Supramolecular Tandem Assay for Pyridoxal‐5′‐phosphate by the Reporter Pair of Guanidinocalix[5]Arene and Fluorescein

open access: yesChemistryOpen, 2019
Guanidinocalix[5]arene and fluorescein reporter pair has been chosen to set up a supramolecular tandem assay principle based on the differential recognition of pyridoxal‐5′‐phosphate (the substrate of alkaline phosphatase, ALP), pyridoxal (the product of

Pyridoxine dependent epilepsies: new therapeutical point of view

open access: yesItalian Journal of Pediatrics, 2017
Pyridoxine dependent epilepsies (PDEs) are rare autosomal recessive disorders with onset in neonatal period. Seizures are typically not responsive to conventional antiepileptic drugs, but they cease after parental pyridoxine administration.

Pyridoxal 5'-phosphate is a slow tight binding inhibitor of E. coli pyridoxal kinase. [PDF]

open access: yesPLoS ONE, 2012
Pyridoxal 5'-phosphate (PLP) is a cofactor for dozens of B(6) requiring enzymes. PLP reacts with apo-B(6) enzymes by forming an aldimine linkage with the ε-amino group of an active site lysine residue, thus yielding the catalytically active holo-B(6 ...

PLP Induced Inhibition of Thymidylate Synthase Activity in T Lymphocytes

open access: yesEuropean Journal of Inflammation, 2003
The present study was undertaken in order to examine whether pyridoxine may be used as an inhibitor of thymidylate synthase, and thus, as an antiproliferative agent.

Stability-indicating HPLC-PDA assay for simultaneous determination of paracetamol, thiamine and pyridoxal phosphate in tablet formulations

open access: yesActa Pharmaceutica, 2019
With the increased number of multi-drug formulations, there is a need to develop new methods for simultaneous determinations of drugs. A precise, accurate and reliable liquid chromatographic method was developed for simultaneous determination of ...

Identification of atropine-and P2X1 receptor antagonist-reistant, neurogenic contractions of the urinary bladder [PDF]

open access: yes, 2007
Acetylcholine and ATP are excitatory cotransmitters in parasympathetic nerves. We used P2X1 receptor antagonists to further characterize the purinergic component of neurotransmission in isolated detrusor muscle of guinea pig urinary bladder.
