  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.

  摘要：

  通过将芳氧基乙酰苯胺部分与4'-demethyl-4-deoxypodophyllotoxin（DDPT）的4'-羟基缀合，合成了一组鬼臼毒素（PPT）衍生物（7a-j），并评估了它们的抗癌活性。发现最有效的化合物7d以微摩尔IC 50值低抑制了三种癌细胞系的增殖。此外，已证明7d诱导MGC-803细胞中G2 / M期的细胞周期停滞，并调节细胞周期检查点蛋白如细胞周期蛋白A，细胞周期蛋白B，CDK1，cdc25c和p21的表达。最后，4 mg / kg的7d减少了小鼠HepG2异种移植的重量和体积。我们的发现表明7d可能是一种潜在的抗癌药。

  Treatment of widely available isocyanates with monohalolithium and dihalolithium carbenoids provides a valuable protocol for the one-pot preparation of -halo- and ,-dihaloacetamide derivatives. While monohalolithium carbenoids can be prepared by a smooth lithium-halogen exchange, the preparation of the corresponding dihalo compounds proved to be highly dependent on the base used to realize the deprotonation, with lithium 2,2,6,6-tetramethylpiperidine emerging as optimal. The clear advantages of the procedure are: (a) broad scope of isocyanates that can be employed; (b) preservation of the optical purity when chiral materials are used; (c) divergent access to different haloamides by simply selecting the homologating agents. We also report an application of Charette's imidoyl triflate activation of a secondary amide to the synthesis of an -chloro ketone and N-15 NMR data for selected compounds.
