The Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathways, especially the JAK2/STAT3 pathway, play vital roles in the development of many malignancies. Overactivation of STAT3 promotes cancer cell survival and proliferation. Therefore, the JAK2/STAT3-signaling pathway

Non-small cell lung cancer (NSCLC) is one of the most common forms and leading causes of cancer-related mortality worldwide, and discovery of new effective drugs still remains imperative to improve the survival rate. Nagilactone E (NLE) is a natural product isolated from Podocarpus nagi seeds, which

Apoptosis is one of the most critical forms of defense against cancer, and the induction of apoptosis by dietary polyphenols represents significant potential for cancer preventive activity. The present study examined polyphenols extracted from selected native Australian fruits--Illawarra plum

Nagilactone E (NLE), a natural product with anticancer activities, is isolated from Podocarpus nagi. In this study, we reported that NLE increased programmed death ligand 1 (PD-L1) expressions at both protein and mRNA levels in human lung cancer cells, and enhanced its localization on the cell

Fruit antioxidants have many health benefits including prevention of cancer development. The native Australian bush fruit Illawarra plum (Podocarpus elatus Endl., Podocarpaceae) has a high content of anthocyanin-rich phenolics, with an antioxidant capacity at levels higher than most fruits. In the

BACKGROUND Different parts of Podocarpus henkelii have been used in many cultures around the world to treat ailments such as cholera, stomach diseases, rheumatism, cancer, canine distemper in dogs and gall sickness in cattle. The aim of this study was to evaluate the biological activity and toxicity

A new abietane mono-norditerpenoid, nagiol A (1), along with three known diterpenoids were isolated from the leaves of Podocarpus nagi. Their structures were elucidated by means of extensive spectroscopic analysis. This is the first report of abietane mono-norditerpenoid separated from plant of the

Phytochemical investigation of the twigs of Podocarpus nagi (Podocarpaceae) led to the isolation of two new abietane-type diterpenoids, named 1β,16-dihydroxylambertic acid (1) and 3β,16-dihydroxylambertic acid (2), along with two new ent-pimarane-type diterpenoids, named

Nine new norditerpenoids and dinorditerpenoids, 2-oxonagilactone A (1), 7β-hydroxynagilactone D (2), nagilactones K and L (3 and 4), 3β-hydroxynagilactone L (5), 2β-hydroxynagilactone L (6), 3-epi-15-hydroxynagilactone D (7), 1α-chloro-2β,3β,15-trihydroxynagilactone L (8), and 15-hydroxynagilactone

Sciadonic acid (SCA; Δ5,11,14-20:3), a non-methylene-interrupted polyunsaturated fatty acid (NMIFA), can substitute for arachidonic acid (AA) and reduce prostaglandin E2 (PGE2) synthesis in macrophages. However, little is known about how SCA exerts its anti-inflammatory effects. The objectives of

MP [4-(3',3'-dimethylallyloxy)-5-methyl-6-methoxyphthalide] was obtained from liquid culture of Pestalotiopsis photiniae isolated from the Chinese Podocarpaceae plant Podocarpus macrophyllus. MP significantly inhibited the proliferation of HeLa tumor cell lines. After treatment with MP,

Aging is characterized by the accumulation of chronic and irreversible oxidative damage, chronic inflammation, and organ dysfunction. To attenuate these aging-related changes, various natural phytochemicals are often applied. Trans-communic acid (TCA), an active component of brown pine leaf extract,

Bioassay-guided fractionation of the EtOH extract of the dried twigs of Podocarpus nakaii Hayata (Podocarpaceae), endemic plant in Taiwan has resulted in isolation of four [3'→8″]-biflavonoid derivatives, amenotoflavone (AF), podocarpusflavone-A (PF), II-4″,I-7-dimethoxyamentoflavone (DAF), and

A new dimeric phenylpropanoid namely podonaka A (1), along with the 13 known compounds including diterpenes (2 and 3), norditerpenes (4 and 5), benzenoids (6-10), steroids (11 and 12), chalcone (13), and megastigmane (14), was isolated from the EtOH extract of Podocarpus nakaii Hayata. The structure
