Abstract

Metronidazole is a widely used nitroimidazole-based antimicrobial agent, and structural modification of this scaffold remains an important strategy in drug development. In this study, an in silico absorption, distribution, metabolism, excretion, and toxicity (ADMET) evaluation of metronidazole and its aldehyde derivative, previously synthesized via oxidation, was performed. ADMET predictions were carried out using the ADMETlab 3.0 platform to assess physicochemical properties, drug-likeness, pharmacokinetic behaviour, metabolic stability, and toxicity profiles. The aldehyde derivative exhibited a slight increase in lipophilicity and a corresponding change in predicted membrane permeability compared to metronidazole, although both compounds remained within similar classification ranges. However, the derivative showed reduced metabolic stability, a shorter predicted half-life, and an increased number of toxicity-related alerts, particularly in terms of skin sensitization and medicinal chemistry warnings. Both compounds satisfied major drug-likeness rules and were predicted to be substrates of key cytochrome P450 enzymes, without significant inhibitory effects. The results suggest that aldehyde functionalization may influence the ADMET profile of metronidazole, introducing a balance between minor changes in permeability-related parameters and increased metabolic and safety-related concerns. However, these findings are based solely on in silico predictions and should be interpreted with caution. The present study offers a preliminary comparative assessment of aldehyde modification, which may serve as a basis for further experimental and computational investigations.

Özet

Metronidazol, yaygın olarak kullanılan nitroimidazol türevi bir antimikrobiyal ajandır ve bu yapı iskeletinin kimyasal olarak modifiye edilmesi ilaç geliştirme çalışmalarında önemli bir stratejidir. Bu çalışmada, oksidasyon yoluyla daha önce sentezlenmiş metronidazol aldehit türevi ile metronidazolün absorpsiyon, dağılım, metabolizma, atılım ve toksisite (ADMET) özellikleri in silico yöntemlerle karşılaştırmalı olarak değerlendirilmiştir. ADMET tahminleri, ADMETlab 3.0 platformu kullanılarak gerçekleştirilmiştir. Elde edilen sonuçlar, aldehit türevinin lipofilisitesinde hafif bir artış ve buna bağlı olarak tahmin edilen membran geçirgenliğinde sınırlı bir değişim olabileceğini göstermektedir. Bununla birlikte, her iki bileşik benzer sınıflandırma aralıklarında yer almaktadır. Buna karşılık, aldehit türevinin daha düşük metabolik stabilite, daha kısa tahmini yarı ömür ve özellikle deri duyarlılığı ile ilişkili daha fazla toksisite uyarısı ile ilişkili olabileceği öngörülmüştür. Her iki bileşik de temel ilaç benzerliği kurallarını sağlamış ve başlıca sitokrom P450 enzimleri için substrat olarak tahmin edilmiş olup belirgin inhibitör etkiler göstermemiştir. Sonuçlar, aldehit modifikasyonunun ADMET profili üzerinde etkili olabileceğini ve geçirgenlik ile ilişkili sınırlı değişimlere karşılık metabolik ve güvenlik açısından bazı olumsuzluklar ile ilişkili olabileceğini düşündürmektedir. Bununla birlikte, bu bulgular yalnızca in silico tahminlere dayanmaktadır ve dikkatle yorumlanmalıdır. Bu çalışma, aldehit modifikasyonunun etkilerine ilişkin ön değerlendirme niteliğinde olup, ileri çalışmalar için temel oluşturabilir.
