Abstract

This invention relates to a macrostructure that includes an antiparallel coiled-coil structure shown below or a parallel coiled-coil structure shown below and described in the present application.

First claim

What is claimed:

1. A macrostructure comprising:
(i) an antiparallel coiled-coil structure of formula:

wherein:
each ◯ and each ⊗ is independently absent or a modified or unmodified amino acid residue or analogue thereof, with the proviso that ten to thirty contiguous amino acid residues/analogues are present in each coil, wherein
a, b, c, d, e, f, g, a′, b′, c′, d′, e′, f′, and g′ indicate the location of the amino acid residues/analogues within the coiled-coil structure and

each ⊗ amino acid residue is a modified or unmodified amino acid selected from the group consisting of cysteine, homocysteine, selenocysteine, leucine, isoleucine, hexafluoroleucine, valine, hexafluorovaline, allylglycine, threonine, and analogues of each of the preceding residues;
each is absent or a covalent linker (Linker) between two amino acid residues/analogues, wherein:
each Linker A is independently a linker between a g* amino acid residue and a g′* amino acid residue, wherein the length of the linker is such that the spatial distance between the Cα position of the g* amino acid residue and the Cα position of the g′* amino acid residue is 10-25 Å;
each Linker D is independently a linker between an e* amino acid residue and an e′* amino acid residue, wherein the length of the linker is such that the spatial distance between the Cα position of the e* amino acid residue and the Cα position of the e′* amino acid residue is 10-25 Å;
and

at least one Linker A or Linker D is present;

each

is a point of attachment from a terminal nitrogen to H, —PG 1 , —C(O)R, —C(O)NR 2 , —C(O)NH 2 , —R, —C(O)OR, an amino acid, a peptide, a tag, or a targeting moiety, where each R is independently hydrogen, an alkyl, an alkenyl, an alkynyl, a cycloalkyl, an aryl, a heteroaryl, a heterocyclyl, an arylalkyl, a peptide, a targeting moiety, or a tag; and wherein PG 1 is a protecting group for protection of an amine; and
each

is a point of attachment from a terminal carbonyl to H, —OPG 2 , —NPG 2 , —OR, —OH, —NR 2 , —NH 2 , —NRC(O)C 1-6 alkyl, —NHC(O)C 1-6 alkyl, an amino acid, a peptide, a tag, or a targeting moiety, where each R is independently hydrogen, an alkyl, an alkenyl, an alkynyl, a cycloalkyl, an aryl, a heteroaryl, a heterocyclyl, an arylalkyl, a peptide, a targeting moiety, or a tag; and wherein PG 2 is a protecting group for protection of a carboxylic acid;
or (ii) a parallel coiled-coil structure of formula:

wherein:
each ◯ and each ⊗ s independently absent or a modified or unmodified amino acid residue or analogue thereof, with the proviso that ten to thirty contiguous amino acid residues/analogues are present in each coil, wherein
a, b, c, d, e, f, g, a′, b′, c′, d′, e′, f′, and g′ indicate the location of the amino acid residues/analogues within the coiled-coil structure and
each ⊗ amino acid residue is a modified or unmodified amino acid selected from the group consisting of cysteine, homocysteine, selenocysteine, leucine, isoleucine, hexafluoroleucine, valine, hexafluorovaline, allylglycine, threonine, and analogues of each of the preceding residues;

each is absent or a covalent linker (Linker) between two amino acid residues/analogues, wherein:
each Linker E is independently a linker between a g* amino acid residue and an e′* amino acid residue, wherein the length of the linker is such that the spatial distance between the Cα position of the g* amino acid residue and the Cα position of the e′* amino acid residue is 10-25 Å;
each Linker H is independently a linker between an e* amino acid residue and a g′* amino acid residue, wherein the length of the linker is such that the spatial distance between the Cα position of the e* amino acid residue and the Cα position of the g′* amino acid residue is 10-25 Å; and
at least one Linker E or Linker H is present; and

each

is a point of attachment from a terminal nitrogen to H, —PG 1 , —C(O)R, —C(O)NR 2 , —C(O)NH 2 , —R, —C(O)OR, an amino acid, a peptide, a tag, or a targeting moiety, where each R is independently hydrogen, an alkyl, an alkenyl, an alkynyl, a cycloalkyl, an aryl, a heteroaryl, a heterocyclyl, an arylalkyl, a peptide, a targeting moiety, or a tag; and wherein PG 1 is a protecting group for protection of an amine; and
each

is a point of attachment from a terminal carbonyl to H, —OPG 2 , —NPG 2 , —OR, —OH, —NR 2 , —NH 2 , —NRC(O)C 1-6 alkyl, —NHC(O)C 1-6 alkyl, an amino acid, a peptide, a tag, or a targeting moiety, where each R is independently hydrogen, an alkyl, an alkenyl, an alkynyl, a cycloalkyl, an aryl, a heteroaryl, a heterocyclyl, an arylalkyl, a peptide, a targeting moiety, or a tag; and wherein PG 2 is a protecting group for protection of a carboxylic acid.

2. The macrostructure of claim 1 , wherein each Linker is independently selected from the group consisting of alkylene, alkenylene, arylene, heteroarylene, ethers, thioethers, amides, maleimides, esters, disulfides, diselenides, —O—, —S—, —Se—, and any combination thereof.
