Structural exploration, synthesis and pharmacological evaluation of novel 5-benzylidenethiazolidine-2,4-dione derivatives as iNOS inhibitors against inflammatory diseases
摘要:
In our previous work, 3I inhibited the LPS-induced iNOS activity and NO production in RAW 264.7 cells and improved joint inflammation and cartilage destruction in inflammatory model. In this study, we synthesized 59 derivatives and bioisosteres on the basis of 3I by Knoevenagel condensation and biologically evaluated for the study of structure-activity relationship (SAR). We found that 7-44 suppressed the iNOS activity (IC50 25.2 mu M) and LPS-induced NO production (IC50 45.6 mu M) in RAW 264.7 cells. As for the SAR study, the dimethoxylphenyl group of 7-44 was potential for a further modification. At a dose of 10 mg/kg, oral administration of 7-44 possessed protective properties in both carrageenan-induced paw edema of male ICR mice and adjuvant-induced arthritis of Lewis female rats. Although the activity of 7-44 was slightly inferior, the PK profiles of 7-44 were superior to those of 3I. (C) 2014 Elsevier Masson SAS. All rights reserved.

The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.
