BMS-538203 is a highly efficient HIV integrase inhibitor and antiviral agent.IC50 value:Target: HIV integraseIn the current study we demonstrate a hit-to-clinical candidate pathway that resulted in 50- and 2000-fold improvements in enzyme-inhibition and antiviral activity without an increase in molecular weight or change in molecular topology. The original hit , 1 (mw = 268) was optimized in a stepwise manner. Potential covalent protein-binding moieties were removed by reducing the number of the ketone groups. High enzyme inhibition activity was achieved by optimizing the aryl-portion of the molecule. Protein binding was reduced by replacing the standard amide by the corresponding methyl-hydroxamide. This eventually led to the discovery of BMS-538203 compound 2 (mw = 269) a highly efficient inhibitor and antiviral agent.
NBD-557 is a potentially HIV-1 inhibitor.IC50 Value: Target: HIVNBD-557, is small molecule organic compounds with drug-like properties. It showed potent cell fusion and virus-cell fusion inhibitory activity at low micromolar levels. A systematic study showed that NBD-557 target viral entry by inhibiting the binding of HIV-1 envelope glycoprotein gp120 to the cellular receptor CD4 but did not inhibit reverse transcriptase, integrase, or protease, indicating that they do not target the later stages of the HIV-1 life cycle to inhibit HIV-1 infection. NBD-557 potent inhibitors of both X4 and R5 viruses tested in CXCR4 and CCR5 expressing cell lines, respectively, indicating that its anti-HIV-1 activity is not dependent on the coreceptor tropism of the virus. A surface plasmon resonance study, which measures binding affinity, clearly demonstrated that NBD-557 bind to unliganded HIV-1 gp120 but not to the cellular receptor CD4. NBD-557 was active against HIV-1 laboratory-adapted strains including an AZT-resistant strain and HIV-1 primary isolates, indicating that NBD-557 can potentially be further modified to become potent HIV-1 entry inhibitors.
Atazanavir sulfate is a sulfate salt form of atazanavir that is an highly potent HIV-1 protease inhibitor.Target: HIV-1 protease inhibitorAtazanavir sulfate is a sulfate salt form of atazanavir that is an highly potent HIV-1 protease inhibitor. It has a pharmacokinetic profile that supports once-daily dosing and has demonstrated a unique resistance profile and superior virologic potency compared with other antiretrovirals in vitro. In subjects with HIV, atazanavir (400 mg once daily) produced rapid and sustained improvements in viral load and CD4 counts in both antiretroviral-naive as well as previously treated patients when used in combination with dual nucleoside reverse transcriptase inhibitor (NRTI) treatment [1].After intravenous (iv), oral (po) and intraportal (ip) administration of ATV at a dosage of 7 mg/kg, AUCs in HL rats were 12.41, 5.24 and 8.89 microg/mLh, respectively, and were significantly higher than those in control rats (4.09, 1.70 and 3.38 microg/mLh). Despite the decrease of distribution volume (Vd(ss)), the terminal half-life (t(1/2)) in HL tended to be shorter than in control, and hepatic distribution of ATV in HL rats was 4.8-fold increases. These results suggested that the uptake of ATV into liver might counteract the decrease of Vd(ss). On the other hand, there was no significant difference in bioavailability, and the lymphatic transport to AUC showed no statistical change. In conclusion, although the protein binding rate and AUC were significantly increased, the pharmacokinetics of ATV might be tolerated in HL [2].Clinical indications: HIV-1 infection Toxicity: torsades de pointes
