General description

Chemical structure: macrolide

Application

Clindamycin is used to study bacterial infections, such as group B streptococcal disease, bacterial resistance and plasma protein binding.
Used to study bacterial protein synthesis.

Biochem/physiol Actions

Clindamycin hydrochloride is highly effective against anaerobic species.
Clindamycin is a semi-synthetic, lincosamide antibiotic that is prepared from lincomycin. It inhibits bacterial protein synthesis by hydrogen bond interactions with the 23S rRNA component of the 50S ribosomal subunit thus inducing dissociation of the peptidyl-t-RNA complex. It has antibacterial activity against Gram-positive cocci and antiprotozoal activity against Taxoplasma.

Other Notes

Antibacterial and antiprotozoal antibiotic of the lincosamide class.
Keep container tightly closed in a dry and well-ventilated place.

Lincomycin and clindamycin are lincosamide antibiotics used in clinical practice. Both antibiotics are bacteriostatic and inhibit protein synthesis in sensitive bacteria. They may even be bactericidal at the higher concentrations that can be reached in vivo. Clindamycin is usually more

although plasma protein binding (PPB) is accepted to be an essential factor in reducing antimicrobial activity, little is known about the underlying mechanisms. One possibility includes impaired penetration of an antimicrobial into bacterial cells in the presence of PPB. As
