  Extended Aromatic Furan Amidino Derivatives as Anti-Pneumocystis carinii Agents

  摘要：

  The. syntheses of nine new derivatives of 2,5-bis[4-(N-alkylamidino)phenyl]furans with extended aromatic systems are reported. The interaction of these dicationic furans with poly(dA)*poly(dT) and with the duplex oligomers d(CGCGAATTCGCG)(2) and d(GCGAATTCGC)(2) was determined by T(m) measurement, and the effectiveness of these compounds against the immunosuppressed rat model of Pneumocystis carinii was evaluated. At a screening dose of 10 mu mol/kg, 4 of the 12 amidino furans described here are more active than the parent compound 1. In general, extension of the aromatic system in the absence of a substitution of the amidino nitrogens resulted in higher affinity for DNA than the parent compound as judged by the larger Delta T(m) values and suggests enhanced van der Waals interactions in the amidino furan-DNA complex. Three of the compounds, 3, 5, and 11, yield cysts counts of less than 0.1% of control when administered at a dosage of 10 mu mol/kg. Compound 3, which does not have an extended aromatic system, is the most active derivative. Although a direct correlation between anti-P. carinii activity and DNA binding affinity was not observed, all compounds which have significant activity have large Delta T(m) values.

  Structure-In Vitro Activity Relationships of Pentamidine Analogues and Dication-Substituted Bis-Benzimidazoles as New Antifungal Agents

  摘要：

  摘要：对于20种戊二胺类似物、7种戊二胺的主要代谢产物以及30种二阳离子取代的双苯并咪唑类化合物进行了筛选，评估它们对念珠菌和隐球菌的抑制和杀真菌活性。大多数化合物的MIC（80%菌株被抑制的最小抑菌浓度）与两性霉素B和氟康唑相当。与氟康唑不同，许多这些化合物表现出强效的杀真菌活性。对于念珠菌而言，最有效的化合物的MIC80为≤0.09μg/ml，对于隐球菌而言，最有效的化合物的MIC80为0.19μg/ml。选择的化合物也对曲霉、索兰镰孢霉、除念珠菌外的其他种类的念珠菌，以及氟康唑耐药菌株的活性。从这里呈现的数据清楚地表明，有必要进行进一步的研究，以确定这些化合物的结构活性关系、作用机制和毒性，以及它们在体内的疗效，以确定它们的临床潜力。
