<p>1-Hexen-3-one is a carbonyl compound that has been shown to act as an estrogen receptor modulator. It has been isolated from the reaction product of hexene and formaldehyde, in which the intramolecular hydrogen is transferred to the carbon atom adjacent to the carbonyl group. 1-Hexen-3-one has been shown to induce muscle cell proliferation in vitro and inhibit liver microsomal protein synthesis in vivo. The 1-hexen-3-one can be prepared by reacting hexene with formaldehyde. The yield of this reaction is about 80%.<br>2 HCHO + C6H12 → C6H14O + 2 HCOOH</p>

<p>DL-Alanine methyl ester hydrochloride is a cytotoxic drug that is used to treat cancer. It inhibits the growth of cancer cells by binding to guanine in the cell's DNA and preventing its incorporation into DNA during replication. The substance also inhibits amino acid transport, causing a shortage of amino acids for protein synthesis. This leads to cell death by nucleophilic attack on the bond between two amino acids. DL-Alanine methyl ester hydrochloride has been shown to be effective against murine leukemia, HIV, and Herpes simplex virus type 1 (HSV-1). DL-Alanine methyl ester hydrochloride has two geometric isomers: L-alanine methyl ester hydrochloride and D-alanine methyl ester hydrochloride. These substances have different reactivities due to their different geometric shapes. Magnetic resonance spectroscopy can be used to differentiate between these substances in vivo, as well as in vitro.</p>
