  1. aMtb. MIC is the minimum concentration required to inhibit growth of M. tuberculosis completely in liquid culture. MIC is the average of two independent experiments; b% inhibition of growth at 20 μM for compounds with MIC >20 μM.
  2. ND: not determined; cTC50 is the concentration required to inhibit growth of Vero cell line by 50%. TC50 is the average of two independent experiments.
