treatment of acetyl- 1,4-benzoquinone with isoprene gave the corresponding regioselective adduct (i). rearrangement of the adduct (1) in pyridine and methanol gave 2-acetyl-5, 8-dihydro-6-methyl- 1,4-dihydroxynaphthalene (2). silver oxide oxidation of the rearranged product (2) gave 2-acetyl-5,8-dihydro- 6-methyl- 1,4naphthalenedione (3). regioselective addition of trans-piperylene to this comp...
Abstract We report a series of ( Z )-2-acetyl-4-benzyliden-1-methyl-1 Н -imidazol-5(4 )-ones with pronounced solvent-dependent intensity fluorescence variation. The introduction the 2-acetyl group allows one to shift absorption and emission maxima long-wavelength region. have shown that these compounds can be used for staining endoplasmic reticulum fluorescent microscopy.
N-Acetylation of (2,3,4,6-tetra-O-acetyl-a-D-glucopyranosyl) (2,3,4,6-tetra-0-acetyl-/?-D-glucopyranosyl)amine or bis(2,3,4,6-tetra-0-acetyl-/3-D-glucopyranosyl)amine afforded N-acetyl-bis(2,3, 4,6-tetra-0-acetyl-/3-D-glucopyranosyl)amine; deacetylation of the latter gave Af-acetyl-di-/3-Dglucopyranosylamine. Similarly, TV-acetylation of bis(2,3,4-tri-0-acetyl-/3-L-rhamnopyranosyl)amine led to ...
Background: The brain in exposure to irritating factors may lead to production of some chemical factors and proinflammatory cytokines and neuroinflammation. Over time, the chronic neuroinflammation will cause some cognitive disorders and neurodegenerative diseases. The present study studied the effect of acetyl L -carnitine on cognitive and cellular disorders derived from lipopolysaccharide (LP...
Background and Objective: Contusion injury causes a major variety of functional and sensory disorders. In this research, we tried to study histological changes after performing contusion model in spinal cord. For this reason, we investigated the effect of acetyl L-carnitine on gliosis reaction by using immunohistochemistry method for GFAP and CNPase after spinal cord injury(SCI). Materials ...
