Abstract
For developing a multifunctional bioreducible targeted and synergistic co-delivery system for anticancer drug paclitaxel (PTX) and p53 gene for potential cancer therapy, supramolecular self-assembled inclusion complex was prepared from PTX and star-shaped cationic polymer containing γ-cyclodextrin (γ-CD) and multiple oligoethylenimine (OEI) arms with folic acid (FA) conjugated via a disulfide linker. The inclusion complex, termed as γ-CD-OEI-SS-FA/PTX, was formed between PTX and the hydrophobic cavity of γ-CD core of the star polymer. The γ-CD-OEI-SS-FA/PTX complex further formed polyplexes with pDNA to give positively charged nanoparticles, becoming multifunctional supramolecular self-assembled co-delivery system for PTX and pDNA targeting to cancer cells that overexpress folate receptors (FRs). The results showed that the FA-targeted function induced higher gene transfection efficiency in the FR-positive KB cells. The redox-sensitive disulfide linker in the self-assembly system led to the detachment of the FA groups from the carrier after the FR-mediated endocytosis, which resulted in the release of the bound FRs followed by the recycling of the FRs from the cytosol onto the cell membrane surface, facilitating continuous FR-mediated endocytosis to achieve enhanced gene transfection. In addition, the complexed PTX was co-delivered to the cells with pDNA, which further enhanced the gene transfection even at low N/P ratios in the FR-positive KB cells. Further, the efficient delivery of wild-type p53 gene resulted in large cell population at sub G1 and G2/M phases, inducing significant cell apoptosis. Therefore, the multifunctional γ-CD-OEI-SS-FA/PTX self-assembly system with the synergistic effects of redox-sensitive FA-targeted and PTX-enhanced p53 gene delivery may be promising for cancer therapeutic application.

Abstract
A biotinylated paclitaxel derivative with an extra-long-chain (LC-LC-Biotin) spacer arm was synthesized using an improved synthetic reaction sequence. The biotinylated paclitaxel analogue retained excellent microtubule stabilizing activity in vitro. Furthermore, it was shown that this analogue can simultaneously engage streptavidin and the binding site on microtubules, making it suitable for localization studies or for the attachment of paclitaxel to solid substrates via a streptavidin linkage.

Abstract
Three different variants of photoactivatable caged paclitaxel (PTX) have been synthesized and their bioactivity was characterized in in vitro assays and in living cells. The caged PTXs contain the photoremovable chromophore 4,5-dimethoxy-2-nitrobenzyloxycarbonyl (Nvoc) attached to position C7, C2' and to both of these positions via a carbonate bond. Single caged PTXs remained biologically active even at low dosages. Double caging was necessary in order to fully inhibit its activity and to obtain a phototriggerable PTX that can be applied successfully at commonly used concentrations. Irradiation of solutions containing the double caged PTX allowed dose-dependent delivery of functional PTX. Light-triggered stabilization of microtubule assemblies in vitro and in vivo by controlled light exposure of tubulin solutions or cell cultures containing caged PTX was demonstrated. Short light exposure under a fluorescence microscope allowed controlled delivery of free PTX during imaging.

Abstract
Anti-HER2 monoclonal antibody (Sc7301)-paclitaxel (TAX) immunoconjugate was prepared and its specific binding to tumor cells was investigated in this study. Sc7301 was conjugated to TAX by the active ester method and then the TAX-Sc7301 immunoconjugate was obtained. After purification and labeling by Cyano-fluorescein isothiocyanate (FITC), the specific binding of TAX-Sc7301 to HER2-positive tumor cells (SKOV3) and HER2-negative tumor cells (HepG2) was evaluated respectively. TAX-Sc7301 (20 nmol/L) showed distinct specific binding to SKOV3 cells rather than HepG2 cells. And the uptake of the immunoconjugate by SKOV3 cells was increased with the TAX-Sc7301 concentration (3-48 nmol/L) and the incubation time (P<0.05). It was concluded that the TAX-Sc7301 immunoconjugate is potentially applicable as a targeted agent against HER2-positive tumor cells.

A conformationally-biased, response-selective agonist of C5a acts as a molecular adjuvant by modulating antigen processing and presentation activities of human dendritic cells. Int Immunopharmacol 2008; 8:819-27.

Abstract
A partial mechanism by which a conformationally-biased, response-selective agonist of complement component C5a, Tyr-Ser-Phe-Lys-Pro-Met-Pro-Leu-D-Ala-Arg or YSFKPMPLaR (EP54), acts as a molecular adjuvant is presented by showing the manner in which this peptide engages human dendritic cells (DC). Confocal microscopy was used to show that fluorescent-labeled EP54 (0.2 microM) and fluorescent-labeled B and T cell epitopes attached to EP54 (i.e., EP54-containing vaccines, 0.2 microM) were internalized by human DCs well within 30 min of exposure. After 24 h of exposure, EP54 and the B and T cell epitopes of the EP54-containing vaccines (20 microM) were presented on the DC surface in the context of HLA-ABC and HLA-DR determinants. Also, exposure of DCs to EP54 (50 microg/ml) induced the activation of genes specific for the Th1 cytokines IL-6, IL-12, INFgamma, and TNFalpha as well as the Th2 cytokine IL-4. Internalization, HLA expression, and cytokine gene activation were not observed in the presence of the inactive, scrambled EP54 constructs arguing that these effects of EP54 are mediated predominately via C5a receptors on the DC surface.

