This result agrees with the proposal that preferential equatorial attack of a nucleophile is caused by conformational factors related to a steroid non-steroid conformation equilibrium in thecis-isomers.[Journal Translation]C. AgamiT. RizkR. DurandP. Genestecanadian journal of chemistry...
Variations of these activities were checked in the transfer cells of the cotyledonary node in the intact or decapitated plant. They were also studied in the shoot apex of both inhibited (G0state) and released cotyledonary buds, during the transitions G1–S orG2–M. The adenylate cyclase ...
The effect is reversible. This result supports the idea that the local ERG recorded in the inner plexiform layer is closely associated with changes in extracellular K + activity.Pournaras, K. IKarwoski, C. JTsacopoulos, MKlinische Monatsbltter Für Augenhlkunde...
buten-1-one, 4-amino-3-penten-2-one, various 3-aminocrotonic esters and amides react with 1-phenylpyrazolidin-3,5-dione to yield compounds resulting from the elimination of ammonia between the two precursors and the so obtained derivatives cyclize on heating to pyrano [2,3-c] pyrazoles....

Study of the reactivity of Bis-1,1'-[4-phenyl 2-oxo 1,5-benzodiazepine 1-yl]methane allowed us to throw into relief different reactive site of this type of molecule.Achour, ReddouaneLaboratoire de Chimie Organique Hétérocyclique, Département de Chimie, Faculté des Sciences, Avenue Ibn Bat...
1-phenyl-3-methylpyrazolin-5-one, 1,5-dimethylpyrazolin-3-one and 1-phenyl-pyrazolidin-3,5-dione react with ethyl acetoacetate to yield pyrano [2,3-c] pyrazole-6-ones. Starting from 1-phenyl-3-aminopyrazolin-5-one or from 1-methyl-5-aminopyrazolin-3-one, pyrazolo [3,4-b] ...
A polynucleotide phosphorylase with a molecular weight of 100,000 has been isolated from Escherichia coli Q13 mutant and partially purified. This mutant is particularly rich in this low molecular species which can, however, also be found in small proportion in wild strains of E. coli B and K12...
