Abstract
Marine organisms often produce a variety of metabolites with unique structures and diverse biological activities that enable them to survive and struggle in the extremely challenging environment. During the last two decades, our group devoted great effort to the discovery of pharmaceutically interesting lead compounds from South China Sea marine plants and invertebrates. We discovered numerous marine secondary metabolites spanning a wide range of structural classes, various biosynthetic origins and various aspects of biological activities. In a series of reviews, we have summarized the bioactive natural products isolated from Chinese marine flora and fauna found during 2000-2012. The present review provides an updated summary covering our latest research progress and development in the last decade (2012-2022) highlighting the discovery of over 400 novel marine secondary metabolites with promising bioactivities from South China Sea marine organisms.

Abstract
Bioactivity-steered chromatographic purification of the solvent extract of marine sponge Hyrtios erectus (Thorectidae) led to the isolation of three undescribed cyanthiwigin-type diterpenoids, erectcyanthins A-C. Erectcyanthin B exhibited comparable attenuation activity against 3-hydroxy-3-methylglutaryl-coenzyme A reductase (IC50 0.07 mM) with that displayed by anti-dyslipidemic agent atorvastatin (IC50 0.08 mM). Comparatively greater antioxidant properties of erectcyanthin B (IC50 ∼ 0.4 mM) than that displayed by erectcyanthin A (IC50 ∼ 0.5 mM), erectcyanthin C and the standard α-tocopherol (IC50 1.5-1.7 mM) against oxidants also corroborated its promising bioactivity. Erectcyanthin B exhibited considerably greater anti-inflammatory activities (IC50 0.88-1.09 mM) than other erectcyanthin analogues in the series. The potential anti-dyslipidemic activity of erectcyanthins was linearly correlated with electronic parameter (topological polar surface area ∼ 74.6) along with balanced hydrophilic-lipophilic properties (logarithmic octanol-water partition coefficient 1.76). This study recognized the anti-dyslipidemic property of erectcyanthin B as a promising pharmaceutical lead.

Abstract
The tumor suppressor proteins p53 and p27 exhibited a significant role in the survival of cells and regulation of cellular division and growth. In majority of the human tumors, particularly in hepatocellular carcinoma, these proteins are inactivated by mutation or deletion, and are considered to predict the pathophysiology related to liver cancer. The present study evaluated the activation of the p53 and p27 pathways as a useful therapeutic tool to attenuate hepatocellular carcinoma. Three undescribed homologous chromanone derivatives, hyrtiosones A-C were isolated from the organic extract of marine demosponge Hyrtios erectus (family Thorectidae). Preliminary bioactivity assessments found that hyrtiosone A exhibited prospective anti-inflammatory (IC50 1.02-1.86 mM) and antioxidant (IC50 0.74-0.83 mM) properties. Molecular docking analysis of the hyrtiosones using p53-murine double minute complex revealed lesser docking parameters for hyrtiosone A (binding energy -11.12 kcal mol-1, docking score -12.18 kcal mol-1) thereby attributing its greater bioactivity. Hyrtiosone A was furthermore analyzed for in vitro anticancer activity in hepatocellular carcinoma HepG2 cells. Morphological assessment of hyrtiosone A treated HepG2 cell line by acridine orange/ethidium bromide fluorescence staining revealed greater number of apoptotic cells, and was found to be comparable with the cells treated with the standard doxorubicin. Further the Annexin V-fluorescein isothiocyanate assay of hyrtiosone A treated HepG2 cell line by flow cytometry displayed greater number of early apoptotic cells (51.24%) than that exhibited by the standard (21.45%). Cell cycle distribution analysis showed that hyrtiosone A arrested the S and G2/M phase of cell cycle and upregulate the gene expression of p53 and p27 in hepatocellular carcinoma HepG2 cells.

Modulations of Cardiac Functions and Pathogenesis by Reactive Oxygen Species and Natural Antioxidants. Antioxidants (Basel) 2021; 10:antiox10050760.

