Patent number: 6783761Abstract: Chimeric peptide epitopes can serve as effective immunogens against hormones and other small peptides or proteins. Thus, immunogenic peptides are selected from promiscuous Th epitopes and synthesized together with self antigenic peptide sequences fused with or without end to end spacer peptide interconnections. A peptide sequence which may be of the gonadotropin releasing hormone is linked with an immunogenic peptide sequence selected from a promiscuous Th-epitope of measles virus protein F, tetanus toxoid, or malaria protein CSP. Compositions of the chimeric immunogen are found effective in eliciting high and specific anti-GnRH antibody titers.Type: GrantFiled: May 4, 2001Date of Patent: August 31, 2004Assignee: Aphton CorporationInventors: Stephen Grimes, Dov Michaeli, Vernon C. Stevens

Patent number: 6716428Abstract: Endogenous protein hormones, fragments thereof including epitopes, and synthetic peptides mimicking epitope regions of hormones such as human chorionic gonadotropin can be conjugated to a foreign carrier or otherwise modified so as to produce antibodies in humans against the endogenous protein hormone. Synthetic analogs to the 38 to 57 sequence of the beta subunit of human chorionic gonadotropin have been found which upon conjugation to a suitable foreign carrier can be employed to raise a high level of antibodies to human chorionic gonadotropin with a significant decrease in antibodies reactive to human pituitary luteinizing hormones. Upon conjugation to a foreign carrier such analogs may be administered to humans to treat hormone-associated carcinomas and for purposes of contraception.Type: GrantFiled: October 6, 1999Date of Patent: April 6, 2004Assignee: The Ohio State University Research FoundationInventor: Vernon C.

Patent number: 6217881Abstract: Endogenous and exogenous proteins, and fragments thereof, are chemically modified outside the body of an animal so that when injected into the animal they produce more antibodies against the unmodified protein than would injection of the unmodified protein or fragment alone. The chemical modification may be accomplished by attaching the proteins or fragments to carriers such as, for example, bacterial toxoids. The chemical modification can also be accomplished by polymerization of protein fragments. Proteins which can be modified include Follicle Stimulating Hormone and Human Chorionic Gonadotropin. The modified polypeptides may be administered to animals for the purpose of contraception, abortion or treatment of hormone-related disease states and disease disorders, treatment of hormone-associated carcinomas, and to boost the animals resistance to exogenous proteins, for example viral proteins.Type: GrantFiled: June 6, 1995Date of Patent: April 17, 2001Assignee: The Ohio State University Research FoundationInventor: Vernon C.

Patent number: 4526716Abstract: Modified hormones or fragments of hormones are useful in producing antibodies when administered to an animal. Said antibodies in turn cause neutralization of endogenous natural protein hormones. Also, non-endogenous proteins or peptides (for example viral proteins or fragments thereof) can be modified to increase an animal's immune response thereto. These modification may be accomplished by attaching various kinds of modifying groups to the hormone or fragment. Modification may, for example, be achieved by chemically coupling diazosulfanilic acid groups to the hormone or fragment. The protein hormones to which this procedure can be applied are mammalian protein reproductive hormones such as, for example, Follicle Stimulating Hormone (FSH), or Human Chorionic Gonadotropin (HCG). These modified polypeptides may be administered to animals for the purpose of contraception, abortion, or treatment of hormone-related disease states and disorders, including hormone-associated carcinomas.Type: GrantFiled: March 4, 1983Date of Patent: July 2, 1985Assignee: The Ohio State UniversityInventor: Vernon C.
