Abstract
There is provided use of an amino acid derivative in free acid or salt form, in which the nitrogen atoms of two or more amino acid molecules are linked by a hydrocarbyl or substituted hydrocarbyl group, as an anti-fungal compound.
Claims22
A method of preventing fungal growth on a material, the method comprising contacting the material with an amino acid derivative in free acid or salt form, in which the nitrogen atoms of two or more amino acid molecules are linked by a hydrocarbyl or substituted hydrocarbyl group,
- wherein the amino acids are naturally occurring amino acids;
- and
- wherein the amino acid derivative has at least one chiral centre.
A method of preventing fungal growth and bacterial growth on a material, the method comprising contacting the material with an amino acid derivative in free acid or salt form, in which the nitrogen atoms of two or more amino acid molecules are linked by a hydrocarbyl or substituted hydrocarbyl group,
- wherein the amino acids are naturally occurring amino acids;
- and
- wherein the amino acid derivative has at least one chiral centre.
A method of preventing bacterial growth on a material, the method comprising contacting the material with an amino acid derivative in free acid or salt form, in which the nitrogen atoms of two or more amino acid molecules are linked by a hydrocarbyl or substituted hydrocarbyl group, as an anti-bacterial compound,
- wherein the amino acids are naturally occurring amino acids;
- and
- wherein the amino acid derivative has at least one chiral centre with proviso that the amino acid derivative is other than a chelant selected from derivatives of succinic acid, glutaric acid and phosphonic acid.
A method of preventing fungal growth and bacterial growth on a material, the method comprising contacting the material with an amino acid derivative in free acid or salt form, in which the nitrogen atoms of two or more amino acid molecules are linked by a hydrocarbyl or substituted hydrocarbyl group, and wherein the amino acids are naturally occurring amino acids.
A method of preventing fungal growth on a material, the method comprising contacting the material with a composition comprising an amino acid derivative in free acid or salt form, in which the nitrogen atoms of two or more amino acid molecules are linked by a hydrocarbyl or substituted hydrocarbvl group,
- wherein the amino acids are naturally occurring amino acids;
- and
- wherein the amino acid derivative has at least one chiral centre.
A method of preventing fungal growth and bacterial growth on a material, the method comprising contacting the material with a composition comprising an amino acid derivative in free acid or salt form, in which the nitrogen atoms of two or more amino acid molecules are linked by a hydrocarbyl or substituted hydrocarbyl group,
