(+)-Deoxypyridinoline (Dpd, 2) is a cross-link of bone collagen, which is released and excreted in urine during process of bone resorption. It has been shown that this bone collagen degradation product, Dpd (2) is a useful marker for diagnosis of osteoporosis and other metabolic bone diseases. In this paper, the design and synthesis of two immunogens (3, 4) via of conjugation of succinimidyl ester (14) to carrier protein, bovine serum albumin, or keyhole limphet hemocyanin, was presented. Additionally, fluorescent (5) and chemiluminescent (6) tracers were prepared from (-)-acid (13) via in situ activation and subsequent reaction with 6-Fln-CH(2)NH(2) (17) or Acr-NH(2) (18) and hydrolysis. The key hapten (-)-acid (13) was prepared by quaternization of 3-hydroxypyridine derivative (S,S)-(-)-11 with iodide (S)-(-)-10 followed by selective hydrolysis. These immunreagents (immunogens 3 and 4 and tracers 5 and 6) are useful for the development of sensitive and high throughput immunoassays, such as FPIA and CLIA for Dpd (2).
