INTRODUCTION
Ciclopirox Olamine (CPO) is the N-oxide of a 2 -hydroxy pyridine derivative that carries antifungal, antibacterial, and anti-inflammatory properties. It is composed of 6-cyclohexyl-1-hydroxy-4-methyl-2(1H)-pyridone combined with 2 aminoethanol (olamine) in a 1:1 ratio. It works through a multifaceted mechanism of action that primarily disrupts the fungal cell’s metabolic function by inhibiting essential enzymes through its ability to create large polyvalent cation through chelation. It exhibits antibacterial, anti-inflammatory and antifungal properties, hence often formulated as cream, lotion, or nail lacquer.
Manufacture
CPO is manufactured by reacting Ciclopirox base with equimolar ethanolamine in a suitable solvent under controlled temperature to form the salt.The product is then crystallized, filtered, washed, and dried to obtain the final active pharmaceutical ingredient.

Applications
CPO is a versatile and effective antifungal agent with a well-established safety profile. Its ability to disrupt fungal cell metabolism and membrane integrity makes it a valuable treatment option for a range of fungal infections.
| It is commonly formulated in creams, lotions, gels, shampoos, and nail lacquers. |
| It is used primarily in treatment of fungal infections of the skin, including tinea corporis (ringworm), tinea cruris(jock itch), tinea pedis (athlete’s foot), and the nails (onychomycosis). |
| Clinically, ciclopirox 1% cream, lotion, and 0.77% topical suspension are indicated for the treatment of cutaneous candidiasis. |
| In dosage of 0.7 %– 1.6% it provides relief of symptoms such as itching, redness. |
| It exerts its anti-inflammatory activity by inhibiting 5-lipoxygenase and cyclooxygenase (COX). |
| Ciclopirox Olamine can be used to study the regulatory mechanisms of metal homeostasis in cells and its effects on cellular processes. |

Nikethamide is a synthetic organic compound derived from nicotinic acid (vitamin B₃). It consists of a pyridine ring linked to a diethyl amide functional group and belongs to the class of pyridine amide derivatives.
(2-Methoxy-1-methyl-2-oxoethyl)triphenylphosphonium bromide is a stabilized phosphonium salt widely used as an intermediate in organic synthesis. Due to presence of an ester group, the compound generates a stabilized ylide that is particularly useful for synthesizing α, β-unsaturated esters, valuable intermediates in pharmaceuticals, agrochemicals, fragrances, and fine chemicals.
p-tert-Butylphenol (PTBP), is an aromatic organic compound consists of a phenol ring substituted with a tert-butyl group at the para (4-) position, giving it improved thermal stability and hydrophobic properties compared to phenol. PTBP features significant hydrogen bonding capabilities, which enhance its solubility in organic solvents. PTBP is used primarily as an intermediate in the manufacturing of polycarbonate plastics, phenolic resins, and epoxy resins.
Yttrium oxide (Y2O3), also known as yttria, is an air-stable, odorless white powder. It is a highly stable, chemically inert ceramic with a very high melting point. It is insoluble in water but readily dissolves in most strong acids. Increasing the specific surface area and porosity of Y2O3 can further improve its relevant physical and chemical properties.
Ethyl 7,7,7-trifluoro-3-hydroxy-3-methylheptanoate is a fluorinated aliphatic hydroxy ester. The presence of the trifluoromethyl group imparts enhanced metabolic stability, lipophilicity, and unique physicochemical properties compared with non-fluorinated analogues. This compound is primarily used as a synthetic intermediate in pharmaceutical and agrochemical research.
2-Chloro-1,1,1-trimethoxyethane is an organochlorine orthoester compound commonly used as a versatile synthetic intermediate in organic and pharmaceutical chemistry. It is a colorless to pale yellow liquid with good reactivity toward nucleophilic substitution and cyclization reactions, making it valuable in the preparation of heterocyclic and bioactive molecules.
