| ln Vitro |
Through negative regulation of NFκB, alpha-Cyperone's anti-inflammatory effect in LPS-stimulated RAW 264.7 cells is linked to COX-2 and IL-6 arrears [1]. Tubulin is bound by alpha-Cyperone, which also reacts to it and has the ability to severely disrupt microtubule polymerization. This response could have the effect of reducing faults, which is highly advantageous for handling problems that are comparable to AD [2].

| Enzyme Assay |
It was demonstrated that α-Cyperone had a pronounced influence on the tubulin structure, decreased polymerization rate and reduced concentration of polymerized tubulin in vitro. The CD deconvolution analysis concluded that significant conformational changes occurred, demonstrated by a drastic increase in content of β-strands upon binding of α-Cyperone. The fluorescence spectroscopy revealed that a static type of quenching mechanism is responsible for binding of α-Cyperone to tubulin. Upon characterization of various biophysical parameters, it was further deduced that ligand binding was spontaneous and a single site of binding was confirmed. Transmission electron microscopy revealed that upon binding of α-Cyperone to microtubule the number and complexity of fibers were noticeably decreased. The computational analysis of docking suggested that α-Cyperone binds preferably to β-tubulin at a distinct location with close proximity to the GTP binding and hydrolysis site. The ligand interaction with β-tubulin is mostly hydrophobic and occurs at amino acid residues that are exclusively on random coil. The BINANA 1.2.0 algorithm which counts and tallies close molecular interaction by performing defined set of simulations revealed that amino acid residues Arg 48 and Val 62 have registered the highest scores and are possibly crucial in ligand-protein interaction[2].

| Cell Assay |
PGE2 and cytokines released from cells were measured using an EIA assay kit. The expression of iNOS, COX-2, TNF-α, and IL-6 was measured by real-time RT-PCR and/or Western blot analysis. A luciferase assay was performed to measure the effect of α-cyperone on NFκB activity[1].
