Design and Synthesis of Potent Hexapeptide and Heptapeptide Gonadotropin-Releasing Hormone Antagonists by Truncation of a Decapeptide Analogue Sequence
truncation strategy was successful for generation of reduced-size hexapeptide and heptapeptide antagonists possessing potent antagonistic capacity. The same methodology was not suitable for the generation of reduced-size agonists, suggesting different conformational characteristics for GnRH agonists and antagonists. A heptapeptide antagonistdesigned by this method was shown to inhibit serum levels of luteinizing
