Tubastatin A |
| Katalog-Nr.GC10839 |
Tubastatin A is a potent and selective HDAC6 inhibitor with an IC50 value of 15 nM . Tubastatin A is also a novel GPX4 inhibitor that directly binds to GPX4 and induces ferroptosis in breast cancer cells.

Tubastatin A is a potent and selective HDAC6 inhibitor with an IC50 value of 15 nM [1]. Tubastatin A is also a novel GPX4 inhibitor that directly binds to GPX4 and induces ferroptosis in breast cancer cells[2].
Tubastatin A protected against HCA induced neuronal cell death in a dose-dependent manner. Tubastatin A induced the hyperacetylation of α-tubulin at 2.5 μM[1]. Tubastatin A (32.5µM, 30µM) can inhibit cell colony formation and migration ability and promote apoptosis[3]. Tubastatin A can effectively upregulate the levels of SOD1 and HO-1 and reduce the oxidative stress of chondrocytes [4]. Tubastatin A at 10 μM also significantly inhibited cell proliferation in cholangiocarcinoma cells[5].
Tubastatin A (50mg/kg/day) treatment effectively reduces the expression of HDAC6 in the cartilage of osteoarthritis mice and improves osteoarthritis in mice with surgically destroyed medial meniscus (DMM)[4]. Tubastatin A treatment reduced tumor growth and induces ciliogenesis in rat orthotopic model of cholangiocarcinoma at 10 mg/kg[5].
