Synthesis and in vitro Antibacterial Activity of Some Novel 2-Amino-4, 6-D Derivatives
Heterocyclic systems are one of the most important classes of organic compounds present in nature or synthesized in laboratory. These compounds posses an array of biological activities and are employed in the treatment of commonly occurring diseases. Keeping this in view, some new 2-amino-4,6-diarylpyrimidine from chalcones were synthesized. Eight novel 2-amino-4,6-diarylpyrimidine derivatives ...

It is probably very hard to develop a new model checker that is faster than UPPAAL for verifying (correct) timed automata. In fact, our tool MCTA does not even try to compete with UPPAAL in this (i. e., UPPAAL’s) arena. Instead, MCTA is geared towards analyzing incorrect specifications of timed automata. It returns (shorter) error traces faster.

متن کاملSynthesis and Biological Evaluation of 4-hydroxychromenyl arylmethyl-6-hydroxy pyrimidine-2, 4-dione Derivatives
Background: An efficient, promoted tri-component catalytic reaction between barbituric acid (or N,N-dimethyl barbituric acid), 4-hydroxy coumarin, and a wide range of aryl aldehydes using zinc oxide nanowires (ZnO NWs) to obtain some new 4-hydroxychromenylarylmethyl-6-hydroxypyrimidine-2,4-diones is described. Method: The reactants were successfully condensed ...
متن کاملSlow photoelectron velocity-map imaging spectroscopy of C(2)N(-), C(4)N(-), and C(6)N(-).
High resolution photoelectron spectra of C(2)N(-), C(4)N(-), and C(6)N(-) anions are reported, obtained using slow electron velocity-map imaging. The spectra show well resolved transitions to the X (2)Pi neutral ground state of all three species and to the a (4)Sigma(-) excited state of C(2)N and C(4)N. This study yields the adiabatic electron affinity of C(2)N, C(4)N, and C(6)N, the spin-orbit...
