There is currently a public health crisis due to the rise of multidrug-resistant tuberculosis cases, as well as the rise in the number of deaths from tuberculosis. To achieve the United Nations Sustainable Development Goal of ending the tuberculosis epidemic by 2030, new treatments are urgently required. We previously reported the discovery of , a preclinical candidate that acted through inhibition of the lysyl tRNA synthetase (LysRS). In this report, the full medicinal chemistry program is reviewed from the original hit through to the optimized lead. The work was guided by the first crystal structures of LysRS. The physicochemical and pharmacokinetic properties were optimized to afford compounds suitable for evaluation in mouse efficacy models of tuberculosis and with the potential for clinical development.

Word count of the full article: 4834Diabetic cardiomyopathy (DCM) is defined as myocardial dysfunction in diabetes mellitus (DM) patients independent of coronary artery disease (CAD) or hypertension (HTN). With high morbidity and mortality, DCM poses a significant threat to patient health. Its underlying pathogenesis remains incompletely elucidated, and the prolonged subclinical phase renders early diagnosis and precise treatment clinically challenging.

Cryptosporidiosis causes severe diarrhea in children and livestock. However, the absence of suitable rodent models has led to a lack of effective drugs and vaccines. In this study, genetically tractable rat and mouse models were developed for the two main causes of human cryptosporidiosis: Cryptosporidium hominis and C.

Endothelial cells regulate diverse vascular functions by perceiving and reacting to laminar shear stress. In this study, a novel shear-sensing receptor was identified through the use of a pro-inflammatory protein, lysyl-tRNA synthetase (KARS), which is known to be secreted from endothelial cells via autophagy. Binding assays demonstrated that cytokeratin-1 (CK1) interacts with KARS at the endothelial cell surface.

The protozoan parasite causes Chagas disease, which is among the deadliest parasitic infections in Latin America. Current therapies are toxic and lack efficacy against the chronic stage of infection; thus, new drugs are urgently needed. Here, we describe a previously unidentified series of quinazoline compounds with potential against and the related trypanosomatid parasites and .
