S-adenosyl-L-methionine disulfate p-toluene-sulfonate

The disulfate salt of the stable p-toluene-sulfonate complex of s-adenosyl-L-methionine (SAMe) with chemopreventive activity. SAMe disulfate p-toluene-sulfonate undergoes hydrolytic conversion to its active compound SAMe within cells. Although the mechanism of action is largely unknown, SAMe attenuates experimental liver damage and prevents experimental hepatocarcinogenesis. In addition, SAMe may reduce mitochondrial cytochrome C release, caspase 3 activation, and poly(ADP-ribose) polymerase cleavage, and attenuate okadaic acid-mediated hepatocyte apoptosis in a dose-dependent manner. SAMe is an essential compound in cellular transmethylation reactions and a precursor of polyamine and glutathione synthesis in the liver; SAMe deficiency is associated with chronic liver disease-associated decreases in the activity of methionine adenosyltransferase 1A (MAT1A), the enzyme that catalyzes the production of SAMe as the first step in methionine catabolism.

sabarubicin

A disaccharide analogue of the anthracycline antineoplastic antibiotic doxorubicin. Sabarubicin intercalates into DNA and interacts with topoisomerase II, thereby inhibiting DNA replication and repair and RNA and protein synthesis. This agent also induces apoptosis through a p53-independent mechanism. Sabarubicin is less cardiotoxic than doxorubicin.

sagopilone

A fully synthetic low-molecular-weight epothilone with potential antineoplastic activity. Sagopilone binds to tubulin and induces microtubule polymerization while stabilizing microtubules against depolymerization, which may result in the inhibition of cell division, the induction of G2/M arrest, and apoptosis. The agent is not a substrate for the P-glycoprotein (P-gp) efflux pump and so may exhibit activity in multidrug-resistant (MDR) tumors. The epothilone class of metabolites was originally isolated from the myxobacterium Solangium cellulosum.

Through a mechanism that is reported to be different from other approved AR antagonists, selective androgen receptor modulator MDV3100 inhibits the activity of prostate cancer cell ARs, which may result in a reduction in prostate cancer cell proliferation and, correspondingly, a reduction in the serum prostate specific antigen (PSA) level. AR over-expression in prostate cancer represents a key mechanism associated with prostate cancer hormone resistance.

seliciclib

An orally bioavailable, small-molecule cyclin-dependent kinase (CDK) inhibitor with potential proapoptotic and antineoplastic activities. Seliciclib primarily inhibits CDK2/E, CDK2/A, CDK7 and CDK9 by competing for their ATP binding sites, leading to a disruption of cell cycle progression. In addition, this agent appears to interfere with CDK-mediated phosphorylation of the carboxy-terminal domain of RNA polymerase II, inhibiting RNA polymerase II-dependent transcription, which may result in the down-regulation of antiapoptotic proteins such as induced myeloid leukemia cell differentiation protein Mcl-1. CDKs, serine/threonine kinases that play an important role in cell cycle regulation, are overexpressed in various malignancies. Mcl-1 belongs to the Bcl-2 family of antiapoptotic proteins and is a protein crucial to the survival of a range of tumor cell types.

MEK 1 and 2 are dual-specificity kinases that are essential mediators in the activation of the RAS/RAF/MEK/ERK pathway, are often upregulated in various tumor cell types, and are drivers of diverse cellular activities, including cellular proliferation.

semuloparin

An ultralow-molecular-weight heparin (ULMWH) (Mw: 2000-3000 daltons) consisting of a polydisperse mixture of oligomeric heparin fragments with potential anticoagulant activity. Semuloparin binds to and activates antithrombin III (ATIII), which may result in the inhibition of activated factor Xa and, to a much lesser extent, factor IIa (thrombin) and so the inhibition of fibrin formation. Compared to low-molecular-weight heparins (LMWHs), AVE5026 exhibits an even higher ratio of anti-Factor Xa to anti-Factor IIa activity (>30:1). Compared to unfractionated heparins, the use of LMWHs is associated with lower incidences of major bleeding, osteoporosis and heparin-induced thrombocytopenia. Like LMWHs, this agent may inhibit tumor growth by regulating angiogenesis and apoptosis. AVE5026 is prepared by partial depolymerization of unfractionated porcine mucosal heparin.

senna extract

An extract made from the dried leaflets on the pods of Cassia angustifolia or Cassia acutifolia with cathartic activity. Dimeric glycosides in dried senna extract are converted to the active monoanthrones by bacterial action in the colon. Through direct effects on enterocytes, enteric neurons, and muscle, monoanthrones produce giant migrating colonic contractions in addition to water and electrolyte secretion. As do other stimulant laxatives, monoanthrones may induce a limited low-grade inflammation in the colon through activation of prostaglandin/cyclic AMP and nitric oxide/cyclic GMP pathways and perhaps inhibition of Na+, K+-ATPase.

