Antifungal paints and coatings

Abstract

Antifungal and antibacterial peptides, polypeptides and proteins as antifungal additives for paint and other coatings are disclosed, along with antifungal compositions, and coated surfaces with antifungal properties. Methods of using the coatings for treating and/or inhibiting growth of mold, mildew and other fungi and bacteria on objects such as building materials that are susceptible to such infestation are also disclosed.

1 - 207 . (canceled) 
     
     
         208 . A coating composition comprising:
 an antifungal peptidic agent selected from the group consisting of at least one of SEQ ID NOS 1-10 and variants of SEQ ID NOS 1-10 having one or more functionally equivalent amino acids substituted therein, said substituted amino acids having no more than a +/−2 difference in hydropathic value of the Kyte-Doolittle scale compared to the hydropathic value of the Kyte-Doolittle scale of amino acids in SEQ ID NOS 1-10, wherein chiral amino acids of the peptidic agent are L-amino acids, and wherein said coating is a paint.   
     
     
         209 . The coating composition of  claim 208  having functionally equivalent amino acid substituted sequences having no more than a +/−1 difference in hydropathic value of the Kyte-Doolittle scale relative thereto. 
     
     
         210 . A coating composition comprising:
 an antifungal peptidic agent selected from the group consisting of at least one of SEQ ID NOS 1-10 and variants of SEQ ID NOS 1-10 having one or more functionally equivalent amino acids substituted therein, said substituted amino acids having no more than a +/−2 difference in hydropathic value of the Kyte-Doolittle scale compared to the hydropathic value of the Kyte-Doolittle scale of amino acids in SEQ ID NOS 1-10, wherein said coating is a paint, said paint comprising at least one component selected from the group consisting of titanium dioxide, Bentonite clay, silicate mineral, and acrylic latex.   
     
     
         211 . The coating composition of  claim 210  having functionally equivalent amino acid substituted sequences having no more than a +/−1 difference in hydropathic value of the Kyte-Doolittle scale relative thereto.
