Various tetrahydrofuran-2-ylmethylamines have been prepared in good yields by an efficient one-step synthesis utilizing the reaction of tetrahydrofurfurylchloride with different secondary cyclic amines without any catalyst. The compounds were tested for their in vitro affinity for the (α4)2(β2)3 and α7* nicotinic acetylcholine receptor (nAChR) subtypes. Pyrrolidine, piperidine and azepane containing analogs (1a, 1b, 1c) showed Ki values in the lower micromolar range for these neuronal nAChR subtypes in rat brain.

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.
