LL Z1640-2 (5Z-7-oxozeaenol) is a cis-enone resorcylic acid lactone first reported in 1978 and later rediscovered as an irreversible and highly selective TAK 1 inhibitor. TAK1 is a MAPKKK involved in the p38 signalling cascade for pro-inflammation signals such as cytokines. LL Z1640-2 effectively prevents inflammation in animal models.

ChEBI: 5Z-7-oxozeaenol is a macrolide that is the 7-oxo derivative of zeaenol (the 5Z stereoisomer). Isolated from Fungi, it exhibits cytotoxic, antibacterial and inhibitory activity against NF-kappaB. It has a role as a metabolite, an antibacterial agent, an antineoplastic agent and a NF-kappaB inhibitor. It is an aromatic ether, a macrolide, a member of phenols, a secondary alcohol and a secondary alpha-hydroxy ketone.

The anti-inflammatory effects of 5Z-7-oxozeaenol may affect cardiac hypertrophy.
