  • Patent number: 11447515
    Abstract: The present invention relates to triterpene glycoside saponin-derived adjuvants, syntheses thereof, intermediates thereto, and uses thereof. QS-7 is a potent immuno-adjuvant that is significantly less toxic than QS-21, a related saponin that is currently the favored adjuvant in anticancer and antiviral vaccines. Tedious isolation and purification protocols have hindered the clinical development of QS-7. A novel semi-synthetic method is provided wherein a hydrolyzed prosapogenin mixture is used to synthesize QS-7, QS-21, and related analogs, greatly facilitating access to QS-7 and QS-21 analogs for preclinical and clinical evaluation.

  • Patent number: 11441118
    Abstract: The present invention provides compositions and methods for transferring phospholipids and other molecules between the leaflets of a cell membrane. The compositions comprise at least one nucleic acid or compound having a hydrophilic region, where the composition is able to form a nanostructure that forms a toroidal pore in a lipid membrane. The nucleic acid or hydrophilic region-containing compound further contains an attached molecule capable of inserting the nanostructure into the lipid membrane. The invention also provides methods for scrambling lipids and other molecules in a cell membrane, which can be used to alter the function of a selected cell or to facilitate the death of the cell. The scrambling activity of synthetic scramblases described herein outperforms previously known enzymatically active DNA nanostructures and naturally occurring scramblases, in some cases by several orders of magnitude.

  • Patent number: 11396523
    Abstract: The present application provides compositions and methods for preparing and using “heavy” nucleotide derivatives of thymidine or uridine by replacing the oxygen atom attached to one or more of positions with non-radioactive oxygen-18 (18O), administering it to a subject to target a tumor including incorporation into tumor cell DNA, and then treating the tumor with proton beam therapy to transmutate the 18O to 18F, resulting in a break of the new fluorine-phosphorous bond. This chemical event destabilizes ribose-phosphate DNA back-bone and base pairing thus produce single- and double strand breaks, clusters lesions that can lead to irreparable DNA damage and enhanced tumor cell killing. The atomic, chemical, and physical aspects result in the use of lower radiation doses and significantly alter acute and late morbidity of radiotherapy. Heavy thymidine and heavy uridine derivatives labeled with 18O have been made and tested.
