* IC50 is the concentration for 50% inhibition of the specified step of integrase activity. EC50 is the concentration for 50% inhibition of virus replication. EC95 is the concentration for 95% inhibition of virus replication. CC50 is the concentration to reduce cell viability by 50%. CC95 is the concentration to reduce cell viability by 95%. TI (therapeutic index) is the ratio of CC50 to EC50.
