A novel series of gardenamide A derivatives was synthesized as potential anti-Alzheimer's disease agents. The neuroprotective effects of these multifunctional agents against oxygen-glucose deprivation (OGD)-induced neurotoxicity in rat cortical neurons, and hydrogen peroxide (H2O2)- A nd amyloid-β1-42 (Aβ1-42)-induced neurotoxicity in rat hippocampal neurons were evaluated. In vitro studies revealed that these compounds demonstrated moderate to good multifunctional neuroprotective activity. Among the entire series, compounds 10e, 10j, 10n and 10p appeared to be the most active multifunctional neuroprotective agents. Studies indicate that compounds 10e, 10f, 10h, 10i, 10j, 10n and 10p exhibit significant activities against OGD-induced neurotoxicity in rat cortical neurons, and 10e, 10j, 10n and 10p show prominent activities against H2O2- A nd Aβ1-42-induced neurotoxicity in rat hippocampal neurons. Moreover, these derivatives did not exert conspicuous neurotoxicity in rat cortical neurons. Thus, the present study evidently shows that 10e, 10j, 10n and 10p are potent multifunctional neuroprotective agents, which may serve as promising lead candidates for anti-Alzheimer's disease drug development.

In order to discover novel compounds with inhibitory activity against 3-phosphoglycerate dehydrogenase (PHGDH), a series of thiourea derivatives were designed and synthesized based on the structural modification of compound 5d. Compound 5d emerged from the visual database of ChemDiv of 200,000 small molecules by docking score ranking. Inhibition experiments on PHGDH activity of newly synthesized compounds were performed in vitro. Compounds with more than 30percent inhibitory rate at 25?μM on PHGDH were screened for IC50 measurement. Anti-proliferative activity of 4a, 5a, 6e, 6n against A2780, MDA-MB-468, MDA-MB-231 and HEK293T in vitro was evaluated. The results showed that the compound 4a displayed the best inhibitory activity on PHGDH among the newly synthesized compounds, and the compounds 4a, 5a, 6n had a better proliferation inhibition effect on human A2780 cell line than NCT-503 reported previously. In addition, 2D interaction diagrams revealed potential action modes of active compounds with PHGDH.

Poly (ADP-ribose) polymerase-1 (PARP-1) is a potential target for the discovery of chemosensitizers and anticancer drugs. Amentoflavone (AMF) is reported to be a selective PARP-1 inhibitor. Here, structural modifications and trimming of AMF have led to a series of AMF derivatives (9a-h) and apigenin-piperazine/piperidine hybrids (14a-p, 15a-p, 17a-h, and 19a-f), respectively. Among these compounds, 15l exhibited a potent PARP-1 inhibitory effect (IC50 = 14.7 nM) and possessed high selectivity to PARP-1 over PARP-2 (61.2-fold). Molecular dynamics simulation and the cellular thermal shift assay revealed that 15l directly bound to the PARP-1 structure. In in vitro and in vivo studies, 15l showed a potent chemotherapy sensitizing effect against A549 cells and a selective cytotoxic effect toward SK-OV-3 cells through PARP-1 inhibition. 15l·2HCl also displayed good ADME characteristics, pharmacokinetic parameters, and a desirable safety margin. These findings demonstrated that 15l·2HCl may serve as a lead compound for chemosensitizers and the (BRCA-1)-deficient cancer therapy.

Respiratory syncytial virus (RSV) is the main cause of lower respiratory tract diseases in infants and young children, with potentially serious and fatal consequences associated with severe infections. Despite extensive research efforts invested in the identification of therapeutic measures, no vaccine is currently available, while treatment options are limited to ribavirin and palivizumab, which both present significant limitations. While clinical and pre-clinical candidates mainly target the viral fusion protein, the nucleocapsid protein or the viral polymerase, our focus has been the identification of new antiviral compounds targeting the viral M2-1 protein, thanks to the presence of a zinc-ejecting group in their chemical structure. Starting from an anti-RSV hit we had previously identified with an in silico structure-based approach, we have designed, synthesised and evaluated a new series of dithiocarbamate analogues, with which we have explored the antiviral activity of this scaffold. The findings presented in this work may provide the basis for the identification of a new antiviral lead to treat RSV infections.
