  Structure−Activity Study of Pentamidine Analogues as Antiprotozoal Agents

  摘要：

  Diamidine 1 (pentamidine) and 65 analogues (2-66) have been tested for in vitro antiprotozoal activities against Trypanosoma brucei rhodesiense, Plasmodium. falciparum, and Leishmania donovani, and for cytotoxicity against mammalian cells. Dications 32, 64, and 66 exhibited antitrypanosomal potencies equal or greater than melarsoprol (IC50 = 4 nM). Nine congeners (2-4, 12, 27, 30, and 64-66) were more active against P. falciparum than artemisinin (IC50 = 6 nM). Eight compounds (12, 32, 33, 44, 59, 62, 64, and 66) exhibited equal or better antileishmanial activities than 1 (IC50 = 1.8 mu M). Several congeners were more active than I in vivo, curing at least 2/4 infected animals in the acute mouse model of trypanosomiasis. The diimidazoline 66 was the most promising compound in the series, showing excellent in vitro activities and high selectivities against T. b. rhodesiense, P. falciparum, and L. donovani combined with high antitrypanosomal efficacy in vivo.

  and orthogonally. As the follow-up studies of the diazo transfer reaction using FSO2N3, we discover that amidines and guanidines are rapidly transformed into tetrazole derivatives when reacting with FSO2N3 under an aqueous environment, which is unprecedented for tetrazole synthesis.

  在此，我们报道了在温和条件下通过 FSO 2 N 3实现四唑的简便合成。FSO 2 N 3已被证明是最强大的重氮化试剂，可将数千种伯胺快速且正交地转化为叠氮化物。作为FSO 2 N 3重氮转移反应的后续研究，我们发现脒和胍在水相环境下与FSO 2 N 3反应时迅速转化为四唑衍生物，这对于四唑合成来说是前所未有的。
