Biological Activity

Description Ritonavir is an antiretroviral (HIV) drug and inhibitor of particular liver enzyme that normally metabolizes protease inhibitors, cytochrome P450-3A4 (CYP3A4).
Targets HIV Protease          
IC50            

Protocol

Anti-virus experiment [1]:

Viruses

HIV

Preparation method

The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months.

Reacting condition

0 ~ 0.16 μM

Applications

Ritonavir potently inhibited the activity of laboratory and clinical strains of HIV-1 with the EC50 values ranging from 0.022 to 0.13 μM. Moreover, Ritonavir also efficiently inhibited the activity of HIV-2, with the EC50 value of 0.16 μM.

Animal experiment [1]:

Animal models

Male SD rats

Dosage form

10 mg/kg; p.o.

Applications

In rats, oral administration of 10 mg/kg Ritonavir resulted in prolonged absorption (tmax = 2.0 hrs). The peak of plasma Ritonavir concentration was > 100 folds of the EC50 value. The calculated oral bioavailability reached 78%.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

Ritonavir, previously known as ABT-538, is a potent inhibitor of human immunodeficiency virus type 1 (HIV-1) protease that exhibits potent in vitro inhibition against HIV-1 strain as well as HIV-2 strain with 50% effective concentration EC50 values of 0.022 μM and 0.16 μM respectively. Ritonavir binds to the HIV-1 protease inactivating its function to cleave the Gag and Gag-Pol polyproteins into the core proteins and viral enzymes, which results in the formation of noninfectious viral particles. X-ray crystallographic analysis reveals a hydrophobic cluster between the isopropyl substituent on the P3 thiazolyl group of ritonavir and the side chains of Pro-81 and Val-82 of HIV-1 protease within the complex of ritonavir/HIV-1 protease.
