Apicidin (OSI 2040) is a fungal metabolite, acts as a histone deacetylase (HDAC) inhibitor, with antiparasitic activity and a broad spectrum antiproliferative activity[1].
Gnetol is a phenolic compound isolated from the root of Gnetum ula Brongn. Gnetol potently inhibits COX-1 (IC50 of 0.78 μM) and HDAC. Gnetol is a potent tyrosinase inhibitor with an IC50 of 4.5 μM for murine tyrosinase and suppresses melanin biosynthesis. Gnetol has antioxidant, antiproliferative, anticancer and hepatoprotective activity. Gnetol also possesses concentration-dependent α-Amylase, α-glucosidase, and adipogenesis activities[1][2][3].
ITF3756 is a selective histone deacetylase 6 (HDAC6) inhibitor bearing a pentaheterocyclic scaffold.
Trichostatin A is a potent and specific inhibitor of HDAC class I/II, with an IC50 value of 1.8 nM for HDAC.
KPZ560 is a potent inhibitor of HDAC1 and HDAC2, with IC50s of 12 nM and 68 nM, respectively. KPZ560 can increase in the spine density of granule neuron dendrites of mice and inhibitor cell growth of breast cancer cell line MCF[1].
RSC133 exhibits dual activity by inhibiting histone deacetylase and DNA methyltransferase. RSC133 effectively facilitates reprogramming of human somatic cells to pluripotent stem cells and supports the maintenance of an undifferentiated state of human pluripotent stem cells[1].
