  Synthesis and anti-Pneumocystis carinii activity of conformationally restricted analogues of pentamidine

  摘要：

  A series of conformationally restricted analogues of pentamidine in which the flexible central bridge has been replaced by trans-cyclopropyl, phenyl, pyridinyl, piperazinyl or homopiperazinyl groups as conformationally restricted linkers have been synthesized. The anti-Pneumocystis carinii activity of these compounds was evaluated in a cell culture model and the DNA binding affinity was determined by thermal denaturation measurements. At 1 mu M, compounds 2, 3, 5, 7, 9 and pentamidine were highly effective and caused total inhibition of P. carinii growth in culture. At 0.1 mu M, compounds 2, 5, 7 and 10 were more active than pentamidine with N, N'-bis(4-amidinophenyl)piperazine 7 being approximately 15-fold more effective than pentamidine. The most active compounds, 7 and 10, showed strong binding affinities for calf thymus DNA and poly(dA-dT); however, a clear correlation between DNA binding affinity and the in vitro anti-P. carinii activity of these compounds was not observed. The results suggest that the nature of the central Linker influences the biological actions of these compounds. (C) Elsevier, Paris.

  A series of conformationally restricted congeners of pentamidine in which the flexible pentyl bridge of pentamidine was replaced by trans-1,2-bismethylenecyclopropyl, phenyl, pyridinyl, piperazinyl, homopiperazinyl, and piperidinyl groups were synthesized. The compounds were evaluated for trypanocidal activity in vitro and in vivo against one drug-sensitive and three drug-resistant trypanosome isolates. The DNA binding affinity of the compounds was also studied using calf thymus DNA and poly(dA-dT). The nature of the linker influenced the DNA binding affinity as well as the trypanocidal activity of the compounds. trans-1,2-Bis(4-amidinophenoxymethylene)cyclopropane (1) was over 25-fold more potent than pentamidine against the drug-resistant isolate KETRI 243As-10-3, albeit with comparable DNA binding affinity. NN'-Bis(4-amidinophenyl)homopiperazine (8) was the most potent trypanocide in vitro against all four trypanosome isolates studied, but N,N'-bis(4-amidinophenyl)piperazine (6) was the most effective agent in vivo against both drug-sensitive and drug-resistant trypanosomes.
