Abstract
Soft corals and their secondary metabolites represent an exceptional source of potential drugs. In this regard, Sarcophyton glaucum-derived secondary metabolites were examined for their preventive activities against indomethacin-induced gastric ulcer. Extraction and chromatographic processing of a specimen of S. glaucum collected from the Red Sea waters of Jeddah city resulted in the isolation of eight metabolites including two furanone-based cembranoids (1 and 2), two known pyran-based cembranoids (3 and 4), a known aromadendrene derivative (5), a δ-lactone fatty acid derivative (6), and two known gorgostane-type sterols (7 and 8). Compounds 1 and 6 are new chemical structures, named Δ12(20)-sarcophine and sarcoglaucanoate, respectively. In an initial pilot experiment, compounds 1 and 2 showed significant protective activities against indomethacin-induced peptic ulcer in rats. These data were evidenced by their ability to ameliorate the elevated ulcer indices and prevent histopathological alterations observed in the untreated animals. Their effects were mediated by enhanced mucin as shown by Alcian blue and periodic acid-Schiff (PAS) staining of stomach sections. Compounds 1 and 2 exerted significant antioxidant properties as they prevent reduced glutathione (GSH) depletion, malondialdehyde (MDA) accumulation, and superoxide dismutase (SOD) exhaustion. Furthermore, immunohistochemical analyses indicated that both compounds inhibited the expression of interleukin-6 (IL-6) and tumor necrosis-α (TNF-α) as compared to indomethacin alone-treated animals. These actions were accompanied by significant enhancement of tumor growth factor-β (TGF-β) expression. In conclusion, two cembranoids exhibited protective activities against indomethacin-induced peptic ulcer. This is, at least partly, mediated by their pro-mucin, antioxidant, anti-inflammatory, and TGF-β stimulating properties.

Abstract
A C-30 steroid, 3β-,5α-,6β-,11α-,20β-pentahydroxygorgosterol was isolated from the soft coral Xenia umbellata Lamarck (Xeniidae). The chemical structure was elucidated by examining the NMR spectral data and comparison with the previously published data. Compound 1 inhibited the growth of ovarian cancer (SKOV-3), breast cancers (MCF-7 and MDA-MB-231) and hepatocellular carcinoma (HepG2) using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide assay. Notably against HepG2, compound 1 showed significant effect with an IC50 value of 19.70 ± 1.98 µg/mL. It significantly increased the population in the SubG1 phase for 2.01- and 2.05-folds, respectively, compared to untreated cells. Additionally, it showed potent inhibitory activities of superoxide dismutase (384.6 vs 8594.2 U/g protein in dimethyl sulfoxide-treated cells), catalase (0.3 vs 0.07 U/g protein), decreased the level of reduced glutathione (1.7 vs 0.6 mg/g protein) and the activity of matrix metalloproteases (MMP-2 and MMP-9 [0.5-fold of change in MMP activity]) in HepG2 cells. The results indicated the potent antiproliferative activity of the gorgostane derivative (1) against HepG2 cells. This study provides a scientific basis of the antiproliferative effects of steroidal compound with gorgostane nucleus against hepatocellular carcinoma cells.

Abstract
Nowadays, the logarithmic production of existing well-known food materials is unable to keep up with the demand caused by the exponential growth of the human population in terms of the equality of access to food materials. Famous local food materials with treasury properties such as mangrove fruits are an excellent source to be listed as emerging food candidates with ethnomedicinal properties. Thus, this study reviews the nutrition content of several edible mangrove fruits and the innovation to improve the fruit into a highly economic food product. Within the mangrove fruit, the levels of primary metabolites such as carbohydrates, protein, and fat are acceptable for daily intake. The mangrove fruits, seeds, and endophytic fungi are rich in phenolic compounds, limonoids, and their derivatives as the compounds present a multitude of bioactivities such as antimicrobial, anticancer, and antioxidant. In the intermediary process, the flour of mangrove fruit stands as a supplementation for the existing flour with antidiabetic or antioxidant properties. The mangrove fruit is successfully transformed into many processed food products. However, limited fruits from species such as Bruguiera gymnorrhiza, Rhizophora mucronata, Sonneratia caseolaris, and Avicennia marina are commonly upgraded into traditional food, though many more species demonstrate ethnomedicinal properties. In the Middle East, A. marina is the dominant species, and the study of the phytochemicals and fruit development is limited. Therefore, studies on the development of mangrove fruits to functional for other mangrove species are demanding. The locally accepted mangrove fruit is coveted as an alternate food material to support the sustainable development goal of eliminating world hunger in sustainable ways.

