The Search for Anticarcinogenic Organoselenium Compounds from Natural Sources

Antimicrobial compounds from natural sources

Infectious diseases are one of the main causes of morbidity and mortality worldwide. Nowadays many infections are often caused by multi-resistant microorganisms resulting in difficult to treat diseases and, consequently, substantial increases in healthcare costs. The relative easy access to the antimicrobials and also the massive employment of these compounds for industrial purposes, including ...

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

Molecular Aspects of the Carcinogenic and Anticarcinogenic Potential of Natural Compounds from Cyanobacteria

Cyanobacteria (blur-green algae) are interest member of a group known as eubacteria, they are photosynthetic prokaryotes, that were originally classified as microalgae and distributed worldwide from polar to equatorial latitudes. They have very specialized cells (heterocyst, Akinetes) that are able to fix nitrogen and serve at high temperature or drought. Synthesis of toxin by many cyanobacteri...

[Novel reactions using organoselenium compounds].

Organoselenium compounds are important tools in the field of synthetic chemistry because their specific reactivities have been used as the key reactions in the synthesis of various organic compounds. Nucleophilic organoselenium reagents are frequently utilized to introduce a selenium atom into organic molecules. However, there is no method available for the direct transformation of a hydroxy gr...
