What is Clindamycin?

Plain description, key identifiers and synonyms

Clindamycin is a semisynthetic broad spectrum antibiotic produced by chemical modification of the parent compound lincomycin. Clindamycin dissociates peptidyl-tRNA from the bacterial ribosome, thereby disrupting bacterial protein synthesis. (NCI04)

Roles

  • environmental contaminant
  • xenobiotic

Pharmacology

Clindamycin is a Lincosamide Antibacterial. The physiologic effect of clindamycin is by means of Decreased Sebaceous Gland Activity and Neuromuscular Blockade.

How it is made

Lincomycin is treated with a solution of Rydon reagent prepared from triphenylphosphine, acetonitrile, and chlorine. The base is ultimately reacted with hydrochloric acid.

First resulted from the reaction of lincomycin and thionyl chloride, improved synthetic methods involve the reaction of lincomycin and triphenylphosphine dichloride or triphenylphosphine in carbon tetrachloride.

Synthesized ... by introducing a chlorine atom at the 7 position of lincomycin.
