Abstract:
Preparation of 2',3'-O-carbonyl derivatives of 5'-deoxy-6-azauridine and 6-azauridine using 1,1'-carbonyldiimidazole has been elaborated. 5'-Chloro and 5'-bromo derivatives were prepared by treatment of the 5'-O-mesyl derivative with quaternary ammonium halides, 5'-chloro derivatives also by direct halogenation with thionyl chloride in hexamethylphosphortriamide or with tetrachloromethane, triphenyl phosphine, and dimethylformamide. Derivatives of 5'-bromo-6-azauridine were reduced with tributyltin hydride to 5'-deoxy-6-azauridine compounds. 6-Azauridine 2',3'-carbonate (IVa) and its 5'-deriva

Abstract:
Studies have revealed that the most common kind of cancer in the world is skin cancer. Unrepaired deoxyribonucleic acid (DNA) in skin cells can cause genetic abnormalities or mutations that lead to skin cancer. Early detection is crucial because skin cancer is more treatable in its early stages and tends to gradually spread to other areas of the body. Early detection of signs of skin cancer is essential due to the high mortality, increasing morbidity and expensive medical care of the disease.