sheddase inhibitor INCB007839

An orally bioavailable inhibitor of the ADAM (A Disintegrin And Metalloprotease) family of multifunctional membrane-bound proteins with potential antineoplastic activity. Sheddase inhibitor INCB007839 represses the metalloproteinase "sheddase" activities of ADAM10 and ADAM17, which may result in the inhibition of tumor cell proliferation. The metalloproteinase domains of ADAMs cleave cell surface proteins at extracellular sites proximal to the cell membrane, releasing or "shedding" soluble protein etcodomains from the cell surface; the disintegrin domains of these multifunctional proteins interact with various components of the extracellular matrix (ECM). ADAM10 processes particular epithelial growth factor receptor (EGFR) ligands and appears to regulate Notch signaling through the cleavage of Notch and its related ligand delta-like ligand-1 (Dll-1). ADAM17 (also known as Tumor necrosis factor-Converting Enzyme or TACE) is involved in processing tumor necrosis factor (TNF) from its membrane bound precursor to its soluble circulating form and in processing ligands for the epidermal growth factor receptor (EGFR) family.

silatecan AR-67

A synthetic, highly lipophilic derivative of camptothecin, with potential antineoplastic and radiosensitizing activities. Silatecan DB-67 binds to and stabilizes the topoisomerase I-DNA covalent complex, inhibiting the religation of topoisomerase I-mediated single-stranded DNA breaks and producing lethal double-stranded DNA breaks when encountered by the DNA replication machinery; inhibition of DNA replication and apoptosis follow. Camptothecin readily undergoes hydrolysis at physiological pH, changing its conformation from the active lactone structure to an inactive carboxylate form. Modifications on the E ring of camptothecin prevent binding of human serum albumin, which prefers the inactive carboxylate form, thereby enhancing the stability of the active lactone structure and resulting in prolonged agent activity. In addition, this agent may radiosensitize tumor cells.

IAPs are overexpressed by many cancer cell types and suppress apoptosis by binding to and inhibiting active caspases-3, -7 and -9 via their baculoviral lAP repeat (BIR) domains. Smac, the endogenous IAP antagonist, relies on its N-terminal four amino-acid motif for binding to IAPs.

SMAC mimetic LCL161

An orally bioavailable second mitochondrial-derived activator of caspases (SMAC) mimetic and inhibitor of IAP (Inhibitor of Apoptosis Protein) family of proteins, with potential antineoplastic activity. SMAC mimetic LCL161 binds to IAPs, such as X chromosome-linked IAP (XIAP) and cellular IAPs 1 and 2. Since IAPs shield cancer cells from the apoptosis process, this agent may restore and promote the induction of apoptosis through apoptotic signaling pathways in cancer cells.

SMO is a G-protein coupled receptor that lies just downstream of the SHH ligand cell surface receptor Patched-1 in the SHH pathway; in the absence of ligand Patched-1 inhibits SMO and ligand binding to Patched-1 results in increased levels of SMO. The SHH signaling pathway plays an important role in cellular growth, differentiation and repair; constitutive activation of this pathway is associated with uncontrolled cellular proliferation and has been observed in a variety of cancers.

Smoothened antagonist LDE225 topical

A topical formulation of the small-molecule Smoothened (Smo) antagonist LDE225 with potential antineoplastic activity. Upon topical application, smoothened antagonist LDE225 topical selectively binds to the Hedgehog (Hh)-ligand cell surface receptor Smo, which may result in the suppression of the Hh signaling pathway and, so, the inhibition of tumor cells in which this pathway is abnormally activated. The Hh signaling pathway plays an important role in cellular growth, differentiation and repair. Inappropriate activation of Hh pathway signaling and uncontrolled cellular proliferation, as is observed in a variety of cancers, may be associated with mutations in the Hh-ligand cell surface receptor Smo.

Smoothened antagonist LEQ506

An orally bioavailable small-molecule Smoothened (Smo) antagonist with potential antineoplastic activity.

The Hh signaling pathway plays an important role in cellular growth, differentiation and repair. Dysregulated activation of Hh pathway signaling and uncontrolled cellular proliferation, as is observed in a variety of cancers, may be associated with mutations in the Hh-ligand cell surface receptor Smo.

