The reliability of Quantitative Structure – Activity or Property Relationships for prediction of physico-chemical properties and anticancer activity of flavone and isoflavone derivatives was improved by using the quantitative relationships between structurally similar flavone and isoflavone structures (QSSRs). The targeted-compound method was developed by a training set, which contains only similar compounds structurally to target compound.

The thesis has found a new method to increase the pore size of mesoporous carbon by filling the liquid glass into the pore of the template (silica SBA-15) before impregnating the carbon presource to limit the penetration of carbon sealed the pore system of SBA-15. Stability of mesoporous carbon is increases due to silicon are partially retained in materials. This technique opens the way of synthesis of mesoporous carbon as an adsorbent with a desired pore size and stability.

In this paper, a biologically active substance of Lingzhi mushroom was studied. The optima process seperating (1,3)-B-D-glucan from Ganoderma lucidum has been formed and the molecular weight of the preparation is estimated. The structure of (1,3)- -D-glucan unit and its properties are characterized by using HyperChem 7.02 software.

Oceans provide enormous and diverse space for marine life. Invertebrates are conspicuous inhabitants in certain zones such as the intertidal; many are soft- bodied, relatively immobile and lack obvious physical defenses. These animals frequently have evolved chemical defenses against predators and overgrowth by fouling organisms. Marine animals may accumulate and use a variety of toxins from prey organisms and from symbiotic microorganisms for their own purposes. Thus, toxic animals are particularly abundant in the oceans.
