Miller RA, Strong R, Harrison DE, Rosenthal NA


Studied compounds:

    17-a-estradiol: an isomer of 17-b-estradiol that has reduced affinity for the estrogen nuclear receptor; 17-a-estradiol was tested to determine if it would recapitulate the protective effects of 17-b-estradiol and increase lifespan. [Wikipedia article]

    17-dimethylaminoethylamino-17-demethoxygeldanamycin hydrochloride: inhibits heat shock protein 90 (HSP90).

    2-(2-Hydroxyphenyl)benzoxazole: a compound which acts as a multi-site proton acceptor as well as a proton donor, in addition to forming a strong intramolecular hydrogen bond.

    4-OH-a-phenyl-N-tert-butyl nitrone: is the 4-hydroxy derivative and principal metabolite of a-phenyl-N-tert-butyl nitrone (PBN), a commonly used free radical spin trap; PBN has reported pharmacologic activities in stroke and cancer.

    Acarbose: an anti-diabetes drug that inhibits α-glucosidase, slowing carbohydrate breakdown. It was anticipated that it might act as a caloric restriction mimetic. [Wikipedia article]

    Aspirin: a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain, fever, or inflammation. [Wikipedia article]

    b-guanidinopropionic acid: lowers both blood glucose and blood insulin.

    Caffeic acid phenethyl ester: a compound reported to possess anti-oxidant, anti-inflammatory, and immunomodulatory capabilities, as well as specific toxicity to transformed and tumor cells. [Wikipedia article]

    Curcumin: is the principal curcuminoid of turmeric, sold as an herbal supplement. [Wikipedia article]

    Enalapril: a drug reported to improve hypertension, obesity, diabetes and congestive heart failure in aged humans and rodent models. [Wikipedia article]

    Fish oil: a source of omega-3 fatty acids, which have anti-inflammatory properties and are thought to be protective for cardiovascular disease in some human studies. [Wikipedia article]

    Glycine: an amino acid; dietary glycine can block methionine toxicity; excess glycine might depress methionine levels and thus mimic some of the benefits of a low methionine diet which has been reported to extend median and maximum lifespan in rats. [Wikipedia article]

    Green tea extract: includes polyphenols extracted from green tea; has anti-oxidant properties where some constituents scavenge reactive oxygen species. [Wikipedia article]

    INT-767 FXR/TGR5 agonist: a bile acid analog which is a dual agonist of farnesoid X receptor (FXR) and the G protein-coupled receptor TGR5 which has been shown to affect energy metabolism, glucose homeostasis, bile composition/secretion, and inflammation.

    Inulin: a source of dietary fiber produced by many types of plants. [Wikipedia article]

    Medium-chain triglyceride oil: a mixture of triglycerides composed of fatty acids with a chain length of 6-10 carbons; reported use for weight control. [Wikipedia article]

    Metformin: an anti-diabetes drug that increases response to insulin in tissues. [Wikipedia article]

    Metformin plus Rapamycin: the combination of metformin and rapamycin tested the hypothesis that addition of metformin would ameliorate some of the negative effects of rapamycin on glucose metabolism.

    Methylene blue: an agent that increases in vitro fibroblast lifespan and increases activity of mitochondria complex IV; reported to protect against oxidative damage. [Wikipedia article]

    Minocycline: antibiotic in the same class as tetracycline and doxycycline.

    MitoQ: small anti-oxidant molecule (also known as Coenzyme Q10) that accumulates in mitochondria in cultured cells and in vivo.

    Nitroflurbiprofen: is a nitric oxide-releasing flurbiprofen derivative and a nonsteroidal anti-inflammatory agent.

    Nordihydroguaiaretic acid (NDGA): a potent antioxidant, anti-inflammatory molecule, NDGA was originally isolated from the creosote bush but is now chemically synthesized. [Wikipedia article]

    Oxaloacetic acid: an intermediary in oxidative metabolism such as gluconeogenesis, urea cycle, glyoxylate cycle, amino acid synthesis, fatty acid synthesis and citric acid cycle. [Wikipedia article]

    Protandim: a mixture of five botanical extracts designed to activate the Nrf2 (Nuclear factor erythroid 2-related factor 2) transcription factor, which mediates responses to oxidative and other forms of stress. [Wikipedia article]

    Rapamycin: represses the mTOR complex, a key nutrient sensing pathway impacting protein synthesis. [Wikipedia article]

    Resveratrol: a natural phenol and phytoalexin produced by several plants in response to injury; examples are skin of grapes, blueberries, raspberries, mulberries. [Wikipedia article]

    Simvastatin: a lipid-lowering medication. [Wikipedia article]

    TM5441: an inhibitor of PAI-1, the primary inhibitor of tissue and urokinase plasminogen activators.

    Ursodeoxycholic acid (UDCA): Bile acids, including UDCA, are products of cholesterol catabolism that activate xenobiotic detoxification pathways and are involved in regulatation of lipid, glucose and energy metabolism. [Wikipedia article]

    Ursolic acid: present in many plants; reported to decrease d-galactose-induced neurotoxicity in mice; inhibit cognitive impairment induced by a high-fat diet; increase skeletal muscle mass and function while improving glucose tolerance and reducing obesity. [Wikipedia article]
