Happy Day of Chemistry! The role of Chemistry in a sustainable research in health

Today, November 15 is a day of celebration for us, the Day of the Chemistry in Spain!

Chemistry is the science that studies matter, how it is composed, its properties and how its structures are transformed and, as matter is everything, including living beings and ourselves, we can say that chemistry is omnipresent and transversal in all areas surrounding us. Chemistry is everywhere, we ourselves are chemistry and our health and our life is chemistry.

Everything around us is chemistry in the environment, foods, what we use and what we touch every day. Our own body is a sophisticated complex factory with an infinite number of chemical processes taking place on a perfect and synchronized manner”- points Pilar Marco, Scientific Director of NANBIOSIS U2 Custom Antibody Service (CAbS) from CIBER-BBN at IQAC-CSIC.

The crucial role of chemistry in everyday life is also evidence in the development of current technology and the economy. According the VCI Prognos Study, the Global growth forecast for Industrial Sectors, places the chemical industry in the fist position. As far as national picture, the INE Statistics on R+D Activities 2020 -last publish report-, chemical and pharmaceutical industry employs the 22,2 % of research staff recruited and the investment and expenditure on the chemical and pharmaceutical industry represents the 23,6% R+D and Innovation -above the motor vehicles industry.

Thanks to chemical and pharmaceutical research,

medicines, vaccines and health products have made great strides in fighting diseases and improving quality of life. Thanks to chemical and pharmaceutical medicine research, in few years, it will be possible, for example, to count on smart implants delivering personalised drugs only where cancer or infections are detected or biosensors circulating in our body to find diseases only one week after infection.

At the Institute of Advanced Chemistry of Catalonia, four NANBIOSIS units of CIBER-BBN use chemistry to deliver new therapeutic and diagnostic approaches that improve the quality of life of the society.

One of the research lines of the Nb4D group-U2 CabS at IQAC-CSIC (led by Pilar Marco and Nuria Pascual) focuses on the chemical signals that bacteria emit to communicate with each other and thus develop virulence mechanisms. Their knowledge will allow the development of new therapeutic and diagnostic strategies to mitigate the serious problem of antimicrobial resistance.

NANBIOSIS U3 Synthesis of Peptides UnitMS4N group, led by Miriam Royo, explores the use of diverse types of chemical multivalent platforms (oligomers, dendrimers, polymers, micelles and lipid nanovesicles) for the development of drug delivery systems for cancer treatment, protein delivery systems for the treatment of lysosomal diseases and macromolecular compounds that have intrinsically therapeutic properties with application to central nervous system diseases.

Chemistry plays an essential role in helping society achieve Sustainable Development Goals (SDGs)

In 2015 the United Nations created a universal call to action to end poverty, protect the planet, and ensure that all people enjoy peace and prosperity by 2030. This framework, comprising 17 aspirational goals known as the Sustainable Development Goals (SDGs)

Chemistry is key to achieve the SDG 3: Good Health & Well-Being with the development of new technologies that will provide a deeper understaunding of human health, making posible better, cheeper and faster medical diagnosis and treatmens.

In this sense, Carlos Rodriguez Abreu, Scientific Director of NANBIOSIS Unit for the characterization of nanostructured liquids (U12) explains: “The goals of sustainable development are producing a shift towards surfactants not based on petroleum derivatives, but derived from other raw materials that are more biocompatible and that allow a circular economy that is less aggressive with the environment. Quality control is necessary with regard to the properties of the products that contain surfactants, such as the droplet size in emulsions, the particle size in suspensions, their colloidal stability over time, among others. Additionally, products must be precisely formulated to optimize the use of raw materials and obtain the desired properties. In this context, the NANBIOSIS U12, acredited with ISO 9001:2015 by AENOR, offers a wide range of advanced analysis techniques for the determination of different colloidal properties such as droplet size and particle size, colloidal stability, viscosity, surface tension, pore size distribution, and determination of phase behavior and structure for the tailor-made formulation of surfactant and colloid systems for pharmaceutical and biomedical applications.

The Nucleic Acid Chemistry group at IQAC-CSIC – NANBIOSIS U29 Oligonucleotide Synthesis Platform (OSP) is developing new compounds based in DNA and RNA to detect and treat diseases participating in several projects with several research and industrial partners such as La Marato de TV3 (Covid), Oligofastx, Caminan2, Osteoatx. These new drugs use the natural mechanisms for gene regulation to treat undruggable diseases such Muscular dystrophy and others. Importantly special attention is made to design novel synthetic protocols to produce less organic waste what contributes to the sustainable development. 

We wish to all the family of chemistry professionals new projects and inspiration to achive humans Good Health & Well-Being and keep the world moving!

And Happy Chemistry Day, too, for all the chemistry enthusiasts!

This forum brought toguether researchers from the most eminent national research centers in nanomedicine, that during the two days meeting presented their works and findings and discussed the impact of nanomedicine in the fields of drug delivery, diagnosis and therapy.

