Due to pressure from combinatorial chemistry and the streamlining of the drug discovery process through automated high-throughput screening technologies, pharmaceutically based natural products programs are under increasing scrutiny. However by taking advantages of technologies originally developed for high-throughput screening and combinatorial chemistry and applying them to processes considered as bottlenecks in classical natural products chemistry (purification, structure elucidation, sample availability) it is our opinion that natural products can still contribute to the effective discovery of novel bioactive and pharmaceutically relevant metabolites. We describe here several such strategies that if universally implemented, will demonstrate i) whether chemical diversity is truly being accessed, ii) that novel metabolites can be formatted in a manner appropriate for modern screening paradigms, and iii) that natural products can be rapidly identified not only for novelty and pharmaceutical relevance but to assess their true biological origin
