KL-50 is a selective toxin toward tumors that lack the DNA repair protein O6-methylguanine-DNA-methyltransferase (MGMT), which reverses the formation of O6-alkylguanine lesions. KL-50 activates DNA damage response pathways and cycle arrest in MGMT-cells, independent of mismatch repair (MMR). KL-50 is promising for research of brain tumors that lack the DNA repair protein MGMT.

Formic acid is the simplest carboxylic acid. Formate is an intermediate in normal metabolism. It is responsible for both metabolic acidosis and disrupting mitochondrial electron transport and energy production by inhibiting cytochrome oxidase activity the terminal electron acceptor of the electron transport chain.

Sericoside, a triterpenoid compound, is obtained from Terminalia and exhibits potent anti-inflammatory properties. Additionally, sericoside displays robust lipolytic activity, thereby aiding in the reduction of skin wrinkles and improvement of skin texture.
