Based on the results mentioned below, the chemistry and biological activities of nematicidal compounds are discussed.

Table 1. Bioactive fungal products from endophytic fungi in recent literature reviews. The compounds include antifungal, antibacterial, antimycobacterial, antiviral, nematicidal, cytotoxic, antineoplastic, antioxidant, antiinsectant, antifeedant, antidiabetic, herbicidal, algicidal, specific en mie inhibitory, and immunomodulatory activities. 

The secondary metabolites of the endophytic fungi associated with dicotyledonous plants (dicots) are chemically diverse (Table 1). There is an equal diversity in the activities of these compounds, including antibacterial, antifungal, nematicidal, phytotoxic, cytotoxic, antineoplastic, anti-insectant, anti-herbivory, and a variety of other activities. The compounds isolated, structurally elucidated, and explored biologically in the short time since previous reviews continue to display that same wide array of chemical and biological diversity. 

Several nematicidal acetylenic compounds have been isolated. Most are from the Asteraceae (127). Recently isolated are (8R,9R, 10S)-9,10-epoxyheptadec-16-ene-4,6-diyne-8-ol and other compounds from Cirsium. iaponicum (128,129). 1-Phenylhepta-l,3,5-triyne and 2-phehyl-5-(1 -jjropynyl)-thiopene, from Coreopsis lanceolata and cis-dehydromatricaria ester from Soli dago altissima have been shown to be fly ovicidal substances (130,131).
