Abstract
Unlike its mammalian hosts, the opportunistic fungal pathogen Pneumocystis carinii harbors group I self-splicing introns in its chromosomal genes encoding rRNA. This difference between pathogen and host suggests that intron splicing is a promising target for chemotherapy. We have found that intron splicing in vitro is inhibited by the anti-Pneumocystis agent pentamidine and by a series of pentamidine analogues, as well as by some aminoglycosides, tetracycline, L-arginine and ethidium bromide. Further studies will be needed to determine if this is the mechanism of action of pentamidine against P. carinii.Keywords
