7-Deaza-2'-C-methyladenosine Usage And Synthesis

Uses

7-Deaza-2''-C-methyladenosine is a hepatitis C virus (HCV) polymerase inhibitor.

Definition

MK 0608 (7-Deaza-2'-C-methyladenosine) is an anti-viral agent against Hepatitis C Virus (HCV). It has been shown to inhibit viral RNA replication in the subgenomic HCV genotype 1b replicon, with a 50% effective concentration (EC50) of 0.3 μM (EC90 = 1.3 μM). To determine efficacy in vivo, MK-0608 was administered to HCV-infected chimpanzees, resulting in dose- and time-dependent decreases in plasma viral loads. In separate experiments, chimpanzees dosed for 7 days with MK-0608 at 0.2 and 2 mg per kg of body weight per day by intravenous administration experienced average reductions in viral load of 1.0 and >5 log10 IU/ml, respectively.

in vivo

Oral dosing of MK-0608 results in a potent antiviral effect. In preclinical pharmacokinetic experiments with rats, dogs, and rhesus monkeys, MK-0608 demonstrates good to excellent oral bioavailability (50 to 100%) and long plasma half-lives in dogs and rhesus macaques (9 and 14 h, respectively)^[1].

• Animal Model: The HCV-infected chimpanzees^[1]
• Dosage: 1 mg/kg
• Administration: Administered orally; once daily for 37 days
• Result: Chimpanzee X6 had a baseline viral load that varied from 1,110 to 12,900 IU/mL, and chimpanzee X4 had a baseline viral load of 3×10⁶ to 9×10⁶ IU/mL.

Solubility in organics

Soluble in DMSO, not in water.

storage

Dry, dark and at 0 - 4℃ for short term (days to weeks) or -20 ℃ for long term (months to years).
