Vanadyl complexes with dansyl-labelled dipicolinic acid ligands: synthesis, phosphatase inhibition activity and cellular uptake studies [PDF]

open access: yes, 2016
Vanadium complexes have been previously utilised as potent inhibitors of cysteine based phosphatases (CBPs). Herein, we present the synthesis and characterisation of two new fluorescently labelled vanadyl complexes (14 and 15) with bridged di-picolinic ...

Mn2+ Bispidine Complexes as Potential Magnetic Resonance Imaging Agents : Noncoordinating Peripheral Functional Groups Affect Structural, Kinetic, and Relaxation Properties

open access: yesChemistryEurope, Volume 4, Issue 1, January 2026.
In the family of Mn2+ complexes formed with pentadentate bispidine chelates, functional groups that do not interfere with metal coordination can play a significant role in enhancing kinetic inertness and proton relaxation efficacy. Mn2+ bispidine complexes combine unprecedented kinetic inertness with high relaxivity and are under scrutiny as potential ...

Isomerization of α‐Pinene Oxide to Trans‐Pinocarveol

open access: yesHelvetica Chimica Acta, Volume 109, Issue 1, January 2026.
An operationally simple protocol for the selective isomerization of α‐pinene oxide (APO) to trans‐pinocarveol (TPC) is disclosed, which leverages inexpensive pyridinium‐halide organocatalysts to mitigate competing 1,2‐alkyl shifts. The scalability of this methodology is demonstrated on a decagram scale and catalyst‐recycling is validated through the ...

Biosynthesis of Mycotoxin Fusaric Acid and Application of a PLP-Dependent Enzyme for Chemoenzymatic Synthesis of Substituted l-Pipecolic Acids.

open access: yesJournal of the American Chemical Society, 2020
Fusaric acid (FA) is a well-known mycotoxin that plays an important role in plant pathology. The biosynthetic gene cluster for FA has been identified, but the biosynthetic pathway remains unclarified.

Omega-3 fatty acid supplementation affects tryptophan metabolism during a 12-week endurance training in amateur runners: a randomized controlled trial

open access: yesScientific Reports
The effects of long-term omega-3 polyunsaturated fatty acid (n-3 PUFA) supplementation during endurance training on tryptophan (Trp) metabolism and mental state of healthy individuals have not been evaluated so far.

Support Vector Machine Identification of Small Molecule Binders to an Understudied Allosteric Site of SARS‐CoV‐2 Mpro for Next‐Generation PROTAC‐Based Therapeutics

open access: yesArchiv der Pharmazie, Volume 358, Issue 12, December 2025.
An SVM‐based ML model identified 180 potential SARS‐CoV‐2 Mpro inhibitors. MST experiments confirmed three high‐affinity binders, with one showing Kd = 2.8 ± 0.9 μM. These compounds are non‐competitive, suggesting binding to a novel allosteric site.

Biodegradation of Picolinic Acid by Rhodococcus sp. PA18 [PDF]

open access: yesApplied Sciences, 2019
Picolinic acid (PA), a C2-carboxylated pyridine derivative, is a significant intermediate used in industrial production. PA is considered hazardous for the environment and human health. In this study, a Gram-positive bacterium, Rhodococcus sp. PA18, which aerobically utilizes PA as a source of carbon and energy, was isolated.

Plectranthus‐derived Abietanes as Protein Kinase C‐δ Activators: In Silico Design, Human Serum Albumin Interaction, and Stability Evaluation

open access: yesChemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT Cancer remains a major global health challenge. Among protein kinases (PKCs), PKC‐δ acts as a tumor suppressor in colon cancer and represents a valuable therapeutic target. Human serum albumin (HSA) is gaining attention as an efficient drug carrier, while Plectranthus spp. offers a rich source of bioactive compounds.
