“…Further semi-synthetic analogues, including compounds 91-94, have also been isolated and studied. Desulfohaplosamate (95), haplosamate A (88), and other steroid analogues (96)(97)(98)(99) were evaluated for their interaction with CB1 and CB2 cannabinoid receptors through binding tests [124]. It is worth noting that both steroids containing a phosphate group, namely 88 and 90, were discovered in the polar organic fraction of an Indonesian sponge species called Dasychalina sp.…”

“…Extensive studies of these plants have revealed a wide variety of fungal endophytes present, including species such as Cercospora spp., Cercospora olivascens , Colletotrichum gloeosporioides , Diaporthe sp., Fusarium sp., Lasiodiplodia theobromae , Pestalotiopsis spp., Penicillium sp., Penicillium chermesinum , Xylaria sp., Phoma microchlamidospora , and Phomopsis sp. [ 94 , 95 ]. In addition, a rare di-aromatic steroid ( 60 ) that contains an unusual naphthyl A/B ring system, resembling equilenin, was isolated from a Hawaiian sponge belonging to the genus Strongylophora [ 96 ].…”

This review delves into the investigation of the biological activity and structural diversity of steroids and related isoprenoid lipids. The study encompasses various natural compounds, such as steroids with aromatic ring(s), steroid phosphate esters derived from marine invertebrates, and steroids incorporating halogen atoms (I, Br, or Cl). These compounds are either produced by fungi or fungal endophytes or found in extracts of plants, algae, or marine invertebrates. To assess the biological activity of these natural compounds, an extensive examination of referenced literature sources was conducted. The evaluation encompassed in vivo and in vitro studies, as well as the utilization of the QSAR method. Numerous compounds exhibited notable properties such as strong anti-inflammatory, anti-neoplastic, anti-proliferative, anti-hypercholesterolemic, anti-Parkinsonian, diuretic, anti-eczematic, anti-psoriatic, and various other activities. Throughout the review, 3D graphs illustrating the activity of individual steroids are presented alongside images of selected terrestrial or marine organisms. Additionally, the review provides explanations for specific types of biological activity associated with these compounds. The data presented in this review hold scientific interest for academic science as well as practical implications in the fields of pharmacology and practical medicine. The analysis of the biological activity and structural diversity of steroids and related isoprenoid lipids provides valuable insights that can contribute to advancements in both theoretical understanding and applied research.

“…The results showed that isolates were able to produce amylase, cellulose, lipase, and laccase [50], among which Penicillium sp. 51 and P. chermesimum exhibited strong cellulase activity [91], demonstrating that these fungi could be useful for the production of enzymes of industrial importance.…”

Endophytic fungi have proven their usefulness for drug discovery, as suggested by the structural complexity and chemical diversity of their secondary metabolites. The diversity and biological activities of endophytic fungi from the Terminalia species have been reported. Therefore, we set out to discuss the influence of seasons, locations, and even the plant species on the diversity of endophytic fungi, as well as their biological activities and secondary metabolites isolated from potent strains. Our investigation reveals that among the 200–250 Terminalia species reported, only thirteen species have been studied so far for their endophytic fungi content. Overall, more than 47 fungi genera have been reported from the Terminalia species, and metabolites produced by some of these fungi exhibited diverse biological activities including antimicrobial, antioxidant, antimalarial, anti-inflammatory, anti-hypercholesterolemic, anticancer, and biocontrol varieties. Moreover, more than 40 compounds with eighteen newly described secondary metabolites were reported; among these, metabolites are the well-known anticancer drugs, a group that includes taxol, antioxidant compounds, isopestacin, and pestacin. This summary of data illustrates the considerable diversity and biological potential of fungal endophytes of the Terminalia species and gives insight into important findings while paving the way for future investigations.

“…However, despite the large number of studies, endophytic strains are still not adequately described, taking into account that Hawsworth and Rossman [9] estimated that more than one million species of endophytes may exist. Besides, a considerable amount of work has been carried out exploring the diversity of endophytic fungi, but only a few studies reported their potential as new sources of industrially useful enzymes such as lipases, phytases, proteases and amylases [2,10,11,12,13]. Marques et al [14] reported the production of cellulases and xylanases by 14 strains of endophytic fungi by solid-state fermentation (SSF), using lignocellulosic materials as substrates.…”
