Abstract: Disclosed are branched PEG molecules, including branched PEG-lipids and branched-PEG proteins, as well as related compositions and methods for making branched PEG molecules. Also disclosed are related compositions, systems, and methods for in vivo delivery of therapeutic and diagnostic agents.

Abstract: Described herein are block copolymers, and methods of making and utilizing such copolymers. The described block copolymers are disruptive of a cellular membrane, including an extracellular membrane, an intracellular membrane, a vesicle, an organelle, an endosome, a liposome, or a red blood cell. Preferably, in certain instances, the block copolymer disrupts the membrane and enters the intracellular environment. In specific examples, the block copolymer is endosomolytic and capable of delivering an oligonucleotide (e.g., an mRNA) to a cell. Compositions comprising a block copolymer and an oligonucleotide (e.g., an mRNA) are also disclosed.

Abstract: Lipopeptide compounds comprising a peptide having 2 to 100 amino acid residues, and having a lipophilic group attached to at least one terminus of the peptide or to at least one amino acid residue of the peptide, and salts and uses thereof. The lipophilic group may be attached to the N-terminus, C-terminus or both termini of the peptide. The lipophilic group may be attached to at least one interal amino acid residue (i.e., an amino acid residue that is not the N-terminus or the C-terminus amino acid residue of the peptide). The lipophilic group may be attached to either termini or both and at least one internal amino acid residue.

Abstract: Compounds and components including sequences for mucosal epithelial transport of an active agent are given. Tight junction modulating peptide components are described for use in transport and delivery. Permeability can be enhanced with reversibility. Compounds and components for enhanced delivery may be peptide or protein variants, conjugates, or other analog types and structures.

Abstract: A double-stranded RNA, preferably a small, interfering (si)RNA or a siHybrid, to which cholesterol moieties are linked.

Abstract: Dicer substrate RNA peptide conjugates comprising a double stranded ribonucleic acid (dsRNA) having a sense strand and an antisense strand, and a peptide, wherein the dicer substrate RNA is conjugated to the peptide, and compositions and methods of use thereof.

Abstract: What is described is a composition for delivery of a RNA molecule to a cell, comprising: a double stranded RNA (dsRNA) molecule of about 15 to about 40 base pairs; and a polynucleotide delivery-enhancing peptide, comprising a region of alternating lysine and histidine residues, or of alternating D and L forms of arginine.

Abstract: Disclosed are novel carboxylate salts of galantamine including galantamine gluconate, galantamine lactate, galantamine citrate and galantamine glucarate. These salts of galantamine have more than a 5 fold increase in solubility compared to galantamine hydrobromide. These galantamine salts can be administered to an individual to inhibit acetylcholinesterase in the treatment of such diseases as Alzheimer's disease, atony of the smooth muscle of the intestinal tract and urinary bladder, glaucoma, myasthenia gravis, and termination of the effects of competitive neuromuscular blocking drugs.

Abstract: This invention relates to the use of a coiled-coil structural scaffold to generate structure-specific peptides, including synthetic peptides derived from naturally occurring proteins of various origin. The structure of the synthetic peptides utilizes a scaffold of heptad repeat units into which epitopes from coiled-coil regions of native proteins are spliced. In particular, the synthetic peptides may be based on microbial proteins, especially surface proteins, which occur naturally in the coiled-coil form such as pneumococcal surface proteins A and C. The synthetic peptides are immunogenic and can be used to elicit an immune response in an animal. Accordingly, they are useful as vaccines or to stimulate antibody production or cell-mediated immunity to the naturally occurring protein.
