Pimprinine and streptochlorin are indole natural products produced by many species of organisms, and they are reported to possess a wide range of biological activities, such as anticancer, antiviral, antifungal activity and so on. In this study, three series of pimprinine derivatives or analogs were efficiently synthesized under the optimized methods. Biological assays conducted at Syngenta firstly indicated the pimprinine derivatives or analogs possessed potential herbicidal and insecticidal activity, and this is highlighted by compounds 21g, 21h, 21i, 21j, 21l, 22h, 22i and 23h, they possessed significant biological activity as well as broad spectrum. Meanwhile, compounds with benzothiophene-oxazole core (21h, 22h and 23h), showed effective nematicidal activity in primary screening. Compounds 21g and 21i were identified as the most promising lead structures for further study.

Through a structure-based molecular hybridization strategy, a series of new N-acylhydrazone derivatives containing the benzothiazole and indole based moiety were designed, synthesized and screened for in vitro antiproliferative activity against Hep G2 cancer cell line. One compound (7a) exhibited excellent antiproliferative activity with IC50 values of 0.78 μM against Hep G2. In addition, C-5 substitutions of the indole ring of target compounds might be crucial for their cytotoxic activities. Additionally, the relative configuration of target compounds was confirmed as the E isomer. Further chemical manipulation of derivative 7a can make it possible to obtain new potential antitumor agents.
