Screening Search for Biologically Active Substances to Insects in Crude Drug Plants

Medical Uses: Biologically Active Substances

Biologically active substances from the genus Artemisia.

Artemisia species, widespread in nature, are frequently utilized for the treatment of diseases such as malaria, hepatitis, cancer, inflammation, and infections by fungi, bacteria, and viruses. Furthermore, some Artemisia constituents were found to be potential insecticides and allelopathic chemicals. This genus is receiving growing attention presumably due to: (i) the diversified biology and ch...

Search for new compounds and biologically active substances from Chinese marine organisms*

In search of new pharmaceutically valuable substances from marine organisms, we have been engaged in chemical studies on the constituents of corals, sponges and algae collected in the South China Sea. This paper summarizes some of our research results. Terpenes, nitrogen-containing compounds and polyhydroxylated sterols are mainly discussed. The corals, marine sponges and algae are abundant nat...

PASS: prediction of activity spectra for biologically active substances

The concept of the biological activity spectrum was introduced to describe the properties of biologically active substances. The PASS (prediction of activity spectra for substances) software product, which predicts more than 300 pharmacological effects and biochemical mechanisms on the basis of the structural formula of a substance, may be efficiently used to find new targets (mechanisms) for s...

Nanodiamonds as Carriers for Address Delivery of Biologically Active Substances

Surface of detonation nanodiamonds was functionalized for the covalent attachment of immunoglobulin, and simultaneously bovine serum albumin and Rabbit Anti-Mouse Antibody. The nanodiamond-IgG(I125) and RAM-nanodiamond-BSA(I125) complexes are stable in blood serum and the immobilized proteins retain their biological activity. It was shown that the RAM-nanodiamond-BSA(I125) complex is able to bi...
