An additive for a non-aqueous electrolyte solution that can suppress the initial gas generation amount when used in a non-aqueous electrolyte solution battery. The additive for a non-aqueous electrolyte solution is represented by any one of formulae [1] to [4]: ##STR00001## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, X.sup.1, X.sup.2 and Y are as defined in the specification.

The present invention discloses compounds of Formula (I), or pharmaceutically acceptable salts, esters, or prodrugs thereof:
X-A-Y-L-R  (I)
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.
