To develop new potential pesticide candidates from low value-added natural bioactive products, a series of new cholesterol–matrine conjugates (I(a–e)–IV(a–e)) were prepared from two lead compounds cholesterol and matrine. Against Mythimna separata Walker, compound IVa exhibited 3.0 and 2.6 folds promising insecticidal activity of cholesterol and matrine, respectively; against Aphis citricola Van der Goot, compound IVd showed 4.3 and 2.2 folds potent aphicidal activity of their precursors; notably, it also showed good control effects in the greenhouse; against Plutella xylostella Linnaeus at a dose of 20 μg/nymph, compound IIIe exhibited 2.8 and 2.0 folds oral toxicity of cholesterol and matrine, respectively. Compounds IIIe, IVd and IVe can be used as the leads for further structural optimization as the insecticidal and aphicidal agents.

In continuation of our program aimed at the development of natural product-based pesticidal agents, a series of matrinic amide derivatives containing 1,3,4-thiadiazole scaffold were prepared, and their insecticidal and acaricidal activities were evaluated against Mythimna separata and Tetranychus cinnabarinus. Some compounds exhibited potent insecticidal and acaricidal activities. It suggested that R1 as a nitro group and R2 as a fluorine atom, were important for the insecticidal activity; R1 as the electron-donating groups and R2 as the methyl group, were necessary for the acaricidal activity.

To discover new natural-product-based potential pesticides, 85 matrinic acid/alcohol/ester derivatives were synthesized by structural modifications of a quinolizidine alkaloid matrine. N-(4-Methyl)benzylmatrinyl n-decylate (76) and N-(2-chloro)benzylmatri
