Chemotherapeutic drugs are composed from different compounds. This review provides information about chemotherapeutic drugs that bind to plasma proteins. Cisplatin (a platinum based complex), 5-fluorouracil and ruthenium based drugs are a few examples. Cisplatin interacts covalently and alters the function of the key plasma protease inhibitor molecule -alpha-2-macroglobulin and induces the conformational changes in the protein molecule, thus inactivating it. 5-fluorouracil is metabolized at a large scale and it is associated with Human Serum Albumin. Ruthenium compounds bind with protein plasma serum-albumin and serum transferrin rendering them toxic to cancer cells. The review also details the use of these drugs based on cancer types and their side effects.
