Exploring seascape genetics and kinship in the reef sponge Stylissa carteri in the Red Sea
A main goal of population geneticists is to study patterns of gene flow to gain a better understanding of the population structure in a given organism. To date most efforts have been focused on studying gene flow at either broad scales to identify barriers to gene flow and isolation by distance or at fine spatial scales in order to gain inferences regarding reproduction and local dispersal. Few...
متن کاملCytotoxic Compounds from the Saudi Red Sea Sponge Xestospongia testudinaria
Bioassay-guided fractionation of the organic extract of the Red Sea sponge Xestospongia testudinaria led to the isolation of 13 compounds including two new sterol esters, xestosterol palmitate (2) and xestosterol ester of l6'-bromo-(7'E,11'E,l5'E)-hexadeca-7',11',l5'-triene-5',13'-diynoic acid (4), together with eleven known compounds: xestosterol (1), xestosterol ester of 18'-bromooctadeca-7'E...
متن کاملCytotoxic polyacetylenes from the Red Sea sponge Siphonochalina siphonella.
Two new polyacetylenes, callyspongenol-D (1) and callyspongendiol (2), the known polyacetylene dehydrosiphonochalynol (3), and the known triterpenoid sipholenol-A (4) were isolated from the Red Sea sponge Siphonochalina siphonella. Their chemical structures were elucidated on the basis of spectroscopic analyses. The cytotoxicity of the isolated compounds towards the human mammary carcinoma cell...
متن کاملMarine natural products: new results from Red Sea invertebrates
New metabolites isolated from soft corals and sponges of the Red Sea are discussed. It is the aim of this report to describe several marine natural products which have recently been isolated and identified by us. The report will include metabolites of sponges and soft corals collected in the straits of the Gulf of Eilat and the Gulf of Suez, The Red Sea(Ref.1). Diterpenoids from Spongia arabica...
متن کاملMirabolides A and B; New Cytotoxic Glycerides from the Red Sea Sponge Theonella mirabilis
As a part of our continuing work to find out bioactive lead molecules from marine invertebrates, the CHCl₃ fraction of the organic extract of the Red Sea sponge Theonella mirabilis showed cytotoxic activity in our primary screen. Bioassay-guided purification of the active fractions of the sponge's extract resulted in the isolation of two new glycerides, mirabolides A and B (1 and 2), together w...
