Discovery of Novel Apigenin-Piperazine Hybrids as Potent and Selective Poly (ADP-Ribose) Polymerase-1 (PARP-1) Inhibitors for the Treatment of Cancer

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.

Development of 2-amino-4-phenylthiazole analogues to disrupt myeloid differentiation factor 88 and prevent inflammatory responses in acute lung injury

Myeloid differentiation primary response protein 88 (MyD88), an essential adapter protein used by toll-like receptors (TLR), is a promising target molecule for the treatment of respiratory inflammatory diseases. Previous studies explored the activities of novel 2-amino-4-phenylthiazole analogue (6) in inflammation-induced cancer, and identified the analogue as an inhibitor of MyD88 toll/interleukin-1 receptor (TIR) homology domain dimerization. Here, we describe the synthesis of 47 new analogues by modifying different sites on this lead compound and assessed their anti-inflammatory activities in lipopolysaccharide-induced mouse primary peritoneal macrophages (MPMs). The most promising compound, 15d, was found to effectively interact with MyD88 protein and prevented formation of the MyD88 homodimeric complex. Furthermore, 15d showed in vivo anti-inflammatory activity in LPS-caused model of acute lung injury. This work provides new candidates as MyD88 inhibitors to combat inflammation diseases.

Design, synthesis, and evaluation of genipin derivatives for the treatment of Alzheimer's Disease

Twenty-two novel genipin derivatives have been designed, synthesized, and evaluated for their inhibitory activity against acetylcholinesterase (AChE). As a result, compound 13a bearing ligustrazine moiety displayed the most potent AChE inhibitory activity in this series with IC50 value of 218?nm. Besides, MTT assay was performed to investigate the neuroprotection of these compounds against PC12 cells injured by Amyloid β-protein 1–42 (Aβ1–42). Among them, 8a showed higher inhibition rate (%Inhibition?=?22.29) than the positive reference Donepezil (%Inhibition?=?17.65).
