  • Patent number: 5240915
    Abstract: There are disclosed avermectin derivatives which are avermectin modified at the 3- and 4-positions. The 3-hydroxy and 4-keto, epoxide and hydroxy (hydroxymethyl) derivatives and the 4-oxo compound are prepared from the natural avermectin by moving the 3,4-double bond exocyclic at 4 and forming a 3-hydroxy group. Osmolation gave an .alpha.,.beta.-diol across the double bond and cleavage of the diol provided the 4-oxo compound. The 4-oxo compound is epoxidized with an ylide reagent. The compounds are useful as anthelmintic agents and compositions for that use using the compounds as the active ingredient thereof are also described.

  • Patent number: 5232830
    Abstract: Novel methods and compositions for detecting a member of a ligand pair on solid supports having intrinsic fluorescence are disclosed. A target member of a ligand pair is contacted with a capture member of a ligand pair, wherein the capture member is immobilized on a solid support having intrinsic fluorescence, and the contacted pair is in association with a colorimetric reporter, then the solid support is irradiated the solid support, and the resultant fluorescence is determined. Preferably, methods include hybridization assays of nucleic acid sequences on such solid supports. The extent of detecting a member of a ligand pair, preferably a nucleic acid sequence, is determined using a method or technique described throughout this document as fluorescent quenching. Methods and compositions pertaining to solid supports having their intrinsic or natural fluorescence quenched or masked are also described herein. The present invention has utility in detection assays for a member of a ligand pair.
