Rifampicin Antagonizes the Effect of Chloroquine on Chloroquine

... Chloroquine (CQ) has been one of the most successful and widely prescribed drugs for malaria due to its efficacy and safety. It is believed that CQ interferes with the heme polymerisation process of plasmodia, which converts heme into non-toxic hemozoin in the food vacuole by forming toxic heme-CQ c ...

Potential antimicrobial agents for the treatment of multidrug-resistant tuberculosis

... Multidrug-resistant (MDR) tuberculosis (TB) is defined as an infectious disease caused by Mycobacterium tuberculosis that is resistant to at least the two most powerful drugs currently known: isoniazid and rifampicin [1–4]. Treatment of MDR-TB is complex, using toxic drugs that must be administered ...

Discovery and development of cephalosporins



Cephalosporins are a broad class of bactericidal antibiotics that include the β-lactam ring and share a structural similarity and mechanism of action with other β-lactam antibiotics (e.g. penicillins, carbapenems and monobactams). The cephalosporins (and other β-lactams) have the ability to kill bacteria by inhibiting essential steps in the bacterial cell wall synthesis which in the end results in osmotic lysis and death of the bacterial cell. Cephalosporins are widely used antibiotics because of their clinical efficiency and desirable safety profile.The cephalosporins are diverse in their antibacterial spectrum, water solubility, acid tolerability, oral bioavailability, biological half-life and other properties. Therefore the cephalosporins can be further classified into generations depending on antibacterial activity, time of invention and structural basis.
