Have a little heart: A screen for mesoderm inducing chalcones in humanpluripotentstemcell cultures identified 4’-hydroxychalcone (4’HC) as an effective replacement for bone-morphogenetic protein 4 (BMP4) in supporting the derivation of engineered heartmuscle (EHM)-formation competent cardiomyocytes.

New unsymmetrical 2[2(4)]-mono-and tri (substituted tri)-methine cyaninedyes incorporating 1,2,5,6-tetrahydro-4,6-diaryl pyrimidine (pyrimidinium-1-yl salt)-2-one were prepared. Structural determination was carried out by elemental analysis, IR and 1H NMR spectral data. The spectral behaviour of all the synthesized cyanines was examined in 95% ethanol.

(15) showed significant cytotoxicities. The most effective compound was 15, which showed high cytotoxic activity with an IC50 value lower than 1 μg/ml, and no selectivity on the tumor cells evaluated. Substituents at C(4) of ring B were found to be essential for cytotoxicity. In addition, it was also demonstrated that some of these chalcones are moderate inhibitors of cathepsinK and have no activity
group which is liable for the antimicrobial activity of the chalcone is additionally of vast use in further chemical modification into a variety of heterocyclic compounds. A new series of chalcone derivatives was synthesized and characterized by spectral analysis (IR, 1H-NMR, 13C-NMR, MS and elemental analysis) and evaluated for its in vitro antimicrobial activity against bacterial (Gram negative and Gram

conjugated system’s carbonyl group was attributed to high, low, or even no conductivity for all phenolic polymers since the electronic effects (inductive and mesomeric) could impact the polarization of the carbonyl group and, consequently, change the degree of the charge separation to show varied conductivity values.
