Synthesis and Evaluation of Heteroaryl-Substituted Dihydronaphthalenes and Indenes: Potent and Selective Inhibitors of Aldosterone Synthase (CYP11B2) for the Treatment of Congestive Heart Failure and Myocardial Fibrosis
摘要:
In this study, the synthesis and biological evaluation of heteroaryl-substituted dihydronaphthalenes and indenes (1-16) is described. The compounds were tested for activity by use of human CYP11B2 expressed in fission yeast and V79 MZh cells and for selectivity by use of human CYP11B1, CYP17, and CYP19. The most active inhibitor was the 6-methoxydihydronaphthalene 4 (IC50 = 2 nM), showing a K-i value of 1.3 nM and a competitive type of inhibition. The 5-methoxyindene 3 was found to be the most selective CYP11B2 inhibitor (IC50 = 4 nM; CYP11B1 IC50 = 5684 nM), which also showed only marginal inhibition of human CYP3A4 and CYP2D6. Docking and molecular dynamics studies using our homology-modeled CYP11B2 structure were performed to understand some structure-activity relationships. Caco-2 cell experiments revealed highly cell-permeable compounds, and metabolic studies with 4 using rat liver microsomes showed sufficient stability.

3-(1-imidazolyl)chroman-4-ones and 2-(1-imidazolyl)-1-tetralones II, some of their alcohols, and some relatedcompounds were synthesized and tested for hypolipidemic activity. CompoundsII, bearing appropriate lipophilic substituents on the phenyl ring, strongly reduced total serum cholesterol while raising high-density lipoprotein cholesterol in diet-induced hypercholesterolemic rats. 3-(1-Imidazolyl)chroman-4-ols

The compounds were tested in vitro for inhibition of the three target enzymes P450arom (human placental microsomes), P45017 (rat testicular microsomes), and P450TxA2 (citrated human whole blood). To examine selectivity, some compounds were further tested in vitro for inhibition of P450 18 (bovine adrenal mitochondria), P450 see (bovine adrenal mitochondria) and corticoid formation (aldosterone, corticosterone;
Compounds of the general formulae: ##STR1## in which Ar and Ar.sup.1 which may be the same or different represent aromatic radicals optionally substituted once or more than by substituents selected from halogen, lower alkyl and lower alkoxy and Alk represents an alkylene group containing from 1 to 4 carbon atoms which alkylene group may be interrupted with a heteroatom; and acid addition salts thereof. These compounds have anti-anaerobe and also anti-fungal activity and are non-mutagenic.
