catalposide/catalpa ovata

Catalposide (1) and two related iridoids were isolated from the stem of Catalpa ovata (Bignoniaceae) by bioassay guided fractionation. Catalposide (1) significantly inhibited the production of nitric oxide (NO) in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages in a dose-dependent manner.

Catalposide, the major iridoid glycoside isolated from the stem bark of Catalpa ovata G. Don (Bignoniaceae), was found to inhibit the productions of tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), and interleukin-6 (IL-6), and the activation of nuclear factor kappaB

Certain irinoid-producing plants have been used as herbal anti-inflammatory remedies. Here we evaluated whether catalposide (CATP), a single compound isolated from irinoid-producing plant Catalpa ovata, has a potential for preventing or ameliorating diseases characterized by mucosal inflammation.

Ten new glycosides, 6,10-O-di-trans-feruloyl catalpol (1), 6,6'-O-di-trans-feruloyl catalpol (2), 3,4-dihydro-6-O-di-trans-feruloyl catalpol (10), (8R,7'S,8'R)-lariciresinol 9'-O-β-d-(6-O-trans-feruloyl)glucopyranoside (17), and ovatosides A-F (18-22, 24), were isolated from the stem bark of Catalpa

Catalposide, the major iridoid glycoside isolated from the stem bark of Catalpa ovata G. Don (Bignoniaceae) has been shown to possess anti-microbial, anti-tumoral, and anti-inflammatory properties. Heme oxygenase-1 (HO-1) is a stress response protein and is known to play a protective role against

Catalposide, an active component of Veronica species such as Catalpa ovata and Pseudolysimachion lingifolium, exhibits anti-inflammatory, antinociceptic, anti-oxidant, hepatoprotective, and cytostatic activities. We characterized the in vitro metabolic pathways of catalposide to
