| Baicalin is a flavone glycoside, it is a flavonoid. It is the glucuronide of baicalein.
Baicalin is a flavonoid glycoside derived from plants in the genus Scutellaria. It has anxiolytic, anti-cancer and anti-viral properties, and is used in traditional Chinese medicine. Baicalein and baicalin are chemically related, with baicalin being essentially a conjugated (sugar-attached) form of baicalein. This conjugation can modify their biological functions and impacts, making them distinct in certain aspects even though they share several pharmacological properties. baicalin is often hydrolyzed by gut β-glucuronidase to baicalein (aglycone) and then extensively converted to phase-II conjugates (glucuronides/sulfates), which constrains systemic “free” levels after oral dosing. In cancer models, baicalin/baicalein are reported to modulate NF-κB, PI3K/AKT/mTOR, MAPK, and related programs, with downstream effects on cell-cycle arrest, apoptosis, invasion/EMT, and angiogenesis (model-dependent). Baicalein appears to be antioxidant in normal cells (low Cu). In vitro, baicalein can participate in copper-dependent redox cycling under high Cu conditions, leading to ROS generation. Whether this mechanism contributes meaningfully in vivo remains model-dependent. (higher Cu levels) (May applies to other plant polyphenols as well: Ex apigenin, luteolin, EGCG, and resveratrol). Pathways: Apoptosis Pathways (Intrinsic/Mitochondrial): NF-κB Inhibition : PI3K/Akt/mTOR Signaling Pathway downregulate : MAPK/ERK and JNK Signaling Pathways: STAT3 Signaling: (inhibit) Wnt/β-Catenin Signaling Pathway: (suppress) Other Pathways and Effects: • Cell Cycle Arrests (commonly G0/G1 or G2/M) • Anti-angiogenic Effects: By inhibiting VEGF • Modulation of Oxidative Stress: Balancing reactive oxygen species (ROS) levels in cancer cells can also contribute to its antitumor effects. • In normal cells or under conditions of oxidative stress, baicalin has been shown to act as an antioxidant. • In cancer cells, baicalin may increase ROS levels, triggering apoptosis. Lower doses of baicalin might favor antioxidant responses, whereas higher concentrations could lead to ROS accumulation in cancer cells. Redox effects are concentration- and context-dependent; antioxidant behavior predominates in non-tumor oxidative stress models, whereas ROS increases have been reported in some tumor systems at higher concentrations. • If copper levels are elevated in a cancer cell, the additional ROS generated via copper-mediated reactions may synergize with baicalin’s pro-oxidant effects (if observed at higher doses) to exceed the threshold for cancer cell survival. • Conversely, in normal cells with tightly regulated copper levels, baicalin’s antioxidant properties may help in quenching excess ROS or maintaining redox balance. -IC50 in cancer cell lines: Approximately 50–200 µM (with some variability depending on the cell type). • IC50 in normal cell lines: Generally higher, often exceeding 200 µM, though values will vary with experimental conditions. Many in-vitro IC50 values exceed achievable systemic concentrations after oral dosing without advanced formulation. Low oral bioavailability: classic rat PK reports very low absolute BA bioavailability and evidence of enterohepatic cycling

| Also known as SLC2A1 An important hallmark in cancer cells is the increase in glucose uptake. GLUT1 is an important target in cancer treatment because cancer cells upregulate GLUT1, a membrane protein that facilitates the basal uptake of glucose in most cell types, to ensure the flux of sugar into metabolic pathways. GLUT1 is a member of the facilitated glucose transporter family and is widely expressed in various tissues, including red blood cells, brain, and cancer cells. GLUT1 has been shown to be overexpressed in many types of tumors, including breast, lung, and colon cancer. This overexpression may contribute to the development and progression of cancer by promoting glucose uptake and energy production in cancer cells. GLUT1 is a protein that facilitates the transport of glucose across cell membranes. GLUT1 plays a role in the regulation of glucose metabolism in diabetes. GLUT1 plays a role in the regulation of glucose metabolism in diabetes. GLUT1 is also known to be involved in the Warburg effect. GLUTs are expressed 10–12-fold higher in cancer cells than in healthy tissues, especially in highly proliferative and malignant tumors. Downregulators: -Resveratrol: associated with reduced GLUT1 expression. -Curcumin: downregulate GLUT1 in various cancer cell lines -Quercetin: downregulating the expression and function of GLUT1. -EGCG: suppress GLUT1 expression -Berberine: linked to decreased expression or activity of GLUT1. |
