    SN 2 purchased from MedChemExpress. Usage Cited in: Gene. 2023 Feb 20;147291.

    SN-2 (5, 10, 20 μM) dose-dependently upregulates the expression of three inflammatory marker genes, IL-1β, IL-6 and TNFα in A549 cells.

    SN 2 purchased from MedChemExpress. Usage Cited in: Antiviral Res. 2020 Oct;182:104922.  [Abstract]

    SN-2 treatment could decrease both DENV2 RNA and DENV2 E protein in a dose-dependent manner under noncytotoxic concentrations in A549 cells. SN-2 treatment also dose-dependently inhibits both ZIKV RNA and ZIKV E protein in A549 cells.

    SN 2 is a potent activator of TRPML3 ion channel with an EC50 of 1.8 μM[1]. SN 2 also acts as a potent inhibitor of Dengue virus 2 (DENV2) and Zika virus (ZIKV)[2].

    IC50 & Target

    EC50: 1.8±0.13 μM (TRPML3), >29.9 μM (TRPML1)[1]

    In Vitro

    The conductance of TRPML3 channels is estimate, when activated with 10 µM SN-2 is approximately 10 pS at −80 mV. TRPML3-expressing HEK293 cells are perfused with a series starting with compound alone (in SBS), with compound in ELS, and finally with ELS alone. Two representative compounds, SF-24 and SN-2, are tested. SF-24 is one of the least effective compounds, and SN-2 is one of the most active ones. SN-2 has a similar synergistic effect, also reaching up-to 10-fold enhancement of the combined response when compared with the individual responses, reaching average current densities of up to 3 nA/pF at −80 mV. Dominant negative TRPML3(D458K) is highly effective in eliminating SN-2-induced activity in epidermal melanocytes, suggesting that SN-2 activates a channel that is not responsive in presence of TRPML3(D458K). Such a dominant negative action might be attributed to potential heteromerization of TRPML3(D458K) with an SN-2-responsive channel[1].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
