  An approach to the elucidation of metabolic breakdown products of the luteinizing hormone-releasing hormone

  摘要：

  Metabolic breakdown of the luteinizing hormone-releasing hormone (LH-RH) could lead to the following fragments containing pyroglutamic acid: pyroglutamic acid (1), pGlu-His (2), pGLu-His-Trp (3), pGlu-His-Trp-Ser (4), etc., and finally pGlu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly (10). We have synthesized fragments 2-10 and successfully separated all ten metabolites and LH-RH by high-performance liquid chromatography (HPLC) with a muBondapak C18 column. In a test of the viability of the method, cochromatography of fragments 1-10 and LH-RH with the products of chymotryptic digestion of tritiated LH-RH showed radioactive peaks corresponding to the expected products, fragments 3 and 5. Analysis of the products of incubation of a rat kidney homogenate supernatant with LH-RH showed fragments 1-4 and LH-RH. The finding of breakdown at position 4 uncovers a new site of LH-RH breakdown and points the way to the design of potential LH-RH antagonists and agonists where the 4 position would be substituted with unnatural amino acids to prevent breakdown.

  A synthetic decapeptide, L-pglutamyl-L-histidyl-L-tryptophanyl-L-seryl-L-tyrosyl-glycyl-L-leucyl-L- arginyl-L-prolyl-glycinamide which has the hormonal activities of the luteinizing hormone releasing hormone (LRH) of the hypothalamus gland of mammals is produced by utilizing as the key starting materials, the amino acids, glutamic acid or pyroglutamic acid, histidine, tryptophan, serine, tyrosine, glycine, leucine, arginine, and proline. Synthesis of the decapeptide is accomplished by coupling, in appropriate combinations of appropriate protected forms of the amino acids, and finally deprotecting to yield the amide, L-pglutamyl-L-histidyl-L-tryptophanyl-L-seryl-L-tyrosyl-glycyl-L-leucyl-L- arginyl-L-prolyl-glycinamide.
