Modular dendrimers with cationic groups and lipophilic groups are provided herein. In some aspects, the dendrimers provided herein may be formulated in compositions which contain a nucleic acid and one or more helper excipients. In some aspects, these compositions may also be used to treat diseases or disorders with a therapeutic nucleic acid.

The invention relates to a derivative of a GLP-1 analogue of a general Formula I, which derivative comprises a side chain attached to a Lys residue at position 34, 35, 36, 37, or 38 of the GLP-1 analogue, which side chain comprises a Branched linker, a 1.sup.st and a 2.sup.nd Protractor selected from C18 diacid, C20 diacid, and sulfonic acid C16, and at least one Linker element-1 incorporating ethylene glycol units. Linker element-1 may be incorporated in an optional Pre-linker, and/or in a 1.sup.st or 2.sup.nd Post-linker. The invention also relates to novel GLP-1 analogues, novel side chain intermediate products and their manufacture and use to prepare derivatives of biologically active peptides and proteins, as well as pharmaceutical compositions and medical uses of the analogues and derivatives. The derivatives have very long half-lives while maintaining a satisfactory potency, which makes them potentially suitable for once-monthly administration.

A polymeric scaffold useful for conjugating with a protein based recognition-molecule (PBRM) to form a PBRM-polymer-drug conjugate is described herein. The scaffold includes one or more terminal maleimido groups. Also disclosed is a PBRM-polymer-drug conjugate prepared from the scaffold. Compositions comprising the conjugates, methods of their preparation, and methods of treating various disorders, such as cancer in a subject having low HER2 expression with the conjugates or their compositions are also described.

A gene nanocomposite and a cellular internalization method of a gene using the same are provided. More specifically provided is a gene nanocomposite including: a photosensitizer-conjugated polymer; and one or more materials selected from a gene and a gene/cationic polymer composite, and a cellular internalization method of a gene using the same to improve gene delivery efficiency into a mammal-derived cell and gene expression.

The present invention relates to micellar nanocomplexes and a method of forming the same. The micellar nanocomplex comprises a micelle and an agent encapsulated within said micelle, where the micelle comprises a polymer-flavonoid conjugate, wherein said polymer is bonded to the B ring of said flavonoid. The micellar nanocomplex may have useful applications as a drug-delivery system.

The problem addressed by the present invention is to develop a pharmaceutical having therapeutic efficacy against epirubicin-resistant tumors. The present invention provides a micelle having an anti-cancer agent disposed inside the core of the micelle formed by an epirubicin-conjugated copolymer.

The invention relates to oligofluorinated coatings and their use in drag delivery. The oligofluorinated coatings are compositions comprising formula (XVII). These coatings are used in a method of delivering a biologically active agent to a tissue surface in a mammalian tissue. This method occurs by contacting the surface with the coating including an oligofluorinated oligomer and a biologically active agent wherein the coating resides on the tissue surface and release the biologically active agent to the tissue surface.
