摘要： A dimeric protein with inhibin activity is isolated from ram reta testis fluid using reverse-phase high-performance liquid chromatography and gel filtration. The isolated molecule is composed of two chains having apparent molecular weights of about 18,000 and about 16,500 to 14,500 Daltons, as measured by gel electrophoresis, which are bound together by disulfide bonding and the longer of which is likely glycosylated. Microsequencing revealed the NH.sub.2 -terminal portion of the longer chain to be Ser- Thr-Pro-Pro-Leu-Pro-Trp-Pro-Trp-Ser-Pro-Ala-Ala-Leu-Arg-Leu-Gln-Arg-Pro-Pro- Glu-Glu-Pro-Ala-Ala-His-Ala-Asp-Cys and of the shorther chain to by Gly-Leu-Glu-Cys-Asp-Gly-Lys-Val-Asn-Ile-Cys-Cys-Lys-Lys-Gln-Phe. This dimeric protein specifically inhibits basal secretion of FSH, but not of LH, in a rat anterior pituitary monolayer culture system, exhibiting a half-maximal effective dose of about 0.1 to 0.3 ng/ml. Furthermore, antibodies raised against synthetic replicates of the N-terminal six residues of the longer chain, as well as against the N-terminal 25 residues, are effective to reduce the activity of highly purified intact ovine inhibin and might be used to exert a profertility effect in rams, ewes and other mammals.

摘要： A 28,000-dalton protein with FSH-releasing activity is isolated from porcine follicular fluid in a multi-step procedure including gel filtration, ion exchange chromatography and several reverse-phase high-performance liquid chromatography steps. The 28 kD protein promotes secretion of FSH, but not of LH, in a rat anterior pituitary monolayer culture system, exhibiting an EC.sub.50 of 0.5 ng/ml. These peptides are dimers of inhibin .beta.-chains of mammals, and homodimers or heterodimers of the .beta..sub.A and .beta..sub.B chains are biologically active to regulate fertility of various mammalian species, including humans.

The invention provides synthetic peptides which are extremely potent in stimulating the release of pituitary GH in mammals and which have the formula: H-Tyr-Ala-Asp-Ala-Ile-Phe-Thr-Asn-Ser-Tyr-Arg-Lys-Val-Leu-R.sub.15 -Gln-Leu-Ser-Ala-Arg-Lys-Leu-Leu-Gln-Asp-Ile-Met-Ser-Arg-Gln-Gln-Gly-Glu-Ser-Asn-Gln-Glu-Arg-Gly-R.sub.40 -R.sub.41 -R.sub.42 -Y wherein R.sub.15 is Gly or D-Ala, R.sub.40 is Ala or des-R.sub.40, R.sub.41 is Phe or des-R.sub.41, R.sub.42 is des-R.sub.42 or 1 to 8 different amino acid residues selected from the group consisting of Gln, Gly, Ile, Leu, Lys, Pro, Thr and Val, and Y signifies the carboxyl moiety of the amino acid residue at the C-terminal and is the radical -COOR.sub.1,-CR.sub.1 O,-CONHNHR.sub.1,-CON(R.sub.1)(R.sub.2) or -CH.sub.2 OR.sub.1, with R.sub.1 and R.sub.2 being lower alkyl or hydrogen. These peptides or biologically active fragments thereof, or analogs thereof having well-known substitutions and/or additions, as well as nontoxic salts of any of the foregoing, may be administered therapeutically to animals, including humans, and may be used diagnostically.
