Abstract:
A series of novel marine phidianidine derivatives were designed, synthesized, and evaluated for their immunosuppressive activities during our search of potential immunosuppressive agents with high efficacy and low toxicity from marine sources. These compounds were tested for their inhibitory activity on Con A-induced T cell and lipopolysaccharide-induced B cell proliferation. Compounds 14a and 18c, displaying the most promising inhibitory effects and low toxicities, were further found to possess immune-regulatory activities upon cross-linking of T cell receptor (TCR) and B cell receptor (BCR) on purified T and B cells, respectively.

Cell Potential and Free Energy
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...
Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.

Lagging Strand Synthesis
There are several major differences between synthesis of the leading strand and synthesis of the lagging strand. 1) Leading strand synthesis happens in the direction of replication fork opening, whereas lagging strand synthesis happens in the...
