Biological Activity

Description Clindamycin inhibits protein synthesis by acting on the 50S ribosomal, used for the treatment of bacterial infections.
In vitro
In vitro Clindamycin is a semisynthetic analogue of lincomycin. Clindamycin primarily inhibits the initiation of peptide chain synthesis by deregulating enzyme-catalyzed initiation of peptide bounds. Clindamycin appears to have a modest effect on protein synthesis by certain mammalian cells. [1] Clindamycin is active against most gram-positive aerobic bacteria. Clindamycin is about eight times more active than lincomycin against Staphylococcus aureus and Streptococcus pneumonia. Clindamycin is four times more active than erythromycin against S. aureus and is active even against strains that are resistant to erythromycin, penicillin, and methicillin. Clindamycin is active against gram-positive anaerobes. Clindamycin highly activates against Bacteroides specie. [2] Clindamyci also alters the bacterial surface in such a way that phagocytosis and intracellular killing of the bacteria is greatly facilitated. Clindamycin potentiates opsonization and phagocytosis. [4]
In Vivo
In vivo Clindamycin (50mg/kg daily administrated by intramuscular) increases the survival rate of monkeys infected with penicillin-resistant S. aureu to 87.5% (7/8). [5] Clindamycin (40 mg/kg administrated three times daily) protects 87.5% (7/8) of rabbits from anaerobic pulmonary infections induced by transtracheal inoculation of a mixture of B. fragillis, Streptococcus morbillorm, Fusobacterium nucleatum and Eubacterium lentum. [6] Clindamycin (400 mg/kg treated by mixed in the diet) increases survival rate of mice infected with the Toxoplasma gondii to 100%, while all animals die in untreated group. [7]

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
