  • Patent number: 10085940
    Abstract: The present disclosure provides liposomes comprising a membrane and an intraliposomal aqueous water phase, the membrane comprising at least one liposome forming lipid and the intraliposomal aqueous water phase comprises a salt of a bisphosphonate together with an amphipathic weak base agent (PLAD). An example of a liposome is one comprising co encapsulated in the intraliposomal aqueous water phase N-containing bisphosphonate, such as alendronate, and an anthracycline such as doxorubicin which was shown to increase survival as compared to Doxil or to administrations of liposomal alendronate (PLA) and Doxil (separate liposomes). Such liposomes may carry a targeting moiety exposed at the liposome's outer surface, for example, conjugate of folic acid as a targeting moiety to folate receptor (FT-PLAD). Also provided by the present disclosure is a method of preparing the liposomes and methods of use of the liposomes, at times, in combination with additional active ingredients, such as ?? T-cells.

  • Patent number: 10052387
    Abstract: Based on the observation that the application of small amounts of exogenous acid sphingomyelinase to generate endogenous ceramide, or provision of exogenous long-chain natural C16-ceramide resulted in rapid translocation of vacuolar daunorubicin into the nucleus in multi-drug resistant (MDR) cells, the present invention relates to a nano-liposomal preparation that includes C16-ceramide. Exposure of MDR cells to the C16:0 ceramide-based nanoliposomes provide a mechanism to reverse MDR in chemoresistant cells and tumors, by inducing rapid translocation of chemotherapeutic agent from cytoplasmic vesicles to the nucleus.
