Currently, most commonly used antibiotics work by attacking the cell walls of bacteria or preventing the production of growth proteins. However, over time bacteria evolve and develop resistance. This growing trend has scientists worried, with experts warning that the lack of antibiotics effective agains...
In this Review, we discuss the multilayered effects of drug-target interactions, including the essential cellular processes that are inhibited by bactericidal antibiotics and the associated cellular response mechanisms that contribute to killing. We also discuss new insights into these mechanisms that ...
What happens if antibiotics don't work for bacterial infections? When bacteria become resistant,the original antibiotic can no longer kill them. These germs can grow and spread. They can cause infections that are hard to treat. Sometimes they can even spread the resistance to other bacteria that...

Many antibiotics, including penicillin, work by attacking the cell wall of bacteria. Specifically, the drugs prevent the bacteria from synthesizing a molecule in the cell wall called peptidoglycan, which provides the wall with the strength it needs to survive in the human body. But there are mu...
Physical insights into permeation of and resistance to antibiotics in bacteria. Bacteria can resist antibiotics simply by hindering physical access to the interior, where in general antibiotic targets are located. Gram-negative bacteri... M Ceccarelli,P Ruggerone - 《Current Drug Targets》 被引量:...
Penicillins, an example of narrow-spectrum antibiotics, work by destroying the structure of a cell wall, the layer that holds the whole cell together; glycopeptide antibiotics also go to work on the structure of a cell wall, specifically preventing Gram-positive bacteria from being able to build...
Antibiotics, also known as antibacterials, are types of medications that destroy or slow down the growth of bacteria. The Greek word anti means "against", and the Greek word bios means "life" (bacteria are life forms). Antibiotics are used to treat infections caused by bacteria. Bacteria are...
How do antibiotics affect bacterial cell walls?Antibiotics:Antibiotics are active substances that act against bacteria. Such substances are major agents that help to combat bacterial infections in individuals. The most common route of administration is oral. Once in the system, it starts its action ...
