Novel 1H-benzimidazol-4-ols with potent 5-lipoxygenase inhibitory activity
摘要:
The synthesis and structure--activity profile of 2-substituted benzimidazol-4-ols as inhibitors of cell-free RBL-1 5-lipoxygenase are discussed, and their potency is compared with that of the standard inhibitors phenidone, AA 861, BW 755C, and nordihydroguaiaretic acid. In contrast to the standard compounds, most did not inhibit the release of slow-reacting substance of anaphylaxis (SRS-A) in vivo when administered at 200 microM ip to rats subjected to peritoneal anaphylaxis, although five compounds containing a methoxylated benzyl group (compounds 36, 39, 42, and 43) or hydroxylated benzyl group (41) showed similar activity to that of phenidone, nordihydroguaiaretic acid, and AA 861. Of the many compounds tested, two, 5-tert-butyl-7-methyl-2-(trifluoromethyl)-1H-benzimidazol-4-ol (57) and 2-(4-methoxybenzyl)-7-methyl-1H-benzimidazol-4-ol (36), like dexamethasone, inhibited monocyte accumulation in a pleural exudate model of inflammation. Standard lipoxygenase inhibitors such as phenidone, BW 755C, and AA 861 were inactive in this system.

is N-containing heterocyclic ring optionally substituted with one or more suitable substituent(s),
R
2
is hydroxyamino,
R
3
is hydrogen or a suitable substituent,
L
1
is —(CH
2
)
n
— (wherein n is an integer of 0 to 6) optionally substituted with one or more suitable substituent(s), wherein one or more methylene(s) may be replaced with suitable heteroatom(s), and
L
