We describe an application of the backbone cyclization and cycloscan concept for the design and synthesis of pheromone biosynthesis activating neuropeptide (PBAN) antagonists capable of inhibiting… Expand
Advances in the application of neuropeptides in insect control
Abstract The development of a new approach for the generation of a novel type of putative insect control agents based on backbone cyclic peptidomimetic antagonists of insect-neuropeptides is… Expand
Pheromone biosynthesis activating neuropeptide (PBAN) and colour polymorphism: an immunochemical study in Spodoptera littoralis
Abstract PBAN (also termed melanization and reddish colouration hormone—MRCH) is a cerebral factor known to regulate sex pheromone biosynthesis, cuticular melanization and epidermal reddish brown… Expand
Discovery of a linear lead antagonist to the insect pheromone biosynthesis activating neuropeptide (PBAN)☆
We report the discovery of a linear lead antagonist for the insect pheromone biosynthesis activating neuropeptide (PBAN) which inhibits sex pheromone biosynthesis in the female moth Heliothis… Expand
Inhibition of PK/PBAN-mediated functions in insects: Discovery of selective and non-selective inhibitors
The antagonistic properties of a few linear and backbone cyclic (BBC) conformationally constraint peptide libraries and their analogs, were tested for the ability to inhibit pyrokinin/pheromone… Expand
PBAN selective antagonists: inhibition of PBAN induced cuticular melanization and sex pheromone biosynthesis in moths.
A D-Phe scan (sequential D-Phe replacement) library of linear peptides, synthesized on the basis of a slightly modified active sequence of PBAN (YFSPRL-amide) was employed to detect potential… Expand
Characterization of a putative pheromone biosynthesis-activating neuropeptide (PBAN) receptor from the pheromone gland of Heliothis peltigera.
The binding of [3H]tyrosyl-PBAN28-33NH2 to pheromone gland membranes of the moth Heliothis peltigera was investigated. The study describes the development of a pheromone biosynthesis-activating… Expand
