2-cyclohexylamino-5,8-dimethoxy-1,4-naphthoquinone inhibits LPS-induced BV2 microglial activation through MAPK/NF-kB signaling pathways
AIMS To verify the effects of several 5,8-dimethoxy-1,4-naphthoquinone (DMNQ) derivatives on LPS-induced NO production, cellular ROS levels and cytokine expression in BV-2 microglial cells. MAIN METHODS An MTT assay and FACS flow cytometry were performed to assess the cellular viability and apoptosis and cellular ROS levels, respectively. To examine the expression of pro-inflammatory cytokine...
متن کامل2-Chloro-3-(4-chlorobenzamido)-1,4-naphthoquinone
The naphthoquinone ring is almost perpendicular [dihedral angle 71.02 (3)°] to the phenyl group of the title compound, C(17)H(9)Cl(2)NO(3), while the dihedral angle between the amide group and the 4-chloro-phenyl ring is 21.9 (2)°. The conformation of the N-H and C=O bonds are anti to each other. N-H⋯Cl hydrogen bonds link the mol-ecules into chains in the a-axis direction. In addition, these c...
متن کاملN-[2-(Cyclohexylamino)-2-oxoethyl]-N-(4-octyloxy) phenyl-prop-2-enamide
N-[2-(Cyclohexylamino)-2-oxoethyl]-N-(4-octyloxy)phenyl-prop-2-enamide was prepared in good yield by coupling of 4(octyloxy)aniline, Cyclohexyl isocyanide, paraformaldehyde and acrylic acid by multicomponent Ugi reaction, at room temperature. The structure of the newly synthesized tripeptoid derivative was well characterized using elemental analysis, FTIR, NMR and mass spectral data.
متن کاملStudies on the photochemistry of 2-methyl-1,4-naphthoquinone.
It has been known since the isolation of the vitamins K that derivatives of 2-methyl-1,4-naphthoquinone (MN&) are unstable to light (l-5). However, the exact nature of the chemical change is still under discussion (6, 7). An interesting observation by MacCorquodale and coworkers (3) that the vitamin is quite stable as it exists in crude extracts, only becoming labile after a fair degree of puri...
متن کاملMolluscicidal activity of 2-hydroxy-[1,4]naphthoquinone and derivatives.
The toxic profile of lawsone (2-hydroxy-[1,4]naphthoquinone) and a series of [1,4]naphthoquinone derivatives was evaluated against the brine shrimp Artemia salina and against the mollusk Biomphalaria glabrata, the main transmitting vector of schistosomiasis in Brazil. Of the seventeen compounds tested nine fell below the threshold of 100 microg/mL set for potential molluscicidal activity by the...
