Opis:: Some new dihydropyrano[c]chromenes derivatives are synthesized from 4-hydroxycoumarin. The structure of newly synthesized compounds was confirmed by mass, 1H NMR and IR spectroscopy. Further, antimicrobial screening of these synthesized compounds was done against some bacterial (Gram positive as well as Gram negative) and fungal strains in N,N-dimethylformamide. It is observed that some of synthesized compounds exhibited significant antibacterial activity against Gram positive bacterial strains. The selected fungal strains were most resistant for the studied compounds as none of the synthesized compounds showed activity against any of the fungal strain studied. The best antibacterial activity was shown by ABR-10.

Opis:: Some new chalcones are synthesized by the condensation of aryl ketones with aromatic aldehydes and solubility of these synthesized chalcones is determined in chloroform and dichloromethane at temperatures ranging between 293.15 K and 313.15 K by gravimetric method. The experimental data was correlated well with modified Apelblat equation. Further, from the experimental solubility data, some thermodynamic parameters such as dissolution enthalpy, Gibb’s energy and entropy etc. were evaluated using van’t Hoff equation. The positive Gibb’s energy and negative entropy suggests spontaneous dissolution and more ordered structure in solution.
