comparison of V.A.C.® Granufoam Silver™ and V.A.C.® Granufoam™ loaded with a first-in-class bis-dialkylnorspermidine-terphenyl antibiofilm agent.

Implementation of negative pressure wound therapy (NPWT) as a standard of care has proven efficacious in reducing both the healing time and likelihood of nosocomial infection among pressure ulcers and traumatic, combat-related injuries. However, current formulations may not target or dramatically reduce bacterial biofilm burden following therapy. The purpose of this study was to determine the antibiofilm efficacy of an open-cell polyurethane (PU) foam (V.

Antibiofilm potential of a negative pressure wound therapy foam loaded with a first-in-class tri-alkyl norspermidine-biaryl antibiotic.

Negative-pressure wound therapy (NPWT) is commonly utilized to treat traumatic injuries sustained on the modern battlefield. However, NPWT has failed to decrease the incidence of deep tissue infections experienced by Wounded Warriors, despite attempts to integrate common antimicrobials, like Ag+ nanoparticles, into the wound dressing. The purpose of this study was to incorporate a unique antibiofilm compound (CZ-01179) into the polyurethane matrix of NPWT foam via lyophilized hydrogel scaffolding.

efficacy of a unique first-in-class antibiofilm antibiotic for biofilm-related wound infections caused by .

Wounds complicated by biofilms challenge even the best clinical care and can delay a return to duty for service members. A major component of treatment in wounded warriors includes infected wound management. Yet, all antibiotic therapy options have been optimized against planktonic bacteria, leaving an important gap in biofilm-related wound care.

Examination of a first-in-class bis-dialkylnorspermidine-terphenyl antibiotic in topical formulation against mono and polymicrobial biofilms.

Biofilm-impaired tissue is a significant factor in chronic wounds such as diabetic foot ulcers. Most, if not all, anti-biotics in clinical use have been optimized against planktonic phenotypes. In this study, an in vitro assessment was performed to determine the potential efficacy of a first-in-class series of antibiofilm antibiotics and compare outcomes to current clinical standards of care.

Unifying the Aminohexopyranose- and Peptidyl-Nucleoside Antibiotics: Implications for Antibiotic Design.

In search of new anti-tuberculars compatible with anti-retroviral therapy we re-identified amicetin as a lead compound. Amicetin's binding to the 70S ribosomal subunit of Thermus thermophilus (Tth) has been unambiguously determined by crystallography and reveals it to occupy the peptidyl transferase center P-site of the ribosome. The amicetin binding site overlaps significantly with that of the well-known protein synthesis inhibitor balsticidin S.
