Intramolecular Diels-Alder reaction of a series of pyrazines bearing a 5-membered-ω-alkene side chain in refluxing trifluoroacetic acid led to the formation of bridged tricyclic compounds. These cycloadducts underwent Retro Diels-Alder reaction in refluxing nitrobenzene to give original pyrazines.

Rosiglitazone has shown promising anti-inflammation effect. To develop preferable anti-inflammatory agents, twenty-two rosiglitazone analogs were synthesized and their anti-inflammatory activity was evaluated. Among these compounds, 6i and 6k displayed excellent inhibitory activities on the production of inflammatory mediators, including nitric oxide (NO), tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6). Furthermore, 6i and 6k showed suppression effects on the nuclear factor-kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) pathways, and this suppression effects could be partially reversed by GW9662, which is a peroxisome proliferator-activated receptor γ (PPARγ) antagonist. Additionally, our docking results exhibited the well combination of 6i and 6k to PPARγ. So the anti-inflammation activity of 6i and 6k was due at least in part, to their interaction with PPARγ.

A series of novel oxazolidinone compounds with a substituted ligustrazine C-ring unit and different substituted groups at the C-5 side chain were designed and synthesized using linezolid as a lead and based on a scaffold hopping strategy. Their antibacterial and anti-inflammatory activities were evaluated. The results of in vitro antibacterial assays showed that all fourteen target compounds displayed potent activity against Gram-positive pathogens, particularly 8b, 13b, 14a, 14b, 15a, and 15b. Moreover, 14a and 14b exhibited significant inhibitory activities on the production of inflammatory mediators, including nitric oxide, interleukin-6, and tumor necrosis factor-alpha. Thus, these derivatives could serve as valuable candidates to develop anti-infective agents for the treatment of chronic wounds.
