Ceragenins, a novel family of antibiotics, are cationic derivatives of cholic acid and display broad-spectrum antimicrobial activities. Multiple ceragenins have been synthesized and studied, and most published data are with ceragenin CSA-13.

Design and Synthesis of Ceragenins–Cationic Steroid Antimicrobial Compounds, Structural Improvement and Synthesis of Cyclopentenone Prostaglandins and Modification and Synthesis of Derivatives of Ribityllumazines: Potential Antigens for Activation of MAIT Cells [PDF]
Antimicrobial peptides (AMPs) are ubiquitous and display broad-spectrum antimicrobial activity that can control bacterial colonization of surfaces. Ceragenins are small-molecule mimics of AMPs and have several advantages over AMPs, including cost of ...

Susceptibility of Colistin-Resistant, Gram-Negative Bacteria to Antimicrobial Peptides and Ceragenins [PDF]
ABSTRACT The susceptibility of colistin-resistant clinical isolates of Klebsiella pneumoniae to ceragenins and antimicrobial peptides (AMPs) suggests that there is little to no cross-resistance between colistin and ceragenins/AMPs and that lipid A modifications are found in bacteria with modest changes in ...

Cells were grown in C+Y at 37°C to an A550 of about 0.2. CSA-13 was then added to an aliquot of the culture and incubation continued without shaking at 37°C. Solid circles represent untreated control cultures. CSA-13 was added (open symbols) at 2.5 µg/ml

One current problem in medicine is the accumulation of biofilm on medical devices. Bacterial colonization of endotracheal tubes and urinary catheters is the leading cause of hospital-acquired infections.

Ceragenins are cationic bile salt derivatives having antimicrobial activity. The interactions of several ceragenins with phospholipid bilayers were tested in different systems. The ceragenins are capable of forming specific associations with several phospholipid species that may be involved with their antimicrobial action.

Cationic steroid antimicrobials (CSA-ceragenin) are a new class of antimicrobial agent. In vitro activities of CSA-8, CSA-13, CSA-44, CSA-131, and CSA-138 and amphotericin B (AMP-B) were assessed against 50 nonrepeat Candida spp.

Selective Nanoparticles for Antimicrobial Therapies and MRI Diagnostics [PDF]
Early diagnosis and treatment of an infection and the selectivity of the treatment method are three parameters, which if optimized will greatly enhance a patient’s prognosis.

Cationic steroid antimicrobials (CSAs or ceragenins) are a novel class of synthetic, cholic acid-based mimics of endogenous antimicrobial peptides. These small molecule compounds display broad bactericidal activity against gram-negative and gram-positive

Effect of CSA-13 on streptococcal species.
Exponentially growing cultures were incubated in C+Y to an A550 of about 0.2. CSA-13 was then added to aliquots of the cultures and incubation continued without shaking at 37°C. (a) S. pneumoniae R6. (b) S. pneumoniae Spain23F-1.
