Synthesis and Spectroscopic Studies of Model Red Fluorescent Protein Chromophores
摘要:
Here we describe the synthesis and spectroscopic characterization of two compounds designed to model the chromophore in DsRed, a red fluorescent protein. Comparison with model green fluorescent protein (GFP) chromophores indicates that the additional conjugation in the DsRed models can account, in part, for the red-shifted absorption and emission properties of DsRed compared to those of GFP. In contrast to the GFP models, the DsRed models are fluorescent with quantum yields of 0.002-0.01 in CHCl3.
Forty-one new focal adhesion kinase (FAK) covalentinhibitors were designed and synthesized based on FAK inhibitor TAE226. Compound 11w displayed the highest inhibition of FAK with an IC50 value of 35 nM and exhibited potent anticancer activity against Hela, HCT116 and MDA-MB-231 cell lines with IC50 values of 0.41, 0.01 and 0.11 μM respectively, compared to TAE226 (2.68, 0.64 and 4.19 μM respectively)
