Background and objectives: Astragalus is one of the most abundant genera of flowering plants in Iran. There are a few reports on phytochemical investigation of this valuable genus. Saponins, flavonoids and polysaccharides have been reported as the most important metabolites in Astragalus species. In the present research, we aimed to identify the foremost const...

Background: The microbial genome sequences provide solid in silico framework for interpretation their drug-like chemical scaffolds biosynthetic potential. The Pseudomonas fluorescens species is metabolically versatile and producing therapeutically important natural products.Objectives: The main objective of the present study was to mine the publically available data of P. fluorescens stra...

 Over recent years, nosocomial infections, and the morbidity and mortality associated with pathogenic bacteria have dramatically increased due to antibiotic resistance and imposed significant burdens on the global health system. Critical shortage of effective therapeutics against multidrug-resistant bacteria highlights the need for development of novel antibiotics. Actinobacteria are well-known...

Sponges are the most primitive and simplest multicellular animals. These organisms don’t have any mechanical defense system, so their early appearance in evolution has given them a lot of time for the development of advanced secondary metabolites as chemical defense system. Sponges have the potential to provide drugs from chemical components against diseases, such as antibacterial. Antimicrobia...

This review described the physiological and biochemical effects of various secondary metabolites from Meliaceae against major Lepidopteran insect pest including, Noctuidae and Pyralidae. The biochemical effect of major Meliaceae secondary metabolites were discussed more in this review. Several enzymes based on food materials have critical roles in nutritional indices (food utilization) of the i...
