Nd fatty acids [46], needs to be deemed. As suggested by Carvajal et al. [24], synergistic effects of the antioxidant compounds inside the extracts shouldn’t be ruled out. Substantial perform has been completed to recognize low-molecular-weight cytotoxic compounds from medicinal mushrooms and their doable modes of action [47]. The cytotoxic and apoptotic effects of triterpenoids, which include ganoderic acids from G. lucidum [32,34] and inotodiol in the sclerotium of I. obliquus [48], have already been documented. Other classes of potentially cytotoxic metabolites are fatty acids, their conjugated forms, and sterols. Probably the most abundant fatty acid in the extracts of L. rhinocerotis was linoleic acid, followed by palmitic and steric acids. Previously, it was reported that linoleic acid did not exert development inhibition against the testosterone-dependent MCF-7aro cell [49]. Palmitic acid, however, has been shown to induce apoptosis in human leukemic cells (MOLT-4) [50], and stearic acid was reported to inhibit colony-forming skills of human cancer cells [51].Bioactivity Evaluation and Chemical Profiling of Lignosus rhinocerotisThe possible of mycelium and culture broth as a substitute for sclerotiumThe aqueous methanol extracts, composed of low-molecularweight compounds, from the mycelium and culture broth of L. rhinocerotis showed comparable bioactivities to the sclerotium. In the antioxidant capacity assays, LR-BT was by far the most potent extract with respect to its ABTS radical scavenging activity, ferric and cupric ion lowering capacities, ferrous ion chelating potential, and inhibitory effect on lipid peroxidation. This indicated that, with regards to antioxidant capacity (Table 1), the sclerotium is not superior compared to the mycelium and culture broth. Secondly, benefits in the MTT assay showed that all extracts were noncytotoxic (IC50.200 mg/ml) against a panel of mammalian cell lines. This implied that L. rhinocerotis from various morphological/developmental stages (i.e., mycelium and sclerotium) usually do not include low-molecular-weight, cytotoxic compounds in abundance. It ought to be noted that within this study, an exhaustive extraction making use of aqueous methanol was employed; therefore, the resulting extracts would contain lower proportions of non-polar constituents than extracts ready from other solvents, such as hexane, chloroform, dichloromethane and/or ethyl acetate. A far more detailed investigation (e.g., successive extraction utilizing solvents of escalating polarity and/or fractionation of the aqueous methanol extracts) is warranted should bio-prospecting of cytotoxic metabolites from L. rhinocerotis be desired. Based on Lau et al. [2], the proximate composition and a few nutritional attributes of the mycelium have been comparable to these on the sclerotium.1346809-61-7 Formula This has provided a basis for thinking about the mycelium an option for the sclerotium.204376-48-7 Chemscene The substantial chemical profiling by GC-MS, UHPLC-ESI-MS/MS, SDSPAGE, and SELDI-TOF-MS in this investigation offered insight into the nature of distinctive low-molecular-weight compounds in L.PMID:33590992 rhinocerotis; nevertheless, further confirmation of those compounds would call for extra chemical investigation which can be currently in progress. Previously, we discovered that protein profiles of L. rhinocerotis cultured within a stirred tank reactor and static cultures have been diverse [9]. Our benefits here demonstrated that culture situations also impacted the composition of low-molecular-weight compounds and their bioactivities. The stro.
