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).

2-Hydroxy-6-(1-(3-phenylurylphenyl)ethoxy)-benzaldehyde (2) has been synthesized in racemic form from 1,3-Dihydroxybenzene via formylation and reaction with 3-phenyluryl-methylbenzylbromide. The optically pure form of 2 was separated by normal silica colu
Controlling cis/trans-selectivity in intramolecular Diels-Alder reactions of benzo-tethered, ester linked 1,3,9-decatrienes

Predictions from DFT (B3LYP/6-31 G(d))-computed stereoisomer product distributions for intramolecular Diels-Alder (IMDA) reactions have been successfully replicated in the laboratory. Benzo-tethered hexadienyl acrylates generally undergo moderately trans-
Efficient and selective reduction protocols of the 2,2-dimethyl-1,3- benzodioxan-4-one functional group to readily provide both substituted salicylaldehydes and 2-hydroxybenzyl alcohols
Bajwa, Naval,Jennings, Michael P.
, p. 3646 - 3649 (2007/10/03)
Two complementary procedures have been developed that selectively allow for the synthesis of either substituted salicylaldehydes or the corresponding 2-hydroxylbenzyl alcohols upon treatment of the 2,2-dimethyl-1,3-benzodioxan-4- one functional group with DIBAL-H or LAH, respectively.
Regioselective synthesis of 6-substituted 2-hydroxybenzaldehyde: Efficient synthesis of the immunomodulator tucaresol and related analogues
Zacharie, Boulos,Attardo, Giorgio,Barriault, Nancy,Penney, Christopher
, p. 2925 - 2929 (2007/10/03)
Two new improved procedures have been developed for the preparation of the immunostimulant tucaresol 1 [4-(2-formyl-3-hydroxyphenoxymethyl)benzoic acid]. These approaches, which start from resorcinol or 2,6-dimethoxybenzaldehyde, are practical and therefore amenable to scale-up. In the case of the second approach, the multi-step synthesis reported in the literature has been reduced to three steps. Furthermore, unlike the reported method, our synthesis is versatile for the preparation of tucaresol analogues. The method is general and applicable for the preparation of 6-substituted 2-hydroxybenzaldehydes.
