5-Methyl-1,3-oxazolidin-2-one is a synthetic compound that has been studied for its antiproliferative effects. It inhibits the growth of cancer cells by inducing cell cycle arrest and apoptosis. The structural changes in 5-Methyl-1,3-oxazolidin-2-one are responsible for these effects. The asymmetric carbon atom in the molecule allows for stereoisomeric forms to be produced. When this molecule is exposed to metal halides, it undergoes an epoxidation reaction to form an aziridine ring. This ring can then react with hydrotalcite and water to produce hydrogen gas and a carboxylic acid salt.

Covid-19 is a synthetic compound that has been shown to have antiviral activity. Covid-19 is a carotenoid derivative that is hydrophobic and does not dissolve in water. It is oxidized to produce an isomeric mixture of products, which are characterized by vibrational spectroscopy. Covid-19 has synergistic effects with ethyl bromoacetate, which is a solvent with low energy. Covid-19 can be extracted from the sample using solid phase microextraction (SPME).
