Ionomycin is an ionophore produced by the bacterium Streptomyces conglobatus. The molecules act as a motile Ca2+ carrier and enhances Ca2+ influx by direct stimulation of store-regulated cation entry across biological membranes. It is highly specific for divalent cations. Ion selectivity is as follows: Ca2+ > Mg2+ >> Sr2+ = Ba2+ Binding of Sr2+ and Ba2+ is insignificant and binding to monovalent cations or rubidium is negligible. La2+ is also bound to some extent. Complexation with a cation is always in a 1:1 stoichiometry and pH-dependent. Essentially no binding of Ca2+ occurs below pH 7.0 and maximum binding takes place at pH 9.5. At the micromolar level, ionomycin can activate Ca2+/Calmodulin dependent kinase and phosphatase to stimulate gene expression. Ionomycin has been shown to induce central demyelination, inhibit adrenal bovine TREK-1 channels, and to regulate cell division of mature human B cells [1]. It is used to study the effects of calcium flux on endoplasmic reticulum (ER) stress, mitochodrial stress and intrinsic apoptosis mechanisms. It is also used to stimulate the intracellular production of the cytokines, interferon, perforin, IL-2, and IL-4 usually in conjunction with PMA.

D-Fagomine (1,2-dideoxynojirimycin) is a six-membered ring iminocyclitol that was first isolated from seeds of buckwheat (Fagopyrum sculentum Moench, Polygonaceae) and is also present in other plant sources such as mulberry (Morus Alba, Moraceae) leaves and gogi (Lycium chinense) roots. D-fagomine is present in common buckwheat-based foodstuffs in amounts ranging from 1 to 25 mg/kg or mg/L, it is stable during boiling, baking, frying and fermentation, and it is biosynthesised upon sprouting. The estimated total intake of D-fagomine resulting from a diet that includes such foodstuffs would be between 3 and 17 mg per day (mean for both genders; range from P5 to P95). In animal studies D-Fagomine lowers postprandial blood glucose. D-fagomine agglutinated Enterobacteriaceae (Escherichia coli, Salmonella enterica serovar Typhimurium), while it did not show this effect on Bifidobacterium spp. or Lactobacillus spp. D-fagomine significantly inhibited the adhesion of Enterobacteriaceae and promoted the adhesion of Lactobacillus acidophilus to intestinal mucosa. D-Fagomine did not show any effect on bacterial cell viability. D-fagomine may be used as a dietary ingredient or functional food component to reduce the health risks associated with an excessive intake of fast-digestible carbohydrates, or an excess of potentially pathogenic bacteria.

Clevudine F18 is a radioconjugate comprised of the synthetic pyrimidine analog clevudine (1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)thymine, d-FMAU) labeled with the radioisotope fluorine F18. Upon administration, fluorine F18 clevudine is distributed and taken up by cells based on the rate of the cell’s DNA synthesis. The amount is then measured using positron emission tomography (PET). The compound is investigated as an imaging agent in prostate, breast cancers, and other malignant neoplasms.

Talopram (Lu 3-010) is a selective inhibitor norepinephrine transporter belonging to the antidepressants of the thymoleptic group.

24-Hydroxycalcidiol (24,25-dihydroxy vitamin D3) is a circulating metabolite of vitamin D3. 24,25(OH)2D3 functions by activation of Vitamin D receprtor and promotion of ostecalcin expression, but is less effective than other D3 metabolite, 1alpha,25(OH)2D3. There is conflicting evidence on efffect of 24-hydroxycalcidiol on bone metabolism. In several animal studies it was demonstrated that 24-hydroxycalcidiol was able to stimulate calcification of bone and restore the reduction in bone mineral apposition rate. However, no beneficial effect of 24R,25(OH)2D3 treatment of postmenapausal women on bone mineral density or bone loss and calcium metabolism were observed.

