A negative electrode for a secondary battery includes a current collector and a negative electrode active material layer provided on at least one surface of the current collector. The negative electrode active material layer includes a first region corresponding to 50% of a total thickness of the negative electrode active material layer from a surface facing the current collector and a second region corresponding to 50% of the total thickness of the negative electrode active material layer from a surface opposite to the surface facing the current collector. The negative electrode active material layer includes two or more types of negative electrode active materials having D50 different from each other and satisfies the Equations 1 and 2. A secondary battery including the negative electrode is also provided.

Novel cis-epoxide compounds of formula (I) are useful for treating or preventing diseases caused by HIV infection: ##STR1## wherein A, B, R.sub.1 to R.sub.4 and n have the same meanings as defined in the specification. The novel HIV protease inhibitor of the formula (I) has a specific structure to form a stable bonding with the enzyme active site, which entails a highly enhanced irreversible inhibition against HIV protease.
