-resistant strains, in the range of 0.1-5 microg mL-1, which is comparable to many established antibacterial agents. Antifungal activity was also found in the range of 20-50 microg mL-1 MIC against Aspergillus niger and Candida albicans, again comparable with established antifungal drugs. A quinoline derivative was found to protect mice against S. aureus infection for a period of up to six days after a single
描述了80种与二霉素和噻唑类相关的短小沟结合剂的合成和性能。化合物的设计主要基于小沟结合剂和DNA之间的疏水相互作用而增加的亲和力。疏水性芳族头基(包括喹啉基和苯甲酰基衍生物)的引入以及烯烃作为连接剂的引入,导致几种具有MIC的金黄色葡萄球菌的强活性抗菌化合物(对甲氧西林敏感和耐药的菌株)范围为0.1-5 microg mL -1,与许多已建立的抗菌剂相当。还发现针对黑曲霉和白色念珠菌的抗真菌活性为20-50微克mL-1 MIC,再次与已确立的抗真菌药物相当。

A new synthesis of polyamide minor groove binders in which diversity is introduced by the nucleophilic substitution of a 2-sulfido-1,3,2-diazaphospholidinyloxy substituent by volatile secondary amine nucleophiles is described. Such a method has potential value for economically investigating structure–activity relationships in this important class of compounds through library synthesis. As an example using this method are prepared two new minor groove binders with pyrrolidinyl or piperidinyl tail groups that are close relatives of highly active antibacterial minor groove binders with morpholinyl tail groups. The antibacterial activity found against Staphylococcus aureus and Mycobacterium spp. indicates that the pKa of this set of compounds is not the dominant factor in determining the antibacterial activity.

AnimalAfricantrypanosomiasis (AAT) is a significant socioeconomic burden for sub-Saharan Africa because of its huge impact on livestock health. Existing therapies including those based on minorgroovebinders (MGBs), such as the diamidines, which have been used for decades, have now lost efficacy in some places because of the emergence of resistant parasites. Consequently, the need for new chemotherapies

This paper describes the design and synthesis of Strathclyde minor groove binders (S-MGBs) that have been truncated by the removal of a pyrrole ring in order to mimic the structure of the natural product, disgocidine.
