Abstract:
Novel heteroanthracycline antitumor drugs were designed based on structure activity relationship studies and known mechanisms of drug action. Their preparation required the development of a general synthetic approach.<br>After extensive studies, three methodologies were developed for the general synthetic plan. The first method involved photoenolisation of 2,5-dimethoxybenzaldehyde and SO$ sb2$ entrapment of the o-quinodimethane to give 4,7-dimethoxy-1-hydroxy-1,3-dihydrobenzo(2,3-c) thiophene-2,2-dioxide.

Abstract:
Background: Exosomes are extracellular vesicles (EVs) that produced in the endosomal compartment of most eukaryotic cells, and have observed increasing attentions over the past decades. They play important roles in cell- to-cell communications, they can carry varieties of substances, like proteins, nucleic acids and lipids, to the target cells they encounter. These cargos could influence the function of recipient cells. This novel mode of intercellular communication is found to be of critical importance to many cellular activities. However, exosomes are involved in various diseases processes.

Calcium ions have important roles in cellular processes including intracellular signaling, protein folding, enzyme activation and initiation of programmed cell death. Cells maintain low levels of calcium in their cytosol in order to regulate these processes. When activation of calcium-dependent processes is needed, cells can release calcium stored in the endoplasmic reticulum (ER) into the cytosol to initiate the processes. This can also initiate formation of plasma membrane channels that allow entry of additional calcium from the extracellular milieu. The change in calcium levels is referred

Computer-aided drug design is a rapidly growing area of research. The design process can proceed from two angles: either the three-dimensional structure of the biological target is known, or it is unknown. Thus the area of computer-aided drug design can be separated into a number of problems. One problem is determining the structure of a biomolecule from experimental data, as is done in chapter 2 for colominic acid polylactone. These studies determined that there are two helical structures consistent with spectral data A second problem is designing a ligand complementary to the three-dimension
