摘要:
Compounds inhibiting phosphatidylinositol 3-kinase (PI 3-K) activities and methods of preparing and using thereof in treating diseases are disclosed. Compounds inhibiting PI 3-K activity and methods of using PI 3-K inhibitory compounds to inhibit cancer cell grwoth or to treat disorders of immunity and inflammation, in which PI 3-K plays a role in leukocyte function are also provided.
摘要:
The methods and compositions disclosed herein concern the synthesis of a novel class of “two-headed” phospholipid-phosphoinositide hybrids possessing a carbon backbone, such as 2,3-diacylthreitol, erythritol or a synthetic module. The second phospholipid head group allows introduction of a biochemical or chemical moiety in a position orthogonal in space to those occupied by the phosphoinositide head group and the two acyl chains. The diacyl moieties allow for the incorporation of Pea-PIP2 into a lipid bilayer, while the Ptdlns(4,5)P2 moiety in the aqueous layer is specifically recognized by lipid binding proteins. In alternative embodiments of the invention, reporters, for example biotin, fluorophores and/or spin labels, are attached to the free amino group of the head groups of such molecules to specifically target the reporters to the lipid-water interface.

摘要:
Fluorogenic lysophosphatidic acid derivatives which can be used as substrates in a continuous, fluorogenic assay that can be performed in microtiter plates. The assays permit measuring LysoPLD activity levels in normal events such as pregnancy or disease states such as cancer. In addition, the present invention can be adopted to high throughout screening (HTS) for identification of potential inhibitors of lysoPLD activity.

摘要:
A controller equipped with a user interface having multiple-day programming capabilities, including methods of programming such devices, are disclosed. The user interface may include one or more menus or screens that can be used to program a schedule for one or more selected days during the week. An illustrative method of programming the controller may include the steps of entering a scheduling routine, selecting multiple days for schedule modification, changing the schedule parameters for one or more periods during the selected days, and then exiting the scheduling routine.
