Figure 2. Synthesis of tivantinib enantiomers and analogues.
(A) Synthetic strategy and chemical structures of (−)-tivantinib (8), its enantiomer (+)-tivantinib (7) and their coupleable analogues, (9) and (10), respectively. For the full synthetic route see Figure S1A. (B) Differential inhibition of cellular viability of A549 and H1648 cells by (−)-tivantinib and (+)-tivantinib.
