Protein-protein interactions (PPIs) constitute many potential therapeutic targets for the discovery of new drugs. Given their specificity, PPIs are more challenging to target than other ligands. Thus, finding the best screening process can be difficult. Moreover, PPIs often have no direct accessible activity readout. Therefore, it can be unclear which test to choose for the screening of small molecules targeting PPIs. Given that noncellular assays are the most suitable both as first screening assays and for high-throughput screening (HTS), here we focus on noncellular screening assays. For each assay, we discuss the principles and advantages/drawbacks and provide a recent example. We also highlight the crucial parameters to take into account to select the most suitable assays to screen PPI modulators.

In patients with type 2 diabetes mellitus (DM), excessive gluconeogenesis is considered a major contributor to hyperglycemia. Therefore, targeting fructose 1,6-bisphosphatase (FBPase), a key regulatory enzyme involved in gluconeogenesis, has gained interest as a potential therapeutic target for managing DM. In this study, a library of 42 structurally-related chromone derivatives (including flavonoids, 2-styrylchromones, and 2-(4-arylbuta-1,3-dien-1-yl)chromones, named as 2-styrylchromone-related derivatives), as well as 4- and 5-styrylpyrazoles, were tested against human FBPase using a noncellular microanalysis screening system.

Pancreatic cancer comprises different subtypes, where most cases include ductal adenocarcinoma (PDAC). It is one of the deadliest tumor types, with a poor prognosis. In the majority of patients, the disease has already spread by the time of diagnosis, making full recovery unlikely and increasing mortality risk.

Microvascular destabilization is the primary cause of the inner blood-retinal barrier (iBRB) breakdown and increased vascular leakage in diabetic retinopathy (DR). Microvascular destabilization results from the combinational effects of increased levels of growth factors and cytokines, involvement of inflammation, and the changed cell-to-cell interactions, especially the loss of endothelial cells and pericytes, due to hyperglycemia and hypoxia. As the manifestation of microvascular destabilization, the fluid transports via paracellular and transcellular routes increase due to the disruption of endothelial intercellular junctional complexes and/or the altered caveolar transcellular transport across the retinal vascular endothelium.

The hepatocellular carcinoma (HCC) features a remarkable epidemiological burden, ranking as the third most lethal cancer worldwide. As the HCC-related molecular and cellular complexity unfolds as the disease progresses, the use of a myriad of in vitro models available is mandatory in translational preclinical research setups. In this review paper, we will compile cutting-edge information on the in vitro bioassays for HCC research, (A) emphasizing their morphological and molecular parallels with human HCC; (B) delineating the advantages and limitations of their application; and (C) offering perspectives on their prospective applications.

Subretinal fibrosis is the end-stage sequelae of neovascular age-related macular degeneration. It causes local damage to photoreceptors, retinal pigment epithelium, and choroidal vessels, which leads to permanent central vision loss of patients with neovascular age-related macular degeneration. The pathogenesis of subretinal fibrosis is complex, and the underlying mechanisms are largely unknown.
