The spreading of resistance to antibiotics has fascinated researchers who have developed new antibiotics. However, it is predicted from history that new antimicrobials will have a short life. Thus, resistance to new drugs leads to a shortage of antimicrobials, as the discovery of new antimicrobial drugs is not enough to cope with the fast emergence of resistant strains. This requires new, potent antimicrobial compounds as an alternative to existing antibiotics. Phytochemicals with a low molecular weight could be an alternative source of antimicrobials. Natural molecules are a more promising...
