Generic Name
Hydroxystilbamidine
DrugBank Accession Number
DB14753
Background

Hydroxystilbamidine isethionate is used in the therapy of some patients with nonprogressive blastomycosis of the skin, and pulmonary or systemic blastomycosis in children, with fewer side effects than amphotericin B. Hydroxystilbamidine isethionate is also used in pathology for diagnostic purposes.

Pharmacodynamics

Hydroxystilbamidine isethionate is a member of the diamidines, a large family of biochemially and pharmacologically interesting compounds. It has a rather unusual combination of properties, exhibiting antitrypanosomal, antimaliarial, antifungal and carcinostatic activities. It also appears to act as an immunosuppressant. This drug may be used in the treatment of blastomycosis, a disease cased by the dimorphic fungus or mold called Blastomyces dermatitids. Blastomycosis is a pulmonary infection that can lead to fever, cough and (rarely) symptoms similar to tuberculosis. Hydroxystilbamidine has largely been replaced with amphotericin B.

Mechanism of action

Hydroxystilbamidine isethionate (HSB) acts on extracellular DNA and lysosomes. In Trypanosomes there is extensive and selective binding of HSB to the kinetoplastic DNA. This inhibits cell division and reproduction. In yeast there is evidence of binding to extranuclear DNA causing numerous mutations. HSB is also taken up in the lysosomes and leads to a significant increase in the number of lysosome-like bodies and secretion granules in trypanosomal organisms. HSB may also stabilize lysosomal membranes. HSB has also been found to bind RNA and is a powerful inhibitor of cellular ribonucleases.

Actions

DNA is the molecule of heredity, as it is responsible for the genetic propagation of most inherited traits. It is a polynucleic acid that carries genetic information on cell growth, division, and function. DNA consists of two long strands of nucleotides twisted into a double helix and held together by hydrogen bonds. The sequence of nucleotides determines hereditary characteristics. Each strand serves as the template for subsequent DNA replication and as a template for mRNA production, leading to protein synthesis via ribosomes.
