Phytochemical investigation of the figs of Ficus mucuso led to the isolation of three new isoflavone dimer derivatives, mucusisoflavones A-C (1-3), together with 16 known compounds. Some of the isolates were tested in vitro for their inhibitory properties toward β-glucuronidase and Plasmodium falciparum enoyl-ACP reductase (PfENR) enzymes. Compound 1 (IC₅₀) 0.68 μM) showed inhibitory activity on β-glucuronidase enzyme, while 3 (IC₅₀) 7.69 μM) exhibited a weak inhibitory activity against P. falciparum enoyl-ACP reductase (PfENR).
Action sites of low positive temperature together with high light intensities in electron transport reactions of photosystem II (PSII) evaluated by ms range delayed fluorescence (ms-DLE) of chlorophyll a content in the maize and barley seedlings are presented. The main targets for these stress factors action were shown to be Yz and Mn4OxCa-cluster on the donor site of PSII in the case of simultaneous action of different temperatures and high light illumination and between QA and QB on the acceptor site of PSII in the case of low positive temperature influence only.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
