    Cyclic dipeptide constituents from the mangrove fungus Penicillium oxalicum(No.092007).[Reference: WebLink]
    To study the metabolites of mangrove fungus Penicillium oxalicum from the south China sea and search for new anti-tumor compounds.
    METHODS AND RESULTS:
    Compounds were isolated by silica gel,ODS column chromatography,Sephadex LH-20 column chromatography and reversed-phase HPLC purification.Structural elucidation was achieved by physico-chemical constants and spectroscopic analysis.MTT assay was used to evaluate the bioactivities in vitro. Six cyclic dipeptides were isolated from the acetone extracts of mycelium of fungus and elucidated as cyclo-(Phe-Ile)(1),cyclo-(Phe-Val)(3),cyclo-(Ile-Leu)(3),cyclo-(Val-Val)(4),Cyclo(Pro-Val)(5),cyclo-(Pro-Gly)(6).Coumpouds 2,3 and 5 could evidently inhibit the growth of cancer cell lines HepG Ⅱ and LNCaP at the concentration of 50 μg·mL-1.
    CONCLUSIONS:
    All of Compounds are obtained from the marine fungus for the fist time.Compounds 2,3 and 5 show cytotoxic activity in vitro.

    Antifungal cyclopeptides from Halobacillus litoralis YS3106 of marine origin.[Reference: WebLink]

    METHODS AND RESULTS:
    Three new cyclopeptides, including halolitoralin A (a cyclic hexapeptide), halolitoralin B and C (two cyclic tetrapeptides), together with three known cyclic dipeptides, Cyclo(Pro-Val), cyclo(Pro-Leu) and cyclo(Ile-Val) were isolated from the ferment broth of a marine sediment-derived Halobacillus litoralis YS3106.
    CONCLUSIONS:
    The cyclopeptides show surprisingly simple architectures with highly repeated residue units, which showed moderate antifungal and weak antitumor activities in vitro.
    J Nematol. 2007 Sep;39(3):243-7.
    Two Cyclic Dipeptides from Pseudomonas fluorescens GcM5-1A Carried by the Pine Wood Nematode and Their Toxicities to Japanese Black Pine Suspension Cells and Seedlings in vitro.[Pubmed: 19259494]
    Pseudomonas fluorescens GcM5-1A, isolated from the pine wood nematode (PWN), Bursaphelenchus xylophilus, was cultured in Luria Broth medium (LB).
    METHODS AND RESULTS:
    The clarified culture was extracted with ethyl acetate, and two dipeptides were purified from the extract. The chemical structures of 1 and 2 were identified as Cyclo(Pro-Val)and cyclo(-Pro-Tyr-), respectively, by MS, (1)H NMR, (13)C NMR,(1)H-(1)H COSY, 1H -(13)C COSY spectra.
    CONCLUSIONS:
    Bioassay results showed that the two compounds were toxic to both suspension cells and seedlings of Pinus thunbergii, which may offer some clues to research the mechanism of pine wilt disease caused by PWN.
