Bendamustine, brand name Treanda, is a chemotherapeutic agent that displays a unique pattern of cytotoxicity compared with conventional alkylating agents. Treanda is indicated for the treatment of patients with chronic lymphocytic leukemia (CLL), in addition Trenda in phase III of clinical trial for the treatment patients with indolent B-cell non-Hodgkin lymphoma (NHL) that has progressed during or within six months of treatment with rituximab or a rituximab-containing regimen. Bendamustine is a bifunctional mechlorethamine derivative. Mechlorethamine and its derivatives dissociate into electrophilic alkyl groups. These groups form covalent bonds with electron-rich nucleophilic moieties. The bifunctional covalent linkage can lead to cell death via several pathways. The exact mechanism of action of bendamustine remains unknown. Molecular analyses have revealed that bendamustine differs from other alkylating agents in its mechanism of action. Differences have been observed about its effects on DNA repair and cell cycle progression. Moreover, bendamustine can induce cell death through both apoptotic and nonapoptotic pathways, thereby retaining activity even in cells without a functional apoptotic pathway. Bendamustine possesses the typical adverse reactions for the nitrogen mustards, and include nausea, fatigue, vomiting, diarrhea, fever, constipation, loss of appetite, cough, headache, unintentional weight loss.
Status:
First approved in 1996

Cidofovir is an antiviral nucleotide analogue with significant activity against cytomegalovirus (CMV) and other herpesviruses. Cidofovir suppresses cytomegalovirus (CMV) replication by selective inhibition of viral DNA synthesis. Biochemical data support selective inhibition of CMV DNA polymerase by cidofovir diphosphate, the active intracellular metabolite of cidofovir. Incorporation of cidofovir into the growing viral DNA chain results in reductions in the rate of viral DNA synthesis. Cidofovir is indicated for the treatment of CMV retinitis in patients with acquired immunodeficiency syndrome.
Status:
First approved in 1987

Class (Stereo):
CHEMICAL (RACEMIC)

Targets:


Ifosfamide (IF) is a widely used antitumor prodrug. It is in the oxazaphosphorine class of alkylating agents, and it is effective against solid tumors. Ifosfamide mechanism of crosslinking DNA plays a major role in preventing cancer cells from proliferating. Ifosfamide is approved by FDA for the treatment of germ cell testicular cancer.

Melphalan, also known as L-phenylalanine mustard, phenylalanine mustard, L-PAM, or L-sarcolysin, is a phenylalanine derivative of nitrogen mustard. Melphalan is a bifunctional alkylating agent which produces a number of DNA adducts with the DNA interstrand crosslink (ICL) considered to be the critical cytotoxic lesion. Melphalan is used to treat different cancers including myeloma, melanoma and ovarian cancer.

Tegafur (INN, BAN, USAN) is a chemotherapeutic fluorouracil prodrug used in the treatment of cancers. It is a component of the combination drugs tegafur/uracil and tegafur/gimeracil/oteracil. UFT is an anticancer medication composed of a fixed molar ration (1:4) of tegafur and uracil. This drug is commonly used in the treatment of head and neck cancer, gastric cancer, colorectal cancer, hepatic cancer, gallbladder cancer, bile-duct cancer, pancreatic cancer, lung cancer, breast cancer, bladder cancer, prostatic cancer, or uterine cervical cancer. In the body, tegafur is converted into 5-fluorouracil (5-FU), the active antineoplastic metabolite. The mechanism of cytotoxicity of 5-FU is thought to be derived from the fact that 5-fluoro-deoxyuridine-monophosphate (FdUMP), the active metabolite of 5-FU, competes with deoxyuridine-monophosphate (dUMP), thereby inhibiting thymidylate synthase and subsequently DNA synthesis. Another active metabolite of 5-FU, 5-fluorouridine-triphosphate (FUTP) is integrated into cellular RNA, inhibiting RNA function. Uracil, when combined with tegafur, enhances the antitumor activity of 5-FU due to higher 5-FU concentrations in the tumor tissue versus normal surrounding tissue compared with tegafur alone. Uracil inhibits degradation of the released 5-FU. The combination of these two drugs enhances the antitumor activity of Tegafur.
Cyclophosphamide (the generic name for Cytoxan, Neosar, Revimmune), also known as cytophosphane, is a nitrogen mustard alkylating agent, from the oxazophorines group. It is used to treat various types of cancer and some autoimmune disorders. It is a "prodrug"; it is converted in the liver to active forms that have chemotherapeutic activity

Mechlorethamine also known as mustine, brand name MUSTARGEN administered intravenously is the prototype anticancer chemotherapeutic drug, is indicated for the palliative treatment of Hodgkin's disease (Stages III and IV), lymphosarcoma, chronic myelocytic or chronic lymphocytic leukemia, polycythemia vera, mycosis fungoides, and bronchogenic carcinoma. In 2013 was approved orphan drug Valchlor (mechlorethamine) gel for the topical treatment of stage IA and IB mycosis fungoides-type cutaneous T-cell lymphoma (CTCL) in patients who have received prior skin-directed therapy. Mechlorethamine belongs to the group of nitrogen mustard alkylating agents. Alkylating agents work by three different mechanisms: attachment of alkyl groups to DNA bases, resulting in the DNA being fragmented by repair enzymes in their attempts to replace the alkylated bases, 2) DNA damage via the formation of cross-links (bonds between atoms in the DNA) which prevents DNA from being separated for synthesis or transcription, and 3) the induction of mispairing of the nucleotides leading to mutations all of which achieve the same end result - disruption of DNA function and cell death.
