Recently, we synthesized novel amphiphilic gelatin–oleic acid (GO) conjugate to prepare self-assembled nanoparticles for drug delivery. The aim of this study was to investigate pharmaceutical potentialities of self-assembled GO nanoparticles for solubility enhancement and modified release of poorly water-soluble drugs. Three poorly water-soluble model drugs with different pH-dependent solubility (valsartan and aceclofenac, insoluble at pH 1.2; telmisartan, insoluble at pH 6.8) were chosen to investigate the potential contributions of self-assembled GO nanoparticles to solubility enhancement and controlled release. The particle size of the drug-loaded nanoparticles was 200–250 nm. Zeta potential was calculated, and instrumental analysis such as powder X-ray diffraction (PXRD) and Fourier transform infrared (FT-IR) spectroscopy were used to investigate the physicochemical properties of the drug-loaded nanoparticles. Compared to the drug alone, the drug-loaded nanoparticles showed enhanced solubility. Furthermore, the release profiles of the model drugs were modified in a controlled manner. The current self-assembled GO nanoparticles can provide a versatile potential in drug delivery and tumor targeting.