Fucoxanthin isis a marine carotenoid mainly found in brown algae, giving them a brown or olive-green color. Fucoxanthin is investigated for its anti-inflammatory, antinociceptive and anti-cancer effects. In vivo studies have demonstrated that oral administration of fucoxanthin inhibited carcinogenesis in an animal model of duodenal, skin, colon and liver cancer. Fucoxanthin causes antitumor and anticarcinogenic effects by inducing G1 cell-cycle arrest and apoptosis by modulating expression of various cellular molecules and cellular signal transduction pathways, but the exact mechanism of anti-cancer action of fucoxanthin is not fully elucidated. Fucoxanthin regulates lipids metabolism, the effect most likely mediated by AMK-activated protein kinase. A clinical trial of fucoxanthin against non-alcoholic fatty liver disease is ongoing.

Iodohippuric acid I-125 (I-I25 Hippuran) is radioisotope that was used as a renogram probe in nefhrography in 1960s-1970s. It is an analog of I-131 labeled I(131) hippuran which has been recognized as the radiopharmaceutical standard for the measurement of effective renal plasma flow in subjects with renal failure but which use has been compromised by the suboptimal imaging characteristics of the 364-keV photon of 131I and the delivery of relatively high radiation doses to kidneys and thyroid in patients with impaired renal function. It was shown that radiation risk was rendered to a minimum with the use of the "cocktail" of 169U-EDTA and 125I-hippuran.

Lupeol, a biologically active dietary triterpenoid, is found in many medicinal plants and different fruits such as olives, mangos, and strawberries. Lupeol exhibits a wide spectrum of pharmacological properties including anti-inflammatory, anti-cancer, anti-diabetic, anti-microbial, cardioprotective, and hepatoprotective activities. Lupeol inhibits LPS-induced microglial neuroinflammation via the P38-MAPK and JNK pathways and has therapeutic potential to treat various neuroinflammatory disorders. Lupeol possesses antiskin tumor-promoting effects in CD-1 mouse and inhibits conventional as well as novel biomarkers of tumor promotion. It strongly suppressed lipogenesis by modulating the IGF-1R/phosphatidylinositide 3 kinase (PI3K)/Akt/sterol response element-binding protein-1 (SREBP-1) signaling pathway in SEB-1 sebocytes, and reduced inflammation by suppressing the NF-κB pathway in SEB-1 sebocytes and HaCaT keratinocytes. Lupeol exhibited a marginal effect on cell viability and may have modulated dyskeratosis of the epidermis. These results demonstrate the clinical feasibility of applying lupeol for the treatment of acne.

Secoisolaricircsinol is one of the most abundant dietary lignans in various foods, such as plant seeds, whole grains, legumes, vegetables, and fruits. Secoisolariciresinol is the major lignin found in flaxseed and is present in a polymer that contains Secoisolariciresinol diglucoside. Secoisolariciresinol and Secoisolariciresinol diglucoside are known to have a number of health benefits, including reduction of the serum cholesterol levels, delaying of the onset of type 2 diabetes, and reduction of the formation of hormone-sensitive cancers such as breast, prostate, and colon cancers. Following the consumption of Secoisolariciresinol diglucoside, it is further converted by the bacteria in the colon of humans and other animals into aglycone Secoisolariciresinol and the mammalian lignans, enterodiol and enterolactone. The structures of enterodiol and enterolactone are similar to that of estradiol, an endogenous estrogen. This structural similarity accounts for the ability of these compounds to bind to estrogen receptors and to exert weak estrogenic or anti-estrogenic effects, depending on the presence of stronger estrogen. It is well known that Secoisolariciresinol has an estrogen-like activity and stimulates the cell growth of human breast cancer MCF-7 cells.

Iodophthalein was used as an iodine-containing X-ray contrast agent in icteric subjects. There is also existed mention, that iodophthalein has also been used as a wound treatment, and for the treatment of intestinal catarrhs. But nowadays more modern drugs are being used.
