As with catalytic cracking, the main reactions occur by carbonium ion and beta scission, yielding two fragments that could be hydrogenated on the catalyst surface.

Pyroglutamic acid (also known as PCA, 5-oxoproline, pidolic acid, or pyroglutamate for its basic form) is a ubiquitous but little studied natural amino acid derivative in which the free amino group of glutamic acid or glutamine cyclizes to form a lactam.

Gene transcription is a process that transfers the genetic information into carriers such as mRNA and guides subsequent cellular metabolic activities. Interruption of gene transcription will result in catastrophic impacts and lead to cell death. Many of the transcription inhibitors have decent pharmacological effects against tumor growth and a number of anti-cancer drugs have been identified or developed to restrain transcription, among which amatoxins have been shown to exhibit high tumor inhibition potency
