Abstract
Culex pipiens mosquitoes are vectors to many viruses and can transmit diseases such as filariasis and avian malaria. The present study evaluated the larvicidal activity of marine-derived endophytic fungi Aspergillus nomius and Aspergillus flavus from the soft coral Sarcophyton ehrenbergi along with two known cyclodepsipeptide compounds, scopularide A (1) and B (2), isolated from A. flavus extract, against third-instar larvae of C. pipiens, using distilled water as a negative control and toosenedanin as a positive control. The structures of the isolated compounds were confirmed by various spectroscopic analyses. The lethal concentrations (LC50 and LC90) were calculated by probit analysis. Scopularide A was the most potent after 96 h treatment, with LC50 and LC90 values of 58.96 and 994.31 ppm, respectively, and with 82.66% mortality at a concentration of 300 ppm. To unravel the biochemical mechanism of the tested extracts and compounds, their effects against protease, chitinase, phenoloxidases and lipase enzymes from the whole-body tissue of C. pipiens were evaluated after 72 h treatment at LC50 dose. Superior activity was observed for A. flavus extract against all tested enzymes. A molecular docking study was conducted for scopularide A and B on the four tested enzymes, to further verify the observed activity. Results revealed good binding affinities for both compounds as compared to the docked ligands, mainly via a number of hydrogen bonds. This was the first study to report the isolation of endophytic fungi A. flavus and A. nomius from the marine soft coral S. ehrenbergi. The endophytic fungal extract of A. flavus was found to be a promising source for a natural larvicidal agent against C. pipiens populations.

Abstract
Prickly pear fruit peel constitutes a high percentage of the fruit and could be a natural, economic agro-industrial waste of potential use in the nutraceutical industry. This study aimed to isolate and characterize the main constituents of the fruit peel and evaluate its antibacterial activity. A methanol extract was successively fractionated using hexane, chloroform and ethyl acetate. The n-hexane fraction was evaluated for its fatty acid content using gas chromatography mass spectrometry (GC-MS), revealing linolenic acid (omega-3) as the major fatty acid (60.56%), while an ethyl acetate fraction was analyzed using ultra-performance liquid chromatography electrospray tandem mass spectrometry (UPLC-ESI-MS/MS), resulting in the identification of 6 phenolic acids and 9 flavonoids, where caffeic acid (43.69%) and quercetin (14%) were found the most abundant. The ethyl acetate fraction was subjected to column chromatography, resulting in the isolation of four flavanols, viz. astragalin (1), quercetin 5,4'-dimethyl ether (2), isorhamnetin-3-O-glucoside (3) and isorhamnetin (4). Antibacterial evaluation revealed that the EtOAc fraction is the most potent active fraction against the selected pneumonia pathogens, and quercetin 5,4'-dimethyl ether (2) is the most active among the isolated compounds. Virtual docking of the isolated compounds showed promising in silico anti-quorum sensing efficacy, indicating that they could represent natural antibacterial agents. These findings indicate that the unused waste from prickly pear fruits contains valuable constituents that have beneficial potential against some pneumonia pathogens.

Abstract
One of the most widely distributed soft coral species, found especially in shallow waters of the Indo-Pacific region, Red Sea, Mediterranean Sea, and also the Arctic, is genus Sacrophyton. The total number of species belonging to it was estimated to be 40. Sarcophyton species are considered to be a reservoir of bioactive natural metabolites. Secondary metabolites isolated from members belonging to this genus show great chemical diversity. They are rich in terpenoids, in particular, cembranoids diterpenes, tetratepenoids, triterpenoids, and ceramide, in addition to steroids, sesquiterpenes, and fatty acids. They showed a broad range of potent biological activities, such as antitumor, neuroprotective, antimicrobial, antiviral, antidiabetic, antifouling, and anti-inflammatory activity. This review presents all isolated secondary metabolites from species of genera Sacrophyton, as well as their reported biological activities covering a period of about two decades (1998-2019). It deals with 481 metabolites, including 323 diterpenes, 39 biscembranoids, 11 sesquiterpenes, 53 polyoxygenated sterols, and 55 miscellaneous and their pharmacological activities.

