Hypochlorous acid (HClO) is a typical endogenous ROS produced mainly in mitochondria, and it has strong oxidative properties. Abnormal HClO levels lead to mitochondrial dysfunction, strongly associated with various diseases. It been shown that shows traces of overexpression cells both ferroptosis hepatocellular carcinoma (HCC). Therefore, visualization during HCC important explore its physiological pathological roles. So far, there no report on the HCC. Thus, we present ratiometric...
Tetradentate Schiff base ligands H2L (H2saltmen, H2salen, H2-5-Brsalen, and H2-3,5-Brsalen), derived from the condensation of corresponding salicylaldehyde or its derivatives with 1,1,2,2-tetramethylethyldiamine 1, 2-diaminoethane, reacted Mn(III) acetate perchlorate salts sodium azide cyanate to produce five dimer complexes, [Mn(saltmen)(O2CCH3)]2.2CH3CO2H (1), [Mn(saltmen)(N3)]2 (2), [Mn(salen)(NCO)]2 (3), [Mn(3,5-Brsalen)(3,5-Brsalicylaldehyde)]2 (4), [Mn(5-Brsalen)(CH3OH)]2(ClO4)2 (5)....
Hydrazine is carcinogenic and highly toxic so that it can lead to serious environmental contamination health risks although has been extensively used as an effective propellant important reactive base in industry. Thus, the development of two-emission NIR fluorescent probes for rapid detection hydrazine with high selectivity sensitivity significance great challenge both biological sciences. Here, we report a colorimetric probe specific based on hydrazinolysis reaction under physiological...
Endogenous hydrogen peroxide in vivo is related to many diseases, including cancer, diabetes, cardiovascular disease, and neurodegenerative disorders. Although probes for detection of H2O2 have been explored, rapid response are still expected application. Here, a new probe (PAM-BN-PB) was designed based on an intramolecular charge transfer (ICT) process with three parts: phenanthroimidazole, benzonitrile, phenyl boronate. By modulation ICT PAM-BN-PB, solution systems can be detected good...
A flexible metal–organic framework (MOF) of [Zn3(btca)2(OH)2]·(guest)n (H2btca = 1,2,3-benzotriazole-5-carboxylic acid) that exhibits guest molecule-controlled dynamic gas adsorption is reported in which carbon dioxide molecules rather than N2, He, and Ar induce a structural transition with corresponding appearance additional steps the isotherms. Physical insights into behaviors compound 1 were detected by at different temperatures pressures confirmed Fourier transform infrared spectroscopy...
Ferroptosis, a recently proposed form of regulated cell death, is characterized by surge in reactive oxygen species and subsequent depletion glutathione. The mitochondria nucleoli play pivotal roles the process ferroptosis. Therefore, monitoring interactions between during ferroptosis crucial for clarifying its physiological pathological processes. In this study, we designed synthesized near-infrared fluorescence probe MINU, which exhibits excellent stability against biological ions pH...
A new complex (1) of Prussian blue analogue with the composition K0.2Mn1.4Cr(CN)6 x 6H2O was prepared and characterized structurally as well magnetically. The crystal structure 1 determined by X-ray diffraction analysis. results indicate that consists a 3D cubic lattice similar to those Mn3[Cr(CN)6]2 xH2O, Mn3[Co(CN)6]2 Cd3[Cr(CN)6]2 Cd3[Co(CN)6]2 xH2O. Magnetic measurements show is ferrimagnet T(c) = 66 K. It interesting note magnetic behavior can be substantially modulated through...
Three novel, bifunctional triazine-based ligands, namely , and containing both a TEMPO bipyridine moiety have been synthesized. These bpy/TEMPO-based molecules used as catalyst precursors for the copper-catalyzed aerobic oxidation of alcohols to aldehydes ketones, in presence tert-BuOK co-catalyst. The complexes obtained situ from ligands with copper(II) bromide 2:1 acetonitrile/water mixture, selectively catalyze primary benzylic, allylic aliphatic secondary benzylic alcohols. rate achieved...
A series of dimethylaluminum complexes (L1a-i )AlMe2 (2a-i, where HL1a-i = 2-(2'-ArNH)phenyl-4-R1-oxazoline) bearing chiral, bidentate anilido-oxazolinate ligands have been prepared and characterized. Six the complexes, in presence an alcohol cocatalyst, are shown to be active initiators for stereoselective ring-opening polymerization rac-lactide toluene solution under bulk conditions, yielding polylactides with a range tacticity from slightly isotactic moderately heterotactic. The...
It is challenging to simultaneously discriminate two or three biothiols from each other due their structural similarities as well reactions sites.
Three new complexes of the formula M(2)L(2) derived from 2-(4-quinolyl)nitronyl nitroxide (4-QNNN) and M(hfac)(2) [M = Mn(II), Co(II), Cu(II)], (4-QNNN)(2).[Mn(hfac)(2)](2) (1), (4-QNNN)(2).[Co(hfac)(2)](2).2H(2)O (2), (4-QNNN)(2).Cu(hfac)(2).Cu'(hfac)(2) (3), were synthesized characterized structurally as well magnetically.
