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.

A series of novel 1,4-disubstituted piperidine/piperazine derivatives were designed, synthesized and evaluated for their in vitro activities against HIV-1 Bal (R5) infection in CEMX174 5.25M7 cells. A majority of these compounds showed potent anti-HIV-1 activities with IC50 at nanomolar levels. N-(4-Fluoro-benzyl)piperazine analog B07 hydrochloride exhibited potency against HIV-1 activity similar to that of TAK-220 hydrochloride, but it had much better water solubility (25 mg/ml in phosphate sodium buffer at 25 °C) and oral bioavailability (56%) than TAK-220 hydrochloride (a solubility of 2 mg/ml and oral bioavailability of 1.4%). These results suggest that B07 hydrochloride may serve as a better lead for the development of new anti-HIV-1 therapies or microbicides for treatment and prevent of HIV-1 infection.

A triazole derivative of formula 1 or a pharmaceutically acceptable salt, hydrate, solvate or isomer thereof is superior to the conventional antifungal drugs in antifungal activity against a wide spectrum of pathogenic fungi, and has advantageously low toxicity.
