Robertson Lab

Dr. Gregory Robertson’s research is focused on the field of Mycobacterium tuberculosis host-pathogen interactions with emphasis on the development of novel preclinical tools, use of TB mouse models for drug evaluation, and evaluation of drug activity and resistance in vitro and in vivo. He also leads preclinical animal studies as part of the Consortium for Applied Microbial Metrics including other investigators from the University of California San Francisco, Denver VA Medical Center, and CU Anschutz Medical Campus.

research project

TB Drug Accelerator

Goal: (i) To identify in vivo active compounds, (ii) to enable more effective hit-to-lead and lead optimization cycles, and (iii) to support the selection of pre-clinical candidates as a service for the TB Drug Accelerator researchers.

research project

Development of Novel Proteins Synthesis Inhibitors for MDR Tuberculosis

Goal: This proposal seeks to continue the development of the spectinamides as combination agents for MDR-TB, with a focus on their utility to treat chronic infections and as tools to understand the role of native efflux in tuberculosis drug persistence.

research project

Novel Spectinamide Antibiotics for the Treatment of MDR/XDR Tuberculosis

Goal: To develop an alternate MBX 4888 dosing route that is more amenable to outpatient dosing and patient compliance.

research project

Lead Optimization of Novel Azetidine Compound Series Demonstrating New Mechanism of Action for the Treatment of Tuberculosis

Goal: Development of novel tryptophan synthesis inhibitors with activity against M. tuberculosis in vivo.

research project

Validation of Mtb ribosomal RNA as a PD marker of treatment response

Goal: The primary output from this investment is the rapid and comprehensive characterization of novel RNA-based PD markers as measures of treatment-shortening potency.
