Herein we report the synthesis of new probes for photoaffinity labeling with the aim of receptor identification and mode of action elucidation of 3,4,5-trimethylfuran-2(5H)-one (TMB), recently identified in the smoke of burning vegetation as an efficient seed germination inhibitor. These photoaffinity probes consist of an ethynyl group that acts as a tag for introduction of an optional detectable marker unit by an appropriate chemoselective ligation method after the photo-cross-linking operation.

Paragraph 0123-0125, (2021/05/21)
Disclosed is a bis-imide compound comprising two or more aryl moieties substituted with ethynyl moieties and the two or more aryl moieties each having one or more polar substituents. Further disclosed is a polymer composition comprising a copolymer polymerized from a monomer mixture of (a) one or more first monomers comprising a bis-imide compound comprising two or more aryl moieties substituted with ethynyl moieties and the two or more aryl moieties each having one or more polar substituents; and (b) one or more second monomers comprising two or more cyclopentadienone moieties. The polymer compositions exhibit favorable properties for use in electronics and displays applications.

The preparation of alkyne-modified ansamitocins by mutasynthetic supplementation of Actinosynnema pretiosum mutants with alkyne-substituted aminobenzoic acids is described. This modification paved the way to introduce a thiol linker by Huisgen-type cycloaddition which can principally be utilized to create tumor targeting conjugates. In bioactivity tests, only those new ansamitocin derivatives showed strong antiproliferative activity that bear an ester side chain at C-3.
