“…Modelling has shown that a variety of platins can be encapsulated inside the cavity of nanotubes, including cisplatin, nedaplatin, carboplatin and oxaliplatin (Mahdavifar & Moridzadeh 2014). Whilst either single or multi-walled carbon nanotubes can be used , the radius of the tubes does affect both the loading and release characteristics of the platins (Mejri et al 2015). A minimum radius of 4.8 Å is needed to accommodate cisplatin, with 5 Å the ideal radius (Hilder & Hill 2007).…”

The year 2015 marks the 50th anniversary since the discovery of the anticancer potential of cisplatin and it remains just as useful now as it did back then, especially for the treatment of some endocrine-related cancers like ovarian and testicular carcinomas. Since its discovery, five other platin drugs have received approval in various countries. While several new platin drugs are in preclinical development, in the last decade only two new platin drugs have entered clinical trials, LA-12 and dicycloplatin, reflecting a shift in research focus from new drug design to improved formulations of already approved platin drugs. These formulations include their encapsulation with macrocycles to slow and prevent their degradation by proteins and peptides; their attachment to nanoparticles to passively target solid tumours through the enhanced permeability and retention effect and their coordination to important nutrients, proteins, antibodies and aptamers for active tumour targeting. These formulation methods have all shown potential but none have yet yielded a new marketable medicine containing a platin drug. The reasons for this are problems of consistent drug loading, controlling the location and timing of drug release and the inherent toxicity of some of the drug delivery vehicles. In addition to drug delivery, functional genomics is now playing an increasing role in predicting patients' responses to platin chemotherapy and their likelihood of experiencing severe side effects.

“…It is clear that confinement energy and the product-CNT interactions 21 are the important factors to stabilize the products inside the CNT. Based on this, the relative importance of these interactions on the guest species within the CNT can be significantly affected by the change in morphology of each system studied; in principle, it could also lead to the changing of the activation barrier.…”

In this work, we focus our attention on chemical reactions confined within carbon nanotubes. As a result of the confinement within carbon nanotubes, novel physical and chemical properties are found for the confined materials. We consider the feasibility of proton transfer inside carbon nanotubes. To do that, we have chosen formamide as the simplest real model for exhibiting the tautomerization in DNA. We have used the quantitative structure–property relationship method, based on geometry optimization and quantum chemical structural descriptors, to illustrate the potential of using the confined space inside carbon nanotubes, which will provide comprehensive information about carbon nanotubes. All calculations have been carried out using density functional theory quantum calculations with the B3LYP functional. The geometries optimized by the Gaussian program were transferred to the computer software DRAGON to calculate pertinent descriptors that could be used in the quantitative structure–property relationship model.

The photophysical properties of a potential drug molecule rutaecarpine have been investigated in molecular as well as aggregated states. All systems have been characterized by various spectroscopic, microscopic and dynamic light scattering (DLS) techniques. The investigation has been carried out by keeping the fact in mind that hydrophobic organic molecules have a strong tendency to form aggregates in aqueous solution. A blue shift in the absorption spectrum of rutaecarpine has been observed for aggregates (compared to molecular solution) indicating the formation of H-type aggregates. The intermolecular interactions responsible for such aggregation have been further investigated through crystallographic and computational studies. It has been observed that π-π stacking interactions among the monomer units play an important role in the formation of H-type aggregates. Quantum mechanical calculations also substantiate the blue shift in the absorption that has been observed for aggregates. In the present case, enhanced emission for aggregates as compared to the molecular solution of rutaecarpine has also been observed. The observed enhanced emission upon aggregation is attributed to the decrease of the non-radiative rate constant (knr) upon aggregation. The effect of a surface active ionic liquid (SAIL), 1-dodecyl-3-methylimidazolium bromide ([C12mim]Br), on the aggregation of rutaecarpine has been investigated. Interestingly, in addition to the decrease in the particle size, a change in the morphology of the aggregates has also been observed with gradual addition of [C12mim]Br to the colloidal solution of rutaecarpine. The present study demonstrates that a SAIL can effectively be used as a medium for dissociation of colloidal aggregates and encapsulation of molecular species, which in turn would be helpful in influencing the drug activity.
