Abstract: Provided are methods of treating a disease or condition characterized by a deficiency of or a defect in an iron transporter using a small molecule. For example, the method may increase transepithelial iron transport, or it may increase iron release. Additionally, the small molecule may be hinokitiol, or it may be selected from the group consisting of amphotericin B, calcimycin, nonactin, deferiprone, purpurogallin, and maltol. Also provided is a method of identifying a compound capable of treating a disease or condition characterized by a deficiency of or a defect in an iron transporter.

Abstract: Disclosed are analogues of hinokitiol, methods for preparing them, and pharmaceutical compositions thereof. Also disclosed are methods for their use in treating iron-related diseases.

Abstract: Disclosed are methods for treating a disease or condition characterized by decreased expression or reduced function of an ion channel, comprising administering to a subject in need thereof a therapeutically effective amount of a pore-forming polyene macrolide or pore-forming derivative thereof. For example, the pore-forming polyene macrolide may be amphotericin B (AmB), nystatin, or natamycin. The methods can be used to treat cystic fibrosis.

Abstract: Disclosed are methods of treating a disease or condition characterized by a deficiency of or a defect in a copper transporter using a small molecule. For example, the method may increase copper transport, or it may increase copper release. Additionally, the small molecule may be hinokitiol, or it may be selected from the group consisting of amphotericin B, calcimycin, nonactin, deferiprone, purpurogallin, and maltol. Also provided is a method of identifying a small molecule capable of treating a disease or condition characterized by a deficiency of or a defect in a copper transporter.
