In order to get a clearer view on the active geometry of anti-invasive chalcones, we have prepared a number of isoxazoles and related substances as conformationally restrained mimics of 1,3-diarylpropenones, and also of (Z)-stilbenes. In vitro anti-invasive activity data for 3,5-isoxazoles and 4,5-isoxazoles, together with an in silico geometrical comparison, point towards an active conformation for chalcones more resembling their s-trans geometry than the s-cis counterpart.

Chemistry and nonlinear optical properties of new 2H-benzotriazole derivatives
The 2H-benzotriazolyl group is introduced as a new electron-withdrawing group for NLO-active chromophores. Novel benzotriazole derivatives and hydrazones have been synthesized. While their electronic structure and acceptor capability is comparable to those of structurally related nitro compounds, 2H-benzotriazoles show a more favorable transparency-nonlinearity trade-off for NLO applications. The first
