Chemistry is traditionally divided into organic and inorganic chemistry. name: 6-Nitroindolin-2-one. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 474799-41-2

With antibiotics resistance developing rapidly, new antibacterial agents are needed to be discovered. We readily synthesized 11 indolin-2-one compounds and found a hybrid of indolin-2-one and nitroimidazole 3-((1-methyl-5-nitro-1H-imidazol-2-yl)methylene)indolin-2-one to be effective on Staphylococcus aureus strains. Six derivatives of this compound were further designed and synthesized in order to enhance its efficacy. After a second turn of structural refinement, a novel hybrid of indolin-2-one and nitroimidazole 3-((1-methyl-5-nitro-1H-imidazol-2-yl)methylene)-5-nitroindolin-2-one with a nitro group on C-5 position of indolin-2-one was shown to exhibit remarkable antibacterial activities with a low MIC value against MRSA ATCC 33591. Besides, this molecule demonstrated its potency on Gram-negative bacteria and VRE strain. The time-killing curve experiment showed its good bactericidal activity. Low hemolytic rate suggested its promising safety profile.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: 6-Nitroindolin-2-one, you can also check out more blogs about474799-41-2

474799-41-2, 6-Nitroindolin-2-one is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,474799-41-2

Triethylamine (3.91 rnL, 28.0 mmol) and Z4 (1.0 g, 5.61 mmol) are added successively to furan-2-carboxylic acid (1.32 g, 11.79 mmol) and TBTU (3.79 g, 11.79 mmol) in anhydrous DMF (5 mL) and the mixture is stirred for 24 h at RT. The reaction mixture is in poured into 1 N HCl: MeOH = 1 : 1, the precipitate is suction filtered and digested with iPrOH. Yield: 1.60 g (78 percent).Alternatively CH2Cl2 may be used as solvent. If no crystalline product is obtained, the reaction mixture is worked up by extraction and the residue is optionally chromatographed.

474799-41-2 6-Nitroindolin-2-one 17960994, aindole-building-block compound, is more and more widely used in various fields.
