Described herein are novel isolated compounds from Leptospermum honey and methods of assay thereof for use in the verification of the place of origin, authenticity and content of Leptospermum honeys such as mānuka honey. The inventors screened flower nectar and honeys of various floral types found in New Zealand to identify chemicals that were either unique to or in significantly higher concentrations in mānuka nectar and mono-floral mānuka honey compared to other predominantly mono-floral nectars and honeys. As a result of the screening exercise, the inventors discovered a marker compounds that could distinguish Leptospermum honey nectar and honey from other floral sources.

The development of a versatile solid phase synthesis of bicyclic polyaza heterocycles including pteridines, purines, and deazapurines is described. The strategy comprises the linking of a pre-formed pyrimidine through a thioether at the 2 or 4 position to a polystyrene resin, the cyclisation of the second ring, and the direct or oxidative cleavage of the product from the resin by nucleophilic substitution

The linking of pyrimidines to polystyrene supports via either a 2- or 4-thioether provides access to pteridines through solid-phasesynthesis. Oxidative cleavage (dimethyldioxirane) followed by nucleophilic substitution by amines, azide, or water completes a tracelesssynthesis of pteridines.
selectively binds to adenine (A) base opposite the abasic site in DNA duplexes (5'-TCC AGX[combining low line] GCA AC-3'/3'-AGG TCN CGT TG-5', X = AP site (Spacer C3), N= A, T, C and G) than the other three nucleobases with a dissociationconstant K(d) of ca. 1.0 microM; substituted methyl groups enhance the binding affinity to A and the selectivity for A over T, compared to the parent molecule, lumazine
