[Research progress on animal and cell models of pneumoconiosis].

Pneumoconiosis is an occupational lung disease with the highest incidence in China. There is no effective treatment drug at present. Animal and cell models are the basis for exploring its pathogenesis and developing effective drugs. In this paper, we sort out the methods of animal models of pneumoconiosis and the different cell models induced by dust in recent years, by analyzing and summarizing the advantages and disadvantages, modeling time, pathology and changes in important indicators of different preparation methods of animal models, as well as different cell models induced by the dust to simulate different pathological models and pathological stages, to provide basis for the application and improvement of pneumoconiosis model.

Sinugibberol, a new cytotoxic cembranoid diterpene from the soft coral Sinularia gibberosa.

Bioactivity-guided fractionation of a chloroform extract of the soft coral Simularia gibberosa afforded a new cytotoxic cembranoid diterpene, sinugibberol [1]. The structure of 1 was determined by spectral and X-ray crystallographic analysis.
