TL;DR: Four new diketopiperazines including spirobrocazines A-C (1-3) and brocazine G (4) were characterized from the mangrove-derived Penicillium brocae MA-231 and exhibited potent cytotoxicity against both sensitive and cisplatin-resistant human ovarian cancer cells and strong antimicrobial activity against pathogenic Staphylococcus aureus.

TL;DR: Six new disulfide-bridged diketopiperazine derivatives, brocazines A-F (1-6), along with one known analogue (7), were isolated and identified from the cytotoxic extract of Penicillium brocae MA-231, a fungus obtained from the fresh tissue of the marine mangrove plant Avicennia marina.

TL;DR: Two new bisthiodiketopiperazine derivatives are identified from cultivation in a liquid potato-dextrose broth (PDB) culture medium, whereas two new acorane sesquiterpenes were isolated from a rice solid culture medium.

TL;DR: Sumalarins A-C (1-3), the new and rare examples of sulfur-containing curvularin derivatives, along with three known analogues (4-6), were isolated and identified from the cytotoxic extract of Penicillium sumatrense MA-92, a fungus obtained from the rhizosphere of the mangrove Lumnitzera racemosa.

TL;DR: Five new sulfide diketopiperazine derivatives, namely, penicibrocazines A–E (1–5), along with a known congener (6), were isolated and identified from the culture extract of Penicillium brocae MA-231, an endophytic fungus obtained from the fresh tissue of the marine mangrove plant Avicennia marina.
