A range of analogues of the natural germination stimulant, strigol, for parasitic weeds of the genera Striga and Orobanche, has been prepared. Most of the products contain an α-formyl-γ-lactone (or α-formyl-γ-lactam) grouping attached through an enol-ether linkage to the 5-position of a but-2-enolide. Some have shown sufficiently high activities as to warrant large-scale field trials.

The present invention relates to, inter alia, extracellular drug conjugates (EDC) in which an antibody or other targeting agent (e.g. a targeting moiety) is linked to a drug through a linker (e.g. a non-cleavable linker). These conjugates are useful in the treatment of disease and/or as a tool in the evaluation of biological systems.
