Patent CA-2988893-A1 (CA)
Inventor: MILLER MATTHEW L
IPC: E21B33/138
Filed: 2013-07-29
Abstract: Compositions for lost circulation materials (LCM) and methods for using same in drilling and/or completing wellbores that help solve lost circulation problems in a wide range of fracture sizes, thereby advantageously eliminating the need for a variety of products for lost circulation in a field at any one time. An unexpected synergy and improved reduction in lost circulation is obtained. The invention provides specific LCM  components in specific ratios that are analogs to lost circulation fractures and that yield superior performance in preventing or alleviating lost circulation in drilling and cementing boreholes.  The invention compositions have a multi-modal particle size distribution (PSD) which provides a higher concentration of component materials in the same range of two or more fracture widths, thus allowing plugging to occur over a wider range than a single mode or narrow PSD.

Title: Peripheral modifications on pocket-redesigned vancomycin analogs synergistically improve antimicrobial potency and durability
Inventor: BOGER DALE L
IPC: C07K7/54
Filed: 2017-10-31
Abstract: A C-terminus modification to a binding pocket-modified vancomycin introduces a quaternary ammonium salt that provides a binding pocket-modified vancomycin analog with a second mechanism of action that is independent of D-Ala-D-Ala/D-Ala-D-Lac binding. The modification disrupts cell wall integrity and induces cell wall permeability complementary to the glycopeptide inhibition of cell wall synthesis, and provides synergistic improvements in antimicrobial potency (200-fold) against vancomycin-resistant bacteria. Combining the C- terminus and binding pocket modifications with an orthogonal (4-chlorobiphenyl ) methyl addition to the vancomycin disaccharide provides even more potent antimicrobial agents whose activity can be attributed to three independent and synergistic mechanisms of action, only one of which requires D-Ala-D-Ala/D-Ala- D-Lac binding. The resulting modified vancomycins display little propensity for acquired resistance through serial exposure of vancomycin-resistant Enterococci and their durability against such challenges as well as their antimicrobial potency follow predicable trends. Methods of treatment with and compositions containing the modified vancomycins are disclosed.
