New borrelidins from Onchidium sp. associated StreptomycesolivaceusSCSIO LO13. Chem Biodivers. 2019 Nov 26;: Authors: Zhou Z, Wu Q, Xie Q, Zhang H, Sun C, Ju J Abstract Borrelidins M-O (1-3), along with four previously known family members (4-7), were isolated from marine pulmonated mollusks Onchidium sp. associated Streptomyces olivaceus SCSIO LO13. The structures of 1-3 were elucidated by extensive spectral analyses of HRESIMS, 1D and 2D NMR datasets. In addition, the cytotoxic and antibacterial activities of 1-7 were evaluated enabling us to propose some tentative structure-activity relationships (SARs), especially those involving modifications at C(22) and the moieties at C(7), C(8) of the borrelidin scaffold.

As researchers fight to stop the spread of a novel coronavirus that originated in a seafood market in the central Chinese city of Wuhan, they are facing a counter-intuitive problem: the symptoms can sometimes be so mild in patients that the virus is very difficult to detect. The Wuhan coronavirus, dubbed 2019-nCoV, has killed at least 106 people in mainland China, out of the 4,400-plus documented cases. According to records released by Chinese health authorities, most fatalities were older or had additional health problems. Severe acute respiratory syndrome (SARS), which is related to 2019-nCoV and killed nearly 800 people...