Abstract
Fifteen pyrrole alkaloids were isolated from the Red Sea marine sponge Stylissa carteri and investigated for their biological activities. Four of them were dibrominated [(+) dibromophakelline, Z-3-bromohymenialdisine, (±) ageliferin and 3,4-dibromo-1H-pyrrole-2-carbamide], nine compounds were monobrominated [(-) clathramide C, agelongine, (+) manzacidin A, (-) 3-bromomanzacidin D, Z-spongiacidin D, Z-hymenialdisine, 2-debromostevensine, 2-bromoaldisine and 4-bromo-1H-pyrrole-2-carbamide)] and finally, two compounds were non-brominated derivatives viz., E-debromohymenialdisine and aldisine. The structure elucidations of isolated compounds were based on 1D & 2D NMR spectroscopic and MS studies, as well as by comparison with literature. In-vitro, Z-spongiacidin D exhibited a moderate activity on (ARK5, CDK2-CycA, CDK4/CycD1, VEGF-R2, SAK and PDGFR-beta) protein kinases. Moreover, Z-3-bromohymenialdisine showed nearly similar pattern. Furthermore, Z-hymenialdisine displayed a moderate effect on (ARK5 & VEGF-R2) and (-) clathramide C showed a moderate activity on AURORA-A protein kinases. While, agelongine, (+) manzacidin A, E-debromohymenialdisine and 3,4-dibromo-1H-pyrrole-2-carbamide demonstrated only marginal inhibitory activities. The cytotoxicity study was evaluated in two different cell lines. The most effective secondary metabolites were (+) dibromophakelline and Z-3-bromohymenialdisine on L5178Y. Finally, Z-hymenialdisine, Z-3-bromohymenialdisine and (±) ageliferin exhibited the highest cytotoxic activity on HCT116. No report about inhibition of AURORA-A and B by hymenialdisine/hymenialdisine analogs existed and no reported toxicity of ageliferin existed in literature.

Abstract
Thymus vulgaris, (Lamiaceae), essential oils composition and yield, were found to be greatly influenced by water stress and growth enhancers. Therefore, three controlled cultivation conditions were applied to achieve the highest essential oil productivity of T. vulgaris. The essential oils obtained by hydro-distillation of the aerial parts were analyzed using (GC-MS). The tested plant subjected to drought showed a 66% increase in the essential oil yield, while those subjected to drought stress and foliar spray showed 57.1% increase and the regularly irrigated group with foliar spraying showed 23.8% increase relative to the control group. The cytotoxic activity of T. vulgaris essential oils was evaluated against lung (A-549), colon (HCT-116), intestinal (CACO2) and breast (MCF-7) carcinoma using the cell viability assay. The lowest IC50 values 0.44 and 0.33 μg/mL were seen against (HCT-116) and (CACO2) cells respectively. These IC50 values were lower than that of doxorubicin used as reference drug.

Abstract
One high-performance liquid chromatographic (HPLC) and two thin-layer chromatographic (TLC) methods are proposed for the determination of colchicine in crude drugs and pharmaceutical preparations. The TLC scanner method is based on measurement of the absorbance of the separated colchicine spot; alternatively, after scraping the spot from the plate and elution the absorbance can be measured spectrophotometrically. The HPLC assay was carried out isocratically on a reversed-phase column using MeOH-H2O (60 + 40). The recoveries were 99.2 +/- 1.23, 99.1 +/- 1.12 and 99.1 +/- 2.01% for the TLC scanner, spectrophotometric and HPLC methods, respectively. The methods were shown to be sensitive and specific and can be used as an alternative to the pharmacopoeial methods having been applied to the determination of colchicine in corms of Merendera persica and in three pharmaceutical preparations.
