Vicente Martí Centelles current research interests focuses on supramolecular systems based on molecular cages for advancing the field of cancer therapy. The project will develop molecular cages with tailored properties for biological applications. The project SupraLib is funded by the Proyectos de I+D+i 2020 Angencia estatal de investigación y Ministerio de Ciencia e Innovacion (MICIU/AEI/10.13039/501100011033, project PID2020-113256RA-I00).

In this research line, we aim to develop molecular cage systems to encapsulate drugs for cancer therapy. To achieve this ambitious goal we focus on the cage design, starting from the geometry of the building blocks to achieve the desired cage geometry.

Researchers from the Universitat Politècnica de València and the University of Oxford have designed software that facilitates the design of molecular cages for drug encapsulation

By improving the design of the cages, the software makes the encapsulation and subsequent release of drugs in the body more efficient

• 

The work was on the cover of the Journal of Chemical Information and Modeling last July A team from the Institute of Molecular Recognition and Technological Development (IDM) of the Universitat Politècnica de València (UPV) and the University of Oxford has developed new software that, among many other applications, facilitates the design of molecular cages for drug encapsulation.

Called CageCavityCalc -C3- this software specifically allows the automated calculation and visualization of the cavity size of molecular cages used in biological applications and which are used, for example, for the administration of anticancer drugs. The work was featured on the cover of the Journal of Chemical Information and Modeling last July. "The CageCavityCalc software uses a novel algorithm that allows the calculation of the cavity size of molecular cages and properties such as hydrophobicity and electrostatic potential, which provides key information to optimize the design of the molecular cage that houses the drugs, for their subsequent release into the body in the most efficient way possible," explains Vicente Martí Centelles.

Molecular cages are also used in other applications such as sensors and molecular recognition, catalysis, etc. The fundamental key to their optimal functioning lies in their internal cavity, so that they are capable of encapsulating guest molecules and modulating their properties. "However, today, the design of cages with specific properties is a challenge and the development of software that helps predict the properties is essential. And our work responds to this challenge," highlights Vicente Martí Centelles.

According to the IDM researcher, to date the calculation of molecular properties and cavities requires the use of "command line"-based software and parameter adjustments by the user. Meanwhile, CageCavityCalc has a graphical interface that allows non-specialists to use this tool without needing to have computer programming knowledge. In addition, the cavity calculation is completely automated, which avoids the need to make parameter adjustments to perform the calculation. "The main advantage of the CageCavityCalc software is its efficiency and ease of use, in addition to being free and open source. It speeds up cavity calculations, thus facilitating the development of new functional molecular cages, with the appropriate properties for their different applications. In short, it greatly simplifies the design of these cages, while optimizing their operation," concludes Vicente Martí Centelles.

Molecular cages to improve the effectiveness and reduce the toxicity of anticancer drugs

• 

• 

A team from the Universitat Politècnica de València (UPV), CIBER-BBN and the University of Edinburgh has just published a strategy based on the use of molecular systems for the encapsulation and release of drugs with possible applications in future cancer therapies. In their study, they encapsulated an anticancer drug in a molecular cage that responds to changes in pH and verified its effectiveness against cancer cells. Their results have been published in the journal Chemical Science, which has also selected the project for one of its inside covers.

Molecular cages are structures that completely envelop the host molecules, in this case encapsulating a drug and leaving it in an inactive state for its subsequent release - recovering its activity.

The study, which has been developed as part of Giovanni Montà's doctoral thesis project, has allowed the start of the line of research into molecular cages for biological applications.

"In our research, evaluated in vitro tests on cells, we have carried out a comparative analysis between two analogous cages: a metal-organic cage and another organic cage. This is a unique study, of great relevance to be able to advance which type of cage is better for biological applications and, in this specific case, to fight against these cancer cells," explains Giovani Montà

For future developments of anti-cancer drug release systems In their study, the IDM-UPV and CIBER-BBN team, in collaboration with Paul Lusby of the University of Edinburgh, has verified that the organic molecular cage has better properties than the metal-organic cage, and allows better administration of the drug due to its lack of toxicity.

Vicente Martí, researcher at the IDM-UPV and CIBER-BBN, explains that the organic cage stands out for its high cellular compatibility, since it does not show any cellular toxicity even at high doses, unlike the metal-organic cages, in which toxicity was observed.

"In addition, the organic box delivers the anticancer drug doxorubicin effectively to the cells, preserving the cytotoxic activity of this anticancer drug," says David Bastante, a predoctoral researcher at the IDM-UPV.

In this way, according to Alba García, a CIBER-BBN researcher, this study establishes the basis for future developments of drug release systems based on molecular boxes, applied to the treatment of pathologies such as cancer.

Following the good results of the system developed in its laboratories, the IDM, CIBER-BBN team continues to work on improving its properties. "Our goal is to obtain a system that allows us to advance in biological applications, and to be able to carry out in vivo tests," concludes Ramón Martínez-Máñez, director of the IDM Institute at the UPV and also a CIBER-BBN researcher.

Pint of Science

• 

Vicente recently gave a talk at Pint of Science in Valencia 2024, where he discussed topics in chemistry, specifically focusing on nanomaterials and molecular cages. Pint of Science is a global science festival that connects researchers with the public in local bars and cafes.

During his presentation, Vicente explained the potential of nanomaterials, which are small structures with applications in fields like medicine and energy production. He also covered molecular cages, chemical structures that can trap and release molecules, with uses in drug delivery among other fields.

The talk provided an opportunity for the public to learn about these topics in an informal setting. Vicente communicated these concepts, making them accessible among the audience. The event highlighted the importance of science communication, showing how scientific ideas can be shared in an engaging way.
