“…In 1998, Amano applied the mycelium of Aspergillus melleus to the root system of pine trees [129]; two years after inoculation with PWN, 98% of the pine trees survived as compared with 90% for the control group of untreated pine trees [129]. Then, additional studies were carried out to improve the resistance and survival rate of pine trees against PWD utilizing the microorganisms' growth promoting effect and induction of resistance of pine trees [130][131][132][133][134][135], and other studies focused on treating stumps of dead wood caused by PWN by wood-rotting fungi [136,137]. The main biocontrol microbial groups targeting pine trees are shown in Table 3.…”

Pine wilt disease is a malady caused by a complex interaction of various factors such as pine wood nematodes, host plants, vector insects, associated fungi and bacteria, human economic and logistics activities, and environmental factors. The use of microorganisms to biologically control pine wilt disease is a potentially environmentally friendly means for the prevention and control of the disease. In this study, we carried out a systematic review of the progress in research on the biocontrol of pine wilt disease, by focusing on the pathogenic pine wood nematode, its vector beetle, and the host pine tree species. Then, we discuss the implementation prospects and research trends associated with the biocontrol of pine wood disease. This study provides reference information for the understanding and application of various biocontrol microorganisms in the prevention and control of pine wood disease and for the establishment of an environmentally friendly prevention and control strategy.

Cyclic Dipeptides: The Biological and Structural Landscape with Special Focus on the Anti-Cancer Proline-Based Scaffold

et al. 2021

Cyclic dipeptides, also know as diketopiperazines (DKP), the simplest cyclic forms of peptides widespread in nature, are unsurpassed in their structural and bio-functional diversity. DKPs, especially those containing proline, due to their unique features such as, inter alia, extra-rigid conformation, high resistance to enzyme degradation, increased cell permeability, and expandable ability to bind a diverse of targets with better affinity, have emerged in the last years as biologically pre-validated platforms for the drug discovery. Recent advances have revealed their enormous potential in the development of next-generation theranostics, smart delivery systems, and biomaterials. Here, we present an updated review on the biological and structural profile of these appealing biomolecules, with a particular emphasis on those with anticancer properties, since cancers are the main cause of death all over the world. Additionally, we provide a consideration on supramolecular structuring and synthons, based on the proline-based DKP privileged scaffold, for inspiration in the design of compound libraries in search of ideal ligands, innovative self-assembled nanomaterials, and bio-functional architectures.

From 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‐Phe) (4), and tryptophol (5) by using a combination of ESI‐MS, 1D and 2D NMR spectral data as well as by comparison with previous literature. This is the first report of these compounds from Rhabdastrella globostellata.
