clindamycine brands

Molecular formula: C18H33ClN2O5S

Clindamycin inhibits bacterial protein synthesis by binding to 23S RNA of the 50S subunit of the bacterial ribosome. It impedes both the assembly of the ribosome and the translation process. The molecular mechanism through which this occurs is thought to be due to clindamycin's three-dimensional structure, which closely resembles the 3'-ends of L-Pro-Met-tRNA and deacylated-tRNA during the peptide elongation cycle - in acting as a structural analog of these tRNA molecules, clindamycin impairs peptide chain initiation and may stimulate dissociation of peptidyl-tRNA from bacterial ribosomes. The mechanism through which topical clindamycin treats acne vulgaris is unclear, but may be related to its activity against _Propionibacterium acnes_, a bacteria that has been associated with acne. Clindamycin may be bacteriostatic or bactericidal in action, depending on the concentration of the drug attained at the site of infection and the susceptibility of the infecting organism. Clindamycin palmitate hydrochloride and clindamycin phosphate are inactive until hydrolyzed to free clindamycin. This hydrolysis occurs rapidly in vivo. Clindamycin appears to inhibit protein synthesis in susceptible organisms by binding to 50S ribosomal subunits; the primary effect is inhibition of peptide bond formation. The site of action appears to be the same as that of erythromycin, chloramphenicol, and lincomycin. Clindamycin binds exclusively to the 50S subunit of bacterial ribosomes and suppresses protein synthesis. ... Clindamycin is not a substrate for macrolide efflux pumps, and strains that are resistant to macrolides by this mechanism are susceptible to clindamycin.
