From the roots of the African plant Bulbine frutescens (Asphodelaceae), two unprecedented novel dimeric phenylanthraquinones, named joziknipholones A and B, possessing axial and centrochirality, were
Synthesis and pharmacological evaluation of fluorescent and photoactivatable analogues of antiplasmodial naphthylisoquinolines (Publications)
The naphthylisoquinoline (NIQ) alkaloids from tropical Ancistrocladaceae and Dioncophyllaceae plants show high antiplasmodial activities in vitro and in vivo, even against chloroquine-resistant strain

The isolation and structural elucidation of dioncophylline E, a novel naphthylisoquinoline alkaloid from the rare West African liana Dioncophyllum thollonii, is described. The alkaloid displays an unu
Low serum DHEA-S is associated with impaired lung function in women (Publications)
Background: Emerging evidence suggests that androgens and estrogens have a role in respiratory health, but it is largely unknown whether levels of these hormones can affect lung function in adults fro
Regular physical activity levels and incidence of restrictive spirometry pattern: a longitudinal analysis of two population-based cohorts (Publications)
A restrictive spirometry pattern is associated with high morbidity and mortality. Whether practicing regular physical activity protects against this pattern has never been studied. We estimated the as
