Abstract: Multi-arm amine compounds and compositions for enhancing intracellular, in vitro, and in vivo delivery of drug, active, and therapeutic substances including ribonucleic acids. This disclosure provides novel compounds and compositions for making and using delivery materials and carriers which increase the efficiency of delivery of biologically active and pharmacologically active molecules. Embodiments of this disclosure may further provide delivery of various therapeutic agents including nucleic acid therapeutics such as regulatory RNA, interfering RNA, and agents for RNAi, as well as other protein and peptide therapeutics. In some aspects, this disclosure provides multi-arm amine compounds and compositions which can enhance permeation of a drug substance.
