This substance also has an inhibitory effect on water vapor, inhibiting the formation of water molecules from hydrogen atoms and oxygen atoms. Potassium trimethylsilanolate can be used as an anti-cancer agent by preventing cell division in tumor cells and preventing cancer metastasis through inhibition of protease activity.</p>

<p>N-Hexylboronic acid is an organometallic compound that has been used as a model system to study the catalytic mechanism of the Suzuki coupling reaction. It has also been shown to be a substrate film for use in the suzuki coupling reaction when combined with Raney nickel, which can be used to synthesize organic compounds. N-Hexylboronic acid has been shown to inhibit the activity of pancreatic lipase, but not cholesterol esterase or cholesterol ester hydrolase. The skeleton of this molecule is made up of six carbon atoms and one boron atom. Hydrogen chloride and aliphatic hydrocarbons are inhibitors of N-hexylboronic acid.</p>
