The screening and testing of extracts against a variety of pharmacological targets in order to
benefit from the immense natural chemical diversity is a concern in many laboratories …

Background Malaria remains a significant public health challenge in regions of the world
where it is endemic. An unprecedented decline in malaria incidences was recorded during …

The present volume is the third in a trilogy that documents naturally occurring
organohalogen compounds, bringing the total number—from fewer than 25 in 1968—to …

Four new polyketides, penitalarins A–C (1–3) and nafuredin B (4), together with the known
biogenetically related nafuredin A (5) were isolated from a mixed culture of a deep-sea …

Six undescribed compounds, uvarirufols D and E,(+)-uvarigranol B,(−)-uvarigranol E, 6-
acetoxy-5-hydroxy-7-methoxyflavanone and cherrevenaphthalene D, along with twelve …

The previous two surveys documented a combined total of 4714 naturally occurring
organohalogen compounds, both biogenic and abiotic [1, 2]. In the subsequent two …

Last year more than 200 naturally occurring organohalogens were described for the first
time. These natural products were isolated and characterized from marine algae, sponges …

Abstract An intramolecular benzyne–phenolate [4+ 2] cycloaddition is reported. Benzyne
precursors, having vicinal halogen‐sulfonate functionalities, linked with a phenol (ate) by …

Three new oxygenated cyclohexene derivatives, trichocarpeols A (1), B (2), and C (3), along
with nine known secondary metabolites, were isolated from the methanolic root extract of …

The chemical study of leaf extracts from Uvaria cherrevensis resulted in the identification of
11 new polyoxygenated cyclohexenes, cherrevenols A–K (1–11), and a new seco …
