Patent number: 5015729Abstract: 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-Pr o- 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.Type: GrantFiled: June 23, 1988Date of Patent: May 14, 1991Assignee: The Salk Institute for Biological StudiesInventors: Joachim Spiess, Jean E.

The peptides have the structure:X-R.sub.1 -(W)D-Phe-R.sub.3 -R.sub.4 -R.sub.5 -R.sub.6 -R.sub.7 -Arg-Pro-R.sub.10wherein X is hydrogen or an acyl group having 7 or less carbon atoms; R.sub.1 is dehydro-Pro, D-pGlu, D-Phe, D-Trp of .beta.-D-NAL; W is F, Cl, Cl.sub.2 Br, NO.sub.2 or C.sup..alpha. Me-Cl; R.sub.3 is (N.sup.in For)D-Trp or D-Trp which is substituted in the 5- or 6-position with NO.sub.2, NH.sub.2, OCH.sub.3, F, Cl, Br or CH.sub.3 ; R.sub.4 is Ser, Orn, AAL or aBu; R.sub.5 is Tyr, Arg, (3F)Phe, (2F)Phe, (3I)Tyr, (3CH.sub.3)Phe, (2CH.sub.3)Phe, (3Cl)Phe or (2Cl)Phe; R.sub.6 is (4NH.sub.2)D-Phe, D-Lys, D-Orn, D-Har, D-His, (4gua)D-Phe, D-Tyr, a D-isomer of a lipophilic amino or D-Arg; R.sub.7 is Leu, NML, Nle or Nva; and R.sub.10 is Gly-NH.sub.Type: GrantFiled: May 21, 1984Date of Patent: February 11, 1986Assignee: The Salk Institute For Biological StudiesInventors: Jean E.
