  • Patent number: 11938226
    Abstract: The present invention relates generally to compositions and methods comprising abiotic, synthetic polymers with affinity and specificity to proteins. The synthetic polymers are an improvement over biological agents by providing a simpler, less expensive, and customizable platform for binding to proteins. In one embodiment, the compositions and methods relate to synthetic polymers with affinity and specificity to vascular endothelial growth factor (VEGF). In one embodiment, the compositions are useful for treating diseases and disorders related to the overexpression of VEGF. In one embodiment, the compositions are useful for treating cancer. In one embodiment, the compositions are useful for detecting VEGF levels from biological samples. In one embodiment, the compositions are useful for detecting overexpression of VEGF from biological samples. In one embodiment, the compositions are used to diagnose cancer.

  • Patent number: 11034708
    Abstract: An object is to provide a lipid particle that is not positively charged at a pH of the body fluid (typically in the neutral range), and that enables efficient onset of the effect of a medicinal substance encapsulated in the lipid particle; and to provide a lipid for forming the lipid particle. The object is achieved by the phospholipid represented by formula (1), and a lipid particle containing the phospholipid: wherein R1 and R2 are identical or different, and represent a chain hydrocarbon group, m represents 1 or 2, n represents 1 or 2, and p represents an integer of 1 to 4.

  • Publication number: 20150157610
    Abstract: A pharmaceutical composition which comprises, as an active ingredient, a liposome encapsulating an immunosuppressant such as FK506, FTY720 and cyclosporin A is effective in the treatment of cardiovascular inflammatory diseases such as my ocardial infarction, myocarditis and vasculitis syndrome, allows the immunosuppressant at a low dose to produce stronger effects than those of the same dose of the immunosuppressant used alone, and causes fewer side effects.
