Gelain A, Barlocco D, Kwon BM, Jeong TS, Im KR, Legnani L, Toma L: Biphenyl versus phenylpyridazine derivatives: the role of the heterocycle in a series of acyl-CoA:cholesterol acyl transferase inhibitors. J Med Chem. 2008 Mar 13;51(5):1474-7. Epub 2008 Feb 20.
A series of alkylamido- ( 1) and alkylaminobiphenyl ( 2) derivatives were synthesized as possible bioisosters of the reported ACAT inhibitors phenylpyridazine analogues ( I). Both 1 and 2 were tested on the human ACAT-1 and ACAT-2 isoforms. The amino derivatives 2 were found to be inactive, contrary to the related pyridazine derivatives. By contrast, the ortho -substituted amides 1a and 1d showed an interesting activity. These results support the essential role of the pyridazine nucleus. Modeling studies were also performed. |
