Valproic acid (VPA; valproate; di-n-propylacetic acid, DPA; 2-propylpentanoic acid, or 2-propylvaleric acid) was first synthesized in 1882, by Burton. FDA approved valproic acid for the treatment of manic episodes associated with bipolar disorder, for the monotherapy and adjunctive therapy of complex partial seizures and simple and complex absence seizures and adjunctive therapy in patients with multiple seizure types that include absence seizures and for the prophylaxis of migraine headaches. The mechanisms of VPA which seem to be of clinical importance in the treatment of epilepsy include increased gamma-aminobutyric acid (GABA)-ergic activity, reduction in excitatory neurotransmission, and modification of monoamines. Recently, it was discovered that the VPA is a class I selective histone deacetylase inhibitor. This activity can be distinguished from its therapeutically exploited antiepileptic activity.

The selenite anion is a selenium oxoanion with the chemical formula SeO2−3. A selenite (Se) is a compound that contains this ion. Sodium selenite is an inorganic form of the trace element selenium with potential antineoplastic activity. It was documented that Se deficiency observed in some countries and/or geographic regions (e.g. Keshan region in China), is associated with an increased morbidity and mortality of neoplastic diseases. To correct this problem a number of organic and inorganic selenium compounds were developed and tested. However, it is now firmly established that only an inorganic sodium selenite with four-valent Se, and not that with six-valent (selenate) cation shows anticancer activity. Selenite can undergo redox reaction, for example with protein's sulfhydryl groups expressed on the surface of tumor cells. In this way selenite prevents non-enzymatic formation of parafibrin that coats tumors cells and hence presents them as 'self' to the innate cellular immune system. Consequently, macrophages of the lymphatic system do not recognize neoplastic cells as 'foreign' bodies and spare them from the immune destruction. Sodium selenite also showed promise as a cost-effective, nontoxic anti-inflammatory agent. Treatment with sodium selenite lowers reactive oxygen species (ROS) production, causes a spontaneous reduction in lymphedema volume, increases the efficacy of physical therapy for lymphedema, and reduces the incidence of erysipelas infections in patients with chronic lymphedema. Limited evidence has been presented though that intakes of selenium greater than the amount needed to allow full expression of selenoproteins may have chemopreventive effects against cancer. Controlled intervention studies are needed to fully evaluate selenium as a cancer chemopreventive agent. The US Food and Drug Administration approved a selenium supplement to animal diets; the most common form is sodium selenite for pet foods.

Iothalamic Acid is an iodine-containing organic anion used as a radiocontrast agent. It is available as sodium iothalamate (Iothalamate sodium) and meglumine iothalamate (Iothalmate meglumine). It can be administered intravenously or intravesically (into the urinary bladder). Iothalamate is indicated to visualize specific regions of the vascular system and blood flow in these areas to help in the diagnosis and evaluation of neoplasms (known or suspected) or vascular diseases (congenital or acquired) that may cause changes in normal vascular anatomy or physiology. Iothalamate meglumine injection is indicated for use in cerebral angiography, peripheral arteriography or venography, arterial digital subtraction angiography1 , and intravenous digital subtraction angiography. Iothalamate meglumine and iothalamate sodium injection is indicated for use in selective coronary arteriography, selective renal arteriography, and in intravenous digital subtraction angiography. othalamate meglumine and iothalamate sodium injection and iothalamate sodium injection are indicated to visualize the aorta and its major branches. However, the injection of iothalamate meglumine and iothalamate sodium is preferred because it generally causes less severe hemodynamic, neurotoxic, and cardiotoxic effects than the individual injection of iothalamate sodium. Radioactive formulation is also available as sodium iothalamate I-125 Injection (GLOFIL-125). It is indicated for evaluation of glomerular filtration in the diagnosis or monitoring of patients with renal disease.

This compound belongs to the class of organic compounds known as aminobenzoic acids. These are benzoic acids containing an amine group attached to the benzene moiety. A commonly used x-ray contrast medium. Used, alone or in combination, for a wide variety of diagnostic imaging methods, including angiography, urography, cholangiography, computed tomography, hysterosalpingography, and retrograde pyelography. It can be used for imaging the gastrointestinal tract in patients allergic to barium. Radiopaque agents are drugs used to help diagnose certain medical problems. They contain iodine, which blocks x-rays. Depending on how the radiopaque agent is given, it localizes or builds up in certain areas of the body. The resulting high level of iodine allows the x-rays to make a "picture" of the area. The areas of the body in which the radiopaque agent localizes will appear white on the x-ray film. This creates the needed distinction, or contrast, between one organ and other tissues.

Edetic acid (EDTA) is a chelating agent. The U.S. Food and Drug Administration (FDA) approved edetic acid chelation therapy as a treatment for lead and heavy metal poisoning. Edetic acid in form of disodium salt was withdrawn from the market due to death resulting from hypocalcemia during chelation.

Leucovorin is a compound similar to folic acid, which is a necessary vitamin. It has been around and in use for many decades. Leucovorin is a medication frequently used in combination with the chemotherapy drugs fluoruracil and methotrexate. Leucovorin is not a chemotherapy drug itself, however it is used in addition to these chemotherapy drugs to enhance anticancer effects (with fluorouracil) or to help prevent or lessen side effects (with methotrexate). Leucovorin is also used by itself to treat certain anemia problems when folic acid deficiency is present.
