[EN] INDOLINES AS PROTAC COMPOUNDS [FR] INDOLINES UTILISÉES EN TANT QUE COMPOSÉS PROTAC
摘要:
The present invention relates to compounds of Formula (I) that target PMS2, a component of DNA Mismatch Repair (MMR) wherein R2, R4, R6, A1, A2, A4, L and Q are each as defined herein. The present invention also relates to processes for the preparation of these compounds, to pharmaceutical compositions comprising them, and to their use in the treatment of proliferative disorders, such as cancer, as well as other diseases or conditions in which PMS2 is implicated.
Lack of Effect of the Length of Oligoglycine- and Oligo(ethylene glycol)-Derived para-Substituents on the Affinity of Benzenesulfonamides for Carbonic Anhydrase II in Solution
摘要:
Using H-1 NMR spectroscopy, values of T-2 have been determined for the methylene protons of the oligoglycine moieties of para-substituted benzenesulfonamides having structures H2NO2SC6H4CO(Gly)(n)OH (n = 1-6) bound at the active site of bovine carbonic anhydrase II (CA, EC 4.2.1.1). These values have been correlated with measurements of dissociation constants of these complexes, in order to infer motion of these ligands when bound to the enzyme. Motion of glycines 1-3 (those closest to the aryl ring) is hindered by their proximity to the protein; motion of glycines 4-6 is relatively unhindered. Despite the restriction to motion inferred for glycines 1-3, the values of K-d for the six compounds (n = 1-6, 1-6) are indistinguishable within experimental uncertainty (+/-20%): K-d in mu M (n) 0.30 (1); 0.26 (2); 0.33 (3); 0.37 (4); 0.37 (5); 0.34 (6). There is, therefore, an unexpected compensation of the loss in conformational entropy on binding by another contributor to the free energy.
