Hepatitis B, a viral infectious disease caused by hepatitis B virus (HBV), is a life-threatening disease that leads liver cirrhosis and liver cancer. Because the current treatments for HBV, such as an interferon (IFN) formulation or nucleoside/nucleotide analogues, are not sufficient, the development of a more effective agent for HBV is urgent required. CDM-3008 (1, 2-(2,4-bis(trifluoromethyl)imidazo[1,2-alpha][1,8]naphthyridin-8-yl)-1,3,4-oxadiazole) (RO8191)) is a small molecule with an imidazo[1,2-alpha][1,8] naphthyridine scaffold that shows anti-HCV activity with an IFN-like effect. Here, we report that 1 was also effective for HBV, although the solubility and metabolic stability were insufficient for clinical use. Through the structure-activity relationship (SAR), we discovered that CDM-3032 (11, N-(piperidine-4-yl)-2,4-bis(trifluoromethyl)imidazo[1,2-alpha][1,8]naphthyridine-8-carboxamide hydrochloride) was more soluble than 1 (> 30 mg/mL for 11 versus 0.92 mg/mL for 1). In addition, the half-life period of 11 was dramatically improved in both mouse and human hepatic microsomes (T1/2,> 120 min versus 58.2 min in mouse, and > 120 min versus 34.1 min in human, for 11 and 1, respectively).

The microwave-enhanced synthesis of 2-chloro-3-formylbenzo[1,8]naphthyridines 3a-c has been achieved rapidly in good yield via the Vilsmeier-Haack cyclisation of N-(4-methylquinolin-2yl) acetamide 2a-d. The precursors N-(4-methylquinolin-2-yl) acetamide derivatives were effectively prepared in a single step from 2-aminoquinoline and acetic anhydride in presence of Amberlite-120A cation exchange catalyst under microwave irradiation. Condensation of 3a-d, with thioglycolic acid under microwave irradiation using anhydrous potassium carbonate as catalyst afforded thieno[2,3-b]benzo[1,8]naphthyridine-2-carboxylic acids (TBNCS) 4a-g. Elemental analysis, IR, H-1 NMR, and mass spectral studies were used to characterize these compounds. The interaction of thieno[2,3-b] benzo[1,8]naphthyridine-2-carboxylic acid (TBNC)(4a) with CT-DNA was studied by UV-Vis, viscosity as well as thermal denaturation methods. On binding to DNA, the absorption spectrum underwent bathochromic and hypochromic shifts. Binding parameters, determined from spectrophotometeric measurements indicated a binding constant of 1.8 X 10(6) M-1. The thieno[2,3-b]benzo[1,8] naphthyridine-2-carboxylic acid (4a) increases the viscosity of sonicated rod- like DNA fragments. The binding of TBNC to DNA increased the melting temperature by about 4 degrees C. DNA interaction studies suggest that (4a) binds to calf thymus DNA (CT-DNA).
