Abstract:
The present invention discloses compounds of Formula (I), or pharmaceutically acceptable salts, thereof: which inhibit the protein(s) encoded by hepatitis B virus (HBV) or interfere with the function of the HBV life cycle of the hepatitis B virus and are also useful as antiviral agents. The present invention further relates to pharmaceutical compositions comprising the aforementioned compounds for administration to a subject suffering from HBV infection. The invention also relates to methods of treating an HBV infection in a subject by administering a pharmaceutical composition comprising the compounds of the present invention.

Claim (Index 7):
The compound of  claim 1 , represented by Formula (IIa-3) or (IIb-3), or a pharmaceutically acceptable salt thereof, wherein A 1  is a 5-membered heteroaryl group containing 1 to 4 heteroatoms selected from O, N, and S; A 2  is an optionally substituted phenyl, thiophenyl or 6-membered heteroaryl group including but not limited to pyridinyl, pyrazinyl, or pyrimidinyl; X 1  is optionally substituted methyl, halo, CN, OR 11 , or NR 11 R 12 ; v is 0, 1, 2, 3, or 4; E at each occurrence is same or different and independently selected from \u2014CR 15 R 16 \u2014, \u2014C(O)\u2014, \u2014O\u2014, \u2014NR 16 \u2014, \u2014S\u2014, and \u2014S(O) 2 \u2014; u is 0, 1, 2, or 3; R 15  is hydrogen, halo, CN, \u2014NR 11 R 12 , optionally substituted \u2014C 1 -C 8  alkyl, optionally substituted \u2014C 2 -C 8  alkenyl, optionally substituted \u2014C 2 -C 8  alkynyl, optionally substituted \u2014C 3 -C 8  cycloalkyl, optionally substituted 3- to 8-membered heterocyclic, optionally substituted aryl and optionally substituted heteroaryl; R 16  is hydrogen, optionally substituted \u2014C 1 -C 8  alkyl, optionally substituted \u2014C 2 -C 8  alkenyl, optionally substituted \u2014C 2 -C 8  alkynyl, optionally substituted \u2014C 3 -C 8  cycloalkyl, optionally substituted 3- to 8-membered heterocyclic, optionally substituted aryl and optionally substituted heteroaryl; alternatively, R 15  and R 16  are taken together with the carbon atom to which they are attached to form an optionally substituted C 3 -C 7  cycloalkyl or an optionally substituted 3- to 7-membered heterocyclic; Y and Z are as defined in  claim 1 .
