13-Oxo-9E,11E-octadecadienoic acid, a potent PPARα activator derived from tomato juice and an isomer of 9-oxo-ODA, exhibits the ability to decrease plasma and hepatic triglyceride levels in obese diabetic mice[1].
13(S)-HpOTrE is a monohydroperoxy polyunsaturated fatty acid produced in soybeans by the action of soybean LO-2 on esterified α-linolenic acid.[1] Incubation of soybean seedling biomembranes with soybean LO-2 catalyzes the formation of both 9- and 13-HpOTrE in a molar ratio of 10:1.1 In plants, 13(S)-HpOTrE can be metabolized by the hydroperoxide lyase pathway producing aldehyde and oxoacid fragments, or by the hydroperoxide dehydratase pathway producing jasmonic acid.[2],[3],[4] Treatment of tomato leaves with 13-HpOTrE causes induction of proteinase inhibitors, simulating the normal response to wounding.5 This data suggests that in plants 13(S)-HpOTrE may participate in a lipid-based signalling system initiated by insect and pathogen attack.
Tomatine hydrochloride is an alkaloid that occurs in the extract of leaves of wild tomato plants. It inhibits the growth of many fungi and bacteria. It is used as a precipitating agent for steroids.
Strevertene A ((-)-Strevertene A) (Compound 1) 是一种五烯大环内酯的微生物次级代谢产物,作为抗生素,它展示了强效的抗真菌活性。Strevertene A 在抑制植物病原真菌如Alternaria mali、Aspergillus oryzae和Cylindrocarpon destructans的菌丝生长方面表现出显著效果,其IC50为4-16 μg/mL。此外,Strevertene A 对于控制番茄枯萎病的发展也有显著的抑制作用。
