Antifungal drugs are crucial in the battle against fungal infections. In our company, we focus on the research and development of innovative antifungal drugs. With advanced technology and a strong research team, we assist you in identifying promising drug candidates targeting specific fungi, accelerating your research to commercialization process.
Overview of Antifungal Drugs
Antifungal drugs are pharmaceuticals employed for the treatment of fungal infections. These infections can manifest in different areas of the body, such as the skin, nails, mucous membranes, and internal organs. Antifungal drugs work by targeting the fungal cells and inhibiting their growth, replication, or by killing the fungi directly.

How Do Antifungal Drugs Work?
There are multiple types of antifungal drugs available, and their mechanisms of action vary.
| Types |
Mechanism |
| Azoles |
Inhibit the synthesis of ergosterol, a vital component of fungal cell membranes |
| Polyenes |
Work by binding to ergosterol in the fungal cell membrane, forming pores that disrupt membrane integrity |
| Echinocandins |
Target the fungal cell wall by inhibiting the synthesis of β-glucan |
| Allylamines |
Inhibit the enzyme squalene epoxidase, which is involved in the synthesis of ergosterol |
| Pyrimidine Analogs |
Interfere with fungal RNA and DNA synthesis by inhibiting the enzyme cytosine deaminase |
Antifungal Drugs for Fungal Infections
Numerous antifungal drugs have obtained regulatory approval for the management of fungal infections, showcasing their effectiveness and safety through clinical trials. Here are several typical antifungal drugs.
Fluconazole
Fluconazole functions by impeding the synthesis of ergosterol, a crucial component of the fungal cell membrane. It is extensively utilized for the treatment of diverse fungal infections, such as candidiasis and cryptococcal meningitis.
Amphotericin B
Amphotericin B, a polyene antifungal drug, is employed for the therapies of severe systemic fungal infections, including invasive aspergillosis and candidiasis. It functions by binding to ergosterol, thereby disrupting the structural integrity of the fungal cell membrane.
Caspofungin
Caspofungin, an echinocandin antifungal agent, exhibits efficacy in treating invasive candidiasis and invasive aspergillosis. Its mechanism of action involves the inhibition of beta-glucan synthesis, a pivotal constituent of the fungal cell wall.

How Do We Develop Antifungal Drugs?
Target Identification and Validation
Our scientists use approaches such as genomics, proteomics and biochemical analysis to identify and verify specific molecular targets in fungal pathogens that are critical for their growth, survival or virulence. Target types include enzymes, proteins or other molecules essential to the fungal life cycle.
Hit Discovery and Lead Optimization
We utilize high-throughput screening (HTS), virtual screening, or natural product screening to identify initial compounds (hits) that exhibit antifungal activity against the target. Next, we optimize these hits through structure-activity relationship (SAR) studies, medicinal chemistry, and lead optimization to enhance their potency, selectivity, and pharmacokinetic properties.
In Vitro Antifungal Activity Evaluation
We perform in vitro assays to evaluate the ability of lead compounds to inhibit fungal growth, replication, or key metabolic processes. Common assays include determining the minimum inhibitory concentration (MIC), time-kill kinetics, or measuring fungal biomass or viability.
Fungal Susceptibility Testing
We use standardized methods to assess the susceptibility of fungal isolates or clinical strains to lead compounds, generating data on the spectrum of activity and susceptibility patterns of compounds against different fungal species.
In Vivo Efficacy and Safety Evaluation
Next, we evaluate the efficacy and toxicity of the lead compound in relevant fungal infection animal models. At the same time, we will conduct toxicology studies to evaluate the safety of the compound.
Formulation Development
We will design and optimize appropriate drug formulations to ensure stability, bioavailability, and effective delivery of antifungal drugs. Common formulations include oral tablets, topical creams, intravenous infusions, or inhalation formulations for specific indications.
