Cytarabine

Cytarabine is a chemotherapy agent used mainly in the treatment of cancers of white blood cells such as acute myeloid leukemia (AML) and non-Hodgkin lymphoma.It is called cytosine arabinoside because it combines a cytosine base with an arabinose sugar. Cytosine normally combines with a different sugar, deoxyribose, to form deoxycytidine, a component of DNA. Cytarabine is used to treat different forms of leukemia, including acute and chronic myelogenous (AML and CML) and acute lymphocytic leukemia (ALL). It is also used to treat lymphoma, meningeal leukemia and lymphoma (cancers found in the lining of the brain and spinal cord).It kills cancer cells by interfering with DNA synthesis.Cytarabine is also used in the study of the nervous system to control the proliferation of glial cells in cultures, the amount of glial cells having an important impact on neurons.

Cytidine

Cytidine is a nucleoside molecule that is formed when cytosine is attached to a ribose ring (also known as a ribofuranose) via a β-N1-glycosidic bond. Cytidine is a component of RNA.If cytosine is attached to a deoxyribose ring, it is known as a deoxycytidine.Dietary sources of cytidine include foods with high RNA (ribonucleic acid) contents such as organ meats, Brewer's yeast, as well as pyrimide-rich foods such as beer. During digestion, RNA-rich foods are broken-down into ribosyl pyrimidines (cytidine and uridine), which are absorbed intactIn humans, dietary cytidine is converted into uridine,which is probably the compound behind cytidine's metabolic effects.

D-Mannitol

D-Mannitol is a organic compound. This polyol is used as an osmotic diuretic agent and a weak renal vasodilator. It was originally isolated from the secretions of the flowering ash, called manna after their resemblance to the Biblical food. In plants, it is used to induce osmotic stress. It is used clinically in osmotherapy to reduce acutely raised intracranial pressure until more definitive treatment can be applied. It is also used to treat patients with oliguric renal failure. It can also be used as a facilitating agent for the transportation of pharmaceuticals directly into the brain. It is commonly used in the circuit prime of a heart lung machine during cardiopulmonary bypass. It is also the first drug of choice for the treatment of acute glaucoma in veterinary medicine. It does not stimulate an increase in blood glucose, and is therefore used as a sweetener for people with diabetes, and in chewing gums.