SN-38-loaded polymeric micelles NK012

A formulation consisting of polymeric micelles loaded with the irinotecan metabolite SN-38 with potential antineoplastic activity. SN-38-loaded polymeric micelles NK012 is an SN-38-releasing nanodevice constructed by covalently attaching SN-38 to the block copolymer PEG-PGlu, followed by self-assembly of amphiphilic block copolymers in an aqueous milieu. SN-38 (7-ethyl-10-hydroxy-camptothecin), a biological active metabolite of the prodrug irinotecan (CPT-11), binds to and inhibits topoisomerase I by stabilizing the cleavable complex between topoisomerase I and DNA, resulting in DNA breaks, inhibition of DNA replication, and apoptosis. SN-38 has been reported to exhibit up to 1,000-fold more cytotoxic activity against various cancer cells in vitro than irinotecan. This formulation increases the water-solubility of SN-38 and allows the delivery of higher doses of SN-38 than those achievable with SN-38 alone.

sodium bicarbonate solution

An aqueous oral mouthwash solution containing the monosodium salt of carbonic acid with alkalinizing and antimucositis activities. Upon introduction into the mouth, the sodium bicarbonate dissociates, forming sodium and bicarbonate ions, which buffer excess hydrogen ion and elevates the oral pH. An alkaline oral environment is less prone to colonization with yeast and aciduric bacteria. In addition, this solution may help relieve mucositis and mucositis-induced pain by diluting human saliva, and cleansing and lubricating mucosal tissues of the mouth, tongue and oropharynx.

Sodium carboxymethylcellulose is a non-toxic, non-allergenic, anionic water-soluble polymer derived from cellulose.

sodium citrate

The sodium salt of citrate with alkalinizing activity. Upon absorption, sodium citrate dissociates into sodium cations and citrate anions; organic citrate ions are metabolized to bicarbonate ions, resulting in an increase in the plasma bicarbonate concentration, the buffering of excess hydrogen ion, the raising of blood pH, and potentially the reversal of acidosis. In addition, increases in free sodium load due to sodium citrate administration may increase intravascular blood volume, facilitating the excretion of bicarbonate compounds and an anti-urolithic effect.

sodium dichloroacetate

Upon application, sodium hyaluronate topical hydrogel adheres to injured tissues, hydrates skin, and provides protection from further chemical or mechanical irritation. Hyaluronate, a non-sulfated glucosaminoglycan, is a chief component of the extracellular matrix in connective, epithelial, and neural tissues and contributes significantly to cell proliferation and migration.

sodium metaarsenite

A highly soluble, orally available trivalent arsenic-containing telomerase inhibitor with potential antitumor activity. Although the exact mechanism through which sodium metaarsenite exerts its effect has yet to be fully elucidated, this agent appears to target and bind to telomeric sequences, specifically TTAGGG repeats, leading to a shortening of telomeres, and subsequent induction of apoptosis and inhibition of tumor cell growth. In addition, sodium metaarsenite also leads to the translocation of the catalytic subunit of telomerase into the cytoplasm and inhibition of the activity of telomerase. Telomerase is active in most tumors cells and is responsible for the maintenance of telomere length and plays a key role in cellular proliferation, but is quiescent in normal, healthy cells. The susceptibility to sodium metaarsenite seems to be inversely correlated with initial length of telomeres.

sodium phenylbutyrate

The sodium salt of phenylbutyrate, a derivative of the short-chain fatty acid butyrate, with potential antineoplastic activity. Phenylbutyrate reversibly inhibits class I and II histone deacetylases (HDACs), which may result in a global increase in gene expression, decreased cellular proliferation, increased cell differentiation, and the induction of apoptosis in susceptible tumor cell populations.

sodium picosulfate/magnesium oxide/citric acid oral laxative

An oral laxative formulation containing the stimulant cathartic sodium picosulfate as the primary active ingredient . Picosulfate acts on the enteric nerves in the intestinal wall to increase muscle contractions, thereby stimulating peristaltic action and promoting defecation. Other active ingredients are osmotic agents that increase stool water content.

sodium selenite

An inorganic form of the trace element selenium with potential antineoplastic activity. Selenium, administered in the form of sodium selenite, is reduced to hydrogen selenide (H2Se) in the presence of glutathione (GSH) and subsequently generates superoxide radicals upon reaction with oxygen. This may inhibit the expression and activity of the transcription factor Sp1; in turn Sp1 down-regulates androgen receptor (AR) expression and blocks AR signaling. Eventually, selenium may induce apoptosis in prostate cancer cells and inhibit tumor cell proliferation.

sonepcizumab

A humanized monoclonal antibody directed against sphingosine 1-phosphate (S1P) with potential antiangiogenic and antineoplastic activities. Upon administration, sonepcizumab binds S1P, which may result in the inhibition of tumor angiogenesis. S1P is the extracellular ligand for the G protein-coupled lysophospholipid receptor EDG-1 (endothelial differentiation gene-1).
