Higher Affinity Quadruply Hydrogen-Bonded Complexation with 7-Deazaguanine Urea
摘要:
UG forms a highly stable quadruply hydrogen-bonded heterocomplex with DAN, but the fidelity of the complex is lowered somewhat by the Hoogsteen-side oligornerization of UG (K-assoc similar to 230 M-1, CDCl3). DeUG was prepared as a more robust analogue of UG lacking the Hoogsteen nitrogen atom. Remarkably, the deaza analogue, DeUG, forms a much more stable complex with DAN (> 10-fold higher K-assoc for DeUG.DAN vs UG.DAN) but also dimerizes more strongly (K-dim = 880 +/- 40 M-1, CDCl3) by adopting a conformation preorganized for both binding and dimerization.

The invention is directed to 6-(4-pyιϊmidinyl)-1 H-indazole derivatives. Specifically, the invention is directed to compounds according to Formula (I) wherein R1 - R4 are defined herein. The compounds of the invention are inhibitors of PDK1 and can be useful in the treatment of immune and metabolic diseases and disorders characterized by constitutively activated ACG kinases such as cancer and more specifically cancers of the breast, colon, and lung. Accordingly, the invention is further directed to pharmaceutical compositions comprising a compound of the invention. The invention is still further directed to methods of inhibiting PDK1 activity and treatment of disorders associated therewith using a compound of the invention or a pharmaceutical composition comprising a compound of the invention.
