Indole-3-Acetic Acid Produced by Burkholderia heleia Acts as a Phenylacetic Acid Antagonist to Disrupt Tropolone Biosynthesis in Burkholderia plantarii
Burkholderia heleia PAK1-2 is a potent biocontrol agent isolated from rice rhizosphere, as it prevents bacterial rice seedling blight disease caused by Burkholderia plantarii. Here, we isolated a… Expand
Synthesis of Methoxy-Substituted Diazirinyl Phenylalanine – A Novel Photoreactive Aspartame Derivative for Functional Analysis of Sweet Receptors
Photoreactive phenylalanine derivatives are well known as functional analysis reagents for target biomolecules. The photophores are commonly introduced at 4-position on benzene. Aspartame, which… Expand
Comparisons of O-acylation and Friedel–Crafts acylation of phenols and acyl chlorides and Fries rearrangement of phenyl esters in trifluoromethanesulfonic acid: effective synthesis of optically…
Abstract Reactions involving phenol derivatives and acyl chlorides have to be controlled for competitive O-acylations and C-acylations (Friedel–Crafts acylations and Fries rearrangements) in acidic… Expand
Alternative one-pot synthesis of (trifluoromethyl)phenyldiazirines from tosyloxime derivatives: application for new synthesis of optically pure diazirinylphenylalanines for photoaffinity labeling.
Alternative one-pot synthesis of 3-(trifluoromethyl)-3-phenyldiazirine derivatives from corresponding tosyloximes is developed. The deprotonation of intermediate diaziridine by NH2(-) is a new… Expand
Ralstonins A and B, Lipopeptides with Chlamydospore-Inducing and Phytotoxic Activities from the Plant Pathogen Ralstonia solanacearum.
Ralstonia solanacearum has an orphan hybrid polyketide synthase-nonribosomal peptide synthetase gene cluster. We herein isolate its products (named ralstonins A and B) from R. solanacearum and… Expand
Rapid and Controllable Hydrogen/Deuterium Exchange on Aromatic Rings of α‐Amino Acids and Peptides
Novel hydrogen/deuterium exchange for aromatic α-amino acids and their corresponding peptides were performed through the use of deuterated trifluoromethanesulfonic acid (TfOD). Detailed analysis of… Expand

In this paper we report here a hydrogen/deuterium exchange (H/D exchange) of cross-linkable α-amino acid derivatives with deuterated trifluoromethanesulfonic acid (TfOD). H/D exchange with TfOD was… Expand
Cerebral oximetry for cardiac surgery: a preoperative comparison of device characteristics and pitfalls in interpretation
Regional cerebral oximetry using near-infrared spectroscopy devices is commonly used for detecting cerebral ischemia during cardiopulmonary bypass, and aim to avoid poor cerebral perfusion which may… Expand
Synthesis of Photoreactive 2‐Phenethylamine Derivatives – Synthesis of Adenosine Derivatives Enabling Functional Analysis of Adenosine Receptors by Photoaffinity Labeling
2-Phenylethylamine is well known as a substructure of many biologically active compounds, and the synthesis of its photoreactive derivatives to allow the analysis of biological functions is reported.… Expand
