This study presents PKSolver, a freely available menu-driven add-in program for Microsoft Excel written in Visual Basic for Applications (VBA), for solving basic problems in pharmacokinetic (PK) and pharmacodynamic (PD) data analysis. The program provides a range of modules for PK and PD analysis including noncompartmental analysis (NCA), compartmental(More)
In recent years, several mathematical models have been developed for analysis of drug dissolution data, and many different mathematical approaches have been proposed to assess the similarity between two drug dissolution profiles. However, until now, no computer program has been reported for simplifying the calculations involved in the modeling and(More)
In this study, a ligand-PEG-lipid conjugate, octreotide-polyethene glycol-deoxycholic acid (OCT(Phe)-PEG-DOCA, or OPD) was successfully synthesized and used as a targeting molecule for N-deoxycholic acid-O, N-hydroxyethylation chitosan (DAHC) micelles for efficient cancer therapy. DAHC micelles exhibited good loading capacities for doxorubicin (DOX), a(More)
A new series of amphiphilically modified chitosan molecules with long alkyl chains as hydrophobic moieties and glycol groups as hydrophilic moieties (N-octyl-O-glycol chitosan, OGC) was synthesized for use as drug carriers. The chemical structure was characterized by Fourier transform infrared, (1)H nuclear magnetic resonance, and elemental analysis. OGC(More)
The overall goal of this study was to develop a micellar system of paclitaxel (PTX) to enhance its oral absorption. An amphiphilic chitosan derivative, N-deoxycholic acid-N, O-hydroxyethyl chitosan (DHC), was synthesized and characterized by FTIR, (1)H NMR, elemental analysis, and X-ray diffraction (XRD) techniques. The degree of substitution (DS) of(More)
Among the materials for preparing the polymeric nanocarriers, poly(n-butylcyanoacrylate) (PBCA), a polymer with medium length alkyl side chain, is of lower toxicity and proper degradation time. Therefore, PBCA has recently been regarded as a kind of widely used, biocompatible, biodegradable, low-toxic drug carrier. This review highlights the use of(More)
Octreotide (OCT) was recently found to have high binding affinity to the positive tumor cells of somatostatin receptors (SSTRs). In this study, octreotide-Phe-polyethylene glycol-stearic acid was first successfully synthesized and used as a targeting molecule for N-octyl-O, N-carboxymethyl chitosan (OCC). Doxorubicin (DOX) was loaded into OCT-modified OCC(More)
A targeted intracellular delivery system of paclitaxel (PTX) was successfully developed based on redox-sensitive hyaluronic acid-deoxycholic acid (HA-ss-DOCA) conjugates. The conjugates self-assembled into nano-size micelles in aqueous media and exhibited excellent drug-loading capacities (34.1%) and entrapment efficiency (93.2%) for PTX. HA-ss-DOCA(More)
A novel albumin derivative octyl modified serum albumin (OSA) which can form a core-shell structure in aqueous media by self-assembling due to core segregation and a combination of intermolecular forces has been synthesized. The chemical structure and physical properties of OSA were characterized by FTIR, (1)H NMR and TG. The degree of substitution (DS) was(More)
In this study, a novel redox-sensitive micellar system constructed from a hyaluronic acid-based amphiphilic conjugate (HA-ss-(OA-g-bPEI), HSOP) was successfully developed for tumor-targeted co-delivery of paclitaxel (PTX) and AURKA specific siRNA (si-AURKA). HSOP exhibited excellent loading capacities for both PTX and siRNA with adjustable dosing ratios and(More)
