a series of new neopeltolide derivatives with much simpler chem. structures. The calculated binding energies (ΔGcal) of the newly synthesized analogs correlated very well (R2 = 0.90) with their exptl. binding free energies (ΔGexp), which confirmed that the computational protocol was reliable. Compound 45, bearing a di-Ph ether fragment, was successfully designed and synthesized as the most potent candidate (IC50 = 12 nM) against porcine succinate cytochrome c reductase. The mol. modeling results indicate that compound 45 formed a π-π interaction with Phe274 and two hydrogen bonds with Glu271 and His161. The present work provides a new starting point for future fungicide discovery to overcome the resistance that the existing bc1 complex inhibitors are facing.

The Siglec family of cell surface receptors have emerged as attractive targets for cell-directed therapies due to their restricted expression on immune cells, endocytic properties, and ability to modulate receptor signaling. Human Siglec-8, for instance, has been identified as a therapeutic target for the treatment of eosinophil and mast cell disorders. A promising strategy to target Siglecs involves the use of liposomal nanoparticles with a multivalent display of Siglec ligands. A key challenge for this approach is the identification of a high affinity ligand for the target Siglec. Here, we report the development of a ligand of Siglec-8 and its closest murine functional orthologue Siglec-F that is capable of targeting liposomes to cells expressing Siglec-8 or -F. A glycan microarray library of synthetic 9-N-sulfonyl sialoside analogs was screened to identify potential lead compounds The best ligand, 9-N-(2-naphthyl-sulfonyl)-Neu5Acα2-3-[6-O-sulfo]-Galβ1-4GlcNAc (6′-O-sulfo NSANeu5Ac) combined the lead 2-naphthyl sulfonyl C-9 substituent with the preferred sulfated scaffold. The ligand 6′-O-sulfo NSANeu5Ac was conjugated to lipids for display on liposomes to evaluate targeted delivery to cells. Targeted liposomes showed strong in vitro binding/uptake and selectivity to cells expressing Siglec-8 or -F and, when administered to mice, exhibit in vivo targeting to Siglec-F+ eosinophils.
