Nikkomycin
Nikkomycins are a group of antifungal medications. They work by interfering with the building of the fungal cell wall which results in the fungal cell breaking open. They were discovered in 1976. The specific agent nikkomycin Z has weak activity against ''Aspergillus fumigatus'' which may be of benefit when used with other medications, such as caspofungin, ranconazole and amphotericin B, fluconazole or itraconazole Itraconazole, sometimes abbreviated ITZ, is an antifungal medication used to treat a number of fungal infections. This includes aspergillosis, blastomycosis, coccidioidomycosis, histoplasmosis, and paracoccidioidomycosis. It may be given .... Nikkomycin Z also inhibits growth of '' Batrachochytrium dendrobatidis'', a serious fungal pathogen linked to global amphibian declines, while lower concentrations of Nikkomycin Z enhanced natural amphibian antimicrobial skin peptide effectiveness ''in vitro''. Originally identified from '' Streptomyces tendae'', the ni ...

Antifungal Medication
An antifungal medication, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis (thrush), serious systemic infections such as cryptococcal meningitis, and others. Such drugs are usually obtained by a doctor's prescription, but a few are available over the counter (OTC). The evolution of antifungal resistance is a growing threat to health globally. Routes of administration Ocular Indicated when the fungal infection is located in the eye. There is currently only one ocular antifungal available: natamycin. However, various other antifungal agents could be compounded in this formulation. Intrathecal Used occasionally when there's an infection of the central nervous system and other systemic options cannot reach the concentration required in that region for therapeutic benefit. Example(s): amphotericin B. Vaginal This may be used to treat some fungal infec ...

Aspergillus Fumigatus
''Aspergillus fumigatus'' is a species of fungus in the genus ''Aspergillus'', and is one of the most common ''Aspergillus'' species to cause disease in individuals with an immunodeficiency. ''Aspergillus fumigatus'', a saprotroph widespread in nature, is typically found in soil and decaying organic matter, such as compost heaps, where it plays an essential role in carbon and nitrogen recycling. Colonies of the fungus produce from conidiophores; thousands of minute grey-green conidia (2–3 μm) which readily become airborne. For many years, ''A. fumigatus'' was thought to only reproduce asexually, as neither mating nor meiosis had ever been observed. In 2008, ''A. fumigatus'' was shown to possess a fully functional sexual reproductive cycle, 145 years after its original description by Fresenius. Although ''A. fumigatus'' occurs in areas with widely different climates and environments, it displays low genetic variation and a lack of population genetic differentiation on a global s ...

Caspofungin
Caspofungin ( INN; brand name Cancidas) is a lipopeptide antifungal drug from Merck & Co., Inc. It is a member of a class of antifungals termed the echinocandins. It works by inhibiting the enzyme (1→3)-β-D-glucan synthase and thereby disturbing the integrity of the fungal cell wall. Caspofungin was the first inhibitor of fungal (1→3)-β-D-glucan synthesis to be approved by the United States Food and Drug Administration. Caspofungin is administered intravenously. It is on the World Health Organization's List of Essential Medicines. Medical uses Caspofungin acetate for injection was initially approved by both the US Food and Drug Administration (FDA), and the European Medicines Agency (EMA) in 2001. Its approved therapeutic indications by both organizations include the empirical therapy of presumed fungal infections in febrile, neutropenic adults and for salvage therapy in people treatment of invasive aspergillosis in adults whose disease is refractory to, or who ar ...

Amphotericin B
Amphotericin B is an antifungal medication used for serious fungal infections and leishmaniasis. The fungal infections it is used to treat include mucormycosis, aspergillosis, blastomycosis, candidiasis, coccidioidomycosis, and cryptococcosis. For certain infections it is given with flucytosine. It is typically given intravenously. Common side effects include a reaction with fever, chills, and headaches soon after the medication is given, as well as kidney problems. Allergic symptoms including anaphylaxis may occur. Other serious side effects include low blood potassium and myocarditis (inflammation of the heart). It appears to be relatively safe in pregnancy. There is a lipid formulation that has a lower risk of side effects. It is in the polyene class of medications and works in part by interfering with the cell membrane of the fungus. Amphotericin B was isolated from '' Streptomyces nodosus'' in 1955 at the Squibb Institute for Medical Research from cultures ...

Fluconazole
Fluconazole is an antifungal medication used for a number of fungal infections. These include candidiasis, blastomycosis, coccidioidomycosis, cryptococcosis, histoplasmosis, dermatophytosis, and tinea versicolor. It is also used to prevent candidiasis in those who are at high risk such as following organ transplantation, low birth weight babies, and those with low blood neutrophil counts. It is given either by mouth or by injection into a vein. Common side effects include vomiting, diarrhea, rash, and increased liver enzymes. Serious side effects may include liver problems, QT prolongation, and seizures. During pregnancy it may increase the risk of miscarriage while large doses may cause birth defects. Fluconazole is in the azole antifungal family of medication. It is believed to work by affecting the fungal cellular membrane. Fluconazole was patented in 1981 and came into commercial use in 1988. It is on the World Health Organization's List of Essential M ...

Itraconazole
Itraconazole, sometimes abbreviated ITZ, is an antifungal medication used to treat a number of fungal infections. This includes aspergillosis, blastomycosis, coccidioidomycosis, histoplasmosis, and paracoccidioidomycosis. It may be given by mouth or intravenously. Common side effects include nausea, diarrhea, abdominal pain, rash, and headache. Severe side effects may include liver problems, heart failure, Stevens–Johnson syndrome and allergic reactions including anaphylaxis. It is unclear if use during pregnancy or breastfeeding is safe. It is in the triazole family of medications. It stops fungal growth by affecting the cell membrane or affecting their metabolism. Itraconazole was patented in 1978 and approved for medical use in the United States in 1992. It is on the World Health Organization's List of Essential Medicines. Recent research works suggest itraconazole (ITZ) could also be used in the treatment of cancer by inhibiting the hedgehog pathway in a ...

Chitin Synthase
In enzymology, a chitin synthase () is an enzyme that catalyzes the chemical reaction :UDP-N-acetyl-D-glucosamine + ,4-(N-acetyl-beta-D-glucosaminyl) \rightleftharpoons UDP + ,4-(N-acetyl-beta-D-glucosaminyl)+1 Thus, the two substrates of this enzyme are UDP-N-acetyl-D-glucosamine and ,4-(N-acetyl-beta-D-glucosaminyl), whereas its two products are UDP and ,4-(N-acetyl-beta-D-glucosaminyl)+1. This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-N-acetyl-D-glucosamine:chitin 4-beta-N-acetylglucosaminyl-transferase. Other names in common use include chitin-UDP N-acetylglucosaminyltransferase, chitin-uridine diphosphate acetylglucosaminyltransferase, chitin synthetase, and trans-N-acetylglucosaminosylase. This enzyme participates in aminosugars metabolism. Production Chitin Synthase is manufactured in the rough endoplasmic reticulum of fungi as the inactive form, zymogen. The zym ...
