The first non-substrate like inhibitors of human cytosolic phosphoenolpyruvate carboxykinase (PEPCK) competitive with GTP are reported. An effort to discover orally active compounds that improve glucose homeostasis in Type 2 diabetics by reversibly inhibiting PEPCK led to the discovery of 1-allyl-3-butyl-8-methylxanthine (5). We now report modifications at N-1 and C-8 that improved the in vitro activity of the initial xanthine HTS hit by 100-fold and a developing SAR for this class of inhibitor.

Ticks are hematophagous ectoparasites that transmit pathogens and inflict significant economic losses on the cattle industry. Remarkably, they can survive extended periods of starvation in the absence of a host. The primary objective of this study was to investigate the metabolic adaptations that enable the tick to endure starvation using the BME26 cell line as a model system.

Despite the growing interest in Phosphoenolpyruvate carboxykinase 2 (PCK2) as a potential biomarker in cancer research, studies on its clinical relevance and biological processes in glioblastoma are still unexplored. Three main glioma cohorts (TCGA, CGGA, Rembrandt) were extracted to exploit the association between PCK2 expression and clinical relevance through Kaplan-Meier survival analysis, univariate and multivariate cox regression analysis. Immunohistochemistry was used to detect PCK2 expression in glioma samples.

Ectoine is a high-value protective agent with extensive applications in the fields of fine chemicals and biopharmaceuticals, and it is naturally synthesized by Halomonas in extreme environment, however, the current production level cannot meet the growing market demand. In this study, we aimed to develop an efficient and environmentally friendly ectoine production process using Bacillus licheniformis as the host organism. Through introducing ectoine synthetase gene cluster ectABC from Halomonas elongate, as well as optimizing ectABC expression by promoter and 5'-UTR optimization, ectoine titer was increased to 0.
