Despite the rapid developments in nanotechnology and biomaterials, the efficient delivery of chemotherapeutic agents is still challenging. Prodrug-based nanoassemblies have many advantages as a potent platform for anticancer drug delivery, such as improved drug availability, high drug loading efficiency, resistance to recrystallization upon encapsulation, and spatially and temporally controllable drug release. In this review, we discuss prodrug-based nanocarriers for cancer therapy, including nanosystems based on polymer-drug conjugates, self-assembling small molecular weight prodrugs and prodrug-encapsulated nanoparticles (NPs). In addition, we discuss new trends in the field of prodrug-based nanoassemblies that enhance the delivery efficiency of anticancer drugs, with special emphasis on smart stimuli-triggered drug release, hybrid nanoassemblies, and combination drug therapy. © 2014 Elsevier B.V.

Water-assisted proton-catalyzed hydrolytic deamination of adenine to produce hypoxanthine has been studied using density functional theory method. Because adenine could be protonated at N1, N3, N7 and N10, four pathways initiated from the four different protonated adenines have been investigated. The first step of the four pathways is the nucleophilic attack of water with an assistant water to form a tetrahedral structure complex, and this is the rate-determining step. Including solvent effects decreased the relative energies of stationary points but have little effect on the structures. Pathway A is preferred due to the lowest energy barrier, and the relative free energy is 28.9 kcal/mol in vacuo. The outcomes show that adenine deamination under acidic condition is much easier to occur than under neutral condition due to lower energy barriers. The total atomic charge of C5 in the initial intermediate is correlated with the ease of deamination reaction. The more positive C5 atom is, the easier the deamination reaction is. © 2010 Springer-Verlag.
