Several compounds bearing the indolinone chemical scaffold are known to possess anticancer properties. For example, the tyrosine kinase inhibitor sunitinib is an arylideneindolin-2-one compound. The chemical versatility associated with structural modifications of indolinone compounds underlies the potential to discover additional derivatives possessing anticancer properties. Previously synthesi...

the equilibrium constant of adduct formation between some triorganotin chloride of the type r3sncl (r=c6h5, p-ch3c6h4, n-ch3)ch2)3, c6h5-ch2 and lewis bases cl¯, br¯, and i¯, were measured in 50% v/v ethanol-water solvent spectrophotometrically. the average equilibrium constant values for the systems studied shows the following acceptor trend of tin(iv) in the triorganotin chlorides: p-tolyl > ...
Donor-Acceptor Stenhouse Adducts (DASAs) are molecular photoswitches that reversibly isomerize from a linear to cyclized form upon visible light irradiation. In the form, these molecules selectively react with thiol in thiol-Michael addition. Driven by complexity of switching mechanism and chemical properties DASAs, effect concentration (ranging 1 5 mM DASA) on addition was investigated. We fin...
In this research dense fluid discharge was experimentally investigated under the surface jet in the shallow acceptor. The investigated parameters were depth of the acceptor ambient, flow rate and the concentration of surface jet. In order to investigate the relationship between these parameters, a physical model experiments were performed in the hydraulic laboratory of Shahid Chamran University...
in this paper, the electronic eigenstates and energy spectra of single and two-interacting electrons confined in a concentric double quantum rings with a perpendicular magnetic field in the presence of on-center donor and acceptor impurities are calculated using the exact diagonalization method. for a single electron case, the binding energy of on-center donor and acceptor impurities ar...
