Trilostane reversibly inhibits 3 beta-hydroxysteroid dehydrogenase delta 5-4 isomerase in the adrenal cortex, resulting in the decreased synthesis of mineralocorticoids and glucocorticoids and the decreased conversion of pregnenolone to progesterone. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |

trimethoprim-sulfamethoxazoleA synthetic combination of two antibacterial agents, trimethoprim and sulfamethoxazole. This synergistic combination, also known as co-trimoxazole, inhibits two sequential steps in the bacterial metabolism of folic acid. Trimethoprim is a pyrimidine inhibitor of dihydrofolate reductase; sulfamethoxazole is a sulfamide inhibitor of bacterial dihydrofolate synthetase. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |

trimethylcolchicinic acid
|
trimetrexate glucuronateA lipid soluble methotrexate derivative with potential antineoplastic activity. Trimetrexate glucuronate inhibits the enzyme dihydrofolate reductase, thereby preventing the synthesis of purine nucleotides and thymidylate, with subsequent inhibition of DNA and RNA synthesis. Trimetrexate glucuronate also exhibits antiviral activity. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |

Triostat(Other name for: liothyronine sodium) |
|
triptorelinA synthetic decapeptide agonist analog of luteinizing hormone releasing hormone (LHRH). Possessing greater potency than endogenous LHRH, triptorelin reversibly represses gonadotropin secretion. After chronic, continuous administration, this agent effects sustained decreases in LH and FSH production and testicular and ovarian steroidogenesis. Serum testosterone concentrations may fall to levels typically observed in surgically castrated men. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
|
triptorelin pamoateThe pamoate salt of triptorelin, a synthetic decapeptide agonist analog of luteinizing hormone releasing hormone (LHRH). Possessing greater potency than endogenous LHRH, triptorelin reversibly represses gonadotropin secretion after prolonged administration. After chronic, continuous administration, a sustained decrease in LH, FSH and testicular and ovarian steroidogenesis is observed. The serum testosterone concentration may fall to levels typically seen in surgically castrated men. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |

Trisenox(Other name for: arsenic trioxide) |
|
trivalent influenza vaccineA synthetic vaccine consisting of three inactivated influenza viruses, two different influenza type A strains and one influenza type B strain. Trivalent influenza vaccine is formulated annually, based on influenza strains projected to be prevalent in the upcoming flu season. This agent may be formulated for injection or intranasal administration. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
|
trofosfamideAn orally bioavailable oxazaphosphorine prodrug with antineoplastic activity. Trofosfamide (TFF) is metabolized predominantly to the cyclophosphamide analogue ifosfamide (IFO), which is then metabolized by liver cytochrome P450s to the active isophosphoramide mustard (IPM). IPM alkylates DNA to form DNA-DNA cross-links, which may result in inhibition of DNA, RNA and protein synthesis, and tumor cell apoptosis. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
|
troglitazoneAn orally-active thiazolidinedione with antidiabetic and hepatotoxic properties and potential antineoplastic activity. Troglitazone activates peroxisome proliferator-activated receptor gamma (PPAR-gamma), a ligand-activated transcription factor, thereby inducing cell differentiation and inhibiting cell growth and angiogenesis. This agent also modulates the transcription of insulin-responsive genes, inhibits macrophage and monocyte activation, and stimulates adipocyte differentiation. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
|
tropisetronAn indole derivative with antiemetic activity. As a selective serotonin receptor antagonist, tropisetron competitively blocks the action of serotonin at 5HT3 receptors, resulting in suppression of chemotherapy-and radiotherapy-induced nausea and vomiting. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
|
TroVax(Other name for: recombinant modified vaccinia Ankara-5T4 vaccine) |
|
troxacitabineA dioxolane derivative and a novel L-configuration deoxycytidine analogue with potent antineoplastic activity. When incorporated into growing chain during DNA replication, troxacitabine stops DNA polymerization due to its unnatural L-configuration, in contrast to the normal nucleotides with D-configuration. As a result, this agent terminates DNA synthesis upon incorporated into DNA molecules, and consequently interrupts tumor cell proliferation. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus) |
