The present invention provides a β-chitin complex composed of an inclusion compound formed by using a β-chitin as a host and a guest compound which is a compound having a functional group that can form a hydrogen bond with a hydroxyl group and/or an amide group of the β-chitin and having a melting point of at least 60°C. The β-chitin complex is prepared by a method comprising the step of heating a guest compound to its melting point or higher to prepare a melt of the guest compound and the step of immersing an anhydrous β-chitin in this melt, or a method comprising the step of dissolving or suspending a guest compound in a solvent to prepare a guest carrier solution and the step of immersing a β-chitin in the guest carrier solution.
Novel inhibitors of DXP synthase and methods of use thereof are disclosed.

glyoxylate to form tartronate semialdehyde (TSA). This enzyme is unique among ThDP enzymes in that it lacks a conserved glutamate near the N1′ atom of ThDP (replaced by Val51) or any other potential acid–base side chains near ThDP. The V51D substitution shifts the pH optimum to 6.0–6.2 (pKa of 6.2) for TSA formation from pH 7.0–7.7 in wild-type GCL. This pKa is similar to the pKa of 6.1 for the 1′,4′-iminopyrimidine

Thiamin pyrophosphate was synthesized in 71% yield, on a multi-milligram scale, using overexpressed thiazole kinase, pyrimidine kinase, thiamin phosphate synthase, and thiamin phosphate kinase. This provides a facile route to isotopically labeled thiamin pyrophosphate from its readily available pyrimidine and thiazole precursors.
