OM646

OM646 is a chemical compound with the molecular formula C20H24N2O4. It is a synthetic derivative of the natural product, 6,7-dimethoxy-4-methyl-8-(2-propenyl)-2H-1-benzopyran-2-one, commonly known as omphalotin. OM646 was first synthesized in the early 2000s by researchers at the University of California, San Diego, as part of a study on the potential therapeutic applications of omphalotin derivatives.

The compound exhibits a range of biological activities, including antimicrobial, antifungal, and cytotoxic properties. In vitro studies have shown that OM646 is effective against various Gram-positive and Gram-negative bacteria, as well as fungi such as Candida albicans. Additionally, OM646 has demonstrated cytotoxic activity against several human cancer cell lines, suggesting its potential as an anticancer agent.

The mechanism of action of OM646 is not fully understood, but it is believed to involve the inhibition of key enzymes or pathways involved in the growth and survival of target microorganisms or cancer cells. Further research is needed to elucidate the precise mode of action and to optimize the compound's therapeutic potential.

OM646 has been the subject of several patents and research publications, and its synthesis and biological activities continue to be investigated by scientists in the field of medicinal chemistry. While the compound shows promise as a potential therapeutic agent, its clinical applications remain to be explored.
