  ISOFLAVANS DERIVATIVES AS INHIBITORS OF SOYBEAN LIPOXYGENASE: IN-VITRO AND DOCKING STUDIES

  摘要：

  The lipoxygenases (LOX) are a family of non-heme iron-containing dioxygenases which catalyze the stereospecific insertion of molecular oxygen lino arachidonic acid, leading to hydroxy derivatives as end products. In this work, we studied the behavior of seven isoflavans on 15-soybean lipoxygenases (15-sLOX), comparing them with the known inhibitors quercetin and 3,4-dihydroxybenzoic acid. Four of the seven investigated isoflavans showed IC50 values smaller than 50 mu M, being more potent than quercetin or 3, 4-dihydroxybenzoic acid. Besides a catecholic pattern, the presence of an aromatic ring B seems to confer additional activity to these compounds, a result which was rationalized by docking studies of these isoflavanss into the enzyme binding site.

  Continuing our search to find more potent and selective 5‐LOX inhibitors, we present now the enzymatic evaluation of seventeen isoflavones (IR) and nine isoflavans (HIR), and their in vitro and in cellulo potency against human leukocyte 5‐LOX. Of the 26 compounds tested, 10 isoflavones and 9 isoflavans possessed micromolar potency, but only three were selective against 5‐LOX (IR‐2, HIR‐303, and HIR‐309), with IC50 values at least 10 times lower than those of 12‐LOX, 15‐LOX‐1, and 15‐LOX‐2. Of these three, IR‐2 (6,7‐dihydroxy‐4‐methoxy‐isoflavone, known as texasin) was the most selective 5‐LOX inhibitor, with over 80‐fold potency difference compared with other isozymes; Steered Molecular Dynamics (SMD) studies supported these findings. The presence of the catechol group on ring A (6,7‐dihydroxy versus 7,8‐dihydroxy) correlated with their biological activity, but the reduction of ring C, converting the isoflavones to isoflavans, and the substituent positions on ring B did not affect their potency against 5‐LOX. Two of the most potent/selective inhibitors (HIR‐303 and HIR‐309) were reductive inhibitors and were potent against 5‐LOX in human whole blood, indicating that isoflavans can be potent and selective inhibitors against human leukocyte 5‐LOX in vitro and in cellulo.
