[Display omitted] • A DFT study of CUR interacting with B 40 and SiB 39 based carriers. • Interaction energy between CUR and B 40 is chemisorption. • B 40 and SiB 39 are electronically sensitive to CUR drug. • Molecular docking results illustrated that CUR/B 40 complexes have a good docking score with COX1, and TNF-alpha receptors. In this paper, density functional theory calculations have been employed to study the interaction of curcumin through β-diketone- and enol- forms with the borospherene molecule (B 40) and its silicon-doped variant (SiB 39) for application as a nanocarrier for designing a drug delivery system. The obtained results from binding energies analysis indicated that the enol form (state II: −1.32 eV) and β-diketone form (state III: −2.51 eV) of curcumin prefers a strong polar covalent B-O and Si-O bonds through carbonyl groups after the interaction with B 40 and SiB 39 fullerenes. The boron fullerene doped with silicon atom improves the adsorption of β-diketone form and has higher binding energy values and increased dipole moment. So, SiB 39 fullerene is more sensitive to the presence of β-diketone (state III: 76.84 %) and enol form is (state IV: 93.68 %) compared to the B 40 fullerene due to the alteration in energy gap. According to molecular docking analysis the β-diketone curcumin conjugated with SiB 39 (state III) and B 40 fullerenes (state I) revealed the best binding affinity with the tumor necrosis factor alpha (TNF-α) receptor (-8.9 kcal/mol) and the cyclooxygenase-1 (COX-1) receptor (-8.8 kcal/mol). The anticancer activities of β-diketone curcumin conjugated B 40 and SiB 39 fullerenes improved in comparison with curumin towards Epidermal growth factor and Human Epidermal Growth Factor Receptor 2 receptors. Molecular docking simulation analysis illustrated that the interaction of curcumin conjugated B 40 and SiB 39 fullerenes have great potential for the anticancer and anti-inflammatory activities in contrast to Curcumin. Thus, the molecular docking and density functional theory analysis confirm that curcumin decorated B 40 and SiB 39 fullerenes have significant potential to be explored further in cancer and inflammation treatments.
