Avis client

Based on 1 Customer Validation

Methyl protodioscin (NSC-698790; Smilax saponin B) is a multi-target, selective, steroidal diglycoside inhibitor with antitumor activity that induces cell cycle arrest. The mechanism of action of Methyl protodioscin is complex, involving the induction of G2/M cell cycle arrest, regulation of the Bcl-2/Bax apoptotic pathway, inhibition of the Akt1/c-Myc axis and MAPK/ERK signaling, while simultaneously downregulating ADAM15 and inducing FOXO1 to reduce cholesterol synthesis. It also inhibits the JNK/c-Jun pathway, reducing the production of inflammatory factors (IL-6, TNF-α). Methyl protodioscin exhibits significant antitumor (inhibiting proliferation, migration, invasion, and inducing apoptosis), anti-inflammatory, and anti-restenosis activities. Methyl protodioscin can be used in research on lung cancer, prostate cancer, pancreatic cancer, and other tumors, as well as inflammatory diseases such as airway inflammation and enteritis.

In Vitro

Methyl protodioscin (10 nM-0.1 μM; 48 h) was screened in vitro against 60 human cancer cell lines, showing strong cytotoxicity against most solid tumor cells (GI₅₀ ≤ 10.0 μM), with the strongest selectivity against colon cancer cells HCT-15 (GI₅₀ = 1.93 μM) and breast cancer cells MDA-MB-435 (GI₅₀ = 1.69 μM), and moderate toxicity against leukemia cells (GI₅₀ 10-30 μM); the GI₅₀ values ??of methyl protodioscin against various tumor cells ranged from 1.69 to 50 μM (e.g., MDA-MB-435: 1.69 μM, DU145: approximately 4 μM), and the IC₅₀ against vascular smooth muscle cells A7r5 was approximately 9 μM^[1].
Methyl protodioscin (5-20 μM; 48 h) dose-dependently inhibited proliferation in A549 lung cancer cells, inducing G2/M phase cell cycle arrest and apoptosis, downregulating Bcl-2 expression, upregulating Bax expression, activating caspase-3, reducing mitochondrial membrane potential, and promoting cytochrome c release^[2].
Methyl protodioscin (1-10 μM; 24-48 h) inhibited proliferation (48-hour IC₅₀ approximately 4 μM), migration, and invasion in DU145 prostate cancer cells, inducing G2/M phase arrest and apoptosis, downregulating SREBP1, SREBP2, and HMGCR mRNA expression, upregulating ABCA1 and FOXO1 protein expression, and inhibiting P-ERK activity^[3].
Methyl protodioscin (15-50 μM; 24-48 h) in PANC-1 (IC₅₀ = 34.4 μM) and MIA PaCa-2 (IC₅₀ = 50 μM) In pancreatic cancer cells, methyl protodioscin inhibits proliferation, induces G2/M phase arrest and apoptosis, downregulates the expression of glycolysis-related genes Glut1, HK2, LDHA, and PDK1, and inhibits the Akt1/c-Myc signaling pathway^[4].
Methyl protodioscin (1-100 ng/mL; 12-48 h) repairs inflammation-induced barrier function damage in Caco-2 intestinal epithelial cells, promotes crypt formation in mouse intestinal crypt cultures (10 ng/mL being optimal), and upregulates RegIIIc mRNA expression^[5].
Methyl protodioscin (3-9 μM; 16-24 h) inhibits proliferation (IC₅₀ approximately 9 μM) and migration in A7r5 vascular smooth muscle cells, induces G0/G1 phase arrest, and downregulates the protein expression and activity of ADAM15, P-FAK, P-ERK, and MMP-2/9^[6].
Methyl protodioscin (10-100 μM; 4 h) inhibits IL-1β-induced IL-6, IL-8, and TNF-α production in A549 cells and inhibits JNK/c-Jun activation; 100 μM treatment of MH-S macrophages for 24 hours slightly inhibits NO production, but this is accompanied by slight cytotoxicity^[6].

Protein expression^[6].
Methyl protodioscin (30 mg/kg, 60 mg/kg; oral administration; single dose; 16 h) reduced total cell and neutrophil/macrophage infiltration in bronchoalveolar lavage fluid, decreased mRNA expression of IL-6, IL-1β, and TNF-α in lung tissue, and improved pathological changes such as alveolar wall thickening and alveolar lumen narrowing in a LPS-induced acute lung injury model in male ICR mice^[7].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
