Design of quinolinedione-Based geldanamycin analogues
摘要:
Quinoline-5,8-dione-based compounds were designed from the structure of the geldanamycin-bound Hsp-90 active site. The active site model predicted that aromatic substituents should be present at the 2-position, to take advantage of a hydrophobic pocket, and amino substituents should be present at the 6- or 7-position. COMPARE analysis revealed that the LC50 profile of 2-phenyl-6-(2-chloroethylamino)quinoline-5,8-dione has the highest geldanamycin-like activity (0.74 correlation coefficient). (C) 2003 Elsevier Ltd.

Silica gel supported nitric acid treatment of 2,5-dimethoxybenzaldehyde followed by reduction with iron powder provides 3,6-dimethoxy-2-aminobenzaldehyde. Friedlander condensation of this species with a variety of ketones and diketones leads to 5,8-dimethoxyquinoline derivatives which may be oxidized by ceric ammonium nitrate (CAN) and pyridine-2,6-dicarboxylic acid N-oxide (PDANO) to the corresponding quinones. The quinone functionality can be incorporated into larger cavities by a selective stepwise Friedlander approach and the CAN/PDANO oxidation appears to work preferentially for 5,8-dimethoxyquinoline.
