Biological Activity
IC50: 42 nM (FASN) and 81 nM (cellular palmitate synthesis)[1]
ISX-9 promotes neurogenesis in vivo, enhancing the proliferation and differentiation of hippocampal subgranular zone (SGZ) neuroblasts, and the dendritic arborization of adult-generated dentate gyrus neurons. At 2.5-20 μM, ISX-9 has been shown to dose-dependently trigger neurogenesis and block gliogenesis in adult rat hippocampal stem cells through a calcium-activated signaling pathway dependent on myocyte-enhancer factor 2-dependent gene expression[1].
Molecular exploration of ISX-9-induced regulation of neurogenesis (via FACS and microarray of SGZ stem and progenitor cells) suggested the involvement of the myocyte-enhancer family of proteins (Mef2)[1].

Statistical analysis was performed on the rate of KI67- and TUNEL-positive cells in each group of xenograft tumors by immunohistochemical staining (IHC). The corrected total cell fluorescence (CTCF) of BODIPY staining was used to quantitatively detect the lipid content of xenograft tumors in each group. The results showed that TVB-3166 (60 mg/kg; i.g.; 5 weeks) treatment can reduce lipid accumulation, inhibit cell proliferation and increase the apoptosis rate.
