Abstract
Two previously unreported lignans (1-2) and four undescribed [11]-chaetoglobosins (3-6) were obtained from the culture extract of an endophytic fungus Pseudeurotium bakeri P1-1-1. Their structures with absolute configurations were determined by spectroscopic data analysis, single-crystal X-ray diffraction, electronic circular dichroism (ECD) calculations, the modified Mosher's method, and Mo2(OAc)4-induced electronic circular dichroism (ICD) experiments. Compounds 5 and 6 showed moderate cytotoxic effects against seven human cancer cell lines. Compounds 2-4 exhibited immunosuppressive activities on concanavalin A-induced T cell proliferation with IC50 values of 3.7, 3.4, and 14.5 μM, and on lipopolysaccharide-induced B cell proliferation with IC50 values of 4.1, 3.9, and 14.2 μM, respectively. Further investigation revealed that 2 and 3 induced apoptosis in activated T cells in a dose-dependent manner.

Abstract
The present volume is the third in a trilogy that documents naturally occurring organohalogen compounds, bringing the total number-from fewer than 25 in 1968-to approximately 8000 compounds to date. Nearly all of these natural products contain chlorine or bromine, with a few containing iodine and, fewer still, fluorine. Produced by ubiquitous marine (algae, sponges, corals, bryozoa, nudibranchs, fungi, bacteria) and terrestrial organisms (plants, fungi, bacteria, insects, higher animals) and universal abiotic processes (volcanos, forest fires, geothermal events), organohalogens pervade the global ecosystem. Newly identified extraterrestrial sources are also documented. In addition to chemical structures, biological activity, biohalogenation, biodegradation, natural function, and future outlook are presented.

Abstract
Globally, the second most common mortality reason is cancer. There are two types of risk factors for cancer: intrinsic (unmodifiable) and non-intrinsic (modifiable). Bad lifestyle behaviors are among the exogenous non-intrinsic risk factors that can be related to 30-50% of cancer development risk, among which can be counted the Western lifestyle. On the contrary, a potentially good lifestyle model to prevent cancer is the Mediterranean diet (MD), which is a plant-based nutrition model. The Mediterranean diet includes many beneficial nutrients and nutritional substances, such as dietary fibers, fatty acids, anti-oxidant and anti-inflammatory substances, etc. Among these beneficial substances, an important group is the one composed by polyphenols, the most common plant-synthesized secondary metabolites. Being a plant-based nutrition model, the Mediterranean diet provides many polyphenols, such as resveratrol, quercetin, phenolic acids, catechins, anthocyanins, oleocanthal, oleuropein, rosmarinic acid, gallic acid, hesperidin, naringenin, ellagic acid, etc. These substances show anti-proliferative, pro-apoptotic, anti-inflammatory, anti-oxidant, anti-migration, anti-angiogenic, anti-metastatic, and autophagy stimulator effects, which can potentially reduce cancer development risk, as was shown by some in vivo and in vitro studies on this topic. In this review of the literature we shed light on the effects and potential interactions between the Mediterranean diet polyphenols and cancer development.

Abstract
The secondary metabolites isolated from soil fungi have received more and more attention, especially new compounds that exhibited good biological activities. In this review, a total of 546 new compounds are included in the relevant literature since 2011. The new compounds are isolated from soil fungi, We divided these compounds into seven categories, including alkaloids, terpenoids, steroids, ketones, phenylpropanoids, quinones, esters, lactones, etc. In addition, the biological activities and structure-activity relationships of these compounds have also been fully discussed. The activities of these compounds are roughly divided into eight categories, including anticancer activity, antimicrobial activity, anti-inflammatory activity, antioxidant activity, antiviral activity, antimalarial activity, immunosuppressive activity and other activities. Since natural products are an important source of new drugs, this review may have a positive guiding effect on drug screening.

Abstract
Podomycins A-L (1-12), 12 undescribed hypothemycin-type resorcylic acid lactones (RALs), were characterized from Podospora sp. G214, an endophyte harbored in the roots of Sanguisorba officinalis L. Their structures were addressed by spectroscopic data, X-ray crystallography, the modified Mosher's method, together with Mo2(OAc)4- and Rh2(OCOCF3)4-induced electronic circular dichroism (ICD) experiments. Podomycins A-C (1-3) represent the first class of natural RALs with a 13-membered macrolactone ring, while 4-12 are rearranged methoxycarbonyl substituted RALs. Biologically, compounds 2, 6, 8, 10, and 12 displayed immunosuppressive activities against T cell proliferation with IC50 values of 14.5-21.9 μM, and B cell proliferation with IC50 values of 22.3-36.5 μM, respectively. Further mechanism of action research demonstrated that podomycin F (6) distinctly induced apoptosis in activated T cells via MAPKs/AKT pathway.

Abstract
Resorcylic acid lactones (RALs) are fungal polyketides that consist of a β-resorcylic acid residue (2,4-dihydroxybenzoic acid) embedded in a macrolactone ring. RALs exhibit a broad range of biological activities, including anticancer activities. Following discovery of the selective Hsp90 inhibition activity of radicicol, the kinase inhibition activity of hypothemycin, monocillin II, 5Z-7-oxo-zeaenol, and L-783,277 RALs, and the nuclear factor kappa B (NF-κB) inhibition activity of the RAL zearalenone, have attracted great attention as potential therapeutics for cancer treatment. In this minireview, we focus on natural RALs that possess cytotoxic activities [IC50 values < 10 μM (or 4-5 μg/ml)], discussing their structures, isolation, occurrence, biological activities, and anticancer molecular mechanisms.

Abstract
Cancer remains one of the major causes of death worldwide despite the encouraging breakthroughs in the discovery of novel chemotherapeutic agents in recent years. The development of new effective anticancer candidates still represents a challenging endeavor due to the severe anticancer demands and the emergence of drug-resistant, especially multidrug-resistant, cancers. Macrolactones could regulate multiple signaling pathways in cancer cells and demonstrated potential anticancer effects, including inhibition of proliferation, metastasis, and angiogenic activity. Accordingly, macrolactones possess excellent efficacy against both drug-sensitive and drug-resistant cancer cells, and the rational design of macrolactones may provide valuable therapeutic interventions for cancers. The purpose of this review is as follows: (1) outline the recent advances made in the development of 12-, 14-, and 16-membered macrolactones with anticancer potential; (2) summarize the structure-activity relationship; and (3) discuss their anticancer mechanisms.

Abstract
β-Resorcylic acid lactones (RALs) are one of the major polyketides produced by fungi, and some of them have a diverse array of biological activities. Most RALs feature a 14-membered macrocyclic ring fused to β-resorcylic acid (2,4-dihydroxybenzoic acid). In this review, more than 100 RAL-type of compounds are structurally classified into three groups; 14-membered RALs with 17R configuration, 14-membered RALs with 17S configuration, and benzopyranones/benzofuranones, and they are reviewed comprehensively in terms of chemistry, biological activities, and biosynthetic pathways.
