Bacterial resistance to therapeutic drugs is a global problem making many of the bacterial infectious dangerous epidemics. Hence search is on for newer and more effective antibiotics. The problem of new antibiotics is often they are toxic to humans because of their complex nature more over bacteria are known to develop resistance to all these drugs quickly. Currently six molecular targets are used in antibacterial therapy. Potentially bacteria are expected to have over 2000 targets for antibacterial therapy. Hence new antibiotics are directed towards any of these newer targets.
