Natural products as potential biopesticides

Controlling pests is a major concern in agriculture and it is still strongly dependent on the use of synthetic herbicides, which determined, in the last fifty years, the accumulation of the toxins in the ecosystem and the rapidly evolving resistance. The natural substances produced by plants and microorganisms (essentially fungi and bacteria) can be an important part of future crop protection research. Natural products have had a substantial impact on pest control by providing molecules that are effective as pest control agents and identifying novel mode of actions and serving as inspiration/models for synthetic pesticides. Our research activity is focused on the extraction, purification and chemical characterization of bioactive compounds produced by plants and microorganisms using chromatographic and spectroscopic methods. The overall aim is the selection of bioactive natural products for development of new eco-friendly biopesticides (bioherbicides, insecticides, fungicides and bactericides).  The application of pesticides needs a suitable formulation that increase their efficacy by in filed application this could be realized by including the bioactive natural metabolite in biofilm to obtain sprayable emulsion and sheeting to apply on the soil.

FORMULATION OF NATURAL PRODUCTS OF NATURAL PRODUCTS IN BIOFILM FOR APPLICATION IN AGRIFOOD 

Moulds may represent a risk for health since they can cause allergic reactions and respiratory

problems and in the case of mycotoxigenic fungi, they are capable of causing mycotoxicosis in animal and humans. Fungal contamination represents one of the main concerns for food preservation as food surface, including bread, fruit, vegetables and dairy products are easily spoiled by moulds. Big problem for the production and health of fish production in aquaculture were also to fight the pathogenic bacteria and the wide production of algae. These problems could be overcome producing the so-called intelligent packaging including antifungal natural compound in suitable biofilm of produced film incorporating natural bactericides and algaecide to apply on the tank wall.

NATURAL PRODUCTS WITH POTENTIAL APPLICATION IN MEDICINE 

Natural products from microorganisms and plants play a leading role in drug discovery resulting in a large number of clinically useful agents. Many of these natural products have displayed notable in vitro growth inhibitory properties in human cancer cell lines and select compounds have been demonstrated to provide therapeutic benefits in mouse models of human cancer. Many of these compounds are expected to enter human clinical trials in the near future. Our research activity is focused on the isolation and chemical characterization of bioactive compounds produced by microorganisms and plants to find bioactive natural substances with new modes of action for development of new anticancer agents. Natural products could also represent an efficient solution in discovering and developing new drugs to overcome antimicrobial resistance and treat biofilm-related infections.
