Macelignan(Anwuligan) is a natural compound isolated from Myristica fragrans Houtt; possesses therapeutic potentials against neurodegenerative diseases with oxidative stress and neuroinflammation. IC50 value: Target: in vitro: Macelignan significantly attenuated the ROS production and neurotoxicity induced by glutamate in HT22 cell [1]. At 24 h of biofilm growth, S. mutans, A. viscosus and S. sanguis biofilms were reduced by up to 30%, 30% and 38%, respectively, after treatment with 10 microg/mL macelignan for 5 min [2]. Cisplatin-induced phosphorylation of c-Jun N-terminal kinase1/2 (JNK1/2) and extracellular signal-regulated kinase1/2 (ERK1/2) was abrogated by pretreatment with macelignan, however, that of p38 was not significantly affected [3]. in vivo: Macelignan attenuated the expression of phosphorylated c-Jun in cisplatin-treated mice [3]. Daily administration of macelignan reduced the spatial memory impairments induced by the chronic LPS infusions [4].
