  • Patent number: 6121325
    Abstract: The present invention is directed to certain compounds of the general structural formula: ##STR1## wherein R.sub.1, R.sub.1a, R.sub.2a, R.sub.3, R.sub.3a, R.sub.4, R.sub.5, R.sub.6, A, W, and n are as defined herein. These compounds promote the release of growth hormone in humans and animals. This property can be utilized to promote the growth of food animals to render the production of edible meat products more efficient, and in humans, to treat physiological or medical conditions characterized by a deficiency in growth hormone secretion, such as short stature in growth hormone deficient children, and to treat medical conditions which are improved by the anabolic effects of growth hormone. Growth hormone releasing compositions containing such compounds as the active ingredient thereof are also disclosed.

  • Patent number: 6114132
    Abstract: Disclosed is a binding assay for proteases and phosphatases, which contain cysteine in their binding sites or as a necessary structural component for enzymatic binding. The sulfhydryl group of cysteine is the nucleophilic group in the enzyme's mechanistic proteolytic and hydrolytic properties. The assay can be used to determine the ability of new, unknown ligands and mixtures of compounds to competitively bind with the enzyme versus a known binding agent for the enzyme, e.g., a known enzyme inhibitor. By the use of a mutant form of the natural or native wild-type enzyme, in which serine, or another amino acid, e.g., alanine, replaces cysteine, the problem of interference from extraneous oxidizing and alkylating agents in the assay procedure is overcome. The interference arises because of oxidation or alkylation of the sulfhydryl, --SH (or --S.sup.-), in the cysteine, which then adversely affects the binding ability of the enzyme.

  • Patent number: 6111095
    Abstract: A method is provided for making synthetic capped RNAs. These compounds serve as substrates for the virally encoded endonuclease associated with influenza virus. We are able to assay for this unique and specific viral activity of cleavage of a capped RNA in vitro. Therefore, screening of inhibitors of this activity is possible. In addition, short non-extendible (due to their length or because of the modification of the 3'-end of the oligo, i.e. 3'-dA) RNAs are potent inhibitors of the cleavage of capped RNAs by influenza endonuclease. Finally, these compounds may be used to investigate viral and cellular mechanisms of transcription/translation or mRNA maturation.

  • Patent number: 6111091
    Abstract: In accordance with the present invention, there are provided nucleic acids encoding human NMDA receptor protein subunits and the proteins encoded thereby. The NMDA receptor subunits of the invention comprise components of NMDA receptors that have cation-selective channels and bind glutamate and NMDA. In one aspect of the invention, the nucleic acids encode NMDAR1 and NMDAR2 subunits of human NMDA receptors. In a preferred embodiment, the invention nucleic acids encode NMDAR1, NMDAR2A, NMDAR2B, NMDAR2C and NMDAR2D subunits of human NMDA receptors. In addition to being useful for the production of NMDA receptor subunit proteins, these nucleic acids are also useful as probes, thus enabling those skilled in the art, without undue experimentation, to identify and isolate related human receptor subunits.
