Ensemble switching unveils a kinetic rheostat mechanism of the eukaryotic thiamine pyrophosphate riboswitch. [PDF]

open access: yesRNA, 2021
Thiamine pyrophosphate (TPP) riboswitches regulate thiamine metabolism by inhibiting the translation of enzymes essential to thiamine synthesis pathways upon binding to thiamine pyrophosphate in cells across all domains of life.

The Changes in Antioxidant Activity of Selected Flavonoids and Caffeine Depending on the Dosage and Form of Thiamine

open access: yesMolecules, 2021
Phenolic compounds and thiamine may serve as therapies against oxidative stress-related neurodegenerative diseases. However, it is important to note that these components show high instability under changing conditions.

Biosynthesis of Thiamin Pyrophosphate [PDF]

open access: yesEcoSal Plus, 2009
The biosynthesis of thiamin pyrophosphate (TPP) in prokaryotes, as represented by the Escherichia coli and the Bacillus subtilis pathways, is summarized in this review. The thiazole heterocycle is formed by the convergence of three separate pathways.

Open-chain thiamine analogues as potent inhibitors of thiamine pyrophosphate (TPP)-dependent enzymes.

open access: yesOrganic and biomolecular chemistry, 2023
A common approach to studying thiamine pyrophosphate (TPP)-dependent enzymes is by chemical inhibition with thiamine/TPP analogues which feature a neutral aromatic ring in place of the positive thiazolium ring of TPP.

Pumpkin, Cauliflower and Broccoli as New Carriers of Thiamine Compounds for Food Fortification

open access: yesFoods, 2021
The aim of the study is to explore the possibility of vegetables being used as carriers of thiamine. The influence of carrier type (thiamine hydrochloride—TCh and thiamine pyrophosphate—TP) for the thiamine stability were investigated.

Differences in the efficiency of 3-deazathiamine and oxythiamine pyrophosphates as inhibitors of pyruvate dehydrogenase complex and growth of HeLa cells in vitro

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2021
Oxythiamine (OT) and 3-deazathiamine (DAT) are the antimetabolites of thiamine. The aim of study was to compare the effects of OT and DAT pyrophosphates (-PP) on the kinetics of mammalian pyruvate dehydrogenase complex (PDHC) and the in vitro culture of ...
