trans-2,3-Dimethyloxirane

Description:

Trans-2,3-Dimethyloxirane, also known as trans-2,3-dimethyloxirane or simply trans-epoxide, is a cyclic ether characterized by a three-membered ring structure containing an oxygen atom and two carbon atoms, each substituted with methyl groups. This compound is a stereoisomer of 2,3-dimethyloxirane, specifically featuring a trans configuration, which influences its physical and chemical properties. It is typically a colorless liquid with a distinctive odor and is known for its reactivity, particularly in undergoing ring-opening reactions, which can be catalyzed by acids or bases. The presence of the epoxide group makes it a valuable intermediate in organic synthesis, allowing for the formation of various functional groups through nucleophilic attack. Additionally, trans-2,3-Dimethyloxirane is used in the production of polymers and other chemical compounds. Its handling requires caution due to potential health hazards associated with exposure, including irritation to the skin and respiratory system. Overall, this compound exemplifies the unique properties of epoxides, making it significant in both industrial and laboratory settings.

trans-2,3-Epoxybutane

CAS: 21490-63-1

Pinostrobin is a chalcone that has been shown to inhibit the growth of certain fungi by inhibiting the enzyme activities involved in cell walls synthesis. Pinostrobin is converted to trans-2,3-epoxybutane (EPB) by intramolecular hydrogen transfer. EPB has an antifungal activity that is stronger than pinostrobin and it can be used as a fungicide against certain fungal diseases. This compound may also have anticancer effects. EPB binds to mammalian cells by forming hydrogen bonds with the amino acids, glutamine and asparagine, which are found in abundance on the surface of mammalian cells. EPB's binding to these amino acids prevents the formation of hydrogen bonds between glutamine and asparagine residues on adjacent protein molecules, leading to destabilization of the cell membrane and cell death.
