ABSTRACT:
A compound having HIV Integrase Inhibitory activity of the formula:(wherein:R1is optionally substituted aralkyl;R2and R3are each independently hydrogen, optionally substituted alkyl, optionally substituted amino, optionally substituted alkenyl or optionally substituted alkoxy (provided that each substituent for “optionally substituted” is a noncyclic group);R4is hydrogen, optionally substituted carboxy, optionally substituted formylamino, optionally substituted carbamoyl, optionally substituted amino (provided that a substituent on amino in “optionally substituted formylamino”, “optionally substituted carbamoyl” and “optionally substituted amino” may form an optionally-substituted N-atom containing heterocyclic ring together with an adjacent N atom), optionally substituted alkyl, optionally substituted alkenyl, optionally substituted aryl, or optionally substituted heteroaryl) or a salt thereof.
