TL;DR: Two pairs of racemic spirodienone neolignans with a rare 2-oxaspiro[4.5]deca-6,9-dien-8-one motif, named (±)-subaveniumins A and B, were isolated from the bark of Cinnamomum subavenium and exhibited moderate inhibitory effects against NO production in RAW264.

A biphenyl type neolignan and a biphenyl ether from Magnolia henryi
TL;DR: A biphenyl type neolignan 5,5′-diallyl-2,2′)-dihydroxy-3-methoxybiphenyl and a new related ether 4′,5dially l-2-hydroxy -3methoxyl ether were isolated from the bark of magnolia henryi in addition to magnolol as discussed by the authors.

Compounds and methods for the treatment of inflammatory and immune disorders
TL;DR: In this paper, 2,5-Diaryl tetrahydrofurans, 1,3-diaryl cyclopentanes, 2,4-direl pyrrolidines, and 2.5-dimethyltetrahydrothiophenes are disclosed that reduce the chemotaxis and respiratory burst leading to the formation of damaging oxygen radicals of polymorphonuclear leukocytes during an inflammatory or immune response.
