Abstract: The present invention is directed to a new fluoro-pyridinone hydroxamic acid phosphates and boronates of Formulae I, II and III wherein Q is selected from the group consisting of —P(O)(OH)2, —P(O)(OH)(O?M+), —P(O)(O?M+)2 and —P(O)(O?)2M2+; M+ at each occurrence is a pharmaceutically acceptable monovalent cation; and M2+ is a pharmaceutically acceptable divalent cation and their use as LpxC inhibitors and, more specifically, their use to treat bacterial infections.

Abstract: A method of control of the porosity of wells with a fibrous fluid blocking layer disposed on formation faces is provided. By means of mineral fiber pellets of critical dimensions wherein the mineral fibers are highly soluble in acid, a fluid blocking layer formed of semi-dispersed pellets can bridge formation face pores subject to removal at will by acid treatment. Thus after well rework the plugging layer is treated by an acid solution after sealing the formation faces to prevent fluid losses to quickly dissolve the mineral fibers to the desired extent for control the porosity. A novel well workover product making the method possible is formed from raw material clinkers of highly acid soluble mineral fibers of between 5 to 15 microns in diameter by grinding in a hammermill into pellets of a range of 1/32 inch to 1/2 inch in diameter with an average being between 1/16 inch to 1/8 inch and with fiber lengths between 1/64 inch to 3/8 inch.
