Mimetic insect kinin analogs for insect control

摘要

Novel pseudopeptide analogs of the insect kinin neuropeptide family which possess biological activity mimicking that of the naturally occurring neuropeptides are disclosed. By substituting a sterically hindered amino acid which is compatible with a turn conformation, for the Xaa2 amino acid of the insect kinin C-terminal pentapeptide (i.e. Ser, Pro, or Ala), analogs are produced which exhibit resistance to degradation by angiotensin converting enzyme (ACE) while still retaining biological activity. The analogs may be used for insect control by disrupting the diuretic and/or myotropic activity in insects.