Abstract
Chromatographic investigation of the aerial parts of the Rhazya stricta (Apocynaceae) resulted in the isolation of two new monoterpene indole alkaloids, 6-nor-antirhine-N1-methyl (1) and razyamide (2), along with six known compounds, eburenine (3), epi-rhazyaminine (4), rhazizine (5), 20-epi-sitsirikine (6), antirhine (7), and 16-epi-stemmadenine-N-oxide (8). The chemical structures were established by various spectroscopic experiments. Compounds 1–8 exhibited cytotoxic effects against three cancer cells with IC50 values ranging between 5.1 ± 0.10 and 93.2 ± 9.73 µM against MCF-7; 5.1 ± 0.28 and 290.2 ± 7.50 µM against HepG2, and 3.1 ± 0.17 and 55.7 ± 4.29 µM against HeLa cells. Compound 2 showed the most potent cytotoxic effect against all cancer cell lines (MCF-7, HepG2 and HeLa with IC50 values = 5.1 ± 0.10, 5.1 ± 0.28, and 3.1 ± 0.17 µM, respectively). Furthermore, compound 2 revealed a significant increase in the apoptotic cell population of MCF-7, HepG2, and HeLa cells, with 31.4 ± 0.2%, 29.2 ± 0.5%, and 34.9 ± 0.6%, respectively. Compound 2 decreased the percentage of the phagocytic pathway on HepG2 cells by 15.0 ± 0.1%. These findings can explain the antiproliferative effect of compound 2.

Abstract
Purpose: To Investigate the antiproliferative effect of n-hexane-diethyl ether fraction of Costus speciosus (NP) on triple negative breast cancer (MDA-MB-231) cells, and the mechanism involved.
Methods: Maceration with methanol (CH3OH) was used for extraction of Costus speciosus rhizomes. Chromatographic separation was used to obtain the non-polar fraction (NP) via elution with n-hexane:(C2H5)2O at a volume ratio of 9:1. The cytotoxic effect of NP was evaluated against two breast cancer cell lines i.e., triple negative (MDA-MB-231) and positive ER (MCF-7) employing 3-(4,5- dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) MTT) assay, and the IC50 values were estimated. Cell cycle was determined with flow cytometry, while the likely mechanism involved in the cytotoxic effect was investigated using comet assay, immunofluorescence, clonogenic and scratch assays, zymography and detection of the antioxidant markers.
Results: NP produced potent cytotoxicity against MDA-MB-231, with IC50 value of 4 ± 0.03 μg/mL, whereas its IC50 for MCF-7 was 27 ± 1.3 μg/mL. It induced apoptosis via cell cycle arrest at G1 phase. Moreover, NP markedly decreased levels of superoxide dismutase (SOD), reduced glutathione (GSH), and matrix metalloprotease-2 (MMP-2), in MDA-MB-231 cells. Moreover, it inhibited cancer cell migration and colony formation.
Conclusion: Non-polar fraction of Costus speciosus (NP) exerted cytotoxic effect on triple negative breast cancer cells (MDA-MB-231) and positive ER (MCF-7). It inhibited cancer cell migration and colony formation. Interestingly, NP arrested the breast cancer cell cycles at sub-G1 phase, inhibited SOD and MMP-2, and decreased GSH levels. It induced apoptosis via DNA damage, downregulation of mutant p53, and over-expressions of the cell cycle inhibitors p21 and p27.

Abstract
From the soft coral Xenia umbellata, seven isoprenoid derivatives were isolated, including a new xenicane diterpene, xeniolide O (5) and a new gorgostane derivative gorgst-3β,5α,6β,11α,20(S)-pentol-3-monoacetate (7), along with three known sesquiterpenes (1-3), a known diterpene (4), and a known steroid (6). The extensive analyses of the NMR, IR, and MS spectral data led to determination of their chemical structures. Compounds 1-7 displayed a cytotoxic effect against breast adenocarcinoma (MCF-7), hepatocellular carcinoma (HepG2), and cervix adenocarcinoma (HeLa), with IC50 values ranging between 1.5 ± 0.1-23.2 ± 1.5; 1.8 ± 0.1-30.6 ± 1.1 and 0.9 ± 0.05-12.8 ± 0.5 μg/mL, respectively. Compound 3 showed potent cytotoxic effects against MCF-7, HepG2, and HeLa with IC50 values = 2.4 ± 0.20, 3.1 ± 0.10 and 0.9 ± 0.05 μg/mL, respectively. Compounds 2, 5, and 7 displayed cytotoxic effect against Hela cells with IC50 values = 12.8 ± 0.50, 6.7 ± 1.00 and 11.5 ± 2.20 μg/mL, respectively. Two DNA binding dyes, acridine orange (AO) and ethidium bromide (EtBr) were used for the detection of viable, apoptotic, and necrotic cells. The early apoptotic cell death was observed in all types of treated cells. The late apoptotic cells were highly present in HepG2 cells. Compounds 5 and 7 induced a high percentage of necrosis towards HepG2 and HeLa cells. The late apoptosis was recorded as a high rate after treatment with 7 on all cancer cells.

