Article Abstract:

The enzyme dihydrofolate reductase from M. tuberculosis (MtDHFR) have high untapped potential to be a target for new drugs against tuberculosis, due to its importance and uniqueness for this pathogen. Preliminary studies have obtained fragment-like molecules with low affinity to MtDHFR which can potentially become lead compounds. Taking this into account, the fragment MB872 was used as a prototype for analogue development by bioisosterism/retro-bioisosterism, which resulted in 20 new substituted 3-benzoic acid derivatives. Compounds were active against MtDHFR, with IC₅₀ ranging from 7 to 40 μM, where compound 4e not only had the best inhibitory activity (IC₅₀ = 7 μM), but also was 71-fold more active than the original fragment MB872. The 4e inhibition kinects revealed a known uncompetitive mechanism, which was supported by molecular modeling suggestion that the compounds can access an unique back-pocket. Thus, based on these results, substituted 3-benzoic acid derivatives have strong potential to be developed as novel MtDHFR inhibitors and also anti-TB agents.
