Described herein are compositions and methods for hormone replacement therapy that address the shortcomings of the existing methods. Described herein are pharmaceutically effective partial agonistic antiprogestins. The combined application of estrogens (such as estradiol, estriol and conjugated estrogens) and the disclosed partial agonistic antiprogestins can be used in hormone replacement therapy.

Chicken II and salmon GnRH or its analog decapeptides resistant to degradation by peptidase incorporating D-arginine, D-leucine, D-tBu-Serine, D-Trp or other active D amino acids at position 6 and ethylamide, aza-Gly-amide or other Gly amide at position 10. The non-mammalian GnRH or its analogs demonstrate preferential binding to male and female reproductive system GnRH receptors as well as tumor cell GnRH receptors in these systems. Biopotency is greater within the reproductive system and at tumor cells than at the pituitary. These non-mammalian GnRH or its analogs may be used in pharmaceutical preparations, and specifically in various treatment methods as a contraceptive or post-coital contraceptive agent. The non-mammalian GnRH or its analogs are also provided in pharmaceutical preparations that may be used clinically for maintaining pregnancy when used in very low doses and administered in pulsatile fashion, as well as in preparations for the treatment of male and female reproductive system disorders including cancers of these systems or other system with GnRH II receptors. The aza-Gly (10) amide non-mammalian analogs are yet other embodiments of the non-mammalian GnRH analogs provided as a part of the invention.
鸡 II 和鲑鱼 GnRH 或其类似物可抗肽酶降解,在第 6 位含有 D-精氨酸、D-亮氨酸、D-tBu-丝氨酸、D-Trp 或其他活性 D 氨基酸,在第 10 位含有乙酰胺、偶氮甘氨酰胺或其他甘氨酰胺。非哺乳动物 GnRH 或其类似物显示出与男性和女性生殖系统 GnRH 受体以及肿瘤细胞 GnRH 受体的优先结合。在生殖系统和肿瘤细胞中的生物活性高于垂体。这些非哺乳动物 GnRH 或其类似物可用于药物制剂,特别是在各种治疗方法中用作避孕药或性交后避孕药。这些非哺乳动物 GnRH 或其类似物还可用于药物制剂,在临床上以极低剂量和脉冲方式给药时可用于维持妊娠,以及用于治疗男性和女性生殖系统疾病,包括这些系统的癌症或具有 GnRH II 受体的其他系统。杂-甘氨酰(10)酰胺非哺乳动物类似物是作为本发明的一部分提供的非哺乳动物 GnRH 类似物的其他实施方案。

Uterine lavage is performed to withdraw at least 50% of in vivo fertilized preimplantation embryos produced after superovulation of a woman and artificial insemination using sperm of her sexual partner. Subject of the invention is a GnRH antagonist (e.g. cetrotide) alone or combined to a progesterone receptor antagonist (e.g. mifepristone) used for decreasing the risk of retained pregnancy by possibly non-withdrawn embryos. After genetic diagnosis or sex determination or gene therapy, or any combination of any two or more of them, of the recovered embryos and selection of at least one of the embryos to be implanted, the selected embryos are returned to the woman for implantation in her uterus.

Specially designed non-mammalian GnRH analog decapeptides resistant to degradation by the placental enzyme, C-ase-1, or a post-proline peptidase, are disclosed. The GnRH analogs are further defined as analogs of chicken II GnRH or salmon GnRH. These non-mammalian analogs incorporate D-arginine, D-leucine, D-tBu-Serine, D-Trp or other active D amino acids at position 6 and ethylamide, aza-Gly-amide or other Gly amide at position 10. The D-Arg (6)-chicken II GnRH-ethylamide, D-Arg (6)-chicken II GnRH-aza-Gly (10)-amide, the D-Arg (6)-salmon GnRH ethylamide, and D-Arg (6)-salmon GnRH-aza-Gly (10)-amide analogs are also provided, and demonstrate preferential binding to chorionic GnRH, ovarian, endometrial, tubal, uterine, prostate and testicular receptors. Biopotency is greater at the ovary and endometrium than at the pituitary. These non-mammalian GnRH analogs may be used in pharmaceutical preparation, and specifically in various treatment methods as a contraceptive or post-coital contraceptive agent. The non-mammalian GnRH analogs are also provided in pharmaceutical preparations that may be used clinically for maintaining pregnancy when used in very low doses and administered in pulsatile fashion, as well as in preparations for the treatment of endometriosis, ovarian cysts, and leimyomas. In another aspect, the non-mammalian GnRH analogs may be used a luteolytic agents. The aza-Gly (10) amide non-mammalian analogs are yet other embodiments of the non-mammalian GnRH analogs provided as a part of the invention.
本研究公开了专门设计的非哺乳动物 GnRH 类似物十肽,可抵抗胎盘酶 C-ase-1 或脯氨酸后肽酶的降解。GnRH 类似物进一步定义为鸡 II GnRH 或鲑鱼 GnRH 的类似物。这些非哺乳动物类似物在第 6 位含有 D-精氨酸、D-亮氨酸、D-tBu-丝氨酸、D-Trp 或其他活性 D 氨基酸,在第 10 位含有乙酰胺、偶氮甘氨酰胺或其他甘氨酰胺。还提供了 D-Arg(6)-鸡 II GnRH-乙酰胺、D-Arg(6)-鸡 II GnRH-氮-甘氨酰(10)-酰胺、D-Arg(6)-鲑鱼 GnRH 乙酰胺和 D-Arg(6)-鲑鱼 GnRH-氮-甘氨酰(10)-酰胺类似物,并显示出与绒毛膜 GnRH、卵巢、子宫内膜、输卵管、子宫、前列腺和睾丸受体的优先结合。卵巢和子宫内膜的生物活性高于垂体。这些非哺乳动物 GnRH 类似物可用于药物制剂,特别是在各种治疗方法中用作避孕药或性交后避孕药。这些非哺乳动物 GnRH 类似物还可用于药物制剂,在临床上以极低剂量和脉冲方式给药时可用于维持妊娠,还可用于治疗子宫内膜异位症、卵巢囊肿和卵巢白膜瘤。另一方面,非哺乳动物 GnRH 类似物可用作黄体溶解剂。杂-甘氨酰(10)酰胺非哺乳动物类似物是作为本发明的一部分提供的非哺乳动物 GnRH 类似物的其他实施方案。
