US Patent:

48596906, Aug 22, 1989

Filed:

Nov 21, 1986

Appl. No.:

6/934212

Inventors:

Raymond S. Chang - Lansdale PA
Otto D. Hensens - Red Bank NJ
Cheryl D. Schwartz - Westfield NJ
Deborah L. Zink - Manalapan NJ

Assignee:

Merck & Co., Inc. - Rahway NJ

International Classification:

A61K 3142

US Classification:

514375

Abstract:

Virginiamycin M. sub. 1 having the Formula: ##STR1## and virginiamycin M. sub. 1 analogs having the Formulae I-IV: ##STR2## Virginiamycin M. sub. 1 and the analogs I-IV are antagonists of cholecystokinin (CCK) and gastrin. Cholecystokinin antagonists are useful as analgesics and in the treatment and prevention of disorders of the gastrointestinal, central nervous and appetite regulatory systems in animals, especially humans. Gastrin antagonists are useful in blocking the receptors for gastrin in humans and may function as agents for the treatment of ulcers, tumors or other gastrointestinal disorders. The compounds of Formulae I-IV are also antibiotics and are useful as antimicrobial agents in animals including man and are useful as food additives to promote feed utilization in animals. Virginiamycin M. sub. 1 and the analogs of Formula I, III and IV are produced by the controlled aerobic fermentation of a strain of Streptomyces olivaceus, ATCC No. 53527.

US Patent:

Filed:

Oct 30, 1996

Appl. No.:

8/741436

Inventors:

Cheryl Faye Schwartz - Bensalem PA

Assignee:

Temple University of the Commonwealth System of Higher Education - Philadelphia PA

International Classification:

G01N 3353

US Classification:

436518

Abstract:

Solid supports for solid phase immunoassays comprise polyethyleneimine-coated negatively charged polymeric materials. The combination of negatively-charged polymer support and polyethyleneimine coating serves to eliminate nonspecific adsorption of biological molecules such as high molecular weight kininogen, which have affinity for solid surfaces and which interfere with immunoassays. The negatively charged polymeric support to which the polyethyleneimine coating is applied may advantageously comprise, for example, a carboxylate-modified styrene microparticle. Antigens or antibodies are coupled by covalent coupling agents to the polyethyleneimine coating to form solid phase immunoreagents. Immunoassays for biological molecules such as high and low molecular weight kininogen are provided.
