The control and treatment of rheumatoid arthritis is a challenge in today's
world. Therefore, the pursuit of natural disease-modifying antirheumatic drugs
(DMRDs) remains a top priority in rheumatology. The present study focused on
curcumin and its derivatives in the search for new DMRDs. We focused on prominent
p38 mitogen-activated protein (MAP) kinase p38? which is a prime regulator of
tumor necrosis factor-? (TNF-?), a key mediator of rheumatoid arthritis. In the
present study, we used the X-ray crystallographic structure of p38? for molecular
docking simulations and molecular dynamic simulations to study the binding modes
of curcumin and its derivatives with the active site of p38?. The ATP-binding
domain was used for evaluating curcumin and its derivatives. Molecular docking
simulation results were used to select 4 out of 8 compounds. These 4 compounds
were simulated using GROMACS molecular simulation platform; the results generated
were subjected to molecular mechanics-Poisson Boltzmann surface area (MM-PBSA)
calculations. The results showed cyclocurcumin as a potential natural compound
for development of a potent DMRD. These data were further supported by inhibition
of TNF-? release from lipopolysaccharide (LPS)-stimulated human macrophages
following cyclocurcumin treatment.
