Copper nanoparticles (CuNPs) catalyzed chemoselective reduction of nitroarenes in aqueous medium

Abstract: A procedure for practical synthesis of CuNPs from CuSO4·5H2O is established, under appropriate reaction conditions, using rice (Oryza sativa) as an economic source of reducing as well as a stabilizing agent. Optical and microscopic techniques are employed for the characterization of the synthesized CuNPs and the sizes of the particles were found to be in the range of 8 ± 2 nm. The nanoparticles are used as a catalyst for chemoselective reduction of aromatic nitro compounds to corresponding amines under ambient conditions and water as a reaction medium. Graphic abstract: CuNPs are synthesized using hydrolysed rice and used as catalyst for chemoselective reduction of nitroarenes to their corresponding amines in water.

Cu(II)-Mediated N-H and N-Alkyl Aryl Amination and Olefin Aziridination

Cu(II)-mediated direct NH2 and NH alkyl aryl aminations and olefin aziridinations are described. These room-temperature, one-pot, environmentally friendly procedures replace costly Rh2 catalysts and, in some instances, display important differences with comparable Rh2- and Fe-supported reactions.

Pyrrolidinyl phenylurea derivatives as novel CCR3 antagonists

Optimization starting with our lead compound 1 (IC50 = 4.9 nM) led to the identification of pyrrolidinyl phenylurea derivatives. Further modification toward improvement of the bioavailability provided (R)-1-(1-((6-fluoronaphthalen-2-yl)methyl)pyrrolidin-3-yl)-3-(2-(2- hydroxyethoxy)phenyl)urea 32 (IC50 = 1.7 nM), a potent and orally active CCR3 antagonist.

Synthesis and characterization of selected 4,4′-diaminoalkoxyazobenzenes

The role of the -N(CH2CH2OH)2 group in producing a mutagenic response from 4-((3-(2-hydroxyethoxy)4-amino)phenylazo)-N,N-bis(2-hydroxyethyl)aniline has been investigated. To accomplish this goal, a group of substituted 4,4′-diaminoazobenzene dyes was synthesized, and their structures were confirmed using 1H NMR, TOF-LC-ESI mass spectrometry, and combustion analysis. Mutagenicity was determined using the standard Ames test in Salmonella strains TA98, TA100, and TA1538 with and without S9 enzyme activation. The results of this study provide evidence that the mutagenicity of the parent dye arises from the metabolic cleavage of N-hydroxyethyl groups to give the corresponding -NHCH2CH2OH and -NH2 substituted monoazo dyes as direct-acting mutagens. All 5 of the dyes studied were mutagenic at various levels with and without S9 enzyme activation in TA1538. In addition, the results show that removing one N-hydroxyethyl group and capping both -OH groups in the parent dye did not affect mutagenicity, whereas removing both N-hydroxyethyl groups produced a strong direct-acting mutagen in all three bacterial strains. Increasing the length of the N-alkyl chain from two to three carbon atoms eliminated mutagenicity in TA98 without S9 activation.
