The pyrrole moiety as a template for COX-1/COX-2 inhibitors
摘要:
Aroyl- and thiophene-substituted pyrrole derivatives have been synthesized as a new class of COX-1/COX-2 inhibitors. The inhibition of COX-1 was evaluated in a biological system using bovine PMNLs as the enzyme source, whereas LPS-stimulated human monocytes served as the enzyme source for inducible COX-2. The determination of the concentration of arachidonic acid metabolites was performed by HPLC for COX-1 and RIA for COX-2. Variation of the substitution pattern led to a series of active compounds which showed inhibition for COX-1 and COX-2. Structural requirements for the development of COX-1/COX-2 inhibitors are discussed, (C) 2000 Editions scientifiques et medicales Elsevier SAS.

for the design of monoamineoxidase (MAO) inhibitors. This scenario has amplified the momentum for the discovery of heteroaryl based chalcone MAO inhibitors. In the present study, we have synthesized a series of eleven chlorinated thienyl chalcone derivatives substituted with a different functional groups at the para- position on the ring B and investigated for their ability to inhibit human MAO-A and

A series of sulfonamide-containing 1,5-diarylpyrazole derivatives were prepared and evaluated for their ability to block cyclooxygenase-2 (COX-2) in vitro and in vivo. Extensive structure-activity relationship (SAR) work was carried out within this series, and a number of potent and selective inhibitors of COX-2 were identified. Since an early structural lead (1f, SC-236) exhibited an unacceptably long plasma half-life, a number of pyrazole analogs containing potential metabolic sites were evaluated further in vivo in an effort to identify compounds with acceptable pharmacokinetic profiles. This work led to the identification of ii (4-[5-(4-methylphenyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl]benzenesulfonamide, SC-58635, celecoxib), which is currently in phase III clinical trials for the treatment of rheumatoid arthritis and osteoarthritis.

A one step catalytic asymmetric process for the synthesis of an optically active compound of formula la or lb wherein R is selected from C1-7 alkyl, C1-7 haloalkyl, C1-7 alkoxy, C1-7 haloalkoxy, halogen and hydroxy; R3 is H or C1-4 alkyl; R4 is selected from H, C1-7 alkyl, C1-7 haloalkyl, C1-7 alkoxy, COOH, CO-C1-7 alkoxy and an optionally substituted aryl or heterocycle; AR represents C1-7 alkyl, optionally substituted aryl, an optionally substituted heterocycle or AR and R4 may be bridged together forming part of a ring system; X is O or S; m is a number between 0-4; comprising the step of reacting a compound of the formula 2 with a compound of formula 3 in the presence of a catalytic amount of a chiral nitrogen containing organic compound.
