Abstract

Antimicrobial resistance (AMR) continues to threaten the effectiveness of existing therapies, driving the urgent search for novel therapeutic leads from nature. Rubiaceae plant-associated endophytic fungi are increasingly recognized as valuable producers of structurally diverse secondary metabolites with antibacterial, antifungal, and antimycobacterial activities. Unlike previous reviews that primarily focus on bioactive compounds, this narrative-critical review integrates ecological factors influencing endophytic diversity with advanced strategies to awaken cryptic biosynthetic pathways. We systematically evaluate approaches including One Strain-Many Compounds (OSMAC), co-culture, chemical and epigenetic elicitation, genome-guided discovery, and heterologous expression. Furthermore, this review critically analyzes pharmacological metrics, specifically minimum inhibitory concentration (MIC), cytotoxicity, Selectivity Index (SI), mechanisms of action, and the potential of fungal metabolites as antibiotic adjuvants. Current evidence suggests that the clinical development of these natural products is constrained by methodological inconsistencies, a lack of animal model testing, insufficient pharmacokinetic profiling, and large-scale manufacturing hurdles. Future progress in drug discovery will heavily depend on adopting standardized evaluation criteria and comprehensive pharmacological screening to successfully transform these endophytic metabolites into viable clinical candidates.

Keywords: Antimicrobial secondary metabolites; drug discovery; endophytic fungi; OSMAC; Rubiaceae; selectivity index

 

Abstrak

Kerintangan antimikrob (AMR) terus mengancam keberkesanan terapi sedia ada, sekali gus mendorong pencarian segera untuk terapeutik baharu daripada alam semula jadi. Kulat endofit yang berkaitan dengan tumbuhan famili Rubiaceae semakin dikenali sebagai pengeluar pelbagai metabolit sekunder yang memiliki aktiviti antibakteria, antikulat dan antimikobakteria. Tidak seperti ulasan terdahulu yang sebahagian besarnya tertumpu kepada sebatian bioaktif, ulasan ini menggabungkan faktor ekologi yang mempengaruhi kepelbagaian endofit dengan strategi lanjutan untuk meningkatkan laluan biosintetik yang masih samar. Kami menilai pelbagai pendekatan secara sistematik termasuk Satu Strain-Banyak Sebatian (OSMAC), kultur bersama, elisitasi kimia dan epigenetik, penemuan berpandukan genom dan pengekspresan heterolog. Tambahan pula, ulasan ini menganalisis secara kritis metrik farmakologi, khususnya kepekatan perencatan minimum (MIC), kesitotoksikan, Indeks Kepilihan (SI), mekanisme tindakan dan potensi metabolit kulat sebagai adjuvan antibiotik. Bukti semasa mencadangkan bahawa pembangunan klinikal produk semula jadi ini masih dikekang oleh ketidakseragaman metodologi, kekurangan ujian model haiwan, pemprofilan farmakokinetik yang tidak mencukupi dan halangan pembuatan berskala besar. Kemajuan pada masa hadapan dalam penemuan ubat akan sangat bergantung kepada penerapan kriteria penilaian piawai dan penyaringan farmakologi yang komprehensif untuk berjaya mentransformasikan metabolit endofit ini menjadi calon klinikal yang berdaya maju.

Kata kunci: Indeks keselektifan; kulat endofit; metabolit sekunder antimikrob; OSMAC; penemuan ubat; Rubiaceae
