Sortin1 is an inhibitor of vesicular biogenesis and transport, which is shared among eukaryotes and plants with an unknown mode of action. Toward exploration of its target proteins, we developed alkyne as well as biotin conjugated photoaffinity probes derived from Sortin1. Due to the presence of phenylketone moiety, Sortin1 was anticipated to serve as a photoreactive group in a similar manner to a commonly used photoreactive group, benzophenone. The core structure based on 5-oxo-1,4-dihydroindenopyridine was constructed in one step using three-component Hantzsch dihydropyridine synthesis. We demonstrated that Sortin1 displayed photocrosslinking reactivity against a model binding protein, which would be useful for capturing and detecting binding proteins.

A simple, mild and green approach has been developed for the synthesis of asymmetrical heterobiaryls under the irradiation of visible light without any oxidants and promoting reagents through using Pd/CeO2 nanocomposite photocatalyst. This method can tolerate considerable functional groups such as electron-donating groups and electron-withdrawing groups through C–C cross-coupling. Moreover, we obtain the products with moderate yields in an efficient way. Finally, a plausible mechanism is proposed.

Human sirtuin 5 (SIRT5) is a protein deacylase regulating metabolic pathways and stress responses and is implicated in metabolism-related diseases. Small-molecule inhibitors for SIRT5 are sought as chemical tools and potential therapeutics. Herein, we proposed a customized virtual screening approach targeting catalytically important and unique residues Tyr102 and Arg105 of SIRT5. Of the 20 tested virtual screening hits, six compounds displayed marked inhibitory activities against SIRT5. For the hit compound 19, a series of newly synthesized (E)-2-cyano-N-phenyl-3-(5-phenylfuran-2-yl)acrylamide derivatives/analogues were carried out structure–activity relationship analyses, resulting in new more potent inhibitors, among which 37 displayed the most potent inhibition to SIRT5 with an IC50 value of 5.59?±?0.75?μM. The biochemical studies revealed that 37 likely acts via competitive inhibition with the succinyl-lysine substrate, rather than the NAD+ cofactor, and it manifested substantial selectivity for SIRT5 over SIRT2 and SIRT6. This study will aid further efforts to develop new selective SIRT5 inhibitors as tools and therapeutics.

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.
