We report the discovery of a new potent allosteric effector of sickle cell hemoglobin, GBT440 (36), that increases the affinity of hemoglobin for oxygen and consequently inhibits its polymerization when subjected to hypoxic conditions. Unlike earlier allosteric activators that bind covalently to hemoglobin in a 2:1 stoichiometry, 36 binds with a 1:1 stoichiometry. Compound 36 is orally bioavailable and partitions highly and favorably into the red blood cell with a RBC/plasma ratio of ~150. This partitioning onto the target protein is anticipated to allow therapeutic concentrations to be achieved in the red blood cell at low plasma concentrations. GBT440 (36) is in Phase 3 clinical trials for the treatment of sickle cell disease (NCT03036813).

N-Myristoyltransferase (NMT) represents an attractive drug target in parasitic infections such as malaria due to its genetic essentiality and amenability to inhibition by drug-like small molecules. Scaffold simplification from previously reported inhibitors containing bicyclic cores identified phenyl derivative 3, providing a versatile platform to study the effects of substitution on the scaffold, which yielded pyridyl 19. This molecule exhibited improved enzyme and cellular potency, and reduced lipophilicity compared to inhibitor 3. Further structure-based inhibitor design led to the discovery of 30, the most potent inhibitor in this series, which showed single-digit nM enzyme affinity and sub-μM anti-plasmodial activity.

Bis-8-hydroxyquinoline substituted benzylamines have been synthesized and screened for their antitumor activity on KB3 cell line model. Synthesis of this series of new analogues was accomplished using a one pot specific methodology which allows the synthesis of both bis- and mono-8-hydroxyquinoline substituted benzylamines. Among the synthesized compounds two compounds (4a and 5a), respectively, named JLK 1472 and JLK 1486, were particularly potent on KB3 cell line. Their CC50 values being, respectively, 2.6 and 1.3 nM. Screened on a panel of cell lines showing various phenotype alterations, both compounds were found inactive on some cell lines such as PC3 (prostate cell line) and SF268 (neuroblastoma cell line) while highly active on other different cell lines. Mechanistic studies reveal that these two analogues did not affect tubulin and microtubules neither they exert a proteasomal inhibition effect. In contrast 4a and 5a activate specifically caspase 3/7 and not caspase 8 and 9, suggesting that their biological target should be located upstream from caspase 3/7. Moreover their cytotoxic effect is potentiated by the pro-apoptotic effects of TRAIL.
