Research in the Dick Lab
The lab’s focus is on the discovery of new preclinical development compounds against TB and Non-Tuberculous Mycobacterial (NTM) lung disease, including Mycobacterium abscessus and Mycobacterium avium. We apply a ‘compound first strategy’, i.e. we start with new chemical entities showing whole cell activity. This is followed by target deconvolution and hit-to-lead chemistry to deliver target-lead couples. In addition to de novo drug discovery, we carry our repositioning projects. Overall, we are prioritizing broad spectrum anti-mycobacterials active against both NTM and TB. NTM lung disease is depicted in Fig. 1. Fig. 2 shows a flow chart guiding compound progression.
