Structures and Biological Activities of Some Toxic Natural Products
Concerning the relation of chemical structures and physiological activities, there are cases in which similar physiological actions are observed among compounds of similar structures, whilst, in contrast, some cases are known in which slight changes of the structure of compounds result in the remarkable alteration or complete loss of their physiological activities. A typical example of the latt...
متن کاملResources and Biological Activities of Natural Polyphenols
The oxidative stress imposed by reactive oxygen species (ROS) plays an important role in many chronic and degenerative diseases. As an important category of phytochemicals, phenolic compounds universally exist in plants, and have been considered to have high antioxidant ability and free radical scavenging capacity, with the mechanism of inhibiting the enzymes responsible for ROS production and ...
متن کاملStereocontrolled total synthesis of natural products with characteristic molecular structures and biological activities.
Total synthetic studies on natural products with promising biological profiles, coupled with their intriguing structural features, are described. The target molecules dealt with in this article are five helianane-type sesquiterpenes (heliannuols A, D and K and heliespirones A and C) and three meroterpenes (breviones A, B and C) with allelopathic activity, as well as four cytotoxic polyketides (...
متن کاملBiological screening of natural products and drug innovation in China.
Natural products have been applied to human healthcare for thousands of years. Drug discovery in ancient times was largely by chance and based on clinical practices. As understanding of therapeutic benefits deepens and demands for natural products increase, previously serendipitous discoveries evolve into active searches for new medicines. Many drugs presently prescribed by physicians are eithe...
