DrugBank Description: | Benzylpenicillin (Penicillin G) is narrow spectrum antibiotic used to treat infections caused by susceptible bacteria. It is a natural penicillin antibiotic that is administered intravenously or intramuscularly due to poor oral absorption. Penicillin G may also be used in some cases as prophylaxis against susceptible organisms. Natural penicillins are considered the drugs of choice for several infections caused by susceptible gram positive aerobic organisms, such as *Streptococcus pneumoniae*, groups A, B, C and G streptococci, nonenterococcal group D streptococci, viridans group streptococci, and non-penicillinase producing staphylococcus. Aminoglycosides may be added for synergy against group B streptococcus (*S. agalactiae*), *S. viridans*, and *Enterococcus faecalis*. The natural penicillins may also be used as first or second line agents against susceptible gram positive aerobic bacilli such as *Bacillus anthracis*, *Corynebacterium diphtheriae*, and *Erysipelothrix rhusiopathiae*. Natural penicillins have limited activity against gram negative organisms; however, they may be used in some cases to treat infections caused by *Neisseria meningitidis* and *Pasteurella*. They are not generally used to treat anaerobic infections. Resistance patterns, susceptibility and treatment guidelines vary across regions. |
CAS Number: | 61-33-6 |
Molecular Weight: | 334.39 |
DrugBank Indication: | For use in the treatment of severe infections caused by penicillin G-susceptible microorganisms when rapid and high penicillin levels are required such as in the treatment of septicemia, meningitis, pericarditis, endocarditis and severe pneumonia. |
DrugBank Pharmacology: | Penicillin G is a penicillin beta-lactam antibiotic used in the treatment of bacterial infections caused by susceptible, usually gram-positive, organisms. The name "penicillin" can either refer to several variants of penicillin available, or to the group of antibiotics derived from the penicillins. Penicillin G has <i>in vitro</i> activity against gram-positive and gram-negative aerobic and anaerobic bacteria. The bactericidal activity of penicillin G results from the inhibition of cell wall synthesis and is mediated through penicillin G binding to penicillin binding proteins (PBPs). Penicillin G is stable against hydrolysis by a variety of beta-lactamases, including penicillinases, and cephalosporinases and extended spectrum beta-lactamases. |
DrugBank MoA: | By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, penicillin G inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that penicillin G interferes with an autolysin inhibitor. |
Targets: | Penicillin-binding protein 3 inhibitor; Solute carrier family 22 member 8 substrate&inhibitor; Solute carrier family 15 member 1 substrate&inhibitor; Solute carrier family 15 member 2 inhibitor |

I01 | 552 | Pneumonia | A lung disease that involves lung parenchyma or alveolar inflammation and abnormal alveolar filling with fluid (consolidation and exudation). It results from a variety of causes including infection with bacteria, viruses, fungi or parasites, and chemical or physical injury to the lungs. It is accompanied by fever, chills, cough, and difficulty in breathing. http://en.wikipedia.org/wiki/Pneumonia | disease of anatomical entity/respiratory system disease/ lower respiratory tract disease/lung disease | Details |
