TBHQ (tert-Butylhydroquinone) 是一种广泛使用的Nrf2激活剂,通过激活Nrf2来免受 Doxorubicin (DOX)-诱导的心脏毒性。TBHQ (tert-Butylhydroquinone) 也是一种ERK激活剂,逆转 Dehydrocorydaline (DHC) 对黑素瘤细胞增殖的抑制作用。
生物活性 | TBHQ (tert-Butylhydroquinone) is a widely usedNrf2activator, protects against Doxorubicin (DOX)-induced cardiotoxicity through activation ofNrf2[1]. TBHQ (tert-Butylhydroquinone) is also anERKactivator; rescues Dehydrocorydaline (DHC)-induced cell proliferation inhibitionin melanoma[2]. |

体外研究 (In Vitro) | TBHQ (t-butylhydroquinone; tBHQ; 0-100 μM; 48 hours; H9c2 cells) alone does not affect H9c2 cells viability. Pre-incubation of the H9c2 cells with various concentrations of tBHQ for 24 hours enhances cell viability which is decreased due to exposure to ethanol in a dose-dependent manner. Treatment with tBHQ markedly enhances the viability of H9c2 cardiomyocytes exposed to ethanol[3]. TBHQ (5 μM; 15 min; H9c2 cells) treatment significantly reduces the amount of apoptotic cells exposed to ethanol[3]. TBHQ (5 μM; H9c2 cells) pre-treatment markedly inhibites the ethanol-induced increase in caspase-3 and Bax expression, and enhances Bcl-2 expression[3].
Cell Viability Assay[3] Cell Line: | H9c2 cells | Concentration: | 0 μM, 0.625 μM, 1.25 μM, 2.5 μM, 5 μM, 10 μM, 20 μM, 50 μM and 100 μM | Incubation Time: | 48 hours | Result: | Enhanced the viability of H9c2 cardiomyocytes exposed to ethanol. |
Apoptosis Analysis[3] Cell Line: | H9c2 cells | Concentration: | 5 μM | Incubation Time: | | Result: | Lowered the amount of apoptotic cells exposed to ethanol. |
Western Blot Analysis[3] Cell Line: | H9c2 cells | Concentration: | 5 μM | Incubation Time: | | Result: | Inhibited the ethanol-induced increase in caspase-3 and Bax expression, and enhanced Bcl-2 expression. |

体内研究 (In Vivo) | TBHQ treatment (50 mg/kg; Intraperitoneal injection; three injections at intervals of 8 h that began 1-h post ICH; CD-1 mice) augments the DNA-Binding activity of Nrf2, attenuates oxidative brain damage and acute neurological deficits afterintracerebral hemorrhage (ICH), attenuates microglial activation with concomitant reduction in the release of proinflammatory cytokine interleukin-1β (IL-1β). TBHQ has the efficacy of post-injury administration in attenuating acute neurological injury after ICH[4].
Animal Model: | Male CD-1 mice (8-10 weeks old)[4] | Dosage: | 50 mg/kg | Administration: | Intraperitoneal injection; three injections at intervals of 8 hours that began 1h post ICH. | Result: | The treatment augmented the DNA-binding activity of Nrf2, attenuated brain oxidative damage, attenuated the microglial activation and the expression of IL-1β. |
