Ritonavir (previously known as ABT-538; A-84538; RTV; ABT538, trade name: Norvir) is a L-valine derivative and potent inhibitor of HIV-1 protease used to treat HIV infection and AIDS. It is widely used as a booster for other protease inhibitors/PIs such as lopinavir, and makes them work better. More specifically, ritonavir is used to inhibit a particular liver enzyme that normally metabolizes protease inhibitors, CYP3A4. Ritonavir 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.

实验参考方法

In Vitro	In vitro activity: Ritonavir is a very potent inhibitor of CYP3A4 mediated testosterone 6β-hydroxylation with mean Ki of 19 nM and also inhibits tolbutamide hydroxylation with IC50 of 4.2 μM. Ritonavir is found to be a potent inhibitor of CYP3A-mediated biotransformations (nifedipine oxidation with IC50 of 0.07 mM, 17alpha-ethynylestradiol 2-hydroxylation with IC50 of 2 mM; terfenadine hydroxylation with IC50 of 0.14 mM). Ritonavir is also found to be an inhibitor of the reactions mediated by CYP2D6 (IC50 = 2.5 mM) and CYP2C9/10 (IC50 = 8.0 mM). Ritonavir results in an increase in cell viability in uninfected human PBMC cultures. Ritonavir markedly decreases the susceptibility of PBMCs to apoptosis correlated with lower levels of caspase-1 expression, decreases in annexin V staining, and reduces caspase-3 activity in uninfected human PBMC cultures. Ritonavir inhibits induction of tumor necrosis factor (TNF) production by PBMCs and monocytes in a time- and dose-dependent manner at nontoxic concentrations. Ritonavir inhibits p-glycoprotein-mediated extrusion of saquinavir with an IC50 of 0.2 μM, indicating a high affinity of ritonavir for p-glycoprotein. Ritonavir inhibits human liver microsomal metabolism of ABT-378 potently with Ki of 13 nM. Ritonavir combined with ABT-378 (at 3:1 and 29:1 ratios) inhibits CYP3A (IC50 = 1.1 and 4.6 μM), albeit less potently than Ritonavir (IC50 = 0.14 μM).
