<p>Ethyl 1H-tetrazole-5-acetate (ETZA) is a ligand that binds to the active site of prolyl hydroxylase, which is an enzyme involved in collagen synthesis. ETZA inhibits the activity of this enzyme by binding to its heme cofactor, leading to a decrease in the production of collagen and thus inhibiting tumor growth. It has been shown that ETZA has no effect on healthy cells or normal tissues. In vitro studies have shown that ETZA can inhibit cancer cell growth and cisplatin resistance in vivo. ETZA also has a structural similarity to chloride ions and thus may be able to inhibit chloride channels such as those found in cancer cells.</p>

<p>1,2-Dimethylpiperidin-4-one is a chiral compound that can be used to make optically active compounds. It is an important intermediate in the synthesis of piperidones. The 1,2-dimethylpiperidin-4-one has two diastereomers, which are called cis and trans. The cis configuration has a methyl group in the same plane as the amine group, whereas the trans configuration has the methyl group in a different plane. The cis configuration is more stable than the trans one and this is because it is less sterically hindered by the bulky groups on either side of it. This means that if you want to make an optical pure compound, it will be easier to do so using cis rather than trans 1,2-dimethylpiperidin-4-one.</p>
