A novel series of benzimidazolo thiazolidinones, thiazinones and 5-arylidene-2-imino thiazolidinones were synthesized and evaluated for antibacterial activity. The compounds were synthesized in excellent yield and the structures were characterized on the basis of IR, 1H-NMR and MASS spectral data. Most of the synthesized compounds showed good antibacterial activity against Gram-positive and Gram-negative bacteria. QSAR study was carried out with synthesized compounds using molecular descriptors such as electronic, thermodynamic and steric. Molecular descriptors were used to derive QSAR models between antibacterial activity and structural properties. QSAR study suggested the need of a bulky group to enhance the antibacterial activity in these series of compounds.

D001419	Bacteria	One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.	Eubacteria
