He's played a decisive role in the development and introduction of the natural hormone and related compounds as effective new drugs for the treatment of disease. Six compounds discovered and developed in DeLuca's laboratory are in use worldwide for the treatment of such conditions as vitamin D-resistant rickets, hypoparathyroidism, renal osteodystrophy, psoriasis and osteoporosis. Additional findings from DeLuca's lab are being explored as potential treatments for diabetes, multiple sclerosis and arthritis.
