Living Supramolecular Compounds: Influence of Multiple Hydrogen Bond Connection on Molecular Configuration of Monophosphate or Pyrophosphate Thiamine with Anions or Coordination Anions

Abstract

(3) (TPP = thiamine pyrophosphate, TMP = thiamine monophosphate) were synthesized in methanol or water systems at room temperature. They were characterized by elemental analysis, IR spectrocopy, and single X-ray

Thiazolium Salts as Chalcogen Bond Donors

“…They also indicate that transformation of chalcogenazoles into the corresponding chalcogenazolium derivatives typically increases the propensity of sulfur and other chalcogens to form ChBs. This finding may have far reaching consequences thanks to the numerous and useful properties of these moieties, spanning biopharmacology, ,− material sciences, ,, and synthetic chemistry. , The identification of ChBs in crystals of thiamine monophosphate 4 and in the two organocatalysts 5 and 6 exemplifies the relevance of the ChB donor ability in functionally important thiazolium compounds.…”

“…Many dyes commonly used for in vitro and in vivo imaging contain the benzothiazolium system as a component of the fluorophore moiety. Thioflavin T − and thiazole orange , (Scheme ) are the more frequently employed compounds, but many other such derivatives are used and commercially available, − owing to their biological activity and ability to act as photocurrent doping agents …”
