Steroids upregulate beta receptors

Due to membrane-bound CYP3A4's natural propensity to conglomerate, it has historically been difficult to study drug binding in both solution and on surfaces. Co-crystallization is difficult since the substrates tend to have a low Kd (between 5-150 μM) and low solubility in aqueous solutions. [33] A successful strategy in isolating the bound enzyme is the functional stabilization of monomeric CYP3A4 on Ag nanoparticles produced from nanosphere lithography and analyzed via localized surface plasmon resonance spectroscopy ( LSPR ). [34] These analyses can be used as a high-sensitivity assay of drug binding, and may become integral in further high-throughput assays utilized in initial drug discovery testing. In addition to LSPR, CYP3A4-Nanodisc complexes have been found helpful in other applications including solid-state NMR , redox potentiometry, and steady-state enzyme kinetics . [34]
