A series of 1,3-bis(substituted phenoxy)-2-propanones, long-chain ketones, and relatedderivatives has been synthesized, and it has been found that certain analogues produce significant lowering of serum cholesterol levels in Sprague-Dawley rats. These compounds possess no estrogenic properties and are nontoxic at 10 mg/kg/day. Physical studies on these compounds include an attempt to correlate hypocholesteremic

We describe herein the antileishmanial activity of 1,3-bis(aryloxy)propan-2-amines, prepared in four simple steps from epichlorohydrin. Among the evaluated compounds, three (4o, 4q, and 4r) displayed considerable activity against Leishmania amazonensis promastigote forms, with IC50 values below 10 µM. We also analyzed the effects of the nature and the position of ring substituent on activity. Two amines

We describe herein the synthesis and antileishmanial activity of 1,3-bis(aryloxy)propan-2-ols. Five compounds (2, 3, 13, 17, and 18) exhibited an effective antileishmanial activity against stationary promastigote forms of Leishmania amazonensis (IC50 < 15.0 μm), and an influence of compound lipophilicity on activity was suggested. Most of the compounds were poorly selective, as they showed toxicity
