Compound: 2-Furoic hydrazide, is researched, Molecular C5H6N2O2, CAS is 3326-71-4, about ONO pincer palladium (II) complexes featuring furoylhydrazone ligands: Synthesis, characterization and catalytic activity towards Suzuki-Miyaura coupling reaction.

Four new palladium pincer complexes I (R = H, 3-OMe, 3-OEt, 5-Cl) incorporating ONO type furoylhydrazone ligands have been prepared in good yields. These palladium complexes were structurally characterized by elemental anal., IR, 1H- and 13C-NMR spectra. X-ray single crystal analyses of Pd1-Pd4 revealed that the metal center adopted a slightly distorted square planar geometry in which the hydrazone bound the metal ion via the phenolic-O, azomethine-N and imidolate-O atoms. Using these ONO pincer complexes as catalyst, excellent yields of biaryls could be obtained for coupling of arylboronic acids with aryl bromides at a low catalyst loading (0.01 mol%).

Compound: 2-Furoic hydrazide, is researched, Molecular C5H6N2O2, CAS is 3326-71-4, about A novel turn on fluorescent probe for the determination of Al3+ and Zn2+ ions and its cells applications, the main research direction is fluorescent probe aluminum zinc cell imaging; Aluminum and Zinc ion; Fluorescence sensor.Synthetic Route of C5H6N2O2.

Early detection of probes is very important for limiting toxic effects of various transition metal ions for example aluminum and zinc. Monitoring of these metal ions can be challenging via conventional methods since they are high cost instrumentations, time consuming and so on. The authors report facile preparation of a fluorescence probe containing biphenyl groups that effectively selective and superb sensitivity towards aluminum(III) and zinc(II) in neutral solutions without interference from each other and other ions. In neutral pH value, the probe FOB displayed the OFF-ON fluorescence enhancement at 464 nm and 512 nm toward aluminum(III) and zinc(II), resp. The detection limit values of FOB for Al3+ and Zn2+ in neutral solutions were 1.27 and 1.02 nM, resp. and these values were significantly lower than permitted Al3+ and Zn2+ concentrations in drinking water determined by the World Health Organization (WHO) and European Water Quality. Also, fabricated cyano-biphenyl based probe is effective for sensing for aluminum(III) and zinc(II) in living human colon cancer cells even when employed at low concentrations (1.0μM). Overall, this work allows the authors to obtain a great potential to be applied to detect Al3+ and Zn2+.

Bio-mol. interactions of these complexes were analyzed using UV and emission spectroscopic studies, which revealed that compounds interact with calf thymus DNA (CT-DNA) through intercalation and also bind strongly with BSA. This further has been confirmed by theor. studies. Anticancer nature of the compounds was evaluated with the help of MTT assay against colon cancer cells (HCT-15) and normal skin cells (L929). It is verified that the complexes showed excellent cytotoxicity to cancer cells whereas negligible toxicity towards normal cells. Antioxidant activity was checked by DPPH radical scavenging assay and found that the complexes are capable of reducing available radicals. The complexes initiated cell death via reactive oxygen species generation was determined by ROS assay.

The open chain formimidic acid Et ester is slightly more potent than hetero-annulated systems. The most active compounds were further investigated for caspase activation, Bax activation and Bcl-2 down regulation compared to doxorubicin as a standard, and indeed exhibited mainly cell cycle arrest at the Pre-G1 and G2/M phases. The transcription effects of 5a and 5b on the p53 were assessed and compared with the reference doxorubicin. The results revealed an increase of 12-19 in p53 level compared to the test cells and that p53 protein level of 5a and 5b was significantly inductive (991, and 639 pg/mL, resp.) in relation to doxorubicin (1263 pg/mL).
