A Three-Component 1,3-Dipolar Cycloaddition Reaction of Azomethine Ylide for Synthesis of New Bis-spiro-oxindolo(pyrrolizidines/pyrrolidines) Derivatives
The development of multicomponent reactions (MCRs) designed to produce elaborate biologically active compounds has become an important area of research in organic, combinatorial, and medicinal chemistry. A comparative study of the synthesis of new bis-spiro-oxindolo(pyrrolizidines/pyrrolidines) ring systems by the cycloaddition of azomethine ylides generated by a decarboxylative route from sarc...
متن کاملTriaryl pyrazoline compound inhibits flavivirus RNA replication.
Triaryl pyrazoline {[5-(4-chloro-phenyl)-3-thiophen-2-yl-4,5-dihydro-pyrazol-1-yl]-phenyl-methanone} inhibits flavivirus infection in cell culture. The inhibitor was identified through high-throughput screening of a compound library using a luciferase-expressing West Nile (WN) virus infection assay. The compound inhibited an epidemic strain of WN virus without detectable cytotoxicity (a 50% eff...

متن کامل1-Acetyl-3-(4-chlorophenyl)-5-(4-fluorophenyl)-2-pyrazoline
In the title mol-ecule, C(17)H(14)ClFN(2)O, the mean plane of the pyrazoline ring makes dihedral angles of 18.19 (1) and 83.51 (4)° with the 4-chloro-benzene and 4-fluoro-benzene rings, respectively. The two benzene rings make a dihedral angle of 76.11 (2)°. Weak inter-molecular C-H⋯O hydrogen bonds help stabilize the crystal structure.
متن کاملSynthesis and Anti-inflammatory Activity of Some 3, 5-Diaryl-2-Pyrazoline Derivatives
Eleven new 3-(4-bromophenyl)-5-(4-fluorophenyl)-2-pyrazoline derivatives 4-9 and 11-15 were synthesized by using 1-(4-bromophenyl)-3-(4-fluorophenyl) prop-2-en-1-one (3). The newly synthesized compounds were evaluated for anti-inflammatory activity against carrageenan edema in albino rats at a dose of 10 mg/kg. All the compounds of this series showed promising anti-inflammatory activity. The mo...
