Mono- or Diphenylpyridazines Connected to N-(2,4-Difluorophenyl)-N‘-heptylurea as Acyl-CoA:Cholesterol Acyltransferase Inhibitors
摘要:
Mono- and diphenylpyridazine ureido derivatives, structurally related to DuP 128, were synthesized and tested for their inhibitory activity against ACAT isolated from rat liver microsomes. Several compounds displayed ACAT inhibition in the micromolar range. The amino derivatives 4a-c were also tested against hACAT-1 and hACAT-2 isoforms. They retained the same trend shown in the previous assay. Modeling studies on representative terms were performed. Significant similarities between the geometrical features of the model DuP 128 and the most active pyridazine derivatives were observed.

Acyl-CoA:cholesterol acyltransferase (E.C.2.3.1.26, ACAT) is a microsomial enzyme that catalyses the formation of cholesteryl esters by acylation of cholesterol with long chain fatty acylCoA [1].

A series of N-(2,4-difluorophenyl)-N’-heptyl-N’-4-[(substituted)-pyridazin-3-yl)thio]pentyl}urea derivatives having a phenyl ring at positions 5 and/or at position 6 of the heterocycle, as well as the corresponding sulfones, were synthesized. Their inhibitory activity against acyl-CoA:cholesterol acyltransferase (ACAT) was tested on the enzyme prepared from rat liver microsomes. Theoretical studies were performed to correlate their activity to their structural features.
