  Synthesis and biological evaluation of acyclic triaryl (Z)-olefins possessing a 3,5-di-tert-butyl-4-hydroxyphenyl pharmacophore: Dual inhibitors of cyclooxygenases and lipoxygenases

  摘要：

  A new class of regioisomeric acyclic triaryl (Z)-olefins possessing a 3,5-di-tert-butyl-4-hydroxyphenyl (DTBHP) 5-lipoxygenase (5-LOX) pharmacophore that is vicinal to a para-methanesulfonylphenyl cyclooxygenase-2 (COX-2) pharmacophore were designed for evaluation as selective COX-2 and/or 5-LOX inhibitors. The target compounds were synthesized via a highly stereoselective McMurry olefination cross-coupling reaction. This key synthetic step afforded a (Z):(E) olefinic mixture with a predominance for the (Z)-olefin stereoisomer. Structure-activity studies for the (Z)-1-(3,5-di-tert-butyl-4-hydroxyphenyl)-2-(4-methanesulfonylphenyl)-1-phenylalk-1-ene regioisomers showed that COX-1 inhibition decreased, COX-2 inhibition increased, and the COX-2 selectivity index (SI) increased as the chain length of the alkyl substituent attached to the olefinic double bond was increased (Et -> n-butyl -> n-heptyl). In this group of compounds, inhibition of both 5-LOX and 15-LOX was dependent upon the length of the alkyl substituent with the hex-1-ene compound 9c having a n-butyl substituent exhibiting potent inhibition of both 5-LOX (IC50 = 0.3 mu M) and 15-LOX (IC50 = 0.8 mu M) relative to the inactive (IC50 > 10 mu M) Et and n-heptyl analogs. Compound 9c is of particular interest since it also exhibits a dual inhibitory activity against the COX (COX-1 IC50 = 3.0 mu M, and COX-2 IC50 = 0.36 mu M, COX-2 SI = 8.3) isozymes. A comparison of the relative inhibitory activities of the two groups of regioisomers investigated shows that the regioisomers in which the alkyl substituent is attached to the same olefinic carbon atom (C-2) as the para-methanesulfonylphenyl moiety generally exhibit a greater potency with respect to COX-2 inhibition. The 4-hydroxy substituent in the 3,5-di-tert-butyl-4-hydroxyphenyl moiety is essential for COX and LOX inhibition since 3,5-di-tert-butyl-4-acetoxyphenyl derivatives were inactive inhibitors. These structure-activity data indicate acyclic triaryl (Z)-olefins constitute a suitable template for the design of dual COX-2/LOX inhibitors. (c) 2006 Elsevier Ltd. All rights reserved.

  Design and synthesis of acyclic triaryl (Z)-olefins: a novel class of cyclooxygenase-2 (COX-2) inhibitors

  摘要：

  A group of acyclic 2-alkyl-1, 1-diphenyl-2-(4-methylsulfonylphenyl)ethenes was designed for evaluation as selective cyclooxygenase-2 (COX-2) inhibitors. In vitro COX-1 and COX-2 isozyme inhibition structure-activity studies identified 1,1-diphenyl-2(4-methylsulfonylphenyl)hex-1-ene as a highly potent (IC50 = 0.014muM), and an extremely selective [COX-2 selectivity index (SI) >7142], COX-2 inhibitor that showed superior anti-inflammatory (A1) activity (ID50 = 2.5 mg/kg) relative to celecoxib (ID50 = 10.8mg/kg). This initial study was extended to include the design of a structurally related group of acyclic triaryl (Z)-olefins possessing an acetoxy (OAc) substituent at the para-position of the C-1 phenyl ring that is cis to a C-2 4-methylsulfonylphenyl substituent. COX-1 and COX-2 inhibition studies showed that (Z)-1-(4-acetoxyphenyl)-1-phenyl-2-(4-methylsulfonylphenyl)but-1-ene [(Z)-13b] is a potent (COX-1 IC50 = 2.4muM; COX-2 IC50 = 0.03 muM), and selective (COX-2 SI = 81), COX-2 inhibitor which is a potent AI agent (ID50 = 4.1 mg/kg) with equipotent analgesic activity to celecoxib. A molecular modeling (docking) study showed that the SO2Me substituent of (Z)-13b inserts deep inside the 2degrees-pocket of the COX-2 active site where one of the O-atoms of SO, group undergoes a H-bonding interaction with Phe(518). The p-OAc substituent on the C-1 phenyl ring is oriented in a hydrophobic pocket comprised of Met(522), Gly(526), Trp(387), Tyr(348), and Tyr(385), and the C-2 ethyl substituent is oriented towards the mouth of the COX-2 channel in the vicinity of amino acid residues Arg(12)0, Leu(531), and Val(349). Structure-activity data acquired indicate that a (Z)olefin having cis C-1 4-acetoxyphenyl (phenyl) and C-2 4-methylsulfonylphenyl substituents, and a C-1 phenyl substituent in conjunction with either a C-2 hydrogen or short alkyl substituent provides a novel template to design acyclic olefinic COX-2 inhibitors that, like aspirin, have the potential to acetylate COX-2.

  A new class of (E)-2-alkyl-2-(4-methanesulfonylphenyl)-1-phenylethenes were designed for evaluation as selective cyclooxygense-2 (COX-2) inhibitors. The target olefins were synthesized, via a Takeda olefination reaction, followed by oxidation of the respective thiomethyl olefinic intermediate. In vitro COX-1/COX-2 inhibition studies identified (E)-2-(4-methanesulfonylphenyl)-1-phenyloct-1-ene (8d) as a potent (IC50 = 0.77 muM) and selective (Selectivity Index > 130) COX-2 inhibitor.
