Protective Effect of Nicorandil on Contrast-Induced Acute Kidney Injury After Emergency Percutaneous Coronary Intervention.

To investigate the protective effect of nicorandil on contrast-induced acute kidney injury (CIAKI) in patients with acute ST-segment elevation myocardial infarction (STEMI) after emergency percutaneous coronary intervention (PCI). This is a single-center, retrospective control study. A total of 156 patients with STEMI were divided into the nicorandil group (n  =  55) and the control group (n  =  101).

A new α-pyrone from the deep-sea actinomycete Nocardiopsis dassonvillei subsp. dassonvillei DSM 43111(T).

A new α-pyrone, nocapyrone S (1), together with five known compounds (2-6), were isolated from the deep-sea actinomycete Nocardiopsis dassonvillei subsp. dassonvillei DSM 43111(T). Their structures were determined by spectroscopic analyses.

A new sesquiterpene from the gorgonian coral Menella sp.

A new sesquiterpene named menecubebane B (1) and a known analogue (2) were isolated from the gorgonian coral Menella sp. Their structures were elucidated by the extensive analyses of spectroscopic data and by the comparison with related literature. Cytotoxic effect against both Eca9706 and HeLa cell lines was evaluated, revealing 1 exhibited moderate cytotoxicity against the two cell lines involved with IC50 values being 20.
