  Synthesis of Leukotriene B4 Antagonists Labeled with In-111 or Tc-99m to Image Infectious and Inflammatory Foci

  摘要：

  In previous studies we demonstrated that lipophilic Tc-99m-labeled LTB4 antagonist 1 (RP517) accumulated in infectious foci in rabbits, but hepatobiliary clearance hampered imaging of abdominal lesions. We now report the use of cysteic acid as a pharmacokinetic modifier to improve the water solubility and renal clearance of three hydrophilic analogues of 1. Divalent LTB4 antagonist 17 (DPC11870-11) is a DTPA conjugate for radiolabeling with In-111. Monovalent LTB4 antagonists 15 (BMS57868-88) and divalent LTB4 antagonist 18 (BMS5786881) are conjugated to bifunctional chelator HYNIC for radiolabeling with Tc-99m. The three compounds labeled efficiently with In-111 or Tc-99m with high radiochemical purity and specific activities. Scintigraphic images obtained in New Zealand White rabbits having acute intramuscular E. coli infection demonstrated that all agents were able to clearly visualize the abscess, and clearance was exclusively renal. The biodistribution of the Tc-99m-labeled LTB4 antagonists was affected by the coligands used with the HYNIC chelator and by the monovalent or divalent nature of the receptor binding moiety. The best scintigraphic images were obtained with monovalent HYNIC conjugate 15 using tricine and isonicotinic acid as coligands with HYNIC for coordination with Tc-99m.

  .omega.-[(4,6-Diphenyl-2-pyridyl)oxy]alkanoic acid derivatives: a new family of potent and orally active LTB4 antagonists

  摘要：

  A series of omega-[(4,6-diphenyl-2-pyridyl)oxy]alkanoic acid derivatives was prepared which inhibited the binding of leukotriene B4 to its receptors on guinea pig spleen membranes and on human polymorphonuclear leukocytes (PMNs) and selectively antagonized the LTB4-induced elastase release in human PMNs. On the basis of these three screens, a structure-activity relationship was investigated. Alpha-Substitution on the carboxylic acid side chain led to only small changes in the binding affinities but greatly enhanced the LTB4 antagonist activity. Substitution on the phenyl rings was also evaluated. The terminal carboxylic acid function can be replaced by a tetrazole ring without loss in activity. The beat in vitro LTB4 antagonists of this series were investigated in vivo in the inhibition of LTB4-induced leukopenia in rabbits. Compound 9b (RP69698) displayed potent LTB4 antagonist activity, after oral administration, with an ED50 value of 6.7 mg/kg.
