  • Patent number: 11155527
    Abstract: Macromolecules comprising triazoles and related compositions and methods are provided. In some embodiments, a macromolecule may comprise one or more repeat units including a triazole and a functionalizable pendant group. The macromolecule may also comprise one or more orthogonally addressable end groups. In some embodiments, one or more repeat units may be formed by a synthetic process that allows for precise control over stereochemistry, pendant functionality, and/or the spatial relationship (e.g., distance) between groups in the repeat unit(s). Such precise control over pendant group and repeat unit structure allows for the macromolecule functionality, stereochemistry, and spacing between groups (e.g., pendant groups) to be precisely controlled. Macromolecules described herein may be used for a wide variety of applications, including the delivery of active agents.

  • Publication number: 20210317143
    Abstract: Disclosed herein are compounds of Formula (I) or (II). The compounds include an agent (e.g., pharmaceutical agent, cosmetic agent, or nutraceutical agent) through a linker that includes a boronic ester moiety in the backbone of the linker. The compounds may be monomers. Also provided are polymers prepared by polymerizing the monomers. The polymers may be useful for delivering the agent to a subject, tissue, biological sample, or a cell. Also provided are methods of preparing the polymers, compositions and kits comprising the polymers, and methods of use (e.g., use in delivering the agent, treating a disease, preventing a disease, diagnosing a disease) involving the polymers or compositions. The structure of the boronic ester moiety may be fine tuned so that the properties related to delivery to a subject, biological sample, tissue, or cell may be fine tuned.