Abstract
Paclitaxel (1a), a well known antitumor agent adopted mainly for the treatment of breast and ovarian cancer, suffers from significant disadvantages such as low solubility, certain toxicity and specific drug-resistance of some tumor cells. To overcome these problems extensive research has been carried out. Among the various proposed strategies, the conjugation of paclitaxel (1a) to a biocompatible polymer, such as hyaluronic acid (HA, 2), has also been considered. Coupling a bioactive compound to a biocompatible polymer offers, in general, many advantages such as better drug solubilization, better stabilization, specific localization and controlled release. Hereafter the design, synthesis and applications of hyaluronic acid-paclitaxel bioconjugates are reviewed. An overview of HA-paclitaxel combinations is also given.

Abstract
A surface coating based on polylysine/hyaluronic acid multilayers was designed and acted as a reservoir for an antiproliferative agent, paclitaxel (Taxol). Absolutely no chemical modification of polyelectrolytes or of the drug was needed and the final architecture was obtained in an extremely simple way using the layer-by-layer method. The paclitaxel dose available for human colonic adenocarcinoma cells HT29 seeded on the films could be finely tuned. Moreover, the accessibility of the drugs was controlled by adding on the top of the drug reservoir a capping made of synthetic polyelectrolyte multilayers. This capping was also required to allow adhesion of HT29 cells. Paclitaxel activity was maintained after embedding in the polyelectrolyte multilayers and cellular viability could be reduced by about 80% 96 h after seeding. The strategy described in this paper could be valuable for various other drug/cell systems.

Abstract
Paclitaxel and oxaliplatin are promising drugs for combination trials but both induce peripheral neurotoxicity. To investigate this toxicity, 10-week-old female Wistar rats were given single intraperitoneal doses of paclitaxel and oxaliplatin, alone or in combination. Neurotoxicity was assessed by L5 dorsal root ganglion morphometry and H-reflex-related sensory nerve conduction velocity. Platinum concentrations in dorsal root ganglia and plasma were measured by inductively coupled plasma mass spectrometry. Dorsal root ganglion nucleolus size was significantly increased following single doses of paclitaxel of 10 and 20 mg kg(-1) at 24 h and 6 days (P<0.02). In contrast, dorsal root ganglion nucleolus size was significantly decreased following single doses of oxaliplatin ranging from 3 to 30 mg kg(-1) at time points ranging from 2 h to 14 days. Sensory nerve conduction velocity was altered after a single dose of oxaliplatin but not after paclitaxel. In combination with oxaliplatin, paclitaxel did not alter the plasma pharmacokinetics or dorsal root ganglion accumulation of oxaliplatin-derived platinum. However, prior paclitaxel inhibited oxaliplatin-induced reductions of dorsal root ganglion nucleolar diameter (P<0.02). Sensory nerve conduction velocity was reduced after oxaliplatin alone (P&<0.05) but unchanged when paclitaxel was given before oxaliplatin. In conclusion, paclitaxel induces nucleolar enlargement in dorsal root ganglion neurons after pharmacologically relevant doses in vivo and reduces oxaliplatin nucleolar damage and neurotoxicity.

Abstract
A water soluble paclitaxel analogue, the 7-hemisuccinylpaclitaxel, was synthesised and its binding to human serum albumin (HSA) was characterised by difference circular dichroism and optical biosensor methodologies. The carboxylate group was introduced at paclitaxel C-7 position to improve the drug water solubility without significantly changing the biological activity. The paclitaxel analogue showed a relatively low affinity to HSA (3.5x10(4) M(-1)), while no significant interactions were evidenced with selective markers for the most characterised binding sites on the carrier, suggesting a non-selective binding to low affinity binding sites.

Abstract
Direct Raman imaging techniques are demonstrated to study the drug distribution in living cells. The advantage of Raman imaging is that no external markers are required, which simplifies the sample preparation and minimally disturbs the drug mechanism during imaging. The major challenge in Raman imaging is the weak Raman signal. In this study, we present a Raman image model to describe the degradation of Raman signals by imaging processes. Using this model, we demonstrate special-purpose image-processing algorithms to restore the Raman images. The processing techniques are then applied to visualize the anticancer agent paclitaxel in living MDA-435 breast cancer cells. Raman images were obtained from a cancer cell before, during, and after drug treatment. The paclitaxel distribution illustrated in these images is explained by means of the binding characteristics of the paclitaxel and its molecular target-the microtubules. This result demonstrates that direct Raman imaging is a promising tool to study the distribution of a drug in living cells.
