A method for determining the presence of mycobacteria species in an organism or biological sample, the method comprising adding to the organism or biological sample a probe molecule comprising a substrate and a label, which probe molecule can be incorporated into mycobacteria, the presence of mycobacteria being determined by a detector responsive to the presence of the label, optionally after applying a stimulus; suitable probe molecules include compounds comprising a label and a substrate, which label is can be detected by a detector responsive to the presence of the label, optionally after applying a stimulus, characterised by compound being able to engage with the active site of Antigen 85B (Ag85B) such that it can form simultaneous hydrogen bonds with two or more amino acids in the active site selected from Arg 43, Trp 264, Ser126, His 262 and Leu 42, or the corresponding amino acids in Antigen 85A (Ag85A) or Antigen 85C (Ag85C), at least one of which is with Ser126.

Phosphate esters in polyhydroxylated systems are normally blighted by uncontrolled migration under a variety of reaction conditions. Cesium fluoride is demonstrated as a reagent to control migration of primary phosphates during transesterifications. This allows easy exchange of phosphoryl protecting groups enabling enhanced synthetic strategic flexibility and regioselective phosphate installation.
