  摘要：

  CD-45 tyrosine phosphatase [E.C. 3.1.3.48] is an important player in the regulation of cell activation and proliferation in hematopoetic cells. As part of a program in immune response modulation, we prepared the first series of small organic molecule inhibitors of CD-45. The preparation and in vitro screening of these hydroxyphosphonates is described herein. (C) 1997 Elsevier Science Ltd.

  The present paper describes the synthesis and antibacterial activity of novel hydrazone derivatives 4a-s derived from 4-(4-chlorophenyl)-cyclohexane carboxylic acid. All the ninteen newly synthesized novel hydrazone derivatives 4a-s were evaluated for their in vitro antibacterial activity against Staphylococcus aureus and S. pyogenes (Gram-positive bacteria) and Escherichia coli and Pseudomonas aeruginosa (Gram-negative bacteria). Antibacterial activity data revealed that the basic scaffold with R = nitrogen heterocyclic ring such as pyridine, quinoline, imidazole and indole showed significant antibacterial activity (excellent activity), whereas the hetrocyclic ring like benzo[b]furan, furan, thiophene moiety showed good antibacterial activity.
