Title:
USE OF BIS-IMINOBIOTIN COMPOUND FOR DRUG DELIVERY PURPOSES
Document Type and Number:
WIPO Patent Application WO/2019/189867
Kind Code:
A1
Abstract:
The technical problem of the present invention is to provide a bis-iminobiotin compound which has a structure that enables the easy bonding of a bis-iminobiotin moiety to a drug or a fluorescent compound and is useful for the delivery of a drug to a streptavidin-labeled substance. The bis-iminobiotin compound that can solve the technical problem of the present invention is represented by general formula 9. (In the formula, A, D and E independently represent a spacer capable of bonding two bicyclo rings to each other, wherein E represents a structure that may be branched, each of A, D and E may have a substituent, and A, D and E may together form a cyclic structure; J represents a functional group for achieving a click reaction; G represents a spacer capable of bonding E to J; and R represents a hydrogen atom, an acetyl group, a benzyl group, a trifluoroacetyl group or a Boc group.)
