Hepatitis B drug „Tifentai“ enters clonical research

The drug, developed by Professor Guangyi LIANG of CAS Key Laboratory of Chemistry for Natural Products in Guizhou, is based on chemically synthesized key components of hepatitis B virus which are easy to produce, and has been shown in preclinical studies to be efficient, have a unique site of action and does not lead to resistance.

CAS announces reforms of their institutes

CAS will attempt to streamline their institutes, by removin overlaps and enhancing quality. Wan GANG, Minister of Science and Technology, told Xinhua that, compared with developed countries, China’s science sector is poorly managed and inefficient, with less information sharing and communication; problems that have held back scientific development despite increased investment. The government hopes more commercial enterprises will work with research institutes, but for that to happen, institutes need to be more open and flexible, Wan said. At least 25 companies listed on China’s A-share market are controlled by universities and research institutes with a total market value of about 187.8 billion yuan (30.49 billion US dollars) CAS news release, August 22, 2014

DICP group achieves solar water splitting using a hybrid of photosystem II and artificial photocatalysis

The groups of Jun CHEN and Can LI at Dalian Institute of Chemical Physics describe a system based on plant PSII and inorganic photocatalysts such as Ru/ SrTiO3:Rh, coupled with an inorganic mediator [ Fe(CN)63−/ Fe(CN)64−], all dispersed in aqueous solutions. PSII seems to self-assembly on the inorganic photocatalyst. The activity of this hybrid photosystem is given with 2,489 mol H2 (mol PSII)−1 h−1 under visible light irradiation and also achieved outdoors. CAS news release, August 21, 2014

Chinese team isolates Streptomyces strains from 10.000 m deep Mariana trench, studies antibiotic gene clusters

Groups around Changsheng ZHANG and Wenjun ZHANG from CAS South China Sea Institute of Oceanology and Shandong University isolated various bacteria from 10.000 m deep Mariana trench in the Phillipine Sea. A marine Streptomyces sp. SCSIO 03032 s strain was found to contain gene clusters for 26 secondary metabolites (antibiotics and alkaloids). CAS news release, 19-08-2014
