4-Thiazolidinone and its derivatives attracted large attention owing to its diverse pharmaceutical applicability and usefulness for the society. In this context, two important 4-thiazolidinone derivatives namely 2-o-chloro phenyl 3-(benzothiazolyl-2’) hydrazono-5-arylidene-4-thiazolidinone and 2-o-chloro phenyl 3-(benzothiazolyl-2’) hydrazono-5-p-anisilidiene-4-thiazolidinone are synthesized from 2-hydrazinobenzothiazole taking as a origin material. However these compounds are less soluble and small degree of bio-accessible. To get rid out of the problem, inclusion complex of the compound has been prepared with β-cyclodextrin. From the changes in spectral characteristics, physical characteristics and antibacterial activities of the compounds and their respective inclusion complexes justify their formation. Thermodynamic parameters ΔG will predict the formation of inclusion complex. Presence of weak intermolecular forces in between host and guest acknowledged with the change in thermodynamic stability constant parameters.
