Advances have been made to develop new antifungal agents and to understand the existing ones. Yunjin Lee1, Nicole Robbins1and Leah E. CowenFungal pathogens are a severe public health problem. The leading causative These compounds and the analog BAY, appear to have a dual mode of action. The suggested mechanism of action involves interference with amino acid transport and cellular regulation of amino acid metabolism However, the mechanism of action of most antifungal drugs is targeting ergosterol, an essential component of the fungal cell membrane. The massive emergence offungal diseases associated with AIDS in the s and the rising frequency of fatal mycoses associated with increasing use of immunosup-pressive medical therapies since the s stimulated Molecular mechanisms governing antifungal drug resistance. Instead of ergosterol, the mammalian cell membrane possesses cholesterol. Fungistatic agent: The agent that inhibits The biomedical literature abounds with reports of macro-molecules essential for fungal survival, growth, virulence or cellular The continuing need to develop drugs that treat opportunistic infections (OIs) is related to several factors including the capacity of OIs to cause serious and life threatening The molecular mechanisms include altered drug affinity and target abundance, reduced intracellular drug levels caused by efflux pumps, and formation of biofilms Various mechanisms can lead to acquired resistance of Candida species to azole drugs, the most common being induction of the efflux pumps encoded by the MDR or CDR , · Antifungal drugs are the agents that kill or stop fungal growth and are applied to treat or prevent fungal infections(mycoses). A proper antifungal drug Antifungals can be grouped into three classes based on their site of action: azoles, which inhibit the synthesis of ergosterol (the main fungal sterol); polyenes, which interact with fungal membrane sterols physicochemically; andfluorocytosine, which inhibits macromolecular synthesis describes the targets and mechanisms of action of all classes of antifungal agents in clinical use or with clinical potential. New targets, new agents and clinical realities.
