4-Nerolidylcatechol (4NRC), a secondary metabolite described as a potent antioxidant that presents anti-inflammatory, antimalarial, analgesic, and cytotoxic properties, has been receiving prominence in the catechol class. In this work, a theoretical DFT study of the vibrational, structural, and quantum properties of 4-nerolidylcatechol (4NRC) using the B3LYP/6-311G (2d,p) level is presented. e theoretical molecular geometry data were compared with the X-ray data of a similar molecule in the associated literature and a conformational study is presented, with the aim of providing a good comprehension of the 4NRC structural arrangement and stability. Also, HOMO-LUMO energy gap and natural bond orbitals (NBOs) were performed and discussed. e calculated UV spectrum showed similarity to the experimentally obtained data, with transitions assigned. e comparative IR studies revealed that intermolecular hydrogen bonds that stabilize dimeric forms are plausible and also allowed the assignment of several characteristic vibrations. Molecular docking calculations with DNA topoisomerase I-DNA complex (TOPO-I), glyceraldehyde 3-phospate dehydrogenase (GAPDH), and Plasmodium falciparum lactate dehydrogenase (PfLDH) showed binding free energies of −6.3, −6.5, and −7.6 kcal/mol, respectively, which indicates that 4NRC is a good competitive inhibitor for these enzymes.
