Hydrotropic dendrimers of generations 4 and 5: synthesis, characterization, and hydrotropic solubilization of paclitaxel.
Polyglycerol dendrimers (PGDs) with 4-5 generations were synthesized and used to investigate the effect of dendritic architecture and its generation on aqueous solubilization of paclitaxel (PTX), a poorly water-soluble drug. Chemical and physical properties of the PGDs were characterized by NMR, MALDI-TOF mass, GPC, viscosity, and dynamic light scattering measurements. The PTX solubility in all...
متن کاملHydrotropic polymer micelle system for delivery of paclitaxel.
Hydrotropic polymer micelle system has been developed for delivery of poorly water-soluble drugs such as paclitaxel. Hydrotropic polymers based on N,N-diethylnicotinamide were synthesized and used as a hydrophobic block for constructing amphiphilic block copolymers. The hydrotropic block copolymers self-assembled to form micelles in aqueous media. The size of the prepared polymer micelles was i...
متن کاملA new hydrotropic block copolymer micelle system for aqueous solubilization of paclitaxel.
Paclitaxel (PTX), a potent anti-cancer drug, is poorly soluble in water, and this has been a major limitation in developing patient friendly formulations for clinical applications. Recent studies on polymeric micelles, especially hydrotropic polymer micelles, have suggested an alternative formulation of PTX based on their high loading capacity and physical stability in aqueous media. The presen...
متن کاملHydrotropic solubilization of poorly water-soluble drugs.
The solubilizing ability of two aromatic hydrotropes, N,N-diethylnicotinamide (DENA) and N,N-dimethylbenzamide (DMBA), was investigated using a set of 13 poorly soluble, structurally diverse drugs. The number of aromatic rings in the solute molecule has a very strong effect on the solubility enhancement produced by either hydrotrope. However, although solubility enhancements in the order of 100...
متن کاملHydrotropic hyaluronic acid conjugates: Synthesis, characterization, and implications as a carrier of paclitaxel.
Amphiphilic hyaluronic acid conjugates were synthesized as a potential drug carrier by chemical conjugation of an amine-terminated hydrotropic oligomer, which has a unique ability to enhance the solubility of paclitaxel (PTX), to a hyaluronic acid (HA) backbone using carbodiimide chemistry. The physicochemical properties of the hydrotropic hyaluronic acid (HydroHA) conjugates were investigated ...
