Quinomycin G (1), a new analogue of echinomycin, together with a new cyclic dipeptide, cyclo-(l-Pro-4-OH-l-Leu) (2), as well as three known antibiotic compounds tirandamycin A (3), tirandamycin B (4) and staurosporine (5), were isolated from Streptomyces sp. LS298 obtained from a marine sponge Gelliodes carnosa. The planar and absolute configurations of compounds 1 and 2 were established by MS,...

Marine sponges which are known to own multiple functional properties have created significant interest among the researchers due to their biological activities and impending application in different industries .The aim of this study was to obtained bioactive components of sponges. Gelliodes carnosa sponge was collected from Nay Band Bay (Persian Gulf waters) and antimicrobial activities of crud...

Salinity and low nitrogen availability are two major abiotic stresses that often coexist disturb plant productivity. This study aimed at investigating the combined effects of salinity (0 100 mM NaCl) (0.5 5.0 NH4NO3) levels on morphological parameters, mineral status, use efficiency, photosynthesis, nitrate reductase (NR, E.C. 1.6.6.1) glutamine synthetase (GS, EC 6.3.1.2) activities Sulla carn...

Eleven pregnanes were isolated from the hydrolysate of the CHCl3 extract fractionated from the caules of Hoya carnosa. Among these, six pregnanes, including 19-acetoxydigipurpurogenin II, were new, and their structures were elucidated. The structures of twenty new pregnane tetraosides and pentaosides, named hoyacarnosides A-T, besides three known ones from the CHCl3 extract, were determined.

The abundances of nine transcripts predicted to encode lignocellulose-modifying enzymes were measured over the course of Phanerochaete carnosa cultivation on four wood species. Profiles were consistent with sequential decay; transcripts encoding lignin-degrading peroxidases featured a significant substrate-dependent response. The chitin synthase gene was identified as the optimal internal refer...

This study investigated the respiratory properties and the role of the mitochondria isolated from one phosphoenolpyruvate carboxykinase (PCK)-CAM plant, Hoya carnosa, in malate metabolism during CAM phase III. The mitochondria showed high malate dehydrogenase (mMDH) and aspartate amino transferase (mAST), and a significant amount of malic enzyme (mME) activities. H. carnosa readily oxidized mal...
