The National Cancer Institute (NCI) is part of the National Institutes of Health (NIH), which is one of 11 agencies that compose the Department of Health and Human Services (HHS). The NCI, established under the National Cancer Institute Act of 1937, is the Federal Government's principal agency for ...
A toxic purine analogue. Inosine dialdehyde inhibits ribonucleotide reductase, resulting in decreased synthesis of DNA, RNA, and proteins, and G2/M-phase cell cycle arrest. This agent also forms stable covalent crosslinks in proteins, thereby inhibiting the activity of enzymes involved in nucleic acid synthesis.
Industry:Pharmaceutical
A traditional Chinese herbal medicine derived from the plant Astragalus membranaceus with potential immunopotentiation activity. Jin Fu Kang may stimulate anti-tumor macrophage and natural killer cell activity and may enhance immune recognition of tumor cells by inhibiting the production of T-helper cell type 2 (Th2) cytokines such as interleukin-4 (IL-4) amd interleukin-10 (IL-10).
Industry:Pharmaceutical
A traditional Chinese medicine (TCM) containing a water soluble Bufo toad skin extract that includes the cardiac glycosides bufalin, cinobufagin and resibufogenin with potential antineoplastic and antiangiogenic activities. Although the exact mechanism of action of this TCM has yet to be fully elucidated, huachansu, which may be administered in an injectable form, may induce cell cycle arrest and apoptosis by suppressing the expression of anti-apoptotic proteins, such as Bcl-2, while inducing the expression of pro-apoptotic proteins, such as BAX.
Industry:Pharmaceutical
A transdermal formulation containing the synthetic phenylpiperidine opioid agonist fentanyl, with analgesic activity. Upon topical administration, fentanyl diffuses from the transdermal patch through the skin, is transported via the systemic circulation, and selectively binds to the mu-receptor in the central nervous system (CNS), mimicking the effects of endogenous opiates. Stimulation of the mu-receptor inhibits adenyl cyclase activity, induces opening of G-protein-coupled inwardly rectifying potassium (GIRK) channels, and blocks the opening of N-type voltage-gated calcium channels, resulting in hyperpolarization and reduced neuronal excitability; in addition, neuronal release of neurotransmitters such as substance P, GABA, dopamine, acetylcholine and noradrenaline may decrease.
Industry:Pharmaceutical
A transdermal matrix patch containing the synthetic opioid buprenorphine with analgesic and sedative activities. Buprenorphine binds to and activates the mu-opioid receptors in the central nervous system (CNS), thereby mimicking the effects of the endogenous opiates. Binding to opioid receptors stimulates exchange of GTP for GDP, inhibits adenylate cyclase, and decreases intracellular cAMP. This inhibits the release of various nociceptive neurotransmitters, such as substance P, gamma-aminobutyric acid (GABA), dopamine, acetylcholine, noradrenaline, vasopressin, and somatostatin. In addition, buprenorphine closes N-type voltage-gated calcium channels and opens calcium-dependent inwardly rectifying potassium channels, resulting in hyperpolarization, reduced neuronal excitability, analgesia and sedation. Buprenorphine is a partial agonist at the mu-opioid receptor and an antagonist at the kappa-opioid receptor in the CNS.
Industry:Pharmaceutical
A transdermal matrix patch formulation containing the synthetic opioid sufentanil with analgesic activity. Sufentanil binds to and activates the mu-opioid receptors in the central nervous system (CNS), thereby mimicking the effects of the endogenous opioids. Binding of sufentanil to opioid receptors stimulates exchange of GTP for GDP, inhibits adenylate cyclase, and decreases intracellular cAMP. This inhibits the release of various nociceptive neurotransmitters, such as substance P, gamma-aminobutyric acid (GABA), dopamine, acetylcholine, noradrenaline, vasopressin, and somatostatin. In addition, sufentanil closes N-type voltage-gated calcium channels and opens calcium-dependent inwardly rectifying potassium channels, which results in hyperpolarization of neuronal membranes and a reduction in neuronal excitability, and, subsequently, analgesia and sedation.
Industry:Pharmaceutical
A transforming growth factor (TGF)-beta2 specific phosphorothioate antisense oligodeoxynucleotide with the sequence 5'-CGGCATGTCTATTTTGTA-3', with potential antineoplastic activity. Trebedersen binds to TGF-beta2 mRNA causing inhibition of protein translation, thereby decreasing TGF-beta2 protein levels; decreasing intratumoral TGF-beta2 levels may result in the inhibition of tumor cell growth and migration, and tumor angiogenesis. TGF-beta2, a cytokine often over-expressed in various malignancies, may play an important role in promoting the growth, progression, and migration of tumor cells.
Industry:Pharmaceutical
A triazene triepoxide with antineoplastic activity. Teroxine alkylates and cross-links DNA, thereby inhibiting DNA replication.
Industry:Pharmaceutical
A triazole with antifungal activity. Ravuconazole inhibits 14a demethylase, an enzyme involved in sterol synthesis, resulting in lysis of the fungal cell wall and fungal cell death.
Industry:Pharmaceutical
A trichothecene mycotoxin and potent teratogen. Anguidine inhibits initiation of protein synthesis, resulting in the death of rapidly proliferating cells. Anguidine also has been shown to both potentiate and protect against the cytotoxic effects of other drugs.
