Cyclo(Tyr-Leu) 是一种来自马齿苋 Portulaca oleracea Linn 的环状二肽，具有细胞毒性、抗真菌和抗凝血活性。

Cyclo(Tyr-Leu) is a cyclic dipeptide from Portulaca oleracea Linn with cytotoxicity, antifungal, and anticoagulant activities.

Bacillus associated with an entomopathogenic nematode is shown to produce diketopiperazine (DKP) that showed stronger antifungal activity against Colletotrichum gloeosporioides [minimum inhibitory concentration (MIC): 8 μg mL(- 1)] than commercial fungicide oligochitosan (MIC: 125 μg mL(- 1)). DKP identified as cyclo(D-Tyr-L-Leu) was isolated for the first time from a natural source with a d-tyrosine residue[1].
