BMH-21,896705-16-1

别名

N-[2-(Dimethylamino)ethyl]-12-oxo-2H-benzo[g]pyrido[2,1-b]quinazoline-4-carboxamide

一般描述

BMH-21 is a planar heterocyclic small molecule DNA intercalator.

生化/生理作用

BMH-21 has the ability to bind ribosomal DNA and prevent RNA polymerase I (Pol I) transcription and results in the disintegration of the nucleolus. It does not impair DNA damage detection. BMH-21 is considered as an important activator of the p53 pathway. BMH-21 is a potent inhibitor of RNA Pol I. BMH-21 binds strongly to GC-rich DNA sequences, ultimately inhibiting RNA Pol I, blocking transcription and disrupting the nucleolar structure. BMH-1 causes dissociation of the RPA194 catalytic subunit from Pol I, and disassembly of Pol I:DNA complexes. The compound BMH-21 inhibits proliferation of a broad range of tumor cell lines.
