1,1-Dimethylbiguanide hydrochloride (Metformin) is an antidiabetic agent that reduces blood glucose levels and improves insulin sensitivity. Its metabolic effects, including the inhibition of hepatic gluconeogenesis, are mediated at least in part by activation of the LKB1-AMPK (AMP-activated protein kinase) pathway. Activation of this pathway also appears to be involved in the antiproliferative and proapoptotic actions of metformin in cancer cell lines.

L-Glutamine, the uncharged and amidated analog of L-glutamic acid, is an important amino acid for the incorporation of NH4+ into biomolecules. It is biosynthesized from NH4+ and glutamate via the enzyme glutamate synthetase. In turn, degradation of glutamine to free the ammonia moiety is mediated by glutaminase. Glutamine also participates in acid-base regulation in vivo.

Sodium Valproate is reported to cause inositol depletion, activate the ERK pathway, inhibit GSK-3α and GSK-3β. Valproic Acid has been reported to be a potent inhibitor of HDAC (histone deacetylase) in vitro (IC50 = 400 μM for HDAC1), thereby relieving HDAC-dependent transcriptional repression and causes the hyperacetylation of histones in cultured cells.

For sampling bulk goods, cross-sectional samples can be taken from different sample depths. Suitable for use with a range of sample substrates from fine powder to coarse grain. Multi sampler has three or five separate chambers for taking samples at multiple depths in one action. Uno sampler has one chamber for taking a sample at one specified depth. All layer sampler has no chambers, three or five inlets and this allows one sample to be taken at multiple depths. Jumbo sampler has no chambers and three, five or seven inlets; with a 50 mm tube diameter this is ideal for larger grain sizes and quantities.

5-Fluorodeoxyuridine is an antineoplastic agent, which acts as an anti-metabolite. When administrated by rapid injection it acts as flurouracil, but when infused slowly, usually intra-arterially, it is converted to active F-dUMP, which leads to enhanced inhibition of DNA synthesis. It inhibits DNA synthesis by blocking thymidylic acid synthetase.
