Guanabenz 是一种 α-2 肾上腺素受体激动剂,具有口服活性。Guanabenz 具有抗高血压和抗寄生虫活性。Guanabenz 干扰内质网应激信号传导,对心肌细胞具有保护作用。Guanabenz 也被用于高血压的研究。
生物活性 | Guanabenz is an orally activeα-2-adrenoceptoragonist. Guanabenz has antihypertensive effect and antiparasitic activity. Guanabenz interferes ER stress-signalling and has protective effects in cardiac myocytes. Guanabenz also is used for the research of high blood pressure[1][2][3]. |

体外研究 (In Vitro) | Guanabenz (0.5-50 μM, 24 h) is treated with increasing concentrations for 24 hours not affect cell viability[1]. Guanabenz (0.5-50 μM, 24 h) alone not affects the UPR targets, neither on mRNA or protein level nor the phosphorylation status of eIF2a. Guanabenz also not induces GADD34 or the constitutively active form CReP[1]. Guanabenz (0.5-50 μM, 24 h) alone not induces ER stress in neonatal rat cardiomyocytes[1].
Cell Viability Assay[1] Cell Line: | Neonatal rat cardiac myocytes (NRCM) | Concentration: | 0.5–50 μM | Incubation Time: | 24 h | Result: | Did not affect cell survival. |
RT-PCR[1] Cell Line: | Neonatal rat cardiac myocytes (NRCM) | Concentration: | 0.5–50 μM | Incubation Time: | 24 h | Result: | Did not affect levels of UPR targets. |
Western Blot Analysis[1] Cell Line: | Neonatal rat cardiac myocytes (NRCM) | Concentration: | 0.5–50 μM | Incubation Time: | 24 h | Result: | Increased the levels of low panel concentration-dependent UPR targets proteins. |

体内研究 (In Vivo) | Guanabenz (5 mg/kg/day; i.p.; for 3 weeks) can reproducibly reduce brain cyst burden[2]. Guanabenz (5 mg /kg/d, i.p., oral; 10 mg/kg/d, gavage; for 3 weeks) reverses Toxoplasma-induced hyperactivity in latently infected mice[2]. Guanabenz (100 and 320 μg/kg and 1 mg/kg, i.v., over a period of 5 min at intervals of 40 min) reduces sympathetic outflow, heart rate and blood pressure in debuffered cats[3].
Animal Model: | BALB/cJ mice[2] | Dosage: | 5 mg/kg | Administration: | 5 mg/kg/day; i.p. ; for 3 weeks | Result: | Reduced the latent brain cysts in both male and female BALB/cJ mice. |
Animal Model: | BALB/cJ mice[2] | Dosage: | 5 mg/kg; 10 mg/kg | Administration: | 5 mg /kg/d, i.p., oral; 10 mg/kg/d, gavage; for 3 weeks | Result: | Reversed parasite-induced hyperactivity to near-baseline levels. |
Animal Model: | Cats[3] | Dosage: | 100 and 320 μg/kg and 1 mg/kg | Administration: | 100 and 320 μg/kg and 1 mg/kg, i.v., over a period of 5 min at
intervals of 40 min | Result: | Declined markedly blood pressure and nerve activity. |
