Biological Activity
Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1].
Ritonavir (ABT 538) is an inhibitor of CYP3A4 mediated testosterone 6β-hydroxylation with mean Ki of 19 nM and also inhibits tolbutamide hydroxylation with IC50 of 4.2 μM[2].
Ritonavir (ABT 538) 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 an inhibitor of the reactions mediated by CYP2D6 (IC50=2.5 mM) and CYP2C9/10 (IC50=8.0 mM)[3].
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[4].
Ritonavir inhibits p-glycoprotein-mediated extrusion of saquinavir with an IC50 of 0.2 μM, indicating a high affinity of ritonavir for p-glycoprotein[5].
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)[6].
