As part of a programme to discover novel transcription factor inhibitors, a 40-membered library of tetracycline analogues was screened to identify potential HIF-1 inhibitors. Two novel analogues (5b and 5c) with significant HIF-1 modulation properties were identified. These molecules possess good cellular penetration properties, and provide significant down-regulation of VEGF in U251 cells.
