Abstract Glycolysis is drastically increased in tumors and it is the main route to energy production with a minor use of oxidative phosphorylation. Among the key enzymes in the glycolytic process, LDH is emerging as one of the most interesting targets for the development of new inhibitors. In this context, in the present work, we carried out a virtual screening procedure followed by chemical modifications of the identified structures according to a "hit-to-lead" process. The effects of the new molecules were preliminary probed against purified human LDH-A. The compounds active at low micromolar level were additionally characterized for their activity on some cellular metabolic processes by using Raji human cell line. Within the series, 1 was considered the best candidate, and a more detailed characterization of its biological properties was performed. In Raji cells exposed to compound 1 we evidenced the occurrence of effects usually observed in cancer cells after LDH-A inhibition: reduced lactate production and NAD/NADH ratio, apoptosis. The flow cytometry analysis of treated cells also showed cell cycle changes compatible with effects exerted at the glycolytic level. Finally, in agreement with the data obtained with other inhibitors or by silencing LDH-A expression, compound 1 was found to increase Raji cells response to some commonly used chemotherapeutic agents. Taken together, all these finding are in support of the LDH-A inhibiting activity of compound 1.

A series of aminooxadiazoles was optimized for inhibition of Cdc7. Early lead isoquinoline 1 suffered from modest cell potency (cellular IC50 = 0.71 μM measuring pMCM2), low selectivity against structurally related kinases, and high IV clearance in rats (CL = 18 L/h/kg). Extensive optimization resulted in azaindole 26 (Cdc7 IC50 = 1.1 nM, pMCM2 IC50 = 32 nM) that demonstrated robust lowering of pMCM2 in a mouse pharmacodynamic (PD) model when dosed orally. Modifications to improve the pharmacokinetic profile of this series were guided by trapping experiments with glutathione in rat hepatocytes.

Glycogen synthase kinase-3β (GSK-3β) is implicated in abnormal hyperphosphorylation of tau protein and its inhibitors are expected to be a promising therapeutic agents for the treatment of Alzheimer's disease. Here we report design, synthesis and structure-activity relationships of a novel series of oxadiazole derivatives as GSK-3β inhibitors. Among these inhibitors, compound 20x showed highly selective and potent GSK-3β inhibitory activity in vitro and its binding mode was determined by obtaining the X-ray co-crystal structure of 20x and GSK-3β.

Potent small molecule antagonists for the PAC1-R have been discovered. Previously known antagonists for the PAC1-R were slightly truncated peptide ligands. The hydrazides reported here are the first small molecule antagonists ever reported for this class B GPCR.
