Miltefosine is an anti-leishmanial agent. It is an alkyl phospholipids compound, was originally intended for breast cancer and other solid tumors. However, it could not be developed as an oral agent because of dose-limiting gastro-intestinal toxicity, and only a topical formulation is approved for skin metastasis. But Miltefosine showed excellent antileishmanial activity both in vitro and in experimental models. Miltefosine is effective in vitro against both promastigotes and amastigotes of various species of Leishmania and also other kinetoplastidae (Trypanosoma cruzi,T. brucei) and other protozoan parasites (Entamoeba histolytica, Acanthamoeba). Mechanism of action is unknown. It is likely to involve interaction with lipids (phospholipids and sterols), including membrane lipids, inhibition of cytochrome c oxidase (mitochondrial function), and apoptosis-like cell death. Miltefosine is approved for the treatment of Visceral leishmaniasis (due to Leishmania donovani), Cutaneous leishmaniasis (due to Leishmania braziliensis, Leishmania guyanensis, and Leishmania panamensis) and Mucosal leishmaniasis (due to Leishmania braziliensis).

Natamycin (Pimaricin, Pimafucin, Natadrops, Natacyn) is a polyene antifungal agent originally isolated from Streptomyces natalensis found in a soil sample from Natal, South Africa. Natamycin was discovered in DSM laboratories in 1955. Similar to other polyenes, natamycin binds to ergosterol in the fungal cell membrane. Natamycin blocks fungal growth by binding specifically to ergosterol with¬out permeabilizing the membrane where it inhibits vacuole fusion at the priming phase and interferes with membrane protein functions. Natamycin is also used in the food industry as an effective preservative. Natamycin is active against most Candida spp. Aspergillus spp., Fusarium spp. and other rarer fungi that cause keratitis. Secondary or acquired resistance is probably rare, but not extensively studied. Natamycin is not effective in vitro against gram-positive or gram-negative bacteria. Topical administration appears to produce effective concentrations of natamycin within the corneal stroma but not in intraocular fluid. Natamycin is poorly soluble in water and not absorbed through the skin or mucous membranes, including the vagina. Very little is absorbed through the gastrointestinal tract. After ocular application, therapeutic concentrations are present within the infected cornea, but not in intra-ocular fluid Natamycin may cause some irritation on skin or mucous membranes

Griseofulvin is a mycotoxic metabolic product of Penicillium spp. It was the first available oral agent for the treatment of dermatophytoses and has now been used for more than forty years. Griseofulvin is fungistatic with in vitro activity against various species of Microsporum Epidermophyton, and Trichophyton. It has no effect on bacteria or on other genera of fungi. Following oral administration, griseofulvin is deposited in the keratin precursor cells and has a greater affinity for diseased tissue. The drug is tightly bound to the new keratin which becomes highly resistant to fungal invasions. Once the keratin-Griseofulvin complex reaches the skin site of action, it binds to fungal microtubules (tubulin) thus altering fungal mitosis. Griseofulvin is fungistatic, however the exact mechanism by which it inhibits the growth of dermatophytes is not clear. It is thought to inhibit fungal cell mitosis and nuclear acid synthesis. It also binds to and interferes with the function of spindle and cytoplasmic microtubules by binding to alpha and beta tubulin. It binds to keratin in human cells, then once it reaches the fungal site of action, it binds to fungal microtubes thus altering the fungal process of mitosis.

Amphotericin B used to treat progressive, potentially life-threatening fungal infections, such as oral thrush, vaginal candidiasis and esophageal candidiasis in patients with normal neutrophil counts. Also, Amphotericin B is often used in otherwise-untreatable protozoan infections such as visceral leishmaniasis and primary amoebic meningoencephalitis. As with other polyene antifungals, amphotericin B binds with ergosterol, a component of fungal cell membranes, forming a transmembrane channel that leads to monovalent ion (K+, Na+, H+ and Cl−) leakage, which is the primary effect leading to fungal cell death. When administered concurrently, the following drugs may interact with amphotericin B: Antineoplastic agents, Corticosteroids and Corticotropin (ACTH); Digitalis glycosides; Flucytosine; Imidazoles (e.g., ketoconazole, miconazole, clotrimazole, fluconazole, etc.); Zidovudine; Skeletal muscle relaxants (tubocurarine); Rifabutin; Leukocyte transfusions. The adverse reactions most commonly observed are: fever; malaise; weight loss; hypotension; tachypnea; anorexia; nausea; vomiting; diarrhea; dyspepsia; cramping epigastric pain; normochromic, normocytic anemia; pain at the injection site with or without phlebitis or thrombophlebitis; generalized pain, including muscle and joint pains; headache; decreased renal function and renal function abnormalities.

There is no information about biological and pharmacological application of Iron(II) fluoride (also known as ferrous fluoride). It is known, that this substance is used to catalyze some organic reactions.

Clotrimazole is an anti-fungal medicine indicated for the treatment of vaginal yeast infections and tinea. It can be used either in combination with other drugs (betamethasone dipropionate) or alone, in form of topical or vaginal cream. The drug exerts its action by inhibiting lanosterol demethylase thereby affecting the growth of fungi.

Ferric Ammonium EDTA Solution is normally used as a photographic chemical for a bleaching agent in the process of colour washing. It is also used as a complexing, and oxidizing agent & as a fertilizer and catalyst. EDTA acid are colourless, water-soluble solid that are widely used to dissolve scale. The usefulness of these ammonium salts arise because of its role as a chelating agent, i.e. its ability to "sequester" metal ions such as Ca2+ and Fe3+.

Senexin B is a selective CDK8/CDK19 inhibitor developed by Senex Biotechnology Inc. Senexin B is an ATP pocket binder, with very high target selectivity as indicated by kinome profiling. CDK8/19 inhibition produces chemopotentiating, chemopreventive and anti-metastatic effects in different types of cancer.