The workshop was open by the Director of IQAC-CSIC,  Jesús Joglar, the  Scientific Coordinator of Nanomed Conection, Fernando Herranz, and the Scientific Director of CIBER-BBN, Ramón Martínez Máñez.

18 research groups gave their talks distributed in four sessions:

  • Nanobiotechnological solutions for diagnosis and therapy
  • Drug delivery nanosystems
  • Applications for oncology 
  • Nanomedicine & other frontier applications

The presentations aroused great interest and futher debate among the attendees present in the auditorium (around 50) and the on line participants (The event was also broadcast online previous registration with more than 125 registrations received).

The videos of the presentations will be soon available in the NANBIOSIS youtube channel.

Here we highlight the eight talks by researchers from NANBIOSIS units:

The first session of Nanobiotechnological solutions for diagnosis and therapy,  started  with the talk by Montserrat Rodríguez from Nb4D group NANBIOSIS U2 CAbS, from CIBER-BBN and IQAC-CSIC, entitled “Targeting aromatic amino acid metabolism for the early diagnosis of neurological diseases”, presenting their results on in vitro samples, on thermal power characterization experiments to study the thermal efficiency of non-sinusoidal stimulation and on efficiency characterization experiments in cell cultures with cancer cell liness.

Also in this session chaired by Miriam Royo, Scientific Coordinator of NANBIOSIS U3 Synthesis of Peptides Unit of  CIBER-BBN and IQAC-CSIC,  took place an interesting and passionate talk by Ramón Eritja, Scientific Director of NANBIOSIS U29 Oligonucleotide Synthesis Platform (OSP)

In the last years, interest in therapeutic applications of oligonucleotides has increased enormously, especially after the development of messenger RNA vaccines in response to the COVID-19 pandemic. In this way, metabolic diseases such as dyslipidemia and hereditary diseases such as Duchenne muscular dystrophy have been successfully addressed. The NANBIOSIS  Oligonucleotide Synthesis Platform (OSP) focuses on the design, synthesis and characterization of modified oligonucleotides, in order to enhance the therapeutic properties of the oligonucleotides and to improve the control of gene expression. Ramon Eritja presented their most recent results in the development of new conjugates with antiproliferative activity and in the design of DNA probes for the detection of viral genomes.

 

In the session of “Nanomedicine and other frontiers applications”, chaired by María del Puerto Morales Herrero (ICMM-CSIC), Elena Martínez Fraiz,  from the Nanobioengineering group of CIBER-BBN and IBEC running NANBIOSIS Unit 7 of Nanotechnology, presented  a nanostructured surface able to produce multivalent effects of surface-bound ephrinB1 ligands on the dynamics of oligomerization of EphB2 receptors  whic can benefit applications such as the design of new bioactive materials and drug-delivery systems.

The session of Drug delivery nanosystems, chaired by Ramón Martínez Máñez, began with the talk by Vanessa Díaz Riascos, presesnting the in vivo efficacy, biodistribution and toxicity testing of nanomedicines at NANBIOSIS U20 FVPR, of CIBER-BBN and VHIR, explaining how their texting expertise and their in vivo and ex vivo fluorescence imaging techniques facilitate a rapid and efficient preclinical development of candidates, reducing considerably the time and costs of conventional developments.


Santiago Grijalvo Torrijo, from NANBIOSIS U12 Nanostructured liquid characterization unit expoke about Nano-emulsion-derived polymeric carriers for biomedical applications also discussing the impact of the protein corona on colloidal stability, antioxidant activities, cytotoxicity and cellular uptake of drug-loaded nanoparticles.

Antoni Llopis Lorente, (NANBIOSIS U26 NMR: Biomedical Applications II), expoke about Gated silica nanoparticles for controlled release. Chemical communication, based on the exchange of molecules as messengers, allows different entities to share information, cooperate and orchestrate collective behaviors. Communication using chemical messengers (such as neurotransmitters, hormones and pheromones) is the main way of communication across the natural world; yet engineering chemical communication between micro/nanosystems is a key emergent topic in micro/nanotechnology, biomimicry and related areas. Santiago explainined recent progress by their group in the development of engineered particles for chemical communication and nanomedicine applications.

And closing the session, Mariana Köber (Nanomol Group –NANBIOSIS U6 of Biomaterial Processing and Nanostructuring Unit  from CIBER-BBN and ICMAB-CSIC) gave a talk on Quatsomes as versatile nanovesicles for biomedical applications.

In the session of Applications for Oncology, Pilar Martín Duque from NFP group – NANBIOSIS U9 Synthesis of Nanoparticles Unit of CIBER-BBN and INMA-CSIC, gave a very interesting talk explained their approach and recent progress on the search of trojan horses for an improved theragnosis of cancer.

