tropone/inflammation

The aim of this study was to investigate whether a total of twenty benzo[b]cyclohept[e][1,4]oxazines and their S-analogs, and 2-aminotropone derivatives affect the function of activated macrophages. These compounds inhibited the production of pro-inflammatory substances such as nitric oxide (NO) by

Tropone or tropolone and its derivatives (here together called troponoids) belong to a family of natural products with a seven-membered aromatic ring and various side groups. They are mainly synthesized by plants and fungi, and most troponoids play roles of antibacterial defenses in these organisms.

Twenty-eight naturally occurring Cephalotaxus tropone analogues, including 19 previously undescribed ones, were identified from Cephalotaxus fortunei Hook. var. alpina H. L. Li and C. lanceolata K. M. Feng. The presence of the C20 cephinoids A-E revealed that these tropones were assigned to the
