Additions and Corrections 1997, Volume 40 Andre Rosowsky,* Andrew T. Papoulis, and Sherry F. Queener: 2,4-Diaminothieno[2,3-d]pyrimidine Lipophilic Antifolates as Inhibitors of Pneumocystis carinii and Toxoplasma gondii Dihydrofolate Reductase. Page 3696, Table 1. The IC50 value for PTX (4) against rat liver DHFR should read 0.0015 µM instead of 0.015 µM. The selectivity ratios for P. carinii and T. gondii relative to rat liver DHFR, however, were correctly calculated from the lower IC50 value. JM020059B 10.1021/jm020059b Published on Web 03/14/2002
