entomopathogenic

trans-Benzylideneacetone (Acetocinnamone) 是一种革兰氏阴性致病性线虫细菌嗜线虫(Xenorhabdus nematophila) 的代谢产物，是一种针对磷脂酶 A2 (PLA2) 的酶抑制剂，也是一种免疫抑制剂。

Isariin B is a new cyclodepsipeptide isolated from the entomopathogenic fungus Beauveria felina.

Hirsutide is a cyclotetrapeptide fungal metabolite produced by the entomopathogenic fungus Hirsutella. It has antibacterial activity against C. pyogenes, S. aureus, P. aeruginosa, and K. pneumonia (MICs = 25, 13, 6, and 21 μg/cm3, respectively). Hirsutide also has antifungal activity against C. albicans, M. audouinii, A. niger, and Ganoderma (MICs = 13, 6, 25, and 6 μg/cm3, respectively).

Sphingosine (d14:1) is a bioactive sphingolipid that has been found in B. mori (silkworm), P. clarkii (crayfish), and A. aurita (jellyfish) extracts. It increases the germination rate of N. rileyi, an entomopathogenic fungus, with an EC50 value of 10.2 nM. Sphingosine (d14:1) inhibits protein kinase C (PKC) in vitro (IC50 = 7.3 mol%) as well as superoxide generation induced by phorbol 12-myristate 13-acetate in neutrophils and reduces growth of CHO cells (IC50s = 19 and 8 μM, respectively).

Farinomalein A, 一种从虫生真菌粉质拟青霉 (Paecilomyces farinosus) 分离出的马来酰亚胺，能有效抑制大豆疫霉菌 (Phytophtora sojae)。
