δ--α-aminoadipoyl--cysteinyl--propargylglycine, δ--α-aminoadipoyl--cysteinyl--cyanoalanine and δ--α-aminoadipoyl--cysteinyl--[4,4,5,5-2H4]-norvaline were synthesised and incubated with the enzyme IsopenicillinNSynthase (IPNS). All incubation mixtures contained biologically active products, and led to the isolation of four new penicillins (β-ethyl, α-acetylenic, α- and β-nitrile) following purification by
