  • Patent number: 5939263
    Abstract: A novel mammalian neuropeptide Y receptor and method of making the receptor are provided. The invention includes DNA encoding the receptor, the receptor, assays employing the receptor, cells expressing the receptor, antibodies which bind specifically to the receptor, RNA encoded by the DNA sequence or its complementary sequence, and single-stranded DNA with a sequence complementary to the RNA which encodes the receptor. The receptor and assays employing the receptor are useful for identifying compounds which bind to the receptor, including specific modulators of the receptor. Such compounds are useful for treating a variety of disease conditions, including obesity, diabetes, anxiety, hypertension, cocaine withdrawal, congestive heart failure, memory enhancement, cardiac and cerebral vasospasm, pheochromocytoma and ganglioneuroblastoma, and Huntington's, Alzheimer's and Parkinson's diseases.

  • Patent number: 5312753
    Abstract: Avermectin compounds are glycosylated at the 4',13- Or 14a-positions by adding the avermectin compounds to the fermentation medium of a novel strain of Streptomyces avermitilis. The 13-hydroxy and 14a-hydroxy methyl groups of the avermectin compound are glycosylated with a glycosyl moiety, specifically an oleandrose group. The new strain offers the added advantage of not producing any C5-O-methylation products. The compounds are potent anthelmintic and antiparasite agents, and compositions for such uses are also disclosed.

  • Patent number: 5252474
    Abstract: There are disclosed plasmids containing DNA isolated from Streptomyces avermitilis, the microorganism which is used to prepare avermectin compounds, identified as pAT1, pVE650 pVE855, pVE859, pVE1446, pVE923, and pVE924 which contain the genetic information for the biosynthesis of the avermectins. Methods for the isolation of such plasmid and for the manipulation of the plasmids to alter the formation of the avermectin compound are also disclosed.

  • Patent number: 5194387
    Abstract: There is disclosed a process for the incorporation of DNA into a microorganism that, because of natural restrictions in the organism, normally would prevent or limit the incorporation of the DNA. The process involves the selection of an intermediate host organism that has no restrictions to the incorporation of DNA. The DNA is then transferred into the intermediate host which is readily accomplished because there are no restrictions. The DNA is then isolated from the intermediate host and transferred into the target organism. Using this process the natural restrictions of the host organism are circumvented and DNA is transferred from a source organism to a target organism that normally would not be possible. In this manner desirable characteristics from the source organism can be imparted into the target organism.
