macimorelin

An orally available synthetic mimetic of the growth hormone (GH) secretagogue ghrelin with potential anti-cachexia activity. Upon oral administration, macimorelin mimics endogenous ghrelin by stimulating appetite and binds to the growth hormone secretagogue receptor GHSR in the central nervous system, thereby mimicking the GH-releasing effects of ghrelin from the pituitary gland. Stimulation of GH secretion increases insulin-like growth factor-I (IGF-I) levels which may further stimulate protein synthesis. In addition, ghrelin reduces the production of pro-inflammatory cytokines, which may play a direct role in cancer-related loss of appetite. Check for active clinical trials using this agent.

mercaptopurine tablet

The anhydrous form of mercaptopurine, a thiopurine-derivative antimetabolite with antineoplastic and immunosuppressive activities.

metformide hydrochloride/pioglitazone hydrochloride extended-release tablet

An extended-release (ER) tablet composed of the hydrochloride salt form of the biguanide metformin and the hydrochloride salt form of the thiazolidinedione pioglitazone, with antihyperglycemic activity. Upon oral administration and although the exact mechanism of action has yet to be fully elucidated, metformin inhibits complex I (NADPH:ubiquinone oxidoreductase) of the mitochondrial respiratory chain and increases the cellular AMP to ATP ratio leading to activation of AMP-activated protein kinase (AMPK).

Upon administration of the solution into the buccal cavity, midazolam exerts its effect by binding to the benzodiazepine receptor at the gamma-aminobutyric acid (GABA) receptor-chloride ionophore complex in the central nervous system (CNS). This leads to an increase in the permeability of chloride channels, membrane hyperpolarization and enhances the inhibitory effect of GABA in the CNS. Midazolam may also interfere with the reuptake of GABA, thereby causing accumulation of GABA in the synaptic cleft. The oromucosal formulation facilitates administration to patients that are unable to swallow. The ethanol in this formulation improves the buccal absorption of midazolam.

midostaurin

A synthetic indolocarbazole multikinase inhibitor with potential antiangiogenic and antineoplastic activities. Midostaurin inhibits protein kinase C alpha (PKCalpha), vascular endothelial growth factor receptor 2 (VEGFR2), c-kit, platelet-derived growth factor receptor (PDGFR) and FMS-like tyrosine kinase 3 (FLT3) tyrosine kinases, which may result in disruption of the cell cycle, inhibition of proliferation, apoptosis, and inhibition of angiogenesis in susceptible tumors.

mifamurtide

A liposomal formulation containing a muramyl dipeptide (MDP) analogue with potential immunomodulatory and antineoplastic activities.. Muramyl tripeptide phosphatidylethanolamine (MTP-PE), a derivative of the mycobacterial cell wall component MDP, activates both monocytes and macrophages. Activated macrophages secrete cytokines and induce the recruitment and activation of other immune cells, which may result in indirect tumoricidal effects. Liposomal encapsulation of MTP-PE prolongs its half-life and enhances tissue targeting. Check for active clinical trials using this agent. (NCI Thesaurus)

Mifeprex

(Other name for: mifepristone)

mifepristone

A derivative of the synthetic progestin norethindrone with antiprogesterone activity. Mifepristone competitively binds to the progesterone receptor, resulting in inhibition of the effects of endogenous or exogenous progesterone. This agent also exhibits antiglucocorticoid and weak antiandrogenic activities. Check for active clinical trials using this agent. (NCI Thesaurus)

miglitol

A desoxynojirimycin derivative and inhibitor of alpha-glucosidase with antihyperglycemic activity. Miglitol binds to and inhibits alpha-glucosidase, an enteric enzyme found in the brush border of the small intestines that hydrolyzes oligosaccharides and disaccharides into glucose and other monosaccharides. This prevents the breakdown of larger carbohydrates into glucose and decreases the rise in postprandial blood glucose levels. Compared to acarbose, miglitol is systemically absorbed.

MiHA-loaded PD-L1/L2-silenced dendritic cell vaccine

A dendritic cell (DC)-based vaccine composed of program death ligands 1 and 2 (PDL1/L2)-silenced DCs and loaded with the recipient’s minor histocompatibility antigens (MiHA), with potential use for graft-versus-tumor (GVT) induction following allogeneic stem cell transplantation (allo-SCT). Donor DCs are electroporated ex vivo with MiHA mRNA and small interfering RNAs (siRNAs) designed to silence the expression of PD L1/L2. After allo-SCT and upon intravenous administration of the MiHA-loaded PD-L1/L2-silenced DC vaccine, the DCs induce the expansion and activation of MiHA-specific CD8-positive T-cells. These tumor antigen-reactive T-cells exert their GVT effect by killing MiHA-positive tumor cells. PD-L1/L2, co-inhibitory ligands expressed on DCs, play key roles in preventing MiHA-specific CD8-positive T-cell expansion; silencing enhances MiHA-specific CD8-positive T-cell expansion and activity and improves the GVT effect. The MiHA are human leukocyte antigen (HLA)-bound peptides and are exclusively expressed by the recipient’s hematopoietic tumor cells. Check for active clinical trials using this agent.

milatuzumab

A humanized monoclonal antibody directed against human CD74 with potential antineoplastic activity. Milatuzumab specifically binds to CD74 on CD74-positive cells. Although the exact mechanism through which this agent induces apoptosis is unknown, it may involve antibody-dependent cellular cytotoxicity (ADCC) or complement-mediated cytotoxicity (CMC). Alternatively, as CD74 is the cellular receptor for the cytokine migration-inhibitory factor (MIF), the cytotoxicity of this agent may be related to inhibition of CD74 activation by MIF. CD74, an integral membrane protein that functions as an MHC class II chaperone, may also be an accessory-signaling molecule; activation of CD74 may initiate cell survival mechanisms involving induction of a signaling cascade resulting in NFkB activation, entry of stimulated cells into the S phase of the cell cycle, elevation of DNA synthesis, cell division, and augmented expression of Bcl-xL.

milatuzumab-doxorubicin antibody-drug conjugate

An immunoconjugate consisting of milatuzumab, a humanized monoclonal antibody against CD74, conjugated to the anthracycline antibiotic doxorubicin with potential antineoplastic activity. The milatuzumab moiety of this antibody-drug conjugate (ADC) selectively binds to CD74 on tumor cell surfaces; upon internalization, the doxorubicin moiety is released, where it intercalates between base pairs in the DNA helix and inhibits topoisomerase II, thereby preventing DNA replication and increasing double-strand breakage. As a result, this agent may inhibit the proliferation of cancer cells that overexpress CD74. CD74, an integral membrane protein and tumor associated antigen (TAA), is overexpressed in certain cancer cells and promotes survival in rapidly proliferating tumor cells. Check for active clinical trials using this agent. (NCI Thesaurus)

milciclib maleate

An orally bioavailable inhibitor of cyclin-dependent kinases (CDKs) and thropomyosin receptor kinase A (TRKA), with potential antineoplastic activity. Milciclib maleate potently inhibits cyclin-dependent kinase 2 (CDK2) and exhibits activity against other CDKs including CDK1 and CDK4, in addition to TRKA. Inhibition of these kinases may result in cell cycle arrest and apoptosis of tumor cells that express these kinases. CDKs are serine/threonine kinases involved in regulation of the cell cycle and may be overexpressed in some cancer cell types. The neurotrophin receptor TRKA is mutated in a variety of cancer cell types. Check for active clinical trials using this agent. (NCI Thesaurus)
