PABA (para-Aminobenzoic Acid) is increasingly recognized for its broad spectrum of therapeutic properties, from its role as a building block in pharmaceutical development to its direct medicinal applications. This versatile compound has been explored for its potential in treating various conditions, showcasing its importance in both pharmaceutical research and clinical applications.

Recent studies have highlighted PABA's involvement in innovative treatments and diagnostic procedures. For example, PABA's role in enhancing the noninvasive detection of bacterial pathogens through PET imaging represents a significant advancement in medical diagnostics. This application underscores PABA's potential in aiding the detection and monitoring of infections, including methicillin-resistant Staphylococcus aureus (MRSA), showcasing its relevance in addressing antibiotic resistance challenges (Ordonez et al., 2022).

Furthermore, PABA has been identified as a crucial component in the synthesis of novel molecules with potential anticancer, anti-Alzheimer’s, antibacterial, antiviral, antioxidant, and anti-inflammatory properties. This underscores the compound's versatility and its potential as a therapeutic agent in future clinical trials (Haroon et al., 2023).

The pharmacophore hybridization strategy involving PABA and 1,3,5-triazine to discover new antimalarial agents represents another significant application. This approach led to the identification of compounds exhibiting promising activity against chloroquine-sensitive and resistant strains of Plasmodium falciparum, highlighting PABA’s contribution to combating malaria (Saha et al., 2023).

Moreover, the influence of PABA on root development in Arabidopsis, mediated by its modulation of the root cell cycle, provides insights into its role beyond human health, extending to plant biology and offering potential agricultural applications (Lasok et al., 2023).

These studies collectively underline the multifaceted roles of PABA, from its foundational contributions to pharmaceutical development to its direct applications in therapeutic interventions and diagnostics. As research continues to explore the extensive potentials of PABA, its importance in advancing health sciences and beyond becomes increasingly evident.
