Description

Denzimol hydrochloride is an orally active anticonvulsant agent. Denzimol hydrochloride inhibits cytochrome P450, and interacts with benzodiazepine receptors. Denzimol hydrochloride selectively antagonizes tonic components of Metrazol-induced seizures in rats and mice. Denzimol hydrochloride can be used for the research of epilepsy and convulsions[1][2][3][4][5][6].

In Vitro

Denzimol hydrochloride binds reversibly to rat liver microsomal cytochrome P450 as a type II ligand with a Ks value of 6.66 mM[1].
Denzimol (10-10-10-4 M; 20 min) hydrochloride inhibits rat liver microsomal Carbamazepine (HY-B0246) 10,11-epoxidation, Diazepam C3-hydroxylation, and Diazepam N1-dealkylation with IC50 values of 4.26 × 10-7 M, 1.44 × 10-6 M, and 6.66 × 10-7 M, respectively[1].
Denzimol hydrochloride does not alter the plasma protein binding of diazepam in pooled rat serum in vitro[2].

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

In Vivo

Denzimol (0.94-15 mg/kg; p.o.; single dose) hydrochloride inhibits hepatic drug metabolism in rats[1].
Denzimol (5 mg/kg; p.o.; single dose; 15 minutes prior to Diazepam injection) hydrochloride significantly increases diazepam plasma and brain concentrations in rats by reducing diazepam's total plasma clearance by ~40%, resulting in an 1.8-fold higher plasma AUC0-t and doubled brain diazepam concentrations[2].
Denzimol (up to 289 mg/kg; i.p.; single dose) hydrochloride selectively antagonizes tonic components of Metrazol-induced seizures in rats, with an ED50 of 2.02 mg/kg for protection against tonic hindpaw extension, and shows no activity against clonic seizures at doses up to 260 mg/kg[4].
Denzimol (up to 182 mg/kg; p.o.; single dose) hydrochloride selectively antagonizes tonic components of Metrazol-induced seizures in mice, with an ED50 of 8.8 mg/kg for protection against tonic hindpaw extension, and shows no activity against clonic seizures at doses up to 182 mg/kg[4].

Animal Model: CD-COBS rats (male, 200-300 g)[1]
Dosage: 15 mg/kg (CBZ disposition study); 0.94, 1.87, 3.75, 7.50, 15.0 mg/kg (pentobarbitone sleeping time study)
Administration: p.o.; single dose; 30 minutes before CBZ injection (CBZ disposition study); p.o.; single dose; 1 hour before pentobarbitone injection (pentobarbitone sleeping time study)
Result: Reduced CBZ total plasma clearance from 15.3 mL/min/kg to 9.9 mL/min/kg.
Prolonged CBZ elimination half-life from 83 minutes to 134 minutes.
Caused non-significant increase in CBZ-E elimination half-life from 184 minutes to 240 minutes.
Caused non-significant reductions in CBZ-E peak plasma concentrations from 14 nmol/mL to 11 nmol/mL and time to maximum CBZ-E concentrations from 132 minutes to 202 minutes.
Prolonged pentobarbitone sleeping time.
Achieved an ED50 of 3.0 mg/kg for doubling or more of control sleeping time.
Animal Model: CD-COBS (male, 270-300 g)[2] 5 mg/kg
Dosage: 5 mg/kg
Administration: p.o.; single dose; 15 minutes prior to diazepam injection
Result: Increased plasma diazepam concentrations throughout the 180-minute sampling period, resulting in a 1.8-fold increase in plasma area under the curve (AUC).
Reduced total plasma clearance of diazepam by ~40%.
Doubled diazepam brain concentrations compared to controls at both 60 minutes and 180 minutes.
Had no significant effect on diazepam's apparent volume of distribution, elimination half-life, or plasma protein binding.
Animal Model: Sprague-Dawley (female, 110-130 g, maximal metrazol/PTZ-induced seizures model)[4]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
