Chemical Diversity and Biosynthesis of Drimane‐Type Sesquiterpenes in the Fungal Kingdom
ChemBioChem, Volume 23, Issue 17, September 5, 2022., 2022 Fungal drimane‐type sesquiterpenes (DTSs) are emerging as a very interesting class of chemicals with many notable activities. Elucidation of DTS biosynthesis in fungi revealed that the two main precursors, drimenol and drim‐8‐ene‐11‐ol, are the preferred backbones.

Evidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022 Introduction. The Uganda National Drug Authority requires phytochemical screening, freedom from microbial contamination, and evidence of safety and efficacy of the constituent plants to register herbal products. Since Uganda has no pharmacopeia, safety, efficacy, and plant processing information are not readily available.

Effect of Polygodial on the Mitochondrial ATPase of Saccharomyces cerevisiae [PDF]
Antimicrobial Agents and Chemotherapy, 2000 ABSTRACT The fungicidal mechanism of a naturally occurring sesquiterpene dialdehyde, polygodial, was investigated in Saccharomyces cerevisiae . In an acidification assay, polygodial completely suppressed the glucose-induced decrease in external pH at 3.13 μg/ml, the same as the fungicidal concentration ...

Anthelmintic Agents from African Medicinal Plants: Review and Prospects
Evidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022 Soil‐transmitted helminthiasis affects more than 1.5 billion people globally and largely remains a sanitary problem in Africa. These infections place a huge economic burden on poor countries and affect livestock production, causing substantial economic losses and poor animal health. The emergence of anthelmintic resistance, especially in livestock, and
