The antiplasmodial activity of a series of spirotetrahydro β-carbolines is described. Racemic spiroazepineindole (1) was identified from a phenotypic screen on wild type Plasmodium falciparum with an in vitro IC50 of 90 nM. Structure-activity relationships for the optimization of 1 to compound 20a (IC50 = 0.2 nM) including the identification of the active 1R,3S enantiomer and elimination of metabolic liabilities is presented. Improvement of the pharmacokinetic profile of the series translated to exceptional oral efficacy in the P. berghei infected malaria mouse model where full cure was achieved in four of five mice with three daily doses of 30 mg/kg.

1-Phenoxy-3-(3-indolyl)-tert.-butyl!amino-2-propanols and related 1-aryloxy compounds are antihypertensive agents having vasodilator and adrenergic β-receptor blocking action. Preferred compounds bear an ortho-substituent in the phenoxy group, and most preferably the cyano group.
