title: Brevicompanine C, cyclo-(D-Ile-L-Trp), and cyclo-(D-Leu-L-Trp), plant growth regulators from Penicillium brevi-compactum.
abstract: New plant growth regulators, named brevicompanine C (1), cyclo-(D-Ile-L-Trp) (2), and cyclo-(D-Leu-L-Trp) (3), have been isolated from Penicillium brevi-compactum Dierckx, and their structures have been established by spectroscopic methods including 2D NMR and chiral TLC analysis. Plant growth activities of 1, 2, and 3 have been examined using lettuce seedling bioassay methods. All compounds accelerated the root growth of the seedlings in proportion to their concentration from 1 to 100 mg/L.
