Resumen:
Un grupo de investigación español de microbiología ha patentado una nueva cepa bacteriana de Streptomyces carnosus capaz de producir por fermentación compuestos citotóxicos de la familia de loboforinas de forma eficiente. Esta cepa produce una nueva loboforina con actividad citotóxica contra diferentes líneas celulares tumorales y actividad antibacteriana contra bacterias patógenas. El grupo de investigación busca compañías en los sectores de microbiología y farmacia con el fin de desarrollar sus aplicaciones bajo acuerdos de licencia.

Details

Tittle:
Novel antibiotic and antitumor agent produced by the deep sea actinobacterium Streptomyces carnosus.
Summary:
A Spanish research group in microbiology has patented a novel bacterial strain of Streptomyces carnosus, able to efficiently produce by fermentation cytotoxic compounds of the family of lobophorins. Specifically, this strain is producing a new lobophorin, having cytotoxic activity against different tumour cell lines and antibacterial activity against pathogenic bacteria. Companies in microbiology and pharmacy are sought to develop applications of the described invention under license agreements.
Description:
Marine environments are emerging as a source of new natural products of pharmacological importance and coral reefs have revealed as a medium that should be investigated to discover structurally unique natural products with biomedical relevance. Due to the increasing need for new antitumor agents with improved activity, fewer undesirable side effects and greater selectivity compared to the current drugs in use in the fight against cancer and to the increasing emergence of current antibiotic-resistant pathogenic bacteria, it is necessary the development of new antitumor agents with improved pharmacological properties and of new antibiotics with potential biomedical treatment or prevention of infectious diseases caused by pathogenic bacteria. It is also necessary to have simple, short and economical methods for obtaining such compounds with antitumor and / or antibacterial activity.

Researchers from a Spanish university working in microbiology provide a novel bacterial strain of Streptomyces carnosus that has been isolated from its natural environment, which is able to efficiently produce by fermentation cytotoxic compounds of the family of lobophorins. Specifically, this strain is producing a new lobophorin, which has cytotoxic activity against different tumour cell lines.

The present invention thus relates to a bacterial strain of Streptomyces carnosus, to a supernatant or extract of a culture of such bacterial strain, to the use of the bacterial strain for the production of certain lobophorin, to a process for obtaining said lobophorin, to a pharmaceutical or cosmetic composition, to the manufacture of a medicament for the treatment of cancer and for the treatment and / or prevention of bacterial infections or for removal and / or prevention and / or inhibition of bacterial biofilm formation, preferably on inert surfaces, i.e. ex vivo.

The researchers would like to reach license agreements with companies operating in the clinical microbiology and pharmacy fields with the aim to develop applications of the described technology.
Advantages and Innovations:
The present invention represents a solution to the need for new antitumor compounds with biomedical potential in the treatment or prevention of infectious diseases caused by Gram positive pathogenic bacteria. It also represents a solution to the need for simple, short and economic procedures for obtaining said compounds with antitumor and antibacterial activity as the method of the invention allows to produce such compound by fermentation with an actinobacteria, rather than by chemical synthesis, which is a more complex, lengthy and costly process. In this regard, in biotechnological processes involving obtaining structurally complex natural products, such in the case of lobophorins, the production by fermentation using the producing microorganism is the preferred method because it is simpler, shorter and cheaper than the organic synthesis procedure.
