, (2021/04/21)
The present invention features compositions comprising a plurality of therapeutic agents wherein the presence of one therapeutic agent enhances the properties of at least one other therapeutic agent. In one embodiment, the therapeutic agents are cystic fibrosis transmembrane conductance regulators (CFTR) such as a CFTR corrector or CFTR potentiator for the treatment of CFTR mediated diseases such as cystic fibrosis. Methods and kits thereof are also disclosed.

Quinoline-based scaffolds have been the mainstay of antimalarial drugs, including many artemisinin combination therapies (ACTs), over the history ofmoderndrugdevelopment. Althoughmuch progress has beenmade in the search for novel antimalarial scaffolds, itmay be that quinolineswill remain useful, especially if very potent compounds fromthis class are discovered. We report here the results of a structure-activity relationship(SAR) study assessingpotentialunsymmetrical bisquinoline antiplasmodial drug candidates using in vitro activity against intact parasites in cell culture. Many unsymmetrical bisquinolineswere found to be highly potent against both chloroquine-sensitive and chloroquine-resistant Plasmodium falciparum parasites. Further work to develop such compounds could focus on minimizing toxicities in order to find suitable candidates for clinical evaluation.

We present a short and efficient way of synthesizing two synthetically versatile 4-quinolone-3-carboxylate building blocks by cyclopropanation-ring expansion of 3-chloroindoles with α-halodiazoacetates as the key step. This novel transformation was applied towards the synthesis of the antibiotic drug norfloxacin.
