Abstract

The invention provided herein presents a novel family of antifouling agents based on hydroxylated and fluorinated compounds.

First claim

1 . A compound comprising at least one 3,4-dihydroxy-L-phenylalanin (DOPA) group and at least one fluorinated carbon group.

2 . The compound according to claim 1 , wherein said at least one fluorinated carbon group is a fluorinated alkyl group.

3 . The compound according to claim 1 , wherein said at least one fluorinated carbon group is perfluorinated.

4 . The compound according to claim 1 , having the general formula A-L-F, wherein A is DOPA, L is a covalent bond or a linker moiety linking A and F, and F is a fluorinated alkyl moiety.

5 . The compound according to claim 4 , wherein the linker is selected from substituted or unsubstituted carbon chain, optionally comprising two or more amino acids.

6 . The compound according to claim 5 , wherein the linker having the general structure

wherein
each * denotes a point of connectivity;
n is between 0 and 40; and
m is between 1 and 40.

7 . A method for preventing or arresting or minimizing or diminishing one or more of the following:
(d) adsorption of organic and/or bio-organic materials to a surface; (b) adsorption of proteins and/or (poly)saccharides and (poly)lipids to a surface; (c) secretion from cells of multi-organism or of micro-organisms onto a surface;
and
(d) adsorption of cells of multi-organism or micro-organisms to a surface,
the method comprising forming a coat of at least one compound according to claim 1 on at least a region of said surface.

8 . A method for inhibiting settling, attachment, accumulation and dispersion of organisms, organism's secretion of an organic and/or bio-organic material on a surface, the method comprising contacting the surface with an effective amount of a formulation comprising a compound according to claim 1 .

9 . A formulation comprising at least one compound according to claim 1 .

10 . A film comprising at least one compound according to claim 1 .

11 . An article or a device comprising at least one surface region coated with a film according to claim 10 .

12 . A compound selected from

13 . A formulation comprising the compound:

14 . A biofouling film comprising the compound:
