Two novel aspochalasins, 20-β-methylthio-aspochalsin Q (named as aspochalasin V), (1) and aspochalasin W (2), were isolated from culture broth of Aspergillus sp., which was found in the gut of a marine isopod Ligia oceanica. The structures were determined on the basis of NMR and mass spectral data analysis. This is the first report about methylthio-substituted aspochalasin derivatives. Cytotoxi...
1. We have identified a Ca(2+)-mobilizing receptor that responds to extracellular ATP (0.1-1000 microM) in a salivary epithelial cell line (ST885). The activated receptor also stimulates Ca2+ entry from the extracellular fluid. 2. The receptor shows an agonist selectivity profile consistent with the behaviour of the nucleotide receptor class. In particular, the pyrimidine nucleotide, UTP, was e...
1'-Diphenylphosphino-1-{[(2-(methylthio)ethyl)amino]carbonyl}ferrocene (1), accessible via amidation of 1'-(diphenylphosphino)ferrocene-1-carboxylic acid (Hdpf) with 2-(methylthio)ethylamine, reacts with [PdCl2(cod)] (cod = cycloocta-1,5-diene) at a 1 : 1 metal-to-ligand ratio to give trans-[PdCl2(1-κ(2)P,S)] (trans-2) as the sole product. A similar reaction with [PtCl2(cod)] affords a mixture ...
