Gm. Blackburn et al., Synthesis of haptens and their protein conjugates for immunological determination of nitrate esters and nitramines, J CHEM S P1, (2), 2000, pp. 225-230
Isosteric, isopolar analogues of the nitrate ester pentaerythritol tetranit
rate (PETN) and of the cyclic nitramine sym-cyclotrimethylene trinitramine
(RDX) having a spacer arm have been linked to carrier proteins to provide i
mmunologically active peptide conjugates. X-Ray structures of RDX, RDX anal
ogue 10, and hapten 14 are compared to establish their conformational relat
ionships.
