General description

Pyrithiamine hydrobromide is a heterocyclic building block that is used as a valuable tool in organic synthesis and medicinal chemistry due to its ability to mimic thiamine deficiency and its potential for the development of new compounds with useful pharmacological properties.

Application

Pyrithiamine hydrobromide can be used as a precursor for the synthesis pyrithiamine pyrophosphate.

Riboswitches are untranslated regions of messenger RNA, which adopt alternate structures depending on the binding of specific metabolites. Such conformational switching regulates the expression of proteins involved in the biosynthesis of riboswitch substrates. Here, we present the 2.9 angstrom-resolution crystal
