Novel Compounds and Methods for Treating Invasive Fungal Infections

Compounds that decrease the synthesis of glucosylceramide, a sphingolipid that promotes fungal infection

Background:

With the increasing number of immunodeficient subjects and the increase of the lifespan of these subjects due to the advance in medicine, there has been a concomitant rise in the number of cases of life-threatening fungal infections. Current antifungals are either static, toxic or/and with a too narrow spectrum of activity and increased use have led to increased drug resistance. Therefore, there is a need for new, safer and more effective compounds. Studies have shown that a fungal sphingolipid, glucosylceramide (GlcCer), is critical in promoting fungal virulence and is involved in the infectious processes of a variety of human pathogenic fungi.

Technology Overview:

Researchers at Stony Brook University identified compounds that significantly decrease the synthesis of GlcCer in C. neoformans but not in mammalian cells. These compounds are effective in vitro against a series of pathogenic fungi, protect mice from Cryptococci meningitis, invasive candidiasis and significantly decrease lung burden of P. murina, the murine model of human pneumocystosis.