Here we want to thank the Institute of Advanced Chemistry of Catalonia (IQAC-CSIC) for hosting this event and for the help in its preparation and development.

New results evidence new biomarkers for early diagnosis of P. aeruginosa infections

Pseudomonas aeruginosa is a common multidrug-resistant pathogen that causes acute and chronic infections. However, P. aeruginosa, as many other bacterial species, has developed resistance to antibiotics being difficult to treat. For this reason diagnostic methods allowing detection at early  stages of the infection are required  and, therefore, efficient biomarkers of infection are very helpful. These fast diagnosis will help on the subsequent therapeutic treatment.

The Nb4D group of CIBER-BBN and IQAC-CSIC (led by M.-Pilar Marco) has recently conducted a research to develop a highly sensitive, specific and reliable immunochemical assay to detect pyocyanin (PYO), one of the most important virulence factors of Pseudomonas aeruginosa.

The assay uses a high-affinity monoclonal antibody produced by the unit 2 of the ICTS NANBIOSIS Custom Antibody Service (CAbS) (Dr. Núria Pascual).

The microplate-based ELISA developed is able to achieve a limit of detection (LoD) of 0.07 nM, which is much lower than the concentrations reported to be found in clinical samples (130 µM in sputa and 2.8 µM in ear secretions). The ELISA has allowed the investigation of the release kinetics of PYO and 1-OHphz (the main metabolite of PYO) of clinical isolates from P. aeruginosa-infected patients. Significant differences have been found between clinical isolates obtained from patients suffering an acute or a chronic infection (~6,000 nM vs. ~8 nM of PYO content, respectively).

The results found point to a real potential of PYO as a biomarker of P. aeruginosa infection and the possibility to use such virulence factor also as a biomarker for patient stratification and for an effective management of these kinds of infections.

The Roundtable discussed the applications of nanomedicine in the Medicine of the Future and in Personalized Precision Medicine, as well as the challenges facing nanomedicine.

The Observatory of Trends in the Medicine of the Future, promoted by the Roche Institute Foundation, aims to generate and disseminate knowledge in areas of incipient knowledge related to Personalized Precision Medicine and that are part of the Medicine of the Future.

In this context, the fundation Instituto Roche has recently published a report on nanomedicine coordinated by Ramón Martínez in which José Becerra, María Pilar Marco and María Jesús Vicent have participated as experts.

Currently, nanoparticles or nanostructures are being applied for the controlled release of drugs in cancer and other pathologies and nanodevices for the diagnosis of diseases or the development of nanomaterials for applications in regenerative medicine. In the coming years, and with the translation into clinical practice of more and more developments based on these technologies, nanomedicine will contribute to the medicine of the future approaching the diagnosis and treatment of diseases earlier, more efficiently and in a more efficient and personalized way.

‘Point-of-care or PoC’ devices are able to directly detect the genetic material of the virus in just 30 minutes

Twenty five Spanish researchers linked to the Higher Center for Scientific Research, CSIC, who are working more directly on the project ‘Point-of-care tests for the rapid detection of SARS-CoV-2’ – Studies for the development of technologies effective diagnosis and early detection of SARS-CoV-2- have met since last Wednesday and until this Friday at the Benasque Science Center ‘Pedro Pascual’ to analyze the state or of the different programs and lines of research on the covid-19.

After months of intense work, among the most outstanding achievements in relation to the detection of the genetic material of the virus, is the development of a series of technologies that allow this detection without the need for PCR. Researchers have managed, by designing specific probes, to directly detect the genetic material of the virus in just 30 minutes.

Dra. Pilar Marco, researchar of CSIC and Scientific Director of Nanbiosis U2 Custom Antibody Service (CAbS) – explains that “the PCR technique, which it is very sensitive and very precise, has a disadvantage in terms of time because it requires an amplification stage of this genetic material that makes the process long, this is going to revolutionize the diagnosis, not only for Covid-19, but also of other infectious diseases”.

Researcher of three units of NANBIOSIS, attended the meeting and some of them gave talks:

  • Nuria Pascual, Scientific Coordinator of NANBIOSIS U2 CAbS espoke about Antibodies production
  • Also from NANBIOSIS Unit 2, J. Pablo Salvador espoke about Immunochemical tests and .
  • Serological test of peptide epitopes were explained by Julian Guercetti.
  • Anna Avigñó, Scientific Coordinator of NANBIOSIS U29, espoke about Design of oligonucleotides for a new method in Covid-19 detection without PCR.
  • And Macarena Duran, representing MS4N group and the Peptide synthesis unit of NANBIOSIS (U3) explained the synthesis of potential SARS-COV2 epitopes that have been applied for hybridome selection for mAb and to generate epitope microarrays to analyze serological samples.

The meeting has served to share the most relevant results that have been obtained in the context of the project, as well as discussion of new strategies to address problems that have arisen throughout the project and in turn, discuss future objectives.
