Description

Buserelin is a longer acting synthetic peptide analog of the naturally occurring gonadotropin-releasing hormone (GnRH/LHRH). Substitution of glycine in position 6 by D-serine and that of glycinamide in position 10 by ethylamide, leads to a nonapeptide with a significantly enhanced LHRH effect. The effects of buserelin on follicle-stimulating hormone (FSH) and luteinizing hormone (LH) release are approximately 20 to 170 times higher than those of natural LHRH.