Abstract
By the end of the twentieth century, the interest in natural compounds as probable sources of drugs has declined and was replaced by other strategies such as molecular target-based drug discovery. However, in the recent times, natural compounds regained their position as extremely important source drug leads. Indole-containing compounds are under clinical use which includes vinblastine and vincristine (anticancer), atevirdine (anti-HIV), yohimbine (erectile dysfunction), reserpine (antihypertension), ajmalicine (vascular disorders), ajmaline (anti-arrhythmic), vincamine (vasodilator), etc. Monoterpene Indole Alkaloids (MIAs) deserve the curiosity and attention of researchers due to their chemical diversity and biological activities. These compounds were considered as an impending source of drug-lead. In this review 444 compounds, were identified from six genera belonging to the family Apocynaceae, will be discussed. These genera (Alstonia, Rauvolfia, Kopsia, Ervatamia, and Tabernaemontana, and Rhazya) consist of 400 members and represent 20% of Apocynaceae species. Only 30 (7.5%) species were investigated, whereas the rest are promising to be investigated. Eleven bioactivities, including antibacterial, antifungal, anti-inflammatory and immunosuppressant activities, were reported. Whereas cytotoxic effect represents 47% of the reported activities. Convincingly, the genera selected in this review are a wealthy source for future anticancer drug lead.

Abstract
:
Rhazya stricta is a rich indole alkaloid medicinal plant species, that is used in traditional
medicine particularly in Middle East countries to treat inflammations, diabetes, rheumatism, and skin
disorders. The alkaloid plant extract of R. stricta was fractionated on aluminum oxide column and further
purified by different chromatographic methods. The chemical structures of the isolated compounds
were elucidated by interpretation of their 1D and 2D NMR, IR, UV and MS spectral data. The potential
antitumor effect was examined against three cancer cell lines; HCT-116-colon cancer, PC-3-prostate
cancer and HepG2-liver cancer as well as a control cell line (Vero) using MTT assay. Two new indole
alkaloids, identified as 16-epi-stemmadenine-N-oxide (1) and stemmadenine-N-methyl (2), along with
the known indole alkaloid 20-epi-antirhine (3) were isolated from the leaves of Rhazya stricta. Compound
2, stemmadenine-N-methyl exhibited a reasonable selectivity index and a broad anticancer effect
against the examined cell lines with IC50 35.0±0.7, 35.0±0.6, 40.0±0.7and 79.0±1.0 μM, respectively.
Furthermore, the effect of stemmadenine-N-methyl was evaluated on cell migration using woundhealing
assay. It significantly hindered cell migration and delayed-wound healing. 16-epistemmadenine-
N-oxide and stemmadenine-N-methyl are new indole alkaloids isolated from the leaves
of Rhazya stricta, of which stemmadenine-N-methyl selectively inhibited the proliferation of three different
cancer cell lines. In addition, it prevented cell migration and delayed wound-healing. Further
studies are required to confirm the mechanism by which this promising alkaloid exhibits its antitumor
activity.

Abstract
Three previously undescribed compounds, maneonenes and isomaneonene derivatives; in addition to five known compounds, two cuparene, one chamigrene, and two cis-maneonenes were isolated from the Red Sea red alga Laurencia obtusa. The chemical structures of all unknown metabolites were characterized employing spectroscopic methods and then were further confirmed by single crystal X-ray analysis. Jeddahenyne A has C-5-C-12 etheric linkage and C-13-C-14 carbon-carbon double bond; Jeddahenyne B has in addition to the aforementioned etheric linkage a C-13 carbonyl function and absence of halogenation, unusual features for the maneonenes while 12-debromo-12-methoxy isomaneonene A shows unrecorded methoxylation at C-12. The apoptosis-inducing or inhibiting effect of both compounds on apoptosis of peripheral blood neutrophils was studied.

Abstract
AbstractPurification of the organic extract of Laurencia obtusa Lamouroux by column chromatography and preparative thin layer chromatography provided four new compounds: a eudesmane-type sesquiterpenoid [eudesma-4(15),11-diene-5,7-diol (1)], a cuparane-type sesquiterpenoid [10-hydroxycuparaldehyde (2)], and two nor-cuparanes [3-hydroxy-15-nor-cuparan-10β-ol (3) and 2-bromo-3-hydroxy-15-nor-cuparan-10β-ol (4)]. Structural identification was made possible by comparison of spectral data with those reported in the literature. Compounds 3 and 4 are significant as nor-cuparanes are rarely isolated from marine environment. 1 showed moderate anticandidal activity, whereas 2 exhibited reasonable antibacterial activity against multidrug-resistant bacteria (especially Gram-positive). All the compounds are nontoxic to Artemia salina.

Abstract
Chromatographic fractionation of the CH₂Cl₂/MeOH extract of the Red Sea red alga Laurencia obtusa gave two new hexahydrofuro[3,2-b]furan-based C15-acetogenins, namely, isolaurenidificin (1) and bromlaurenidificin (2). The chemical structures were elucidated based on extensive analyses of their spectral data. Compounds 1 and 2 showed no toxicity (LC50 > 12 mM) using Artemia salina as test organism. Both compounds showed weak cytotoxicity against A549, HepG-2, HCT116, MCF-7, and PC-3 cells, however, they exhibited a relatively potent cytotoxic activity against peripheral blood neutrophils. This can be attributed partly to induction of apoptosis.
