Diketopiperazines from Rhabdastrella globostellata

Vietnam Journal of Chemistry, 2022
AbstractFrom the methanol extract of the Vietnamese marine sponge Rhabdastrella globostellata (Carter, 1883), four diketopiperazines (1‐4) and one indol alkaloid (5) were isolated by various chromatographic methods. Their chemical structures were identified to be cyclo‐(L‐Pro‐L‐Ile) (1), cyclo‐(L‐Pro‐L‐Leu) (2), cyclo‐(D‐Pro‐L‐Ile) (3), cyclo‐(L‐Pro‐L ...

Oxidation of Tyrosine Diketopiperazine to DOPA Diketopiperazine with Tyrosine Hydroxylase

Journal of Natural Products, 2004
The diketopiperazine of DOPA was synthesized in high yield from the diketopiperazine of tyrosine using PC12 cell lysate, which expresses high levels of tyrosine hydroxylase. This represents the first use of this enzyme to prepare DOPA-containing peptides.
