| Targets |
- 14-Deoxyandrographolide targets calcium-mediated signaling pathways in rat uterine smooth muscle.[1]
- 14-Deoxyandrographolide targets tumor necrosis factor receptor superfamily member 1A (TNFR1A) in hepatocytes, acting via the NO/cGMP pathway [2] |
|---|---|
| ln Vitro |
- Inhibition of rat uterine smooth muscle contractility: Isolated rat uterine smooth muscle strips were treated with 14-Deoxyandrographolide at 10, 30, and 100 μM. At 100 μM, it inhibited KCl (60 mM)-induced contractions by 62% and oxytocin (10 nM)-induced contractions by 58%, compared to the control group. The inhibition was concentration-dependent, with no significant effect at 10 μM. Mechanistically, it reduced calcium influx into smooth muscle cells, as evidenced by decreased intracellular calcium levels (measured via fluorescent calcium indicator)[1]
- Desensitization of hepatocytes to TNF-α-induced apoptosis: Primary rat hepatocytes were pretreated with 14-Deoxyandrographolide (10, 30 μM) for 1 hour, then exposed to TNF-α (10 ng/mL) for 24 hours. The 30 μM dose reduced apoptosis rate by 45% (assessed via Hoechst 33258 staining) compared to the TNF-α-only group. It also increased the release of TNFR1A into the culture supernatant by 35% (30 μM) and elevated intracellular NO levels by 40% (30 μM) and cGMP levels by 38% (30 μM). The effect was reversed by a NO synthase inhibitor (L-NAME), confirming dependence on the NO/cGMP pathway[2] |
| Enzyme Assay |
- NO concentration assay in hepatocytes: Primary rat hepatocytes were incubated with 14-Deoxyandrographolide (10, 30 μM) for 1 hour. The culture supernatant was collected, and NO concentration was measured using the nitrate reductase method: supernatant was mixed with nitrate reductase and cofactors, incubated at 37°C for 30 minutes, then reacted with Griess reagent. Absorbance was read at 540 nm, and NO concentration was calculated from a standard curve[2]
|
| Cell Assay |
- Hepatocyte apoptosis assay: Primary rat hepatocytes were seeded in 6-well plates at 5×10⁵ cells/well and cultured for 24 hours. Cells were pretreated with 14-Deoxyandrographolide (10, 30 μM) for 1 hour, then treated with TNF-α (10 ng/mL) for 24 hours. Apoptosis was detected by two methods: 1) Hoechst 33258 staining (counting apoptotic nuclei under fluorescence microscope, apoptosis rate = apoptotic nuclei/total nuclei × 100%); 2) caspase-3 activity assay (lysing cells, incubating with caspase-3 substrate, measuring fluorescence at 460 nm after excitation at 380 nm). The 30 μM dose reduced caspase-3 activity by 42% compared to the TNF-α-only group[2]

| Animal Protocol |
- Rat uterine smooth muscle preparation: Female Sprague-Dawley rats (200–220 g) in estrus were sacrificed by cervical dislocation. The uterus was excised, cleaned of connective tissue, and cut into 2–3 mm longitudinal strips. Each strip was mounted in a 5 mL organ bath containing Krebs-Ringer bicarbonate solution (maintained at 37°C, gassed with 95% O₂ and 5% CO₂) and connected to a force transducer to record contractile tension. After a 30-minute equilibration period, KCl (60 mM) or oxytocin (10 nM) was added to induce contractions. Once contractions stabilized, 14-Deoxyandrographolide (dissolved in DMSO, diluted in Krebs solution to final concentrations of 10, 30, 100 μM) was added sequentially, and contractile changes were recorded for 20 minutes per concentration[1]

| Additional Infomation |
14-Deoxyandrographolide is a diterpenoid lactone.
It has been reported that 14-deoxyandrographolide exists in Andrographis paniculata and Antrodia camphoratus, and there are related data reports. - The inhibitory effect of 14-deoxyandrographolide on uterine smooth muscle contraction is mediated by reducing the influx of extracellular calcium ions, rather than blocking the release of intracellular calcium ions[1]. - 14-deoxyandrographolide desensitizes hepatocytes to TNF-α-induced apoptosis by promoting the release of TNFR1A (reducing the amount of TNFR1A that can bind to TNF-α on the cell surface), and this process requires activation of the NO/cGMP pathway[2]. |
