Abstract
Two new pairs of enantiomeric butenolides, (+)- and (-)-suberiteslide A, (+)- and (-)-subertieslide B had been obtained from the marine sponge Suberties sp. The structures with absolute configurations of these compounds were unequivocally determined by spectroscopic analyses and ECD (Electronic Circular Dichroism) method. It was the first separation of butenolides from the marine sponges of genus Suberites. Additionally, the anti-inflammatory, antibacterial and cytotoxic activities of these compounds were evaluated. The result indicated that only (-)-subertieslide B showed weak anti-inflammatory activity with the IC50 value of 40.8 μM.

Abstract
Nine previously undescribed compounds including six tocopherol derivatives (1-6) and three acylphloroglucinol derivatives (7-9) were isolated and characterized from the plants of Dryopteris crassirhizoma. Their structures with absolute configurations were determined by extensive spectroscopic analyses, including IR, HRESIMS, NMR, and calculated electronic circular dichroism (ECD). Compounds 1 and 2 are the first tocopheroid derivatives possessing unique 2,5-dimethylcyclopent-4-ene-1,3-dione carbon skeleton, and compounds 3-6 were new 5a-norcyclopentenones having a spirofused bicyclic carbon skeleton. The biosynthetic pathway of compounds 1-6 was postulated. When combined with fluconazole (FLC), compound 3 showed significant antifungal activity against standard Candida albicans with MIC50 value of 1.19 μg/mL (FLC: 3.41 μg/mL). Furthermore, the anti-plant pathogenic fungi and bacterial activities have been evaluated in vitro, compounds 5 and 8 showed anti-Verticillium dahlia and Sclerotinia sclerotiorum with MIC value of 50 μg/mL, respectively. Compounds 1 and 5 exhibited moderate antibacterial activities against Micrococcus luteus with MIC value of 50 μg/mL, respectively.

Abstract
Marine organisms are recognized as a rich source of bioactive secondary metabolites. The remarkable abundance and diversity of bioactive small molecules isolated from soft corals displayed their essential role in drug discovery for human diseases. Sterols and terpenes, particularly cembranolides, 14-membered cyclic diterpene, demonstrated numerous biological activities, such as antitumor, antimicrobial, antiviral, antidiabetic, anti-osteoporosis and anti-inflammatory. Accordingly, continuous investigation of marine soft corals will be the way for the discovery of a plentiful number of chemical diverse natural products with various biological potentials for prospective pharmaceutical industrial applications. Such review affords plenary inspection of the total secondary metabolites isolated from the Sinularia, from 2008 until 2020, besides their natural sources as well as bioactivities whenever possible.

Abstract
Sinularia is one of the conspicuous soft coral species widely distributed in the world’s oceans at a depth of about 12 m. Secondary metabolites from the genus Sinularia show great chemical diversity. More than 700 secondary metabolites have been reported to date, including terpenoids, norterpenoids, steroids/steroidal glycosides, and other types. They showed a broad range of potent biological activities. There were detailed reviews on the terpenoids from Sinularia in 2013, and now, it still plays a vital role in the innovation of lead compounds for drug development. The structures, names, and pharmacological activities of compounds isolated from the genus Sinularia from 2013 to March 2021 are summarized in this review.

Abstract
The present work reports the bioassay-guided isolation of four bioactive fatty acid derivatives involving a new butenolide, namely sinulolide I (1) together with three known metabolites (2-4) from the deep-sea sediment derived fungus Aspergillus terreus SCSIO 41202. The chemical structure of compound 1 was elucidated based on extensive spectroscopic methods (1D/2D NMR and HR-ESI-MS), optical rotation and circular dichroism analyses, while the structures of the known compounds (2-4) were established by comparison of NMR spectral data with those reported in literature. All of these four compounds (1-4) exhibited significant antifungal activity against citrus postharvest pathogen Penicillium italicum (MICs around 0.031-0.125 mg/mL).

Abstract
The systematic review of the marine pharmacology literature from 2014 to 2015 was completed in a manner consistent with the 1998-2013 reviews of this series. Research in marine pharmacology during 2014-2015, which was reported by investigators in 43 countries, described novel findings on the preclinical pharmacology of 301 marine compounds. These observations included antibacterial, antifungal, antiprotozoal, antituberculosis, antiviral, and anthelmintic pharmacological activities for 133 marine natural products, 85 marine compounds with antidiabetic, and anti-inflammatory activities, as well as those that affected the immune and nervous system, and 83 marine compounds that displayed miscellaneous mechanisms of action, and may probably contribute to novel pharmacological classes upon further research. Thus, in 2014-2015, the preclinical marine natural product pharmacology pipeline provided novel pharmacology as well as new lead compounds for the clinical marine pharmaceutical pipeline, and thus continued to contribute to ongoing global research for alternative therapeutic approaches to many disease categories.

Abstract
Three new cembrene diterpenoids, sarcoehrenbergilid A–C (1–3), along with four known diterpenoids, sarcophine (4), (+)-7α,8β-dihydroxydeepoxysarcophine (5), sinulolide A (6), and sinulolide B (7), and one steroid, sardisterol (8), were isolated and characterized from a solvent extract of the Red Sea soft coral Sarcophyton ehrenbergi. Chemical structures were elucidated by NMR and MS analyses with absolute stereochemistry determined by X-ray analysis. Since these isolated cembrene diterpenes contained 10 or more carbons in a large flexible ring, conformer stabilities were examined based on density functional theory calculations. Anti-proliferative activities for 1–8 were evaluated against three human tumor cell lines of different origins including the: lung (A549), colon (Caco-2), and liver (HepG2). Sardisterol (8) was the most potent of the metabolites isolated with an IC50 of 27.3 µM against the A549 cell line. Since an elevated human-cancer occurrence is associated with an aberrant receptor function for the epidermal growth factor receptor (EGFR), molecular docking studies were used to examine preferential metabolite interactions/binding and probe the mode-of-action for metabolite-anti tumor activity.

The emphasis is on new compounds (1378 in 456 papers for 2014), together with the relevant biological activities, source organisms and country of origin. Reviews, biosynthetic studies, first syntheses, and syntheses that lead to the revision of structures or stereochemistries, have been included.
