Bioresponsive albumin-conjugated paclitaxel prodrugs for cancer therapy

The efficacy of traditional chemotherapy often suffers from rapid clearance and off-target toxicity. Drug delivery systems and controlled release are applied to improve the therapeutic efficiencies of smallmolecule drugs. In this work, two novel oxidative/reductive (Ox/Re) -sensitive and one non-sensitive Paclitaxel (PTX) prodrugs were synthesized with a maleimide group, which rapidly conjugates with albumin in vivo. Albumin serves as a good vehicle to deliver more prodrug to tumors due to the enhanced permeation and retention (EPR) effect. PTX was then released from the prodrugs in glutathione(GSH)/ reactive oxygen species(ROS)-rich tumor microenvironments. This bioresponsive prodrug strategy demonstrates potent chemotherapeutic efficiency in vivo and may be utilized in clinical cancer therapy.

New AB-monomers containing either furyl and maleimide groups or hydroxy and acid groups were prepared by the reaction of 4-maleimidobenzoic acid chloride or 4-maleimidophenylisocyanate with 2-furfuryl alcohol or the Diels-Alder reaction of 4-maleimidobenzoic acid with 2-furfuryl alcohol, respectively. The structures of the monomers were confirmed by IR, 1H-NMR and elemental analysis. By Diels-Alder polymerization reaction or polycondensation reaction new poly(esther-imide) or poly(urethane-imide)s were prepared. Thermal curing behavior of monomers was investigated by DSC analysis. All polymers were characterized by elemental analysis, IR spectral studies and thermogravimetry.

Highly beta-regioselective Friedel-Crafts aminoalkylation of pyrroles with cyclic perfluoroalkylated imines

A Friedel-Crafts-type alkylation reaction was studied between various pyrroles and alpha-polyfluoroalkylated cyclic imines that were activated by Lewis acids. The reaction proceeded under mild conditions and provided a high yielding synthesis of alpha-CF3-substituted pyrrolidines and piperidines as well as seven-membered analogues that contained a pyrrole ring. The unpredictably high beta-selectivity for the aminoalkylation of both 1H-pyrrole and N-substituted pyrrole was observed as a result of a thermodynamically-controlled electrophilic substitution reaction. The computational data are in full agreement with the experimental results, which confirmed the observed regioselectivity as a result of the lower energy of the beta-substituted pyrroles that contain alpha-trifluoromethyl-substituted pyrrolidine, piperidine, and azepane rings. Trifluoromethyl-substituted cyclic imines were activated by various Lewis acids and underwent a reaction with pyrrole derivatives. An unpredictable beta-selectivity was observed. The regioselectivity of the aminoalkylation was explained by computation data, which also confirmed the isomerization of the alpha isomer into the beta isomer. Copyright

The bisphosphine ligand 1c is highly efficient and selective for the asymmetric hydroformylation (AHF) of dihydrofuran and pyrrolines. The AHF of 2,3-dihydrofuran yielded the 2-carbaldehyde in up to 93% ee. The remarkable highest regioselectivity of 2,5-dihydrofuran was obtained to date up to 499 beta-isomer/alpha-isomer with ligand 1c.

New functional handle for use as a self-reporting contrast and delivery agent in nanomedicine

The synthesis and photophysical characterization of a chromophore-bridged block copolymer system is presented. This system is based on a dithiomaleimide (DTM) functional group as a highly emissive functionality which can readily be incorporated into polymeric scaffolds. A key advantage of this new reporter group is its versatile chemistry, ease of further functionalization, and notably small size, which allows for ready incorporation without affecting or disrupting the self-assembly process critical to the formation of core-shell polymeric contrast and drug delivery agents. We demonstrate the potential of this functionality with a diblock system which has been shown to be appropriate for micellization and, when in the micellar state, does not self-quench. The block copolymer is shown to be significantly more emissive than the lone dye, with a concentration-independent emission and anisotropy profile from 1.5 mM to 0.15 muM. An emission lifetime and anisotropy decay comparison of the block copolymer to its micelle displays that time-domain fluorescence lifetime imaging (FLIM) is able to rapidly resolve differences in the supramolecular state of this block-dye-block polymer system. Furthermore, the ability to resolve these differences in the supramolecular state means that the DTM micelles are capable of self-reporting when disassembly occurs, simply by monitoring with FLIM. We demonstrate the great potential for in vitro applications that this system provides by using FLIM to observe micelle disassembly in different vascular components of rat hippocampal tissue. In total this system represents a new class of in-chain emitter which is appropriate for application in quantitative imaging and the tracking of particle degradation/disassembly events in biological environments.
