    • Antide is the decapeptide, N--Ac--D--2--Nal,D--pClPhe, D--3--Pal, Ser,NicLys, D--NicLys, Leu, ILys, Pro, D--Ala,NH.sub.2 which is an antagonist of luteinizing hormone releasing hormone (LHRH). This decapeptide, like others of the present invention, has high antiovulatory activity (AOA) and releases negligible histamine. Antide is scheduled for scale-up, safety testing and evaluation in the experimental primate and in clinical medicine. Numerous other peptides having structures related to Antide were prepared and tested. These peptides had variations primarily in positions 5, 6, 7, and 8. Of these, N--Ac--D--2--Nal, D--pClPhe,D--3--Pal,Ser,PicLys,cis--DpzACAla, Leu,ILys,pro,D--Ala--NH.sub.2 was one of the most potent and had higher antiovulatory activity than Antide, i.e. 73%/0.25 ug and 100%/0.5 ug vs. 36%/0.5 ug and 100%/1.0 ug. Antide showed significant, (p
    • Antide是黄素化拮抗剂的十肽,N-Ac-D-2-Nal,D-pClPhe,D-3-Pal,Ser,NicLys,D-NicLys,Leu,ILys,Pro,D-Ala,NH2 激素释放激素(LHRH)。 这种十肽与本发明的其它物质一样,具有高的抗疟药活性(AOA),释放出可忽略的组胺。 Antide计划在实验灵长类动物和临床医学中进行放大,安全测试和评估。 制备并测试了许多具有与Antide有关的结构的其它肽。 这些肽主要在第5,6,7和8号位置有变化。其中,N-Ac-D-2-Nal,D-pClPhe,D-3-Pal,Ser,PicLys,cis-DpzACAla,Leu,ILys ,pro-D-Ala-NH2是最有效的并且具有比Antide更高的抗肿瘤活性,即73%/ 0.25ug和100%/ 0.5ug,而36%/ 0.5ug和100%/1.0μg。 当在50ng激动剂[D-3-Qal6] -LHRH之前以10μg,44小时的剂量注射时,Antide显示显着的(p <0.001)作用持续时间。 Antide在600ug(73%)和1200μg(100%)下显示口服AOA,水和玉米油口服制剂之间的差异可以忽略不计。
