Abstract
Plant-derived natural products are important resources for pesticide discovery. Acetylcholinesterase (AChE) is a well-validated pesticide target, and inhibiting AChE proves fatal for insects. Recent studies have shown that the potential of various sesquiterpenoids as AChE inhibitors. However, few studies have been conducted with eudesmane-type sesquiterpenes with AChE inhibitory effects. Therefore, in this research, we isolated two new sesquiterpenes, laggeranines A (1) and B (2), along with six known eudesmane-type sesquiterpenes (3-8) from Laggera pterodonta, and characterized their structures and the inhibitory effect they exerted on AChE. The results showed that these compounds had certain inhibitory effects on AChE in a dose-dependent manner, of which compound 5 had the best inhibitory effect with IC50 of 437.33 ± 8.33 mM. As revealed by the Lineweaver-Burk and Dixon plots, compound 5 was observed to suppress AChE activity reversibly and competitively. Furthermore, all compounds exhibited certain toxicity levels on C. elegans. Meanwhile, these compounds had good ADMET properties. These results are significant for the discovery of new AChE targeting compounds, and also enrich the bioactivity activity repertoire of L. pterodonta.

Abstract
Around 3000 species of Saussurea are known, however Saussurea lappa Clarke
which is perennial herb and has been traditionally used as anticancer, anti-inflammatory,
antiviral, medicine without many adverse effects. Phytochemistry of Saussurea lappa after
thorough literature survey revealed various varied and copious metabolites such as sesquiterpenes,
flavonoids, phytosterols, lignans, terpenes. Many of these compounds have been
found to possess a wide range of biological activity such as anticancer, anti-inflammatory,
anti-hepatotoxic, anti-viral, etc. Among sesquiterpenes particularly Dehydrocostuslactone,
dihydrocostunolide, costunolide Lappadilactone, have been isolated as the main chemical
constituents. This review aims to cover published work from public databases (e.g. PubMed,
Google Scholar, ResearchGate) and Non-English, Ph.D./MS thesis databases (e.g. CKNIChina,
Jairo-Japan, Myto-Malaysia, Shodhganga-India) with a particular focus on
phytochemistry and therapeutic uses of different fractions as well as isolated compounds
from Saussurea lappa.
