2. Natural Products as Lead Compounds against Schistosomiasis In recent years, schistosome research has undergone significant progress, but a new chemical entity approved for schistosomiasis treatment is still absent. Indeed, intense efforts are now directed at the discovery of plant extracts with s...

Those bioactive agents have revealed in vitro and in vivo antiviral potentialities against various groups of viruses. Bioactive agents from natural resources have established a great foundation for designing new therapeutic drugs. It is certainly essential to understand the nature, source of origin, and...
Natural products have been the single most productive source of leads for the development of drugs. For example, almost half of the drugs approved between 1994 and 2007 are based on natural products [1-2]. Untapped biological resources, ... SA Pomponi,R Willoughby,ME Kaighn,... 被引量: ...
Dye-sensitized solar cell (DSSC) is a photovoltaic device that can be produced from natural source pigments or natural dyes. The selection of natural dyes for DSSC application is currently under research. The utilization of natural dye materials that are easy to obtain, cost-effective, and non-...
In addition to synthetic and semisynthetic compounds, natural products have received much attention as prolific sources of lead compounds with therapeutic effects on various diseases. In the process of screening the bioactivities of potential candidates,
The nature of the data used also does not allow us to assess different types of migration (long-term vs. short-term mobility, or return migration patterns). Given the fact that census information is the main source of GWPv4, the dataset also presents limitations concerning the potential ...
