The anti-LH-releasing activity of several analogues of LH-RH was tested by 2-hour infusion in ovariectomized, estrogen-progesterone-pretreated rats and in immature male rats. [Leu3]LH-RH, [Leu3, desGly10]-LH-RH ethylamide, [desHis2, Leu3,desGly10]-LH

In previous reports illustrating the effects of conformational restriction of the N-terminal region of human pancreatic growth hormone releasing factor, we demonstrated that D-amino acid substitutions in either of positions 1, 2, or 3 resulted in gre

Luteinizing hormone (LH)-releasing activity of 8 potent LH-releasing hormone (RH) analogs was investigated in primary cultures of anterior pituitary cells. Introduction of the C-terminal ethylamide modification into (D-Ala 6) - LH-RH were 90 and 100

[Leu 6 ,desGly-NH 2 10 ]-LH-RH ethylamide and [Leu 6 ]-LH-RH, two analogs of LH-RH, were prepared by the solid phase method. LH- and FSH-releasing activity of these peptides was assayed against LH-RH by subcutaneous administration in immature male ra

The anti-LH-releasing hormone (LHRH) activity of des-His2-desGly10-LH-RH ethylamide (antagonist I), an analogue of LH-RH, was studied in several animal systems. An iv infusion of antagonist 1 for 2 hr significantly inhibited LH release in response to

Improved inhibitors of LH-RH are those which, beside removal of the histidine residue at position 2 of LH-RH, include replacement of glycine at position 6 by a D-amino acid. A still better modification is replacement of the histidine residue at posit

A series of C-terminally fluorinated analogs of luteinizing hormone-releasing hormone (LH-RH) was synthesized by a combination of solid-phase and classical techniques and found to have interesting properties when assayed for LH- and FSH-releasing act

Inhibitory activity of 4 analogs of luteinizing hormone-releasing hormone (LH-RH) in vivo was studied in rats. 30 mcg of (des-His D-Ala )-LH-RH (des-His D-Leu )-LH-RH or (D-Phe D-Leu )-LH-RH in 2 equal doses administered 20 minutes prior and at the t
