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 ...
An iodine I-123 conjugate of metomidate (MTO) with potential application in adrenal imaging. Metomidate is a potent and selective inhibitor of the cytochrome P-450 enzymes, especially CYP11B1 (11 beta-hydroxylase) and CYP11B2 (aldosterone synthase). Because both CYP11B1 and CYP11B2 are expressed exclusively in the adrenal cortex, I-123 iodometomidate can be used as a radiotracer for adrenal scintigraphy.
Industry:Pharmaceutical
An isolate comprised of the sodium or calcium salt of the glycoprotein casein, the primary protein found in milk and other dairy products, with anti-catabolic activity.

An isothiocyanate found in cruciferous vegetables with chemopreventive and potential antitumor activities. Although the mechanism of action is unclear, phenethyl Isothiocyanate (PEITC) was shown to induce apoptosis in tumor cells, possibly mediated through its metabolic intermediates, reactive oxygen species (ROS). PEITC also is able to activate ERK and JNK signal transduction, which in turn induces expression of stress-responsive genes. Specifically, this agent has been shown to reactivate gene expression of a detoxification enzyme, glutathione S-transferase that is silenced in prostate carcinoma.

An isotonic solution containing macrogol 3350 and electrolytes with laxative activity. Macrogol 3350-based oral osmotic laxative promotes the retention of water in the bowel, thereby increasing the water content of stool, which results in increased gastrointestinal motility and stool transit time and evacuation of colonic contents. Macrogol 3350 is also known as polyethylene glycol (PEG) 3350.
Industry:Pharmaceutical
An L-glutamine diazo analogue amino acid antibiotic isolated from a species of the bacterial genus Streptomyces with potential antineoplastic activity. Diazooxonorleucine inhibits several glutamine-dependent biosynthetic pathways involved in the the syntheses of D-glucosamine phosphate, purines and pyrimidines. This agent inhibits phosphate-activated glutaminase, a key enzyme for the synthesis of releasable glutamine, depleting cells of this essential amino acid and reducing their capacity to proliferate.
Industry:Pharmaceutical
An L-leucine derivative of melphalan with antineoplastic activity. Asaley alkylates and crosslinks DNA, resulting in disruption of DNA synthesis.
Industry:Pharmaceutical
An MDM2 (human homolog of double minutes-2; HDM2) antagonist with potential antineoplastic activity. RO5045337 binds to MDM2, thereby preventing the binding of the MDM2 protein to the transcriptional activation domain of the tumor suppressor protein p53. By preventing this MDM2-p53 interaction, the proteosome-mediated enzymatic degradation of p53 is inhibited and the transcriptional activity of p53 is restored, which may result in the restoration of p53 signaling and thus the p53-mediated induction of tumor cell apoptosis. MDM2, a zinc finger protein, is a negative regulator of the p53 pathway; often overexpressed in cancer cells, it has been implicated in cancer cell proliferation and survival.
Industry:Pharmaceutical
An micronutrient-fortified fermented dairy product with potential positive immunomodulatory activity. Micronutrient-fortified probiotic yogurt contains various micronutrients in addition to beneficial microorganisms, such as strains of Lactobacillus. Probiotic Lactobacillus strains have been shown to protect against gastrointestinal and urogenital infections, to moderate diarrheal episodes, and to increase CD4 T-lymphocyte counts. In immunocompromised subjects, micronutrient supplementation may also increase CD4 T-lymphocyte counts.
Industry:Pharmaceutical
An octapeptide (amino acids 136-143) derived from the proteolytic enzyme urokinase plasminogen activator (uPA), with potential antineoplastic activity. A6 is derived from the nonreceptor-binding domain and connecting region of urokinase. Administration of A6 inhibits the interaction of uPA with its receptor uPAR, and may inhibit endothelial cell motility and tumor cell invasion. UPA and uPAR promote extracellular matrix degradation and growth factor activation and correlate positively with angiogenesis, cancer cell invasion and metastasis.
Industry:Pharmaceutical
An ointment formulation of the hydrochloride salt of an ornithine decarboxylase (ODC) inhibitor with hair-growth inhibitory and potential chemopreventive activities. When administered topically, eflornithine irreversibly inhibits skin ODC activity, thereby inhibiting the synthesis of polyamines; inhibition of polyamine synthesis may result in diminished hair growth and epidermal cell turnover.