Abstract
Homeostasis in the level of reactive oxygen species (ROS) in cardiac myocytes plays a critical role in regulating their physiological functions. Disturbance of balance between generation and removal of ROS is a major cause of cardiac myocyte remodeling, dysfunction, and failure. Cardiac myocytes possess several ROS-producing pathways, such as mitochondrial electron transport chain, NADPH oxidases, and nitric oxide synthases, and have endogenous antioxidation mechanisms. Cardiac Ca2+-signaling toolkit proteins, as well as mitochondrial functions, are largely modulated by ROS under physiological and pathological conditions, thereby producing alterations in contraction, membrane conductivity, cell metabolism and cell growth and death. Mechanical stresses under hypertension, post-myocardial infarction, heart failure, and valve diseases are the main causes for stress-induced cardiac remodeling and functional failure, which are associated with ROS-induced pathogenesis. Experimental evidence demonstrates that many cardioprotective natural antioxidants, enriched in foods or herbs, exert beneficial effects on cardiac functions (Ca2+ signal, contractility and rhythm), myocytes remodeling, inflammation and death in pathological hearts. The review may provide knowledge and insight into the modulation of cardiac pathogenesis by ROS and natural antioxidants.

Abstract
The structure of protoaculeine B, the N-terminal residue of the marine peptide toxin aculeine B, is revised to the cis-1,3-disubstituted tetrahydro-β-carboline framework. We prepared two truncated model compounds that lack a long-chain polyamine using the one-step Pictet-Spengler reaction of tryptophan and compared their NMR, mass spectra, and chemical reactivity with those of the natural protoaculeine B. The synthetic models reproduced the profiles of the natural product well, which confirmed the appropriateness of the structure revision.

Abstract
Protein kinases are validated drug targets for a number of therapeutic areas, as kinase deregulation is known to play an essential role in many disease states. Many investigated protein kinase inhibitors are natural product small molecules or their derivatives. Many marine-derived natural products from various marine sources, such as bacteria and cyanobacteria, fungi, animals, algae, soft corals, sponges, etc. have been found to have potent kinase inhibitory activity, or desirable pharmacophores for further development. This review covers the new compounds reported from the beginning of 2014 through the middle of 2019 as having been isolated from marine organisms and having potential therapeutic applications due to kinase inhibitory and associated bioactivities. Moreover, some existing clinical drugs based on marine-derived natural product scaffolds are also discussed.

Thirteen new hydroxylated calyciphylline A-type Daphniphyllum alkaloids (1-13) were isolated from an ethanolic extract of Daphniphyllum himalense. These structures were characterized on the basis of spectroscopic data analysis, especially from their 2D NMR spectra. Oxidation at the C-3, C-9, C-11, and C-12 positions is reported for the first time for this class of compounds. Selective compounds showed low inhibitory rates against three kinase enzymes, PTP1B, aurora A, and IKK-β, at a concentration of 20 μg/mL.

Abstract
A new steroidal ketone (1), with an ergosta-22,25-diene side chain, was obtained from the South China Sea marine sponge Xestospongia testudinaria. The structure of 1 was determined on the basis of detailed spectroscopic analysis and by comparison with literature. Compound 1 exhibited significant inhibitory activity against protein tyrosine phosphatase 1B (PTP1B), a key target for the treatment of type II diabetes and obesity, with an IC50 value of 4.27 ± 0.55 μM, which is comparable with the positive control oleanolic acid (IC50 = 2.63 ± 0.22 μM).

Abstract
Marine indole alkaloids comprise a large and steadily growing group of secondary metabolites. Their diverse biological activities make many compounds of this class attractive starting points for pharmaceutical development. Several marine-derived indoles were found to possess cytotoxic, antineoplastic, antibacterial and antimicrobial activities, in addition to the action on human enzymes and receptors. The newly isolated indole alkaloids of marine origin since the last comprehensive review in 2003 are reported, and biological aspects will be discussed.
