Two new abietane diterpenoid glucosides, talienosides A and B ( and ), along with four known compounds (-), were isolated from the ethyl acetate soluble portion of 70% acetone extract of the underground parts of . Their structures were elucidated based on the analyses of extensive spectroscopic data and physicochemical properties. The two new compounds were tested for their bioactivities against malaria and diabetes by β-hematin formation inhibition and α-glycosidase inhibition experiments, respectively. However, only showed weak β-hematin formation inhibitory activity. [Formula: see text].

A series of novel carnosic acid derivatives incorporating urea moieties at the C-20 position was synthesized and evaluated for their antiproliferative activity against the HCT116 colorectal cancer cell line. Most derivatives demonstrated enhanced antiproliferative activity compared to that of carnosic acid . The most promising derivatives were tested in other colorectal cancer cell lines (SW480, SW620, and Caco-2), melanoma (A375), and pancreatic cancer (MiaPaca-2).

Considering the detrimental impacts of the current pesticides on the biotic components of the biosphere, the development of novel pesticides is vital. Plant-derived biopesticides have emerged as popular alternatives to create a safer and more sustainable agriculture model. This study aims to validate the previous bioguided fractionation of endemic Canary Islands sage, , as a potential source of botanical pesticides using a cultivation process.

Septic shock involves severe systemic inflammatory reaction toward various invading species, such as microorganisms and microbial toxins. Such a response is complicated and characterized as being a dynamic and time-dependent phenomenon. During this response, a significant amount of pro-inflammatory cytokines may be produced, causing a rapid death rate in septic victims and occasionally leading to apoptosis of immune cells within the first hours of septic reaction.
