3-Hydroxymethyl-β-carboline

3-Hydroxymethyl-β-carboline is a Benzodiazepine antagonist with a K_i value of ~1470 nM. 3-Hydroxymethyl-β-carboline reverses Flurazepam-induced sleep, cerebrovascular and cerebral metabolic inhibition, and also partially reverses Flurazepam-induced decreases in blood pressure and heart rate. 3-Hydroxymethyl-β-carboline disrupts the anticonvulsant and anxiolytic effects of Diazepam in male mice. 3-Hydroxymethyl-β-carboline has no effect on sodium-dependent high-affinity choline uptake in rat cortical or hippocampal synaptosomes.

In Vitro

3-Hydroxymethyl-β-carboline inhibits [³H]-diazepam binding to benzodiazepine receptors in vitro with a K_i of ~1470 nM^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

3-Hydroxymethyl-β-carboline (5-25 mg/kg; intravenous injection; single administration) acts as an active antagonist against Flurazepam-induced cerebrovascular and cerebral metabolic inhibition in rats. At a dose of 5 mg/kg, it reverses the aforementioned effects of 5 mg/kg Flurazepam; whereas administration of 25 mg/kg of this compound alone stimulates cortical and subcortical cerebral blood flow (CBF) as well as cortical cerebral metabolic rate of oxygen (CMRO₂)^[1].
3-Hydroxymethyl-β-carboline (2-100 mg/kg; i.p.; single administration) acts as a benzodiazepine antagonist, which significantly reduces the anticonvulsant protective effect of Diazepam on Mus musculus (reduced to 10% at 25 mg/kg) and the exploratory behavior induced by anxiolysis (reduced to 32.5 shuttles at 25 mg/kg), while high doses decrease spontaneous locomotor activity^[2].
Single administration of 3-Hydroxymethyl-β-carboline (20 mg/kg) has no effect on sodium-dependent high-affinity choline uptake in cortical or hippocampal synaptosomes of rats, and does not induce obvious behavioral changes^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Sprague-Dawley (male, 7 months old, anesthetized with 70% N₂O/30% O₂)^[1]
Dosage:

5 mg/kg (reversal of 5 mg/kg flurazepam); 25 mg/kg (reversal of 5 and 50 mg/kg flurazepam, standalone stimulation)
Administration:

i.v.; single dose; administered 5 minutes after flurazepam or vehicle
Result:

Showed no significant increase in cortical or subcortical CBF or cortical CMRO₂ compared to control when given alone at 5 mg/kg.
Reversed flurazepam (5 mg/kg)-induced decreases in right cortical CBF from 79 to 96 mL/100g per min, left cortical CBF from 80 to 93 mL/100g per min, right subcortical CBF from 60 to 72 mL/100g per min, left subcortical CBF from 63 to 74 mL/100g per min, and cortical CMRO₂ from 5.43 to 7.12 mL O₂/100g per min at 5 mg/kg.
Had little effect on flurazepam (50 mg/kg)-induced decreases in CBF and CMRO₂ at 5 mg/kg.
Produced a significant increase in cortical and subcortical CBF and cortical CMRO₂ compared to control when given alone at 25 mg/kg.
Reversed flurazepam (5 mg/kg)-induced decreases in CBF and CMRO₂ at 25 mg/kg.
Reversed flurazepam (50 mg/kg)-induced decreases in CBF and CMRO₂ at 25 mg/kg.
Failed to effectively reverse flurazepam-induced decreases in blood pressure and heart rate at both doses.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
