Abstract

ABSTRACTThe recent development and spread of extensively drug-resistant and totally drug-resistant resistant (TDR) strains of Mycobacterium tuberculosishighlight the need for new antitubercular drugs. Protein synthesis inhibitors have played an important role in the treatment of tuberculosis (TB) starting with the inclusion of streptomycin in the first combination therapies. Although parenteral aminoglycosides are a key component of therapy for multidrug-resistant TB, the oxazolidinone linezolid is the only orally available protein synthesis inhibitor that is effective against TB. Here, we show that small-molecule inhibitors of aminoacyl-tRNA synthetases (AARSs), which are known to be excellent antibacterial protein synthesis targets, are orally bioavailable and effective against M. tuberculosisin TB mouse infection models. We applied the oxaborole tRNA-trapping (OBORT) mechanism, which was first developed to target fungal cytoplasmic leucyl-tRNA synthetase (LeuRS), to M. tuberculosisLeuRS. X-ray crystallography was used to guide the design of LeuRS inhibitors that have good biochemical potency and excellent whole-cell activity against M. tuberculosis. Importantly, their good oral bioavailability translates into in vivoefficacy in both the acute and chronic mouse models of TB with potency comparable to that of the frontline drug isoniazid.

19. Discovery of a Novel Class of Boron-Based Antibacterials with Activity against Gram-Negative Bacteria

Abstract

ABSTRACTGram-negative bacteria cause approximately 70% of the infections in intensive care units. A growing number of bacterial isolates responsible for these infections are resistant to currently available antibiotics and to many in development. Most agents under development are modifications of existing drug classes, which only partially overcome existing resistance mechanisms. Therefore, new classes of Gram-negative antibacterials with truly novel modes of action are needed to circumvent these existing resistance mechanisms. We have previously identified a new a way to inhibit an aminoacyl-tRNA synthetase, leucyl-tRNA synthetase (LeuRS), in fungi via the oxaborole tRNA trapping (OBORT) mechanism. Herein, we show how we have modified the OBORT mechanism using a structure-guided approach to develop a new boron-based antibiotic class, the aminomethylbenzoxaboroles, which inhibit bacterial leucyl-tRNA synthetase and have activity against Gram-negative bacteria by largely evading the main efflux mechanisms in Escherichia coliand Pseudomonas aeruginosa. The lead analogue, AN3365, is active against Gram-negative bacteria, including Enterobacteriaceaebearing NDM-1 and KPC carbapenemases, as well as P. aeruginosa. This novel boron-based antibacterial, AN3365, has good mouse pharmacokinetics and was efficacious against E. coliand P. aeruginosain murine thigh infection models, which suggest that this novel class of antibacterials has the potential to address this unmet medical need.

Abstract

Objectives: To understand the current use of electronic health records (EHRs) in small primary care practices and to explore experiences and perceptions of physicians and staff toward the benefits, challenges, and successful strategies for implementation and meaningful use of advanced EHR functions., Study Design: Qualitative case study of 6 primary care practices in Virginia., Methods: We performed surveys and in-depth interviews with clinicians and administrative staff (N = 38) and observed interpersonal relations and use of EHR functions over a 16-month period. Practices with an established EHR were selected based on a maximum variation of quality activities, location, and ownership., Results: Physicians and staff report increased efficiency in retrieving medical records, storing patient information, coordination of care, and office operations. Costs, lack of knowledge of EHR functions, and problems transforming office operations were barriers reported for meaningful use of EHRs. Major disruption to patient care during upgrades and difficulty utilizing performance tracking and quality functions were also reported. Facilitators for adopting and using advanced EHR functions include team-based care, adequate technical support, communication and training for employees and physicians, alternative strategies for patient care during transition, and development of new processes and work flow procedures., Conclusions: Small practices experience difficulty with implementation and utilization of advanced EHR functions. Federal and state policies should continue to support practices by providing technical assistance and financial incentives, grants, and/or loans. Small practices should consider using regional extension center services and reaching out to colleagues and other healthcare organizations with similar EHR systems for advice and guidance.
