2. Streptogramin A - Wikipedia

   en.wikipedia.org/wiki/Streptogramin_A

   Streptogramin A is a group of antibiotics within the larger family of antibiotics known as streptogramins.They are synthesized by the bacteria Streptomyces virginiae. [1] The streptogramin family of antibiotics consists of two distinct groups: group A antibiotics contain a 23-membered unsaturated ring with lactone and peptide bonds while group B antibiotics are depsipeptides (lactone-cyclized ...

3. Daptomycin - Wikipedia

   en.wikipedia.org/wiki/Daptomycin

   Daptomycin has a distinct mechanism of action, disrupting multiple aspects of bacterial cell membrane function. It inserts into the cell membrane in a phosphatidylglycerol-dependent fashion, where it then aggregates. The aggregation of daptomycin alters the curvature of the membrane, which creates holes that leak ions.

4. Mechanism of action - Wikipedia

   en.wikipedia.org/wiki/Mechanism_of_action

   This differs from a mechanism of action since it is a more specific term that focuses on the interaction between the drug itself and an enzyme or receptor and its particular form of interaction, whether through inhibition, activation, agonism, or antagonism. Furthermore, the term "mechanism of action" is the main term that is primarily used in ...

5. Colistin - Wikipedia

   en.wikipedia.org/wiki/Colistin

   Colistin, also known as polymyxin E, is an antibiotic medication used as a last-resort treatment for multidrug-resistant Gram-negative infections including pneumonia. [7] [8] These may involve bacteria such as Pseudomonas aeruginosa, Klebsiella pneumoniae, or Acinetobacter. [9]

6. Puromycin - Wikipedia

   en.wikipedia.org/wiki/Puromycin

   The exact mechanism of action is unknown at this time but the 3' position contains an amide linkage instead of the normal ester linkage of tRNA. That makes the molecule much more resistant to hydrolysis and stops the ribosome. Puromycin is selective for either prokaryotes or eukaryotes. Also of note, puromycin is critical in mRNA display.

7. Mode of action - Wikipedia

   en.wikipedia.org/wiki/Mode_of_action

   A mechanism of action of a chemical could be "binding to DNA" while its broader mode of action would be "transcriptional regulation". [3] However, there is no clear consensus and the term mode of action is also often used, especially in the study of pesticides, to describe molecular mechanisms such as action on specific nuclear receptors or ...
