Salicylic Acid and N-Hydroxypipecolic Acid at the Fulcrum of the Plant Immunity-Growth Equilibrium
Frontiers in Plant Science, 2022 Salicylic acid (SA) and N-hydroxypipecolic acid (NHP) are two central plant immune signals involved in both resistance at local sites of pathogen infection (basal resistance) and at distal uninfected sites after primary infection (systemic acquired ...

Plant, Cell &Environment, EarlyView.ABSTRACT Polyamines are key regulators of plant stress responses, yet their contribution to coordinating local immune responses with systemic immunity remains poorly understood. Here, we investigated how spermine (Spm) homeostasis influences local and systemic defence responses in Arabidopsis thaliana following inoculation with Pseudomonas syringae pv.

A versatile route towards 6-arylpipecolic acids
Beilstein Journal of Organic ChemistryPipecolic acid is known as a non-proteinogenic amino acid with a secondary amine. It contains a six-membered ring and is, like its five-membered correlate, known for its secondary structure inducing properties, which are particularly useful in the design

Optimization of the precursor supply for an enhanced FK506 production in Streptomyces tsukubaensis
Frontiers in Bioengineering and Biotechnology, 2022 Tacrolimus (FK506) is a macrolide widely used as immunosuppressant to prevent transplant rejection. Synthetic production of FK506 is not efficient and costly, whereas the biosynthesis of FK506 is complex and the level produced by the wild type strain ...

Novel Amino Acid Changes Increase Phosphoenolpyruvate Carboxylase Output in planta
Plant, Cell &Environment, Volume 49, Issue 11, Page 8306-8321, November 2026.ABSTRACT Characterization of previously reported Arabidopsis mutants with increased aluminum (Al) resistance (alr) resulting from greater release of Al‐chelating malate identified three unique amino acid substitutions that each impacts PHOSPHOENOLPYRUVATE CARBOXYLASE 1, a key anaplerotic carbon fixation enzyme.

Pipecolic Acid-Catalyzed Direct Asymmetric Mannich Reactions
, 2016 Mannich reactions between aldehydes and N-p-methoxyphenyl-protected α-imino ethyl glyoxylate have been performed using (S)-pipecolic acid as catalyst. The reactions give both syn- and anti-products (dr = 1.4−2:1) with high enantioselectivities (>98% ee).

Polyphenol‐Rich Foods as a Healthy and Sustainable Strategy: Mental Health and Metabolomic Profiling
Molecular Nutrition &Food Research, Volume 70, Issue 19, 15 October 2026.A 12‐week nutritional intervention with cocoa flavanols and red‐berry anthocyanins in older adults improved emotional well‐being and identified metabolomic signatures associated with the intervention through urinary metabolome profiling. ABSTRACT The so‑called demographic transition has increased the prevalence of chronic diseases in adults over 65 ...
