- Ketoconazole topical (Nizoral)
- Miconazole topical (Monistat)
- Oxiconazole 1% cream (Oxistat)

How do you synthesis imidazole?
The Van Leusen Imidazole Synthesis allows the preparation of imidazoles from aldimines by reaction with tosylmethyl isocyanide (TosMIC). The reaction has later been expanded to a two-step synthesis in which the aldimine is generated in situ: the Van Leusen Three-Component Reaction (vL-3CR).
What is imidazole used for?
The imidazole group functions as a nucleophile, or a general base, in the active sites of many enzymes, and may bind metal ions. Histidine is nonessential in adults but is essential in the diet of infants and individuals with uremia (a kidney disorder).
What are imidazole derivatives?
Many imidazole-based derivatives have been marketed as antifungal drugs such as ketoconazole (1), miconazole (2), clotrimazole (3), tioconazole (4), econazole (5), tinidazole (6), enilconazole/imazalil (7), parconazole (8), eberconazole (9), lanoconazole (10), fenticonazole (11), bifonazole (12), sulconazole (13).
What is the mechanism of action of Echinocandins?
The echinocandins have a unique mechanism of action, inhibiting beta-(1,3)-D-glucan synthase, an enzyme that is necessary for the synthesis of an essential component of the cell wall of several fungi. The echinocandins display fungistatic activity against Aspergillus spp.
What is the mechanism of action for nystatin?
Mechanism of action Like amphotericin B and natamycin, nystatin is an ionophore. It binds to ergosterol, a major component of the fungal cell membrane. When present in sufficient concentrations, it forms pores in the membrane that lead to K+ leakage, acidification, and death of the fungus.
What is the chemical formula of imidazole?
C3H4N2
Imidazole/Formula

What is the target of imidazole?
Imidazoles alter the cell membrane permeability of susceptible yeasts and fungi by blocking the synthesis of ergosterol (demethylation of lanosterol is inhibited), the primary cell sterol of fungi. The enzyme targeted is a fungal cytochrome P450 (CYP450).
What is the chemical structure of imidazole?

What is the mechanism of action of imidazole?
Mode of Action: Imidazoles alter the cell membrane permeability of susceptible yeasts and fungi by blocking the synthesis of ergosterol (demethylation of lanosterol is inhibited), the primary cell sterol of fungi. The enzyme targeted is a fungal cytochrome P450 (CYP450).
What do echinocandins do?
Echinocandins are a class of antifungal drugs that target the fungal cell wall. They are lipopeptide molecules that noncompetitively inhibit (1,3) beta-d-glucan synthase enzyme. This enzyme forms glucan, a major component of the fungal cell wall therefore by inhibiting its synthesis fungal cell walls are damaged.
Which is the best method for the synthesis of imidazoles?
The preparation of (27) 2- mercaptoimidazoles from (25) a- amino ketones or aldehyde and (26) potassium thiocyanate or alkylisothiocyanates is a common method for the synthesis of imidazoles. The sulphur can readily be removed by a variety of oxidative method to give the desired imidazoles.
What’s the difference between an imidazole and a parent compound?
Imidazole (1) refers to the parent compound,whereas imidazoles are a class of heterocyclic with similar ring structure, but varying substituents. This ring system is present in important biological building blocks, such as histidine (2), and the related hormone histamine (3).
How is the reactivity of benzimidazole related to its reactivity?
The overall reactivity of imidazoles and Benzimidazole is referred from sets of resonance structure in which the dipolar contributors have finite importance. These predict electrophilic attack in imidazole at N-3 or any ring carbon atom, nucleophilic attack at C-2 or C-1 and also the amphoteric nature of the molecule.
Are there any drugs that contain an imidazole ring?
Many drugs contain an imidazole ring, such as antifungal drugs and Nitroimidazole (4). [7-11] Imidazole is a monoacidic base having the ability to form crystalline salts with acids. The melting point of number of characteristic imidazolium salts [12].
