What is SINEFUNGIN?

Description

Sinefungin (58944-73-3) is a nucleoside S-adenosyl-1-methionine analog. Potent, competitive methyltransferase (protein, DNA, and RNA methyltransferases) inhibitor.1,2?IC50?< 1.0 and 2.5 μM for PRMT1 and SET7/9, respectively.3?Sinefungin binds with greater affinity to the adenine-specific DNA methyltransferase M.TaqI than S-adenosyl-L-homocysteine.4?Inhibits biofilm formation by?Streptococcus pneumoniae.5

The Uses of SINEFUNGIN

Sinefungin, a polar nucleoside antifungal active with broad biological activity, was isolated from a number of species of Streptomyces in the early 1970s. Sinefungin acts by inhibiting a wide range of methyltransferases, including the methylation of bases in DNA and RNA which alters cytosine deamination and gene expression. Sinefungin is widely used as a bioprobe to block methyltransferase-dependent pathways.

The Uses of SINEFUNGIN

Sinefungin is a natural nucleoside analog of S-adenosylmethionine and inhibits Streptococcus pneumoniae biofilm growth. Its derivatives can be used as inhibitors and structure probes for human protein lysine methyltransferase SETD2.
