A researcher from the University of Girona manages to isolate three natural products from the seabed to create new drugs

Girona (ACN)- Abdelatif el Marrouni, a researcher from the University of Girona (UdG), has managed to isolate three natural products from the the bottom of the sea around the world to create new drugs. In his thesis he explains the methods used for the first time to make these natural products of large structural ​​accessible to scientist from simple and commercially available compounds. The research responds to the need for new drugs to fight future infections or diseases such as cancer. The investigation is a cooperative effort between the Laboratoire de Chimie Organique de l’Ecole Superieur de Physique et Chimie Industrielles / Organic Chemistry Laboratory of the Superior School of Industrial Physics and Chemistry (ESPCI) of Paris.

Resistance to certain drugs and the emergence of new infections are a threat to human health. Given the difficulty in finding new tools to improve the immune system and taking nature as an inspiration, Marrouni started a research project focused on the seabed to find new therapeutic agents.

In this context, Marrouni has developed two projects which have in common the synthesis of new bioactive compounds. His thesis is called Synthesis of unusual alpha-amino acids and study of the effect of their incorporation into antimicrobial peptides. Total synthesis of bioactive marine natural products and analogues and has been led by Dr Montserrat Heras (UdG) and Dr Janine Cossy (ESPCI).

Among other advantages, the three natural products found on the bottom of the sea (Acremolide B, Bitungolide F and Lyngbouilloside), have considerable antitumor activity. Moreover, until now, the chemical structure of two of them has never been verified. Therefore, the researcher's thesis is the first that makes these large structural products accessible to scientist. As a result, it is now possible to work with three products from simple and commercially available compounds, which have interesting biological activities.

From Paris to Girona

The investigation arose from the collaboration between Professor Janine Cossy and Doctor Stellios Arseniyadis from the Organic Chemistry Laboratory of l’Ecole Superieur de Physique et Chimie Industrielles of Paris. The first project took place in France, but Marrouni developed the second part at the University of Girona, under the supervision of Doctor Montserrat Heras from the LIPPSO group (Chemical Department) and with the collaboration of the CIDSAV group of the Institute of Food Technology (INTEA).

The initial results of this second project identified products with promising biological profile, which will be used as a starting point for further study.
