Insights

Onychomycosis, a common fungal nail infection, is difficult to treat due to poor drug penetration. Novel antifungals like AN-2690 show promise for improved nail penetration and durable cure rates.

Area of Science:

  • Dermatology
  • Mycology
  • Medicinal Chemistry

Background:

  • Onychomycosis is a prevalent fungal nail infection causing nail damage.
  • Current treatments (oral and topical) have limited durable cure rates.
  • Treatment challenges stem from the infection's deep location and poor drug penetration.

Purpose of the Study:

  • To address the limitations of existing onychomycosis therapies.
  • To explore novel drug delivery technologies for enhanced antifungal penetration.
  • To evaluate the efficacy of new antifungal agents designed for nail penetration.

Main Methods:

  • Investigated the development of novel antifungal agents.
  • Focused on technologies facilitating drug penetration through the nail plate.
  • Clinical trials were conducted to assess promising candidates like AN-2690.

Main Results:

  • AN-2690, an oxaborole antifungal, demonstrated potential for nail plate penetration.
  • Promising results were observed in ongoing clinical trials for AN-2690.
  • The study highlights progress in developing antifungals with improved pharmacokinetic properties.

Conclusions:

  • Novel antifungal development is crucial for improving onychomycosis treatment outcomes.
  • Targeting nail penetration is a key strategy for effective onychomycosis therapy.
  • AN-2690 represents a promising advancement in treating fungal nail infections.

Antifungal Agents01:15

Antifungal Agents

Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
Hand hygiene01:23

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
Acne Infection01:27

Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Psychosis: Goals of Pharmacotherapy

Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation. For...
