Paragraph 0047; 0054-0056, (2018/04/28)
The invention discloses a novel 3,5-di-substituted 1H-indole derivative and synthesis and application thereof. The structural formula of the novel 3,5-di-substituted 1H-indole derivative is shown in formula 11, in the formula, R is selected from halogen, C1-C6 methyl, C1-C6 methoxyl, -OH, -COOH, -SO3H or -SO2NH2. The invention further provides a method for preparing the compound. The method has eight steps, the reaction yield of every step is higher than 60%, the reaction yields of four of the eight steps are higher than 90%, and the purities of all compounds are greater than 95%, and conformto purity required for later-period anti-tumor cell activity test. The prepared compound 11a-11h has good inhibition activity to pancreatic cell lines BxPC-3, wherein the activity of the compound as shown in formula 11 e is the best, IC50 reaches up to 2.28 mu mol/L, and the compound hardly has toxic or side effects to normal cells of people.

[Figure Presented] In the lead: The title method for the identification of ligands is particularly useful for binding sites where little or no structural information is available. In a fragment-based approach, a suitable pair of first- and second-site ligands is identiled by NMR experiments. By applying a receptor-mediated in situ combinatorial approach, the two ligands are then linked to generate a new high-affinity lead structure (see picture).
