chlorhexidine

Chlorhexidine (Rotersept) is a biguanide compound used as an antiseptic agent with topical antibacterial activity. Chlorhexidine is positively charged and reacts with the negatively charged microbial cell surface, thereby destroying the integrity of the cell membrane. Subsequently, chlorhexidine penetrates into the cell and causes leakage of intracellular components leading to cell death. Since gram-positive bacteria are more negatively charged, they are more sensitive to this agent.

Chlorhexidine diacetate (Bactigras) is a disinfectant and topical anti-infective agent used also as mouthwash to prevent oral plaque.

Chlorhexidine dihydrochloride (NSC-185) is a disinfectant and topical anti-infective agent used also as mouthwash to prevent oral plaque.

Chlorhexidine digluconate is a broad-spectrum antiseptic and disinfectant with broad-spectrum antimicrobial activity, inhibits both Gram-positive and Gram-negative bacteria, induces necrosis and apoptosis, and can be used in the study of bacterial infections.

Chlorhexidine-d8 is intended for use as an internal standard for the quantification of chlorhexidine by GC- or LC-MS. Chlorhexidine is a bis(biguanide) antimicrobial disinfectant and antiseptic agent. It inhibits growth of clinical methicillin-resistant S. aureus (MRSA) isolates (MIC90 = 4 μg ml). It is also active against canine isolates of MRSA, methicillin-susceptible S. aureus (MSSA), methicillin-resistant S. pseudintermedius (MRSP), and methicillin-susceptible S. pseudintermedius (MSSP; MIC90s = 4, 2, 2, and 1 mg L, respectively). Chlorhexidine inhibits growth of E. faecium strains (MICs = 1.2-19.6 μg ml) and C. albicans (MIC = 5.15 μg ml). It generates cations that bind to and destabilize the bacterial cell wall to induce death.6 Chlorhexidine also completely inhibits matrix metalloproteinase-2 (MMP-2) and MMP-9 when used at concentrations of 0.0001 and 0.002%, respectively, in a gelatin degradation assay. Formulations containing chlorhexidine have been used in antisept......

Meclocycline is a tetracycline antibiotic with broad antimicrobial activity. Meclocycline inhibits lactate dehydrogenase (LDH) release and cell toxicity induced by expression of htt-N63-148Q, a mutant form of the huntingtin gene, without altering htt-N63-148Q protein levels in PC12 cells.
