A series of 4-(2-fluorophenoxy)quinoline derivatives containing an acylhydrazone moiety were designed, synthesized and evaluated for their in vitro biological activities against c-Met kinase and five cancer cell lines (A549, H460, HT-29, MKN-45, and U87MG). Most compounds showed weak to excellent antiproliferative activity. The most promising analog, 40 (c-Met IC50 Combining double low line 1.86 nM), displayed 1.3-, 6.8-, 1.5-, 3.5-fold increase against HT-29, H460, A549 and U87MG cell lines, respectively, compared with Foretinib. An analysis of structure-activity relationships revealed that an acylhydrazone scaffold with an unsubstituted sp2 hybridized carbon adjacent to the 4-CF3 phenyl ring is favorable for antitumor activity.

Chiral phenoxypropionates having halogenated 2,5-diphenylpyrimidine cores were synthesized and the effect of a halogeno-substituent on the physical properties such as mesomorphic behavior, spontaneous polarization (Ps) and response time (τ) were investigated.The introduction of a halogen atom to the phenyl ring of 2,5-diphenylpyrimidine core led to a decrease in the thermal stability of mesophases.The Ps values in the achiral host liquid crystal mixture were increased by introducing the halogen atom.However, response times were not improved. - Keywords: ferroelectric liquid crystal, phenoxypropionate, halogeno-substituent
