Abstract: This invention provides superactive analogs of FSH demonstrating enhanced bioactivity both in vitro and in vivo as compared to wild type FSH. In particular, the analogs of the invention demonstrate at least a ten fold increase in potency or at least a ten percent increase in maximal efficacy as compared to wild type protein. The analogs are particularly useful for treating subjects showing low FSH receptor expression or poor FSH receptor responsiveness, and for the treatment of any condition associated with glycoprotein hormone activity.
Abstract translation: 与野生型FSH相比,本发明提供FSH的超活性类似物,其表现出体外和体内增强的生物活性。 特别地,与野生型蛋白质相比,本发明的类似物表现出至少十倍的效力增加或最大功效的至少百分之十的增加。 类似物对于治疗显示低FSH受体表达或不良FSH受体反应性的受试者以及用于治疗与糖蛋白激素活性相关的任何病症特别有用。

Abstract: The invention is directed toward a human glycoprotein hormone having at least one, two, three, four, or five basic amino acids in the α-subunit at positions selected from the group consisting of positions 11, 13, 14, 16, 17, and 20. The invention is also directed to a human glycoprotein where at least one of the amino acids at position 58, 63, and 69 of the β-subunit of the human thyroid stimulating hormone are basic amino acids. The invention is further directed to a modified human glycoprotein hormone having increased activity over a wild-type human glycoprotein hormone, where the modified human glycoprotein comprises a basic amino acid substituted at a position corresponding to the same amino acid position in a non-human glycoprotein hormone having an increased activity over the wild-type human glycoprotein hormone. The invention is also directed to a method of constructing superactive nonchimeric analogs of human hormones comprising comparing the amino acid sequence of a more active homolog from another species to the human hormone, and selecting superactive analogs from the substituted human hormones. The invention is also directed to nucleic acids encoding the modified human glycoprotein hormones, vectors containing those nucleic acids, and host cells containing those vectors.
