Signum Biosciences, Inc. is a biotechnology company in Monmouth Junction, NJ.[1] The company has developed drugs and dietary supplements targeted at dermatological conditions and neurodegenerative disorders. Signum agreed in 2019 to stop making certain claims about its EHT supplement, and to stop allowing its multi-level marketing partner firm Neora (formerly Nerium International) to make such claims.

History

[edit]

Signum was founded in 2003 based on research done in the lab of Jeffry B. Stock, a professor at Princeton University, on compounds that can modulate protein phosphatase 2 (PP2).[2][3] Gregory Stock, Stock's brother, served as the first CEO.[4]

In 2008 Signum partnered with Rohto Pharmaceutical Co. of Japan to commercialize Signum's product, n-acetyl-s-farnsylcysteine (Arazine); that product was launched in Japan in 2010.[5]

In 2011 Signum partnered with GlaxoSmithKline to develop drugs screened against PP2 for neurodegenerative diseases.[citation needed]

In 2011 Signum spun out a dermatology company, originally called Argyle Therapeutics[6][7] but after 2012 called Signum Dermalogix.[2] In 2012 Argyle licensed one of its compounds, SIG990, to Brickell Biotech for development as a drug to treat rosacea.[7]

Neora (Nerium) partnership and FTC injunction

[edit]

In 2015 Signum partnered with Neora, LLC (then known as Nerium International) to launch a dietary supplement called eicosanoyl-5-hydroxytryptamide (EHT).[8] EHT is derived from coffee and inhibits demethylation of the enzyme protein phosphatase 2 (PPP2CA; PP2A).[9] EHT has shown neuroprotective effects in a mouse model of Parkinson's disease[10][11] and a rat model of Alzheimer's disease.[12]

In October 2019 the Federal Trade Commission won a permanent injunction against Signum BioSciences, Signum Nutralogix, and affiliated companies including Neora. The injunction prohibits claims or representations of EHT's efficacy in treating or mitigating Alzheimer's disease, Parkinson's disease, or brain injury including CTE and concussion, unless those claims are backed up by randomized, double-blind, placebo-controlled human clinical testing.[13][14]

Activation of Balpha containing PP2A was reached by inhibiting PP2A demethylation mediated by eicosanoyl-5-hydrotytryptamide (EHT). EHT administration to alpha-synuclein transgenic mice reduced alpa-synuclein Ser129 phosphorylation, its subsequent aggregation, and ameliorated the associated neuropathology and behavioral aberrations. EHT action on PP2A is mediated by its antagonistic effect on PME. reported to occur at IC50 3.9µM.

P2A enzymes have the particularity that their enzymatic activity is positively regulated by its methylation which is itself regulated via the opposing activities of a PP2A-specific methyltransferase and a PP2A-specific methylesterase (PME). Accordingly, treatment of mice with the PME inhibitor eicosanoyl-5-hydroxytryptamide (EHT) increases PP2A methylation as well as decreased α-syn-pS129 levels in brain and a concurrent reduction in synuclein pathology{{cite journal}}: CS1 maint: unflagged free DOI (link)
