Avermectin is a kind of 16-membered ring macrolide

Dimethyl fumarate[DMF] is the methyl ester of fumaric acid^{[1, 2]}. DMF, marketed in Germany under the trade name of Fumaderm, is used for oral therapy of psoriasis in combination with other drugs^[2]. Later it has been used to treat adults with relapsing multiple sclerosis[a chronic inflammatory, demyelinating and neurodegenerative disease of the CNS resulting in neurological disability] since 2013(trade name Tecfidera)^[3]. DMF is thought to have immunomodulatory properties without significant immunosuppression. In preclinical studies, dimethyl fumarate exhibited anti-inflammatory and cytoprotective properties that are generally thought to be mediated via activation of the nuclear factor [erythroid-derived 2]-like 2 transcriptional pathway, which is involved in the cellular response to oxidative stress.
In a non-medical use, DMF has been used as a biocide in furniture or shoes to prevent growths of mold during storage or transport in a humid climate. However, due to incidences of allergic reactions after skin contact the European Union has banned DMF in consumer products since 1998, and since January 2009 the import of products containing DMF has also been banned^[4].
