Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis. name: 1,1′-Ferrocenedicarboxaldehyde, Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a reaction from occurring. In a patent，Which mentioned a new discovery about 1271-48-3
The new family of Ruthenium(II)-arene complexes of lidocaine of formula [RuII(eta6-p-cymene)Cl(LC)](PF6), 1, [RuII(eta6-p-cymene) (C[tbnd]CFc) (LC)](PF6), 2, [RuII(eta6-p-cymene) (C[tbnd]CFcIP) (LC)](PF6), 3 (LC: lidocaine, FcC[tbnd]CH: ferrocenyl acetylene, C[tbnd]CFcIP: 1?-(phenanthro[9,10-d]imidazole) ferrocenyl-1-acetylene) were prepared and characterized by ESI-MS spectrometry, elemental analysis, IR,1H and13C NMR spectroscopy. The photocytotoxicity of 1?3 was studied with visible light (400?700 nm) against a panel of human cancer cell lines namely, A-375 (human melanoma), HeLa (human cervical cancer) and MCF-7 (human breast cancer) cancer cells. The photoactivity follows the order 1 < 2 < 3 with 2 and 3 having IC50values in A-375 (melanoma) cells in the low micromolar range. These complexes interact with calf thymus DNA. The photocleaving pUC19 DNA of complexes with visible light (400?700 nm) was studied and the results exhibited the active involvement of superoxide and hydroxyl radicals as the reactive oxygen species (ROS) in the DNA photocleavage reactions. These complexes interact with calf thymus DNA via intercalative mode that binding constants vary in the order: 3 > 2 > 1. The complexes 2 and 3 were photoactivated in A-375 cells by visible radiation and analyzed by alkaline single-cell gel electrophoresis.
If you are interested in 1271-48-3, you can contact me at any time and look forward to more communication. The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. name: 1,1′-Ferrocenedicarboxaldehyde
