Squalamine(cas 148717-90-2) is an aminosterol compound with potent broad spectrum antimicrobial activity discovered in the tissues of the dogfish shark (Squalus acanthias). The discovery of squalamine in the shark implicates a steroid as a potential host-defense agent in vertebrates and provides insights into the chemical design of a family of broad-spectrum antibiotics.

An important strategy to circumvent the problem of antimicrobial resistance is to
search for new compounds with antimicrobial activity. In this context,
aminosterols, which include squalamine-like compounds and ceragenins, have gained
interest due to their wide spectrum of antibacterial and antifungal properties.
In light of recently reported data, we decided to analyze the mechanism of action
of these compounds as well as their antimicrobial properties. Aminosterols are
active against both bacterial reference strains and multidrug-resistant
antibiotics as they disrupt the integrity of the bacterial membrane. Thus, these
compounds could be useful in the development of new topical decontaminants or

Squalamine lactate inhibits angiogenesis by a long-lived, intracellular mechanism
of action. The drug is taken up into activated endothelial cells through
caveolae, small invaginations in the cellular membrane. Subsequently, the drug
binds to and /chaperones/ calmodulin to an intracellular membrane compartment and
blocks angiogenesis at several levels. A series of basic investigations,
preclinical studies, and human clinical trials have begun to establish the proof
of concept, efficacy, and safety parameters for use of squalamine lactate as a
therapeutic agent for exudative age-related macular degeneration and several
types of malignancies.

The purpose of this mini-review is to summarize and highlight the different
advances in our understanding of the antimicrobial and antiangiogenic activity of
squalamine, a cationic steroid isolated in 1993 from the dogfish shark Squalus
Acanthias. Indeed, squalamine has shown to be useful for the treatment of
important diseases such as cancers (lung, ovarian, brain and others), age-related
macular degeneration (AMD) and the control of body weight in man. All these
results led to a question: could we consider squalamine as a polyvalent drug of
