Natural antimicrobials are secondary metabolites that can be found in plants, animals, and microorganisms.Plants, especially herbs and spices, are been given more attention in natural antimicrobial research, however; this chapter focuses on the newly discoveries in fruits and vegetables. Microorganisms that are been used in food fermentation also produce different antimicrobial metabolites incl...

The efficiency of antibiotics in combating microbial infections was very promising shortly after their introduction. It was even thought that the microbial war was as good as over as was declared by the Surgeon General of the United States. However, resistance to these agents developed rapidly afterward and the problem of antibiotic resistance has remained a menace threatening the benefits of a...

This review covers the marine natural products literature for the year 2000 and is organized phylogenetically, with sections on marine microorganisms and phytoplankton, green algae, brown algae, red algae, sponges, coelenterates, bryozoans, molluscs, tunicates. echinoderms and miscellaneous marine organisms. There is an emphasis on new structures, stressing their biological activities, source o...

Plants and microbes contain a largely unexploited storehouse of phytotoxins that might be used directly or as structural indicators for new synthetic herbicides. Several factors have increased the interest of the herbicide industry in this source of natural products as herbicides. Natural compounds have made a large impact in the area of insecticides, whereas relatively minor successes have bee...

To prevent and treat diseases caused by the spread of microbes, humans have invented all sorts of effective antimicrobial substances. The most widely used antimicrobial substance is antibiotics. However, misuse of antibiotics can generate various negative effects, bacterial resistance, decreased immunity, and internal flora imbalance which can lead to endogenous infection. In addition, existing...

Rhizopodin (1, Scheme 1) is an architecturally unique polyketide macrolide that was originally isolated from the myxobacterium Myxococcus stipitatus by the groups of Hçfle and Reichenbach. It shows potent antifungal and antiproliferative cytotoxicity against a range of tumor cell lines with IC50 values in the low nanomolar range. [1] On a molecular level, 1 disrupts the cytoskeleton of actin by...
