Utilization of recombinase polymerase amplification method combined with lateral flow dipstick for visual detection of respiratory syncytial virus.

Respiratory syncytial virus (RSV) is a major causative agent of respiratory tract infection necessitating hospitalization in children. A rapid diagnostic method would facilitate early detection of RSV infection and timely implementation of special treatment. Here, a reverse transcription recombinase polymerase amplification (RT-RPA) assay combined with lateral flow dipstick (LFD) was evaluated for rapid visual detection of RSV.

Synthesis and anticancer evaluation of thiazolyl-chalcones.

Thirty-seven (E)-1-(4-methyl-2-arylaminothiazol-5-yl)-3-arylprop-2-en-1-ones were synthesized via Claisen-Schmidt condensation of 1-(4-methyl-2-(arylamino)thiazol-5-yl)ethanone with the corresponding arylaldehydes. All these thiazolyl-chalcones were characterized and evaluated by MTT assay on human cancer cell lines BGC-823, PC-3, NCI-H460, BEL-7402 in vitro. Compounds 5, 8, 26, 37 and 41 are effective against cancer cell lines with IC(50)s below 10 μM.
