Memory of Chirality in Diastereoselective α-Alkylation of Isoleucine and allo-Isoleucine Derivatives

Organic Letters, 2000
[reaction: see text] alpha-Methylation of 3 gave 5 as a major product whereas 4 gave 6 predominantly, although both 3 and 4 have an (S)-chiral center at C(3). This indicates that chirality at C(2) in 3 and 4 was memorized in the corresponding intermediate enolates and the induced chirality made a major contribution in the stereochemical course of the ...

Regulation of Isoleucine and Valine Biosynthesis

1978
Publisher Summary This chapter discusses the regulation of isoleucine and valine biosynthesis. Isoleucine and valine biosynthesis is a model system for the study of mechanisms by which the cell coordinates different parts of its total metabolism. Threonine deaminase is the first enzyme in isoleucine biosynthesis.

Synthesis and pharmacological properties of [5-isoleucine]-, [8-isoleucine]-, and [5,8-diisoleucine]bradykinin

Journal of Medicinal Chemistry, 1979
Three bradykinin analogues have been synthesized in which the phenylalanine residue(s) at positions 5 and/or 8 have been substituted by isoleucine. All these analogues have weak bradykinin-like activity in isolated rat uterine smooth muscle or in rat blood pressure assay. No antagonistic activity was observed with any of these analogues. The importance

Discrimination of leucine and isoleucine in peptides sequencing with Orbitrap Fusion mass spectrometer.

Analytical Chemistry, 2014
An efficient approach to easy and reliable differentiation between isomeric leucine and isoleucine in peptide sequencing utilizes multistage electron transfer dissociation and higher energy collision activated dissociation in the Orbitrap Fusion mass ...

Isoleucine requirement of pregnant sows1

Journal of Animal Science, 2013
The objective of this study was to determine the Ile requirement in early (d 39 to 61) and late (d 89 to 109) pregnancy using the indicator AA oxidation method. The same 7 Large White × Landrace sows in their fourth parity were used in early and late pregnancy.
