The development of direct-acting antiviral agents is a promising therapeutic advance in the treatment of hepatitis C virus (HCV) infection. However, rapid emergence of drug resistance can limit efficacy and lead to cross-resistance among members of the same drug class. ABT-450 is an efficacious inhibitor of HCV NS3/4A protease, with 50% effective… (More)
Through broad screening of the compound library at Pharmacia, a naphthalene carboxamide was identified as a nonnucleoside inhibitor of human cytomegalovirus (HCMV) polymerase. Structure-activity relationship studies demonstrated that a quinoline ring could be substituted for naphthalene, resulting in the discovery of a 4-hydroxyquinoline-3-carboxamide… (More)
UNLABELLED Poly(ADP-ribose) polymerases (PARP1, -2, and -3) play important roles in DNA damage repair. As such, a number of PARP inhibitors are undergoing clinical development as anticancer therapies, particularly in tumors with DNA repair deficits and in combination with DNA-damaging agents. Preclinical evidence indicates that PARP inhibitors potentiate… (More)
We identified a novel class of 4-oxo-dihydroquinolines represented by PNU-183792 which specifically inhibit herpesvirus polymerases. PNU-183792 was highly active against human cytomegalovirus (HCMV, IC(50) value 0.69 microM), varicella zoster virus (VZV, IC(50) value 0.37 microM) and herpes simplex virus (HSV, IC(50) value 0.58 microM) polymerases but was… (More)
A novel series of 4-oxo-4,7-dihydrothieno[2,3-b]pyridine-5-carboxamides have been identified as potential antivirals against human herpesvirus infections resulting from human cytomegalovirus (HCMV), herpes simplex virus type 1 (HSV-1), and varicella-zoster virus (VZV). Compounds 10c and 14 demonstrated broad-spectrum inhibition of the herpesvirus… (More)
The 4-oxo-dihydroquinolines (PNU-182171 and PNU-183792) are nonnucleoside inhibitors of herpesvirus polymerases (R. J. Brideau et al., Antiviral Res. 54:19-28, 2002; N. L. Oien et al., Antimicrob. Agents Chemother. 46:724-730, 2002). In cell culture these compounds inhibit herpes simplex virus type 1 (HSV-1), HSV-2, human cytomegalovirus (HCMV),… (More)
A novel series of 2-aryl-2-hydroxyethylamine substituted 4-oxo-4,7-dihydrothieno[2,3-b]pyridine-5-carboxamides have been identified as potent antivirals against human herpesviruses. These compounds demonstrate broad-spectrum inhibition of the herpesvirus polymerases HCMV, HSV-1, EBV, and VZV with high specificity compared to human DNA polymerases.
Discovery efforts were focused on identifying a non-nucleoside antiviral for treating infections caused by human cytomegalovirus (HCMV) with equal or better potency and diminished toxicity compared to current therapeutics. This Letter describes the HCMV DNA polymerase inhibition and in vitro antiviral activity of various 2-aryl-2-hydroxy ethylamine… (More)
A series of C-2 pyrroloquinoline analogs designed to improve aqueous solubility were examined for herpesvirus polymerase and antiviral activity. Several analogs were identified that maintained the antiviral activity of the previous development candidate against HCMV, HSV-1 and VZV, but with significantly improved aqueous solubility.
A versatile synthesis of 4-oxo-4,7-dihydrofuro[2,3-b]pyridine-5-carboxylate esters has been developed which has lead to the identification of a new series of non-nucleoside inhibitors of human herpesvirus polymerases HCMV, HSV-1, EBV, and VZV with high specificity compared to human DNA polymerases.
