A similar compound is dexamethasone that also selectively binds to the glucocorticoid receptor with high affinity. This is in contrast to the natural steroid hormones cortisol or corticosterone, which bind to both of the corticosteroid receptors, though they bind to the mineralocorticoid receptor with greater affinity.^[3]
