The present invention provides methods for treating Pneumocystis carinii pneumonia, Giardia lamblia, and Cryptosporidium parvum in a subject in need of such treatment. The methods comprise adminstering to the subject a compound of Formula (I): ##STR1## wherein: R.sub.1 and R.sub.2 are each independently selected from the group consisting of H, loweralkyl, aryl, alkylaryl, aminoalkyl, aminoaryl, halogen, oxyalkyl, oxyaryl, or oxyarylalkyl; R.sub.3 and R.sub.4 are each independently selected from the group consisting of H, loweralkyl, oxyalkyl, alkylaryl, aryl, oxyaryl, aminoalkyl, aminoaryl, or halogen; and X and Y are located in the para or meta positions and are selected from the group consisting of H, loweralkyl, oxyalkyl, and ##STR2## wherein: each R.sub.5 is independently selected from the group consisting of H, loweralkyl, alkoxyalkyl, hydroxyalkyl, aminoalkyl, alkylaminoalkyl, cycloalkyl, aryl, or alkylaryl or two R.sub.5 groups together represent C.sub.2 -C.sub.10 alkyl, hydroxyalkyl, or alkylene; and R.sub.6 is H, hydroxy, loweralkyl, alkoxyalkyl, hydroxyalkyl, aminoalkyl, alkylamino, alkylaminoalkyl, cycloalkyl, hydroxycycloalkyl, alkoxycycloalkyl, aryl, or alkylaryl; or a phamaceutically acceptable salt thereof. The compounds ar administered in an amount effective to treat the condition. The present invention also includes novel compounds useful in the treatment of Pneumocystis carinii pneumonia, Giardia lamblia, and Cryptosporidium parvum.
