Photinides A-F (1-6), six new unique benzofuranone-derived gamma-lactones, have been isolated from the crude extract of the plant endophytic fungus Pestalotiopsis photiniae. The structures of these compounds were elucidated primarily by NMR spectroscopy, and their absolute configurations were assigned by application of the CD excitation chirality method. Compounds 1-6 displayed modest cytotoxic...

Endophytic Trichoderma is a fungus found in plant tissue and has the potential as biological control agent. The aim of this study was to endophytic isolated from tomato roots, stems leaves Phytophthora infestans fruit rot growth yield plants. treatments that were tested tricoderma plants applied with doses 50, 75, 100 g per plant, respectively. experimental design used completely randomized thr...

The title compound, C(30)H(50)O(3), which was isolated from a marine endophytic fungus, is a new friedelan derivative. The mol-ecule contains five six-membered rings, which exhibit boat (ring A), distorted boat (ring B) and chair (rings C-E) conformations. The crystal structure is stabilized by inter-molecular O-H⋯O hydrogen bonds, which link neighbouring mol-ecules into 12-membered rings.

Three new eremophilane sesquiterpenes (1-3) were isolated from the mangrove endophytic fungus Xylaria sp. BL321 together with 07H239-A (4), a known analogue of the new compounds. The structures of these compounds were elucidated by analysis of their MS, 1D and 2D NMR spectroscopic data. Compound 4 showed activation activity on α-glucosidase at 0.15 μM (146%), and then, 4 gradually produced inhi...

Nine polyketides, including two new benzophenone derivatives, peniphenone (1) and methyl peniphenone (2), along with seven known xanthones (3-9) were obtained from mangrove endophytic fungus Penicillium sp. ZJ-SY₂ isolated from the leaves of Sonneratia apetala. Their structures were elucidated on the basis of MS, 1D, and 2D NMR data. Compounds 1, 3, 5, and 7 showed potent immunosuppressive acti...

Two new secondary metabolites, endomeketals A-B (1-2), a new natural product (3), and a known compound (4) were isolated from the ethyl acetate extract of the endophytic fungus Endomelanconiopsis endophytica A326 derived from Ficus hirta. Their structures were determined on the basis of extensive spectroscopic analysis. All compounds were evaluated for their cytotoxic activities against SF-268,...

The aim of the present study was to isolate, identify and observe antibacterial activity of the endophytic fungi against some pathogenic bacteria as well as to optimize various parameters for maximum production of antibacterial bioactive compounds. Endophytic fungi were isolated from Menthe viridis collected from Khamariya, Jabalpur M.P. (India). Screening of endophytic fungi for in-vitro antib...

The common bean is the most important food legume in the world. We examined the potential of the fungal entomopathogens Beauveria bassiana and Metarhizium anisopliae applied as seed treatments for their endophytic establishment in the common bean. Endophytic colonization in sterile sand:peat averaged ca. 40% higher for fungus treatments and ca. six times higher for volunteer fungi (other fungal...

Halophilic fungi have evolved unique osmoadaptive strategies, enabling them to thrive in hypersaline habitats. Here, we conduct morphological and transcriptomic response of endophytic fungus (Aspergillus montevidensis ZYD4) in both the presence and absence of salt stress. Under salt stress, the colony morphology of the A. montevidensis ZYD4 changed drastically and exhibited decreased colony pig...
