The structure and synthesis of malformin A

Abstract

  • A structure (the disulfide form of cyclo-D-cysteinyl-L-valyl-D-cysteinyl-D-leucyl-L-isoleucyl), previously proposed for malformin A, was reexamined. On the basis of chemical degradations, a different structure (the disulfide form of cyclo-D-cysteinyl-D-cysteinyl-L-valyl-D-leucyl-L-isoleucyl) was established. Accordingly, a compound with this structure was synthesized and was found to be identical with malformin A. The synthetic product causes curvatures on corn roots; maximum effect was seen at a concentration of 0.1 mug/ml, the optimal concentration for malformin A.

Allomalformin

Abstract

  • In an attempt to find explanation for the initial erroneous sequence assignment for malformin, a sequence-isomer of the natural product, 3-isoleucine-5-valine malformin or briefly "allomalformin" that on partial acid hydrolysis could have given rise to misleading fragments, was synthesized and compared with both natural and synthetic preparations of malformin. Allomalformin is identical to the parent microbial peptide (malformin A, or briefly malformin) with respect to biological activity and conformation (ORD and CD spectra) and is indistinguishable from it by high pressure liquid chromatography. Yet, the two isomers have slightly different Rf values on thin-layer chromatograms and by this method no allomalformin could be detected in samples of the natural product. On the other hand both high pressure liquid chromatography and thin-layer chromatography demonstrated the presence of the lower homolog, 5-valine malformin, in the samples examined. On partial acid hydrolysis this natural analog should liberate Val-Cys, while Cys-Val forms from malformin itself. Similarly, the corresponding desthio cyclopentapeptides should give rise to Val-Ala and Ala-Val respectively; the former being more resistant to further hydrolysis persists in the partial hydrolysates. The presence of Val-Cys in partial hydrolysates of malformin and of Val-Ala in the partial hydrolysates of desthiomalformin, both originating from the accompanying lower homolog rather than from malformin itself, is likely to have led to the postulation of the erroneous Cys-Val-Cys partial sequence.

Biosci Biotechnol Biochem

Structure of malformin B, a phytotoxic metabolite produced by Aspergillus niger

Abstract

  • Malformin B, produced by Aspergillus niger, was separated into six compounds by HPLC. Their structures were determined by amino acid analyses, and by mass spectral and two-dimensional NMR experiments to be cyclic pentapeptides structurally related to malformin A1. Both the NMR and MS/MS experiments suggest cyclo-D-cysteinyl-D-cysteinyl-L-amino acid-D-amino acid-L-amino acid as the essential structure of malformins.
