Tubulin is the target of many anticancer drugs, including N-phenyl-N'-(2-chloroethyl)urea (CEU). Unlike most anti-beta-tubulin agents, CEUs are protein monoalkylating agents binding through their N'-(2-chloroethyl)urea moiety to an amino acid nearby the colchicine-binding site on beta-tubulin isoform-2. Following the previously synthesized and attractive N-(3-omega-hydroxyalkylphenyl)-N'-(2-chloroethyl)urea

coupling reactions of alkynes and a variety of aryl halides with 1,3‐bis(5‐ferrocenylisoxazoline‐3‐yl)benzene as an efficient non‐phosphorusligand under copper‐free conditions are presented. The main advantages over previous methodologies include low catalyst loading (0.2 mol% Pd(OAc)2 and 0.4 mol% ferrocenyl bisoxazoline ligand are sufficient for these coupling reactions), less problematic reaction medium
demonstrating the value of this transcription factor for the development of novel anti-cancer therapies. We report herein the design, synthesis and biologicalevaluation of LM98, a flufenamic acid analogue. LM98 shows strong affinity to TEAD, inhibits its autopalmitoylation and reduces the YAP-TEAD transcriptional activity. Binding of LM98 to TEAD was supported by 19F-NMR studies while co-crystallization

:An efficient method for the Sonogashiracouplingreaction between aryl halides and terminalalkynes has been developed. The reaction was performed in ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim][BF4]) under microwave irradiation. High yields ofproducts were obtained in a very short reaction time. Moreover, the medium and catalyst could berecovered and reused three times without
