- A novel chrysin thiazole derivative polarizes macrophages to an M1 phenotype via targeting TLR4
-
Tumor-associated macrophages (TAMs) are an important cause of tumorigenesis and tumor development. M2 macrophages can promote tumor growth while M1 macrophages kill tumor cells, therefore, polarizing macrophages to achieve a functional M1 phenotype could effectively play its anti-tumor role. In the current study, we synthesized a novel chrysin derivative which is termed as ChR-TD. And we found ChR-TD might be a ligand of TLR4 that polarized the TAMs towards M1 phenotype and played its anti-tumor role. Further study indicated that ChR-TD reprogrammed the macrophages into an M1 phenotype via TLR4 activation. Moreover, ChR-TD activated TLR4/NF-κB signaling pathway and promoted the NF-κB/p65 translocated into the nuclear, leading to the activation of NF-κB and proinflammatory cytokines release. In addition, type I interferon signaling was also activated by ChR-TD, leading to the expressions of IFN-α and IFN-β and its targeted genes NOS2, MCP-1 and IP-10 were significantly increased in macrophages. Importantly, these effects were disturbed in TLR4?/? macrophages, which are constructed by using CRISPR/Cas9 system. And the molecule docking simulation further indicated that ChR-TD could bind to TLR4 and might be a ligand of TLR4. Hence, these findings suggested that ChR-TD might be a ligand of TLR4 and can be used as a potential lead compound for tumors treatment.

- The development of improved syntheses of PPARγ-sparing, insulin sensitizing thiazolidinedione-ketones
-
Ketones 2 (MSDC-0160) and 3 (MSDC-0602) had been selected for clinical development, however their initial syntheses were considered suboptimal for application deep into clinical trials. Difficulties ranging from the nature of the starting material, alcohol oxidation problems, epoxide opening regioisomeric issues, and endgame ketone redox problems had been encountered. Direct ketone introduction/maintenance was desired for maximum efficiency and convergence was found to be critically dependent upon the acidity of the nucleophilic species (13, 18) and the use of pre- or post-alkylative oximino-ether/oxime protection (vide infra). Improvements in overall yield for the syntheses of 2 (MSDC-0160) and 3 (MSDC-0602) from 20% (2) and 31% (3) respectively, to 44% (2) and 59% (3) were realized.

- Design and synthesis of novel pyranone-based insulin sensitizers exhibiting in vivo hepatoprotective activity
-
Serious hepatic and cardiovascular complications after treatment with the thiazolidinedione (TZD) class of insulin sensitizers have significantly retarded the advancement of new TZD-based peroxisome proliferator-activated receptor agonists that bind with high affinity and selectivity. The aim of the present study is to design new antihyperglycemic agents that promote insulin sensitivity through partial adipogenesis as well as demonstrate beneficial hepatoprotective activity. The results indicated that among forty screened compounds, three of the novel pyranones at a dose of 10 μM increased the preadipocyte differentiation into adipocytes in 3T3-L1 cell lines. They showed an insulin-sensitizing effect by significantly increasing the glucose uptake and exhibited insulin resistance reversal. These compounds at a dose of 20 mg kg-1 significantly protected against thioacetamide-induced hepatotoxic changes in the serum biochemistry as compared to standard hepatoprotectant silymarin and also ameliorated the histopathological alterations in the liver tissues after acute liver injury in Swiss mice.

- Structure-activity requirements for the antiproliferative effect of troglitazone derivatives mediated by depletion of intracellular calcium
-
Depletion of calcium from the endoplasmic reticulum has shown to affect protein synthesis and cell proliferation. The anticancer effect of troglitazone was reported to be mediated by depletion of intracellular calcium stores resulting in inhibition of translation initiation. The unsaturated form of troglitazone displays similar anticancer properties in vitro. In this letter, we report our findings on the minimum structural requirements for both compounds to retain their calcium release and antiproliferative activities.
