Naphthalene Derivatives and Quinones from Ventilago denticulata and Their Nitric Oxide Radical Scavenging, Antioxidant, Cytotoxic, Antibacterial, and Phosphodiesterase Inhibitory Activities.

TLDR
New naphthalene derivatives and a new isomer of ventilagolin, together with known anthraquinones, chrysophanol, physcion or emodin 3‐methyl ether, andEmodin, were isolated from vines of Ventilago denticulata and exhibited cytotoxic activity and weak antibacterial activity.
Abstract
New naphthalene derivatives (1 and 2) and a new isomer (3) of ventilagolin, together with known anthraquinones, chrysophanol (4), physcion or emodin 3-methyl ether (5), and emodin (6), were isolated from vines of Ventilago denticulata. The isolated compounds exhibited cytotoxic activity with IC50 values of 1.15 - 40.54 μg/ml. Compounds 1 - 3 selectively exhibited weak antibacterial activity (MIC values of 200.0 - 400.0 μg/ml), while emodin (6) displayed moderate antibacterial activity with MIC value of 25.0 μg/ml. The isolated compounds showed nitric oxide and DPPH radical scavenging activities. Compounds 1 - 3 and 6 exhibited weak xanthine oxidase inhibitory activity, while emodin (6) acted as an aromatase inhibitor with the IC50 value of 10.1 μm. Compounds 1 and 2 exhibited phosphodiesterase 5 inhibitory activity with IC50 values of 8.28 μm and 6.48 μm, respectively.
