Streptomyces nigra sp. nov. Is a Novel Actinobacterium Isolated From Mangrove Soil and Exerts a Potent Antitumor Activity in Vitro

Frontiers in Microbiology, 2018
A new bacterial strain, designated 452T, was isolated from the rhizosphere soil of the mangrove Avicennia marina in China. As determined, its cell wall peptidoglycan contained LL-diaminopimelic acid; MK-9(H8) and MK-9(H6) were the major isoprenoid ...

A new diketopiperazine from the gorgonian coral Menella kanisa

, 2014
Chemical investigation on the gorgonian Menella kanisa collected from Beibu Gulf led to the isolation of a new diketopiperazine, named menazepine A (1), as well as three known diketopiperazines, namely cyclo(4-hydroxyprolylleucyl) (2), cyclo(Pro-Leu) (3)

Structural elucidation and antimicrobial activity of a diketopiperazine isolated from a Bacillus sp. associated with the marine sponge Spongia officinalis

, 2019
A diketopiperazine (3S, 6S)-3,6-diisobutylpiperazine-2,5-dione was isolated from a sponge-associated microbe for the first time and characterized by FTIR, HRESI-MS, 1H, 13C NMR and 2D NMR. The source is novel for this compound. Single crystal XRD of this

Selective Binding of Two-Armed Diketopiperazine Receptors to Side-Chain-Protected Peptides

, 2002
The binding properties of two-armed receptors based on a diketopiperazine template toward side-chain-protected peptides have been elucidated. Selective binding of these diketopiperazine receptors is not limited to side-chain-free peptides, but ...

Insights into the Bioactivities and Mechanism of Action of the Microbial Diketopiperazine Cyclic Dipeptide Cyclo(L-leucyl-L-prolyl)

Marine Drugs
Diketopiperazines (DKPs) are biologically important cyclic dipeptides widespread in nature, associated primarily with microorganisms. This is the case for the 2,5-DKP derivative cyclo(L-Leu-L-Pro) (cLP), also known as gancidin W or PPDHMP, identified ...
