Transfecting compounds which include an aminoglycoside linked to a lipid via a spacer, and their polyguanidylated derivatives are provided. These compounds are useful for the in vitro, ex vivo, or in vivo transfection of nucleic acids into various cell types.
摘要:
The present invention relates to mixed calcium/sodium salt of inositol tripyrophosphate, methods of preparing and methods of use. The mixed calcium/sodium salt may be a monocalcium tetrasodium salt of inositol tripyrophosphate. Methods of use include administering the above salts in an effective amount to treat diseases caused by hypoxia or other conditions associated with inadequate function of the lungs or circulatory system, such as various types of cancer and Alzheimer's disease.
摘要:
The present invention comprises compounds, compositions thereof, and methods capable of delivering modified inositol hexaphospahte (IHP) comprising an internal pyrophosphate ring to the cytoplasm of mammalian cells. In certain embodiments, the present invention relates to compounds, compositions thereof, and methods that enhance the ability of mammalian red blood cells to deliver oxygen, by delivering IHP to the cytoplasm of the red blood cells.
摘要:
The present invention relates to compositions and methods for treating cancer and other disease states characterized by abnormal cell proliferation. In particular, the present invention relates to certain novel non-nucleoside pharmacologically active compounds that alter telomere and telomerase functions, regulate cell proliferation and/or treat cancer and other diseases characterized by abnormal cell proliferation. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit telomerase, to regulate cell proliferation, and to treat cancer or to inhibit the proliferation of the rumor cells, and to treat other proliferative conditions.
摘要:
The present invention relates to a delivery system in the form of a dynamic mixture obtained by reacting together, in the presence of water, at least one hydrazine derivative with at least one perfuming, flavoring, insect repellent or attractant, bactericide or fungicide aldehyde or ketone. The inventive mixture is capable of releasing in a controlled and prolonged manner the aldehyde or ketone in the surrounding environment. Furthermore, the present invention concerns also the use of these dynamic mixtures as perfuming ingredients as well as the perfuming compositions or perfumed articles that include such mixtures.
