Synthesis and antimicrobial activity of some netropsin analogues

Nine novel lexitropsins were synthesized by linking two netropsin-like moieties through three different dicarboxylic acids; 9, 10-dihydro-2, 7-phenanthrenedicarboxylic acid; [(3- {[(carboxymethyl)amino]carbonyl}benzoyl) amino]acetic acid and indole-2,5-di

Design, synthesis, and structure-activity relationship studies of novel thienopyrrolidone derivatives with strong antifungal activity against Aspergillus fumigates

In order to further enhance the anti-Aspergillus efficacy of our previously discovered antifungal lead compounds (I), two series of novel azoles featuring thieno[2,3-c]pyrrolidone and thieno[3,2-c]pyrrolidone nuclei were designed and evaluated for their in vitro activity on the basis of the binding mode of albaconazole using molecular docking, along with SARs of antifungal triazoles. Most of target compounds exhibited excellent activity against Candida and Cryptococcus spp., with MIC values in the range of 0.0625 μg/ml to 0.0156 μg/ml. The thieno[3,2-c]pyrrolidone unit was more suited for improving activity against Aspergillus spp. The most potent compound, 18a, was selected for further development due to its significant in vitro activity against Aspergillus spp. (MIC Combining double low line 0.25 μg/ml), as well as its high metabolic stability in human liver microsomes.
