MAGE-A3/HPV 16 peptide vaccine
A multi-epitope "Trojan antigen" ("TA") construct vaccine consisting of human melanoma antigen A3 (MAGE-A3) and human papillomavirus (HPV) 16 peptide epitopes linked by the furin-sensitive linker peptide RVKR (arginine-serine-lysine-arginine) with immunostimulatory and antitumor activities. The TA construct enters the cytoplasm of antigen-presenting cells (APC) and is processed by the endoplasmic reticulum (ER) and the trans-Golgi network (TGN), where the endopeptidase furin releases the epitopes from the RVKR linker peptide and, together with various exopeptidases, generates MHC class I-binding peptides. Expressed on the cell surfaces of APC, these MHC class I-binding peptides stimulate a cytotoxic T lymphocyte (CTL) response against tumor cells that display the same peptide epitopes on their cell surfaces. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

magnesium citrate
The citrate salt of the element magnesium with cathartic activity. The cathartic action of magnesium cations appears to result, in part, from osmotically mediated water retention, which subsequently stimulates peristalsis. In addition, magnesium ions may also stimulate the activity of nitric oxide (NO) synthase and increase the biosynthesis of the phospholipid proinflammatory mediator platelet activating factor (PAF) in the gut. NO may stimulate intestinal secretion via prostglandin- and cyclic GMP-dependent mechanisms while PAF produces significant stimulation of colonic secretion and gastrointestinal motility. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

Milk of magnesium exerts its antacid activity in low doses such that all hydroxide ions that enter the stomach are used to neutralize stomach acid. This agent exerts its laxative effect in higher doses so that hydroxide ions are able to move from the stomach to the intestines where they attract and retain water, thereby increasing intestinal movement (peristalsis) and inducing the urge to defecate. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

magnesium valproate
The magnesium salt of valproic acid (2-propylpentanoic acid) with antiepileptic and potential antineoplastic activities. Magnesium valproate dissociates in the gastrointestinal tract and is absorbed into the circulation as magnesium ions and valproic acid ions; valproic acid may inhibit histone deacetylases, inducing tumor cell differentiation, apoptosis, and growth arrest. In addition, valproic acid exerts an antiepileptic effect, likely by inhibiting enzymes that catabolize the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) catabolism and so increasing concentrations of GABA in the central nervous system (CNS). The presence of the magnesium in this agent may contribute to its anticonvulsant activity and sedative properties. Check for active clinical trials or closed clinical trials using this agent.

However, this agent may potentiate the chemotherapy-induced generation of oxygen free radicals in tumor cells, resulting in the potentiation of chemotherapy-induced cytotoxicity; tumor cells, with higher levels of reactive oxygen species than normal cells, possess a lower threshold for oxygen free radical-mediated cytotoxicity. Mangafodipir is traditionally used as an imaging agent in magnetic resonance imaging (MRI). Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

mannitol
A naturally occurring alcohol found in fruits and vegetables and used as an osmotic diuretic.

Moxifloxacin binds to and inhibits the bacterial enzymes DNA gyrase (topoisomerase II) and topoisomerase IV, resulting in inhibition of DNA replication and repair and cell death in sensitive bacterial species. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

Mozobil
(Other name for: plerixafor)

MPC-6827
A quinazoline derivative with potential dual antineoplastic activities. MPC-6827 binds to and inhibits tubulin polymerization and interrupts microtubule formation, resulting in disruption of mitotic spindle assembly, cell cycle arrest in the G2/M phase, and cell death. This agent is not a substrate for several subtypes of multidrug resistance ABC transporters, such as P-glycoprotein, multidrug resistance-associated protein 1 (MRP1), and breast cancer resistance protein 1 (BCRP1); therefore, it may be useful for treating multidrug resistant (MDR) tumors that express these transporters. In addition, as a vascular disrupting agent (VDA), MPC-6827 appears to disrupt tumor microvasculature specifically, which may result in acute ischemia and massive tumor cell death. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

MSir
(Other name for: morphine sulfate)

MUC-1 antigen
MUC-1 antigen is a mammary-type apomucin, a high molecular weight transmembrane glycoprotein, of which the extracellular domain is formed by a repeating 20 amino acid sequence (in tandem) with a high content of serine and threonine on which are O-linked carbohydrate chains. MUC-1 synthesis and secretion are features of glandular epithelial tissues; MUC-1 is overexpressed in lactating breast and in breast, ovary, lung, and prostate malignancies. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

