Abstract:
(11) Potassium ferricyanide has previously been used to convert w'c-1,2-dicarboxylate groups to double bonds. See, for example, L. F. Fieser and M. J. Haddadln, J. Am. Chem. Soc., 86, 2392 (1964). The oxidative dldecarboxylation of 1,2-dlcarboxyllc acids is, of course, a well-known process. See Inter alia (a) C. A. Grob, M. Ohta, and A. Weiss, Helv. Chim. Acta, 41, 1911 (1958); and (b) E. N. Cain, R. Vukov, and S. Masamune, J. Chem. Soc. D, 98 (1969).read more

Methods for preparing internally constrained peptides and peptidomimetics
TL;DR: In this article, a method for preparing a peptide having a stable, internally constrained alpha-helical, beta-sheet/beta-turn, 310-helico, or pihelical region was presented.

Biosynthetic Origin of Gibberellins A3 and A7 in Cell-Free Preparations from Seeds of Marah macrocarpus and Malus domestica
TL;DR: Cell-free preparations from seeds of Marah macrocarpus L. and Malus domestica catalyzed the conversion of gibberellin A(9) (GA(9)) and 2,3-dehydroGA( 9) to GA(7) in a branch pathway, providing further evidence that the biosynthetic origin of GA(3) and GA( 7) in higher plants is different from that in the fungus Gibberella fujikuroi.

TL;DR: ITO activation and formation of these copolymer films enhances the electroactive fraction of the electrode surface relative to a nonactivated, unmodified "blocked" ITO electrode.

Interaction Between the Antibiotic Trichothecenes and the Higher Plant Baccharis megapotamica.
TL;DR: Feeding experiments with fungus-produced trichothecenes show that Baccharis megapotamica absorbs, translocates, and chemically alters these compounds to ones with structures analogous to those found in the plant in its native habitat.

TL;DR: Data validate the approach to rationally identify new target-specific bioactive β-lactam potentiation agents and demonstrate that murgocil now serves as a highly selective and potent chemical probe to assist the understanding of PG biosynthesis and cell wall biogenesis across Staphylococcal species.
