Chemical Structure
Myrigalone A
Synonym(s): MyA
- CAS No.: 34328-57-9
- Formula:C18H20O4
- Molecular Weight:300.35
IUPAC Name: 2,2,4-trimethyl-6-(3-phenylpropanoyl)cyclohexane-1,3,5-trione
InChIKey: CTSXBYQFSBUGKB-UHFFFAOYSA-N
SMILES: O=C(CCC=1C=CC=CC1)C2C(=O)C(C(=O)C(C2=O)(C)C)C
Biological Activity: Myrigalone A (MyA) is a plant ethylene biosynthesis inhibitor and natural herbicide. Myrigalone A possesses antioxidant, antifungal, and antimicrobial activities. Myrigalone A interferes with auxin homeostasis during seed germination. Myrigalone A delays seed germination, inhibits the formation of roots, hypocotyls, and root hairs, and causes developmental delay in specific organisms. Myrigalone A triggers the induction of detoxification programs, alters the metabolism of gibberellins, cis-(+)-12-oxophytodienoic acid, and jasmonic acid, disrupts the antioxidant system and oxidative signaling, and impairs the function of aquaporins and water uptake in imbibed seeds. Myrigalone A can be used in studies related to herbicides and plant growth regulators[1][2][3].
