Further Investigation of the Mediterranean Sponge Axinella polypoides: Isolation of a New Cyclonucleoside and a New Betaine

An exhaustive exploration into the metabolic content of the Mediterranean sponge Axinella-polypoides resulted in the isolation of the new betaine 5 and the new cyclonucleoside 8. The structures of the new metabolites were elucidated by spectroscopic methods assisted by computational methods. The analysis also provided evidence that the sponge does not elaborate pyrrole-imidazole alkaloids (PIAs...

Investigation of antibacterial activities of sponge Axinella sinoxea’s extracts from Larak Island, Persian Gulf

Sponges are the most primitive and simplest multicellular animals. These organisms don’t have any mechanical defense system, so their early appearance in evolution has given them a lot of time for the development of advanced secondary metabolites as chemical defense system. Sponges have the potential to provide drugs from chemical components against diseases, such as antibacterial. Antimicrobia...

Collagen from the Marine Sponges Axinella cannabina and Suberites carnosus: Isolation and Morphological, Biochemical, and Biophysical Characterization

In search of alternative and safer sources of collagen for biomedical applications, the marine demosponges Axinella cannabina and Suberites carnosus, collected from the Aegean and the Ionian Seas, respectively, were comparatively studied for their insoluble collagen, intercellular collagen, and spongin-like collagen content. The isolated collagenous materials were morphologically, physicochemic...

The effect of Hydro-alcoholic extract of pumpkin seeds on Oogenesis and Hormone-Pituitary-Ovarian Axis in Mature Rats

Introduction: In traditional medicine, pumpkin seeds are prescribed and used commonly as energetic and sexual enhancer substances. This study was planned and carried out in order to fill the gap caused by the lack of sufficient scientific evidence on the effect of this substance on oogenesis and hormone-pituitary-ovarian axis. Revealing the effect of hydro-alcoholic extract of pumpkin seeds on ...
