Modulation of a - Amino - 3 - hydroxy ~ 5 - rnethyl = 44 soxazole Propionate ( AMPA ) Receptors by a Novel Organic Nitrate Ester Samuel
Positive modulators of the excitatory amino acid receptor a-Amino-3hydroxy-5-methyl-4-isoxazole Propionate (AMPA) has been shown to enhance memory and learning tasks performed by rodents and by human subjects. A new class of AMPA receptor modulators has been recently synthesized. These compounds belong to the class of organic nitrate ester of the nitroglycerine family and are designated GT-2 1-...
متن کاملNew and Rare Carotenoids Isolated from Marine Bacteria and Their Antioxidant Activities
Marine bacteria have not been examined as extensively as land bacteria. We screened carotenoids from orange or red pigments-producing marine bacteria belonging to rare or novel species. The new acyclic carotenoids with a C₃₀ aglycone, diapolycopenedioc acid xylosylesters A-C and methyl 5-glucosyl-5,6-dihydro-apo-4,4'-lycopenoate, were isolated from the novel Gram-negative bacterium Rubritalea s...
متن کاملRational Design, Synthesis and Computational Structure-Activity Relationship of Novel 3-(4-Chlorophenyl)-5-(3-Hydroxy-4-Ethoxyphenyl)-4,5-Dihydro-1H-Pyrazole-1-Carboxamide
Densely functionalized 3-(4-chlorophenyl)-5-(3-hydroxy-4-etoxyphenyl)-4,5-dihydro-1H-pyrazole-1-carboxamide was synthesized in an expedient manner through specification and transamidation respectively, of ester-functionalized pyrazoles. This synthetic protocol allowed for three diversifying steps in which appendages on the pyrazole scaffold were adjusted to optimize inhibition of protein kina...

متن کامل5-Hydroxy-1-methyl-3,4-dihydro-2H-pyrrolium hydrogensulfate
The title compound, C(5)H(10)NO(+)·HSO(4) (-), has been synthesized by reaction of 1-methyl-pyrrolidin-2-one with H(2)SO(4) in a 1:1 molar ratio. The substituted pyrrolium ring adopts an envelope conformation. The hydrogensulfate anions form infinite helical chains parallel to the a axis via strong O-H⋯O hydrogen bonds. The pyrrolium cations are pendant from the chains. These cations are the hy...
