LMK-235

SKU: orb1226326

Description

A selective HDAC5 and HDAC4 inhibitor with IC50 of 4.22 nM and 11.9 nM respectively; less potent for HDAC1/11/2/8; demonstrates activity against chemoresistant cancer cell lines in an MTT assay for cytotoxicity using human ovarian cancer cell lines A2780 and cisplatin resistant A2780CisR (IC50 =0.49 and 0.32 uM respectively).

Bioactivity

• In Vivo:
  LMK235 (5 and 20 mg/kg) restores survival and maturation of postmitotic granule neurons in Cdkl5-/Y mice. LMK235 also restores synapse development in the dentate gyrus and hippocampus of Cdkl5-/Y mice. Furthermore, LMK235 restores hippocampus-dependent learning and memory in Cdkl5-/Y mice.
• In Vitro:
  LMK-235 shows cytotoxic activity against human ovarian cancer cell lines A2780 and A2780 CisR, with IC50s of 0.49 μM and 0.32 μM, respectively. LMK-235 inhibits HDAC in A2780 and A2780 CisR cell lines, with IC50s of 0.65 μM and 0.32 μM, respectively. LMK-235 produces a higher reduction in cell viability in comparison to the combination of cisplatin and vorinostat in all cell lines. LMK-235 (0, 0.625, 1.25, 2.5, 5, 10, and 20 μM) reduces the proliferation of BC cells in a dose- and time-dependent manner. LMK-235 (0-800 nM) also inhibits the growth of BC cells. Moreover, LMK-235 synergizes with bortezomib in BC cell lines. LMK235 (2, 20 nM) decreases in HDAC4 nuclear accumulation in Cdkl5 -/Y NPCs, completely restores the reduced number of neurons generated from Cdkl5 -/Y NPCs. LMK235 also restores histone 3 acetylation in Cdkl5 -/Y NPCs. LMK235 causes a notable increase in the isoform IV, but does not affect BDNF isoforms I or II.