MUC-1 peptide vaccine
A cancer vaccine comprised of a synthetic peptide derived from the mucin 1 (MUC-1) antigen with potential antineoplastic activity. Upon administration, MUC-1 peptide vaccine may stimulate the host immune system to mount a cytotoxic T lymphocyte (CTL) response against tumor cells positive for the MUC-1 antigen, resulting in decreased tumor growth. Overexpressed by many tumor cell types, MUC-1 antigen, a mammary-type apomucin, is a high-molecular-weight transmembrane glycoprotein. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

MUC1-KLH conjugate vaccine
A peptide vaccine, containing human tumor-associated epithelial mucin (MUC1) conjugated with keyhole limpet hemocyanin (KLH), with potential antineoplastic activity. Vaccination with MUC1-KLH conjugate vaccine may stimulate humoral and cytotoxic T-lymphocyte (CTL) responses against tumor cells expressing the MUC1 antigen. In this vaccine, MUC1 antigen is conjugated with KLH, an immunostimulant and a hapten carrier, to enhance immune recognition. MUC1 antigen, a membrane-bound glycoprotein expressed by most glandular and ductal epithelial cells, is overexpressed in an aberrant or deglycosylated form in various cancers such as those of the breast, prostate, and ovary. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

MUC1-KLH vaccine/QS21
A peptide vaccine containing the human tumor-associated antigen epithelial mucin (MUC1 antigen) conjugated with keyhole limpet hemocyanin (KLH) and combined with the nonspecific immunoadjuvant QS21 with potential antineoplastic activity. MUC1 antigen is linked with KLH, an immunostimulant and a hapten carrier, in order to enhance immune recognition; the co-administration of saponin-derived QS21 potentially amplifies the total immune response to the MUC1 antigen. Administration of MUC1-KLH vaccine/QS21 may result in both the production of antitumor antibodies and the stimulation of a cytotoxic T-lymphocyte (CTL) response against tumor cells expressing the MUC1 antigen. MUC1 antigen, a membrane-bound glycoprotein expressed by most glandular and ductal epithelial cells, is overexpressed as an aberrant or deglycosylated form in various cancers such as breast, prostate and ovarian cancers. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

Mucomyst
(Other name for: acetylcysteine)

multi-epitope melanoma peptide vaccine
A peptide cancer vaccine consisting of a combination of peptides derived form several melanoma epitopes. Vaccination with multi-epitope melanoma peptide vaccine stimulates the host immune system to mount a cytotoxic T lymphocyte (CTL) response against tumor cells expressing the corresponding antigens, resulting in tumor cell lysis. This vaccine may stimulate a broader CTL response compared to single-antigen vaccines. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

MultiHance
(Other name for: gadopentetate dimeglumine)

multikinase inhibitor BAY 73-4506
An orally bioavailable small molecule with potential antiangiogenic and antineoplastic activities. Multikinase inhibitor BAY 73-4506 binds to and inhibits vascular endothelial growth factor receptors (VEGFRs) 2 and 3, and Ret, Kit, PDGFR and Raf kinases, which may result in the inhibition of tumor angiogenesis and tumor cell proliferation. VEGFRs are receptor tyrosine kinases that play important roles in tumor angiogenesis; the receptor tyrosine kinases RET, KIT, and PDGFR, and the serine/threonine-specific Raf kinase are involved in tumor cell signaling. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

MultiStem
(Other name for: allogeneic bone marrow-derived adult stem cells)

multitargeted receptor tyrosine kinase inhibitor ABT-869
An orally bioavailable receptor tyrosine kinase (RTK) inhibitor with potential antineoplastic activity. Multitargeted receptor tyrosine kinase inhibitor ABT-869 inhibits members of the vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) receptor families; it exhibits much less activity against unrelated RTKs, soluble tyrosine kinases, or serine/threonine kinases. This agent does not have a general antiproliferative effect due to its high dose requirement. However, ABT-869 may exhibit potent antiproliferative and apoptotic effects on tumor cells whose proliferation is dependent on mutant kinases, such as fms-related tyrosine kinase receptor-3 (FLT3). Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

multitargeted receptor tyrosine kinase inhibitor MP470
An orally bioavailable synthetic carbothioamide with potential antineoplastic activity. Multitargeted receptor tyrosine kinase inhibitor MP470 binds to mutant forms of the stem cell factor receptor (c-Kit; SCFR), inhibiting clinically relevant mutants of this receptor tyrosine kinase that may be associated with resistance to therapy. In addition, MP470 inhibits activities of other receptor tyrosine kinases, such as c-Met, Ret oncoprotein, and mutant forms of Flt3 and PDGFR alpha, which are frequently dysregulated in variety of tumors. This agent also suppresses the induction of DNA repair protein Rad51, thereby potentiating the activities of DNA damage-inducing agents. Mutant forms of c-Kit are often associated with tumor chemoresistance. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
