  Constrained Bithiazoles: Small Molecule Correctors of Defective ΔF508–CFTR Protein Trafficking

  摘要：

  Conformationally constrained bithiazoles were previously found to have improved efficacy over nonconstrained bithiazoles for correction of defective cellular processing of the ΔF508 mutant cystic fibrosis transmembrane conductance regulator (CFTR) protein. In this study, two sets of constrained bithiazoles were designed, synthesized, and tested in vitro using ΔF508-CFTR expressing epithelial cells. The SAR data demonstrated that modulating the constraining ring size between 7- versus 8-membered in these constrained bithiazole correctors did not significantly enhance their potency (IC50), but strongly affected maximum efficacy (Vmax), with constrained bithiazoles 9e and 10c increasing Vmax by 1.5-fold compared to benchmark bithiazole corr4a. The data suggest that the 7- and 8-membered constrained ring bithiazoles are similar in their ability to accommodate the requisite geometric constraints during protein binding.

• Potent <i>s-cis</i>-Locked Bithiazole Correctors of ΔF508 Cystic Fibrosis Transmembrane Conductance Regulator Cellular Processing for Cystic Fibrosis Therapy

  N-(5-(2-(5-Chloro-2-methoxyphenylamino)thiazol-4-yl)-4-methylthiazol-2-yl)pivalamide 1 (compound 15jf) was found previously to correct defective cellular processing of the cystic fibrosis protein Delta F508-CFTR. Eight C4'-C5 C,C-bond-controlling bithiazole analogues of 1 were designed, synthesized, and evaluated to establish that constraining rotation about the bithiazole-tethering has a significant effect on corrector activity. For example, constraining the C4'-C5 bithiazole tether in the s-cis conformation [N-(2-(5-chloro-2-methoxyphenylamino)-7,8-dihydro-6H-cyclohepta[1,2-d:3,4-d']bithiazole-2'-yl)pivalamide, 29] results in improved corrector activity. Heteroatom placement in the bithaizole core is also critical as evidenced by the decisive loss of corrector activity with s-cis constrained N-(2-(5-chloro-2-methoxyphenylamino)-5,6-dihydro-4H-cyclohepta[1,2-d:3,4-d]bithiazole-2'-yl)pivalamide 33. In addition, computational models were utilized to examine the conformational preferences for select model systems. Following our analysis, the "s-cis-locked" cycloheptathiazolothiazole 29 was found to be the most potent bithiazole corrector, with an IC(50) Of similar to 450 nM.
