Selective induction of secondary metabolism in Phaseolus lunatus by 6-substituted indanoyl isoleucine conjugates
摘要:
A novel and highly efficient route to new indanoyl isoleucine conjugates is described, which allows a wide range of substituents to be attached to the 6-position of the indanoyl moiety. We report the synthesis of conjugates with methyl, methoxy, propoxy, allyloxy, pentoxy, and 2-(2-methoxy-ethoxy)-ethoxy 6-position substituents. Preliminary biological activities of the novel compounds with significantly enhanced water solubility were determined using the Lima bean (Phaseolus lunatus) volatile bioassay. The compounds induce variable volatile patterns, and structure-activity relationships show an ability to differentially induce separate pathways leading to secondary metabolites.

Described are 6-substituted indanoyl amino acid conjugates of the chemical Formula (I) wherein R1= (II), R2 R5 have the meanings given in the description, and X = a halogen atom; as potent plant elicitors and efficient mimics of the phytotoxin coronatine. Also, processes for producing the improved elicitors are provided, which allow a rapid and convenient access to large quantities of the highly active compounds. Furthermore, there are compositions and plant protecting agents described, comprising as active ingredient a compound of the present invention. The plant protecting agents are useful for inducing resistance to pathogens in plants. The compositions may also be used to selectively induce senescence in fruit of plants.
