ublituximab
A chimeric recombinant IgG1 monoclonal antibody directed against human CD20 with potential antineoplastic activity. Ublituximab specifically binds to the B cell-specific cell surface antigen CD20, thereby potentially inducing a B cell-directed complement dependent cytotoxicity (CDC) and antibody-dependent cell-mediated cytotoxicity (ADCC) against CD20-expressing B cells, leading to B cell apoptosis. CD20 is a non-glycosylated cell surface phosphoprotein that is exclusively expressed on B cells during most stages of B cell development and is often overexpressed in B-cell malignancies. Ublituximab has a specific glycosylation profile, with a low fucose content, that may enhance its ADCC response against malignant B cells.

udenafil
A benzenesulfonamide derivative with vasodilatory activity. Udenafil selectively inhibits phosphodiesterase type 5 (PDE5), thus inhibiting the degradation of cyclic guanosine monophosphate (cGMP) found in the smooth muscle of the corpus cavernosa and corpus spongiosum of the penis; inhibition of cGMP degradation results in prolonged muscle relaxation, vasodilation, and blood engorgement of the corpus cavernosa, and, so, prolonged penile erection. This agent does not significantly inhibit the PDE11 isozyme; PDE11 inhibition may be associated with significant myalgia. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
ulimorelin hydrochloride
The hydrochloride salt form of ulimorelin, a macrocyclic ghrelin peptidomimetic, with potential gastrointestinal (GI) prokinetic activity. Upon intravenous administration, ulimorelin binds to the ghrelin receptor in the GI tract and may stimulate GI motility. Ghrelin is a natural ligand for growth hormone secretagogue receptors and is normally localized in the proximal GI tract. The ghrelin receptor signaling pathway mediates multiple GI functions, including motility and gastric emptying. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
ulinastatin
A multivalent Kunitz-type serine protease inhibitor derived from human urine, with potential protective, anti-fibrinolytic and anticoagulant activities. Upon administration, ulinastatin (or urinary trypsinogen inhibitor) inhibits the activities of a variety of enzymes, including trypsin, chymotrypsin, thrombin, kallikrein, plasmin, elastase, cathepsin, lipase, hyaluronidase, factors IXa, Xa, XIa, and XlIa, and polymorphonuclear leukocyte elastase. In addition, ulinastatin inhibits the excessive release of proinflammatory mediators, such as tumor necrosis factor-alpha, interleukin-6 and -8, and chemokines. Altogether, this agent may improve the microcirculation, perfusion and function of tissues and may protect organ injury. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
ulipristal acetate
An orally bioavailable, acetate ester of ulipristal, a selective progesterone receptor modulator with anti-progesterone activity. Ulipristal binds to the progesterone receptor (PR), thereby inhibiting PR-mediated gene expression, and interfering with progesterone activity in the reproductive system. As a result, this agent may suppress the growth of uterine leiomyomatosis. Furthermore, by inhibiting or delaying ovulation and effecting endometrial tissue, ulipristal can be used as an emergency contraception. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
Ultandren

ULvWF multimer-targeting agent ARC1779
An optimized, second-generation, PEGylated aptamer with antithrombotic property. ULvWF multimer-targeting agent ARC1779 blocks the binding of von Willebrand factor (vWF), via the A1 domain, and ultra-large vWF multimers to platelets, as well as interfering with the binding of platelet receptor glycoprotein Ib, thus reducing platelet adhesion, aggregation and thrombus growth in arterial beds. Unlike other antiplatelet agents, this aptamer can be readily reversed by binding to a complementary sequence of oligonucleotides, and may therefore offer potential therapeutic benefit in surgery. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
umbilical cord blood-derived mesenchymal stem cells
Multipotent stem cells of mesenchymal origin isolated from umbilical cord blood. Umbilical cord blood-derived mesenchymal stem cells can differentiate into a variety of cell types including fibroblasts, osteoblasts, chondrocytes, myocytes, adipocytes, and endothelial cells. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
Unasyn
(Other name for: ampicillin sodium/sulbactam sodium) |
uniformly-labeled [U-13C] glucose
A non-radioactive, naturally occurring carbon 13 (13C) glucose isotopomer in which all six carbons are 13C, with potential imaging application. Upon administration of uniformly-labeled [U-13C] glucose, the glucose is taken up and metabolized by tumors and the 13C-containing metabolites can be imaged by 13C nuclear magnetic resonance (NMR) spectroscopy. Since tumor cells take up and metabolize glucose in higher amounts and through different pathways than normal cells, this agent may help assess the metabolic phenotype of the tumor. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
Uniphyl
(Other name for: theophylline) |
uracil
One of the 5 major bases (with adenine, guanine, cytosine, and thymine) which are a component of nucleic acids. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
uracil ointment
A 0.1% topical formulation of uracil used to potentially lower the incidence of hand-foot syndrome (HFS) (or palmar-plantar erythrodysesthesia) during 5-fluorouracil (5-FU) or 5-FU prodrug capecitabine chemotherapy. Upon local administration of uracil ointment to the skin, uracil competes with capecitabine or 5-FU as substrates for the activating enzyme thymidine phosphorylase and the metabolizing enzyme dihydropyrimidine dehydrogenase. This may prevent the production of 5-FU as well as the breakdown of 5-FU into the toxic metabolites locally. As the 5-FU metabolites are responsible for the presentation of HFS, inhibiting their formation may prevent this adverse effect. By applying a high concentration of uracil locally, the skin toxicities of 5-FU may be countered while preserving the systemic anti-cancer activity of the 5FU. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
urelumab
A humanized agonistic monoclonal antibody targeting the CD137 receptor with potential immunostimulatory and antineoplastic activities. Urelumab specifically binds to and activates CD137-expressing immune cells, stimulating an immune response, in particular a cytotoxic T cell response, against tumor cells. CD137 is a member of the tumor necrosis factor (TNF)/nerve growth factor (NGF) family of receptors and is expressed by activated T- and B-lymphocytes and monocytes; its ligand has been found to play an important role in the regulation of immune responses. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
uridine
A nucleoside consisting of uracil and D-ribose and a component of RNA. Uridine has been studied as a rescue agent to reduce the toxicities associated with 5-fluorouracil (5-FU), thereby allowing the administration of higher doses of 5-FU in chemotherapy regimens. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
