In the title mol-ecule, C(19)H(22)N(4)O(2)S, the two benzene rings form a dihedral angle of 9.16 (13)°. In the crystal, pairs of weak inter-molecular C-H⋯S hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further linked through weak C-H⋯O inter-actions into sheets parallel to (012).

Three macrocyclic polylactones have been isolated from Penicillium verruculosum. Two were found to be novel and the third to be identical with NG-012(1). Their structures were elucidated by spectroscopic and chemical methods. A full assignment of 1H- and 13C-resonances in acetone-d6 are given for all three compounds. The compounds show antifungal activity.

Geospatial information can act as a thread that can be used to integrate information from heterogeneous sources. It does so by exploiting common location information components that often exist across different domains. As such it has the potential to be a valuable resource in the implementation of the Semantic Web. This paper examines the challenges of adding a geospatial component to the Web,...
