The title compound, C(22)H(18)N(2)O(2), was derived from 1-(2-hydroxy-phen-yl)-3-(4-methoxy-phen-yl)propane-1,3-dione. The central pyrazole ring forms dihedral angles of 16.83 (5), 48.97 (4) and 51.68 (4)°, respectively, with the methoxy-phenyl, phenyl and hydroxy-phenyl rings. The crystal packing is stabilized by O-H⋯N hydrogen bonding.

The antibacterial and antifungal activities of three schiff bases were evaluated against some pathogenic bacteria and fungi. Parallel experiments were also carried out with standard drugs (Kanamycin for bacteria and Nystatin for fungi). Two compounds [N-(1-phenyl-2-hydroxy-2phenylethylidine)-2',4' dinitrophenyl hydrazine, abbreviated as PDH and N-(2-hydroxy benzylidine)-2'-hydroxy imine, abbrev...

Photoresponsive molecular devices can be a valuable tool to promote chemical changes in response multiple signals, such as photons and pH, deliver drugs or detect physiological conditions vivo. For example, trans-chalcones (Ct) from 4′-hydroxyflavylium (F1) 7-hydroxyflavylium (F2) undergo cis-trans isomerization by photoreaction into many different structures. The takes place at slow rate pH ch...

4-Hydroxy-5-phenyl-1,3-oxazaperhydroin-2-one has been proposed to be a reactive metabolite of the anti-epileptic drug felbamate [Thompson et al. (1996) Chem. Res. Toxicol. 9, 1225-1229]. 4-Hydroxy-5-phenyl-1,3-oxazaperhydroin-2-one exists in equilibrium with 3-oxo-2-phenylpropyl aminooate, which is known to eliminate to generate 2-phenylpropenal. Thus, this species is postulated to be a latent ...

Overexpression of mutant p53 in cancer cell inactivates the pathways to execute apoptosis and cycle arrest. This study aimed synthesize new kardiena derivative compound, 3-carbethoxy-4(3’-chloro-4’-hydroxy)phenyl-but-3-en-2-one, reactivate Characterization synthetic compound employing melting point, IR, EI-MS, 1H-NMR, 13C-NMR spectra revealed 3-carbethoxy-4(3’-chloro-4’-hydroxy)phenyl-but-3-en-...
