从一株未鉴定的青霉菌（Penicillium sp.）中分离得到环-（L-色氨酸-L-苯丙氨酰），通过与L-色氨酸和L-苯丙氨酸合成的化合物的圆二色谱（CD）比较，确定其绝对构型为C-11和C-14位的S。Cyclo-（L-try-L-Phe）及其组分L-色氨酸和L-苯丙氨酸对供试植物松花粉、茶花粉、莴苣、水芹和水稻种子具有不同的生物活性。因此，环-（L-Trp-L-Phe）的生物活性来自完整的化合物，而不是降解为L-色氨酸和L-苯丙氨酸。
Cyclo-(L-tryptophyl-L-phenylalanyl) was isolated from an unidentified Penicillium sp. The absolute configuration of the compound was confirmed to be S, S at C-11 and C-14 by means of the comparison of the CD spectrum with that of the synthetic compound synthesized from L-tryptophan and L-phenylalanine. Cyclo-(L-try-L-Phe) and its components, L-tryptophan and L-phenylalanine, exhibited different biological activities against the tested plants of pine and tea pollen, lettuce, cress and rice seeds. Therefore, the biological activities of cyclo-(L-Trp-L-Phe) result from the intact compound and not the-degradation to L-tryptophan and L-phenylaianine.
