چکیده
The title compound, C(16)H(16)N(2)O, which contains a double bond connecting an azabicyclic ring system to an indol-3-ylmethylene group, crystallizes from a solution in ethyl acetate. The geometries of the two crystallographically independent molecules are nearly identical. The crystal packing of the title compound involves two types of intermolecular hydrogen bond.

The title compounds, C22H20N2O3S, (I), and C22H22N2O3S, (II), crystallize in space groups P-1 and P2(1)2(1)2(1), respectively. The indole rings are planar and the benzene ring of the phenylsulfonyl group makes a dihedral angle with the mean plane of the indole ring of 90.2 (2) degrees in (I) and 94.0 (2) degrees in (II). In both molecules, the double bond connecting the aza-bicyclic and indole ...

متن کاملNovel chemical enhancers of heat shock increase thermal radiosensitization through a mitotic catastrophe pathway.
Radiation therapy combined with adjuvant hyperthermia has the potential to provide outstanding local-regional control for refractory disease. However, achieving therapeutic thermal dose can be problematic. In the current investigation, we used a chemistry-driven approach with the goal of designing and synthesizing novel small molecules that could function as thermal radiosensitizers. (Z)-(+/-)-...
