The inevitable consequence of the widespread use of antimicrobial agents has been the emergence of antibiotic resistant pathogens. This necessitates an ever-increasing search for new drugs. In an effort to develop antimicrobial agents, a series of hydrazone 2-6-derivatives were synthesized. These were characterized on the basis of physical and spectroscopic data, and were evaluated for their antimicrobial activity against various bacterial and fungal strains using the disc diffusion method and nutrient agar media. The antioxidant activities of the products were also evaluated. Our data showed that many derivatives have promising activities as antioxidant agents.

We report Ab Initio studies of the electric dipole polarizability of the linear polyacene series benzene through nonacene. A number of Ab Initio studies were done at different levels of theory for benzene, with all remaining Ab Initio calculations being at the B3LYP/6-311G(2d, 1p)//B3LYP/6-311+G(2d, 1p) level of theory. We find that the NN tensor component shows a constant increment of 20 atomic units per ring. AM1 and QSAR-quality empirical calculations show poor absolute agreement with the Ab Initio results but given excellent statistical correlation coefficients with the Ab Initio values. This implies that the results of such cheaper calculations can be suitably scaled for predictive purposes.
