With the growing worldwide prevalence of antibiotic-resistant strains of tuberculosis (TB), new targets are urgently required for the development of treatments with novel modes of action. Fumarate hydratase (fumarase), a vulnerable component of the citric acid cycle in Mycobacterium tuberculosis (Mtb), is a metabolic target that could satisfy this unmet demand. A key challenge in the targeting of Mtb fumarase is its similarity to the human homolog, which shares an identical active site. A potential solution to this selectivity problem was previously found in a high-throughput screening hit that binds in a nonconserved allosteric site. In this work, a structure-activity relationship study was carried out with the determination of further structural biology on the lead series, affording derivatives with sub-micromolar inhibition. Further, the screening of this series against Mtb in vitro identified compounds with potent minimum inhibitory concentrations.

With the aim to discover orally active small molecules that stimulate glucose uptake, high throughput screening of a library of 5000 drug-like compounds was conducted in differentiated skeletal muscle cells in presence of insulin. N-Substituted phthalazinone acetamide was identified as a potential glucose uptake modulator. Several novel derivatives were synthesized to establish structure activity relationships. Identified lead thiazolyl- phthalazinone acetamide (7114863) increased glucose uptake (EC50 of 0.07 ± 0.02 μM) in differentiated skeletal muscle cells in presence of insulin. Furthermore, 7114863 was superior to rosiglitazone under similar experimental conditions without inducing PPAR-γ agonist activity thus making it a very interesting scaffold.
