High-throughput Natural Product Chemistry Methods and the Application of the Capillary NMR Probe

High-throughput natural product chemistry methods, mainly consisting of two parallel multi-channel systems of preparative HPLC and LC-ELSD-MS, have been applied to the generation and analysis of large natural product libraries. The enhancement on mass sensitivity by the low volume capillary NMR probe (CapNMR^TM) technology makes the NMR data acquisition, structure elucidation and de-replication on microgram amounts of natural products a reality. This state-of-the-art probe has ushered in a new era in the miniaturization of structure elucidation of natural products using mass-limited material. The perspectives for natural products as small molecular probes in brain functional genomics are briefly provided.
