Histone deacetylases (HDACs) inhibitors have demonstrated a great clinical achievement in hematological malignancies. However, the efficacy of HDACs inhibitors in treating solid tumors remains limited due to the complicated tumor microenvironment. In this study, we designed and synthesized a class of novel HDACs inhibitors based on the structure of flavones and isoflavones, followed by biological evaluation. To be specific, a lead compound 15a was discovered with strong anti-proliferative effects on a variety of solid tumor cells, especially for breast cancer cells with resistance to SAHA. Studies demonstrated that 15a could significantly inhibit the activity of HDAC 1, 2, 3 (class I) and 6 (class IIB), leading to a dose-dependent accumulation of acetylated histones and α-Tubulin, cell cycle arrest (G1/S phase) and apoptosis in breast cancer cells. Furthermore, the lead compound 15a could also antagonize the activation of STAT3 induced by HDACs inhibition in some breast cancer cells, which further reduced the level of pro-survive proteins in tumor cells and enhanced anti-tumor activity regulated by STAT3 signaling in vivo. Overall, our findings demonstrated that the novel compound 15a might be a HDACs inhibitor candidate, which could be used as promising chemotherapeutic agent for breast cancer.

Chrysin and 7-hydroxy flavone were prepared by Baker-Venkatraman rearrangement followed by esterification at 7th position and replacement of ester with acetamide linking to different heterocyclic moieties synthesized 13a-g and 14a-g series of flavones analogues. These were screened against COX-2 and COX-1 enzymes for inhibition by in vitro assay and COX-2 for in silico docking studies. The compound 14a was found to be most active with IC50 of 3.11 μM concentration, with highest binding energy of -12.4 kcal/mole and 77.2 and 80.5 % inhibition at 3 and 5 h post-carrageenan induced in paw oedema.

A series of novel chrysin derivatives was firstly synthesized and evaluated on their immunosuppressive activity in the search for potential immunosuppressive agents. Among them, compounds 5c displayed the most potent immunosuppressive inhibitory activity with IC50 of 0.78 μM, which was comparable to that of cyclosporin A (IC50 = 0.06 μM). The preliminary mechanism of compound 5c inhibition effects was also detected by flow cytometry (FCM), and the compound exerted immunosuppressive activity via inducing the apoptosis of activated lymph node cells in a dose dependent manner. Furthermore, the estimated LD50 (in mg/kg) in vivo of compound 5c is 738.2, which indicated that compound 5c was low toxic.

A series of furoxan-based nitric oxide-releasing chrysin derivatives were synthesized. Pharmacological assays indicated that all chrysin derivatives exhibited in vitro inhibitory activities against aldose reductase and advanced glycation end-product formation. Some chrysin derivatives were also found to increase the glucose consumption of HepG2 cells. Furthermore, the compounds released a low amount of NO in the presence of l-cysteine (range from 0.20% to 1.89%). These hybrid furoxan-based NO donor chrysin derivatives offer a mutual prodrug design concept for the development of therapeutic or preventive agents for vascular complications due to diabetes.
