The present invention provides novel compounds of the Formula (I): A-B, its prodrug forms, or pharmaceutically acceptable salts thereof, wherein A represents a saturated, unsaturated, or a partially unsaturated bicyclic heterocyclic ring structure, and B represents an aryl or a heteroaryl group. Preferred compounds of the present invention comprise a benzimidazole or indole nucleus. The compounds of this invention are inhibitors of serine proteases, Urokinase (uPA), Factor Xa (FXa), and/or Factor VIIa (FVIIa), and have utility as anti cancer agents and/or as anticoagulants for the treatment or prevention of thromboembolic disorders in mammals.

Two new ZnII complexes of 2-(2-hydroxyphenyl)benzimidazole (Hpbm), and 5-amino-2-(1H-benzoimidazol-2-yl)phenol (Hapbm), namely [Zn(pbm)2] (1), and [Zn(apbm)2]·C2H5OH·H2O (2), as well as the ligands themselves, have been prepared and characterized by X-ray crystallography and photoluminescencestudies. Both 1 and 2 are neutral, mononuclear molecules that display strong photoluminescence in the blue

Schiff-base probe possessing multiple binding sites was synthesized which is capable of showing Aggregation Induced Emission (AIE) properties. Probe 1 behaves as a fluorescence “turn-on” chemosensor, showing interactions with Pb2+ and Al3+ ions in H2O-CH3CN solvent at pH≈7. The binding constant and detection limit for all the ions were calculated. The binding properties of probe 1 with all the ions were checked
