Nα-quinaldyl-L-arginine·HCl, a new defensive alkaloid from Subcoccinella-24-punctata (Coleoptera, Coccinellidae)

Article abstract of DOI:10.1007/BF01969744

The isolation of Nα-quinaldyl-L-arginine·HCl (1) from the Coccinellidae Subcoccinella-24-punctata is reported. The structure, first established on the basis of the analysis of the spectral properties of 1, has been confirmed by synthesis. The alkaloid is of endogenous origin and markedly deterrent to ants.
