Abstract:

Primary screening of recent collections from the sea around New Zealand revealed a wide range of bioactivities, including antitumour, antiviral and anti-HIV activities. Seven marine organisms, including sponges and an ascidian, were examined to identify the active compounds responsible for these three type of biological activities. A chemical screening protocol was established for the dereplication and prioritization of antiviral natural product extracts, which was also applied to extracts with other bioactivities. A recent modification included HPLC analysis of the eluates from solid phase e

Marine algae have been demonstrated to be strong candidates for the extraction and enforcement of novel drugs and in recent years, significant development has been achieved in the isolation of these active compounds with several activities, such as anticancer, anti-inflammation, antioxidant, and having an inhibitory effect on ROS generation. Reports relevant to the chemical properties of brown algae Padina sp. are limited and those accompanied to a comprehensive evaluation of the biological activity on osteosarcoma (OS) are non-existent.

Actinomycetes and fungi were successfully isolated from both New Zealand and Malaysian marine invertebrates and classified as facultatively marine based on their ability to grow on both sea water and non-sea water media.

Three isolates of Streptomyces spp., four Penicillium spp. and two Paecilomyces spp. whose extracts showed good cytotoxicity were selected for further investigation. A sma
