  Design, Synthesis, and Structure−Activity Relationship Studies of 3,4,6-Triphenylpyran-2-ones as Selective Cyclooxygenase-2 Inhibitors

  摘要：

  A group of regioisomeric 3,4,6-triphenylpyran-2-ones with a MeSO2 pharmacophore at the paraposition of either a C-3 phenyl or a C-4 phenyl substituent on the central six-membered pyran-2-one ring were prepared and evaluated in vitro for their abilities to inhibit the isozymes COX-1 and COX-2. Structure-activity relationship (SAR) data, acquired by substituent modification at the para-position of the C-6 phenyl ring attached to the central pyranone, showed that 6-(4-methoxyphenyl)-3-(4-methanesulfonylphenyl)-4-phenylpyran-2-one (12e) was the most potent and selective COX-2 inhibitor (COX-2 IC50 = 0.02 muM; COX-1 IC50 > 100 muM) with a high COX-2 selectivity index (SI > 5000) relative to the reference drugs celecoxib (COX-2 IC50 = 0.07 muM; SI = 474) and rofecoxib (COX-2 IC50 = 0.50 muM; SI > 200). 6-(4-Methoxyphenyl)-3-(4-methanesulfonylphenyl)-4-phenylpyran-2-one (12e) was a more potent oral antiinflammatory agent (ID50 = 5.6 mg/kg) than celecoxib (ID50 = 10.8 mg/kg) in a carrageenan-induced rat paw edema assay. In a 4% NaCl-induced abdominal constriction assay, a 5 mg/kg oral dose of 12e exhibited good analgesic activity at different time intervals producing 37.5 and 69% inhibition of writhing at 30 and 60 min, respectively. In contrast, the corresponding 6-(4-methoxyphenyl)-4-(4-methanesulfonylphenyl)-3-phenylpyran-2-one regiosiomer (12o) was a less potent and selective COX-2 inhibitor (COX-2 IC50 = 0.45 muM; SI = 70). A molecular modeling study for 12e indicated that the p-OMe substituent on the C-6 phenyl ring interacts with the COX-2 binding site amino acids Ile(345), Val(349), Leu(359), Leu(531), and Met(535) and that the OMe substituent may be responsible for proper orientation of the C-3 p-SO2Me-phenyl ring within the COX-2 secondary pocket (Gln(192), Arg(513), and Phe(518)). These results show that the COX-2 selectivity and potency of 3,4,6-triphenylpyranone regioisomers can be modulated by appropriate placement of the p-SO2Me pharmacophore on either the C-3 or C-4 phenyl moiety. In addition, electronic properties at the para-position of a C-6 phenyl substituent on the central pyranone ring govern COX-2 inhibitory potency and selectivity by controlling the orientation of the p-SO2Me pharmacophore within the COX-2 secondary pocket.

  The stereoselective E‐iodosulfonylation of internal alkynes for synthesizing highly defined tetrasubstituted olefins using sodium phenyl sulfinate and iodine has been achieved. Most of the alkynes explored are non‐symmetrical and the regioselection is under full control. Arylalkynes with various electron‐withdrawing groups like keto, aldehyde, ester, amide, cyano, sulfone, bromo, chloro and iodo on

  Alkynylboronates can be employed as a practical and versatile precursor for a variety of pi-conjugated organic compounds. In the presence of Cu(I) salt, cross-coupling reactions of acid chlorides with alkynylboronates giving rise to the corresponding conjugated ynones takes place readily in aprotic polar solvents such as DMI under neutral conditions.
