PTEN Activator

Oroxin B (OB) is a BBB-permeable flavonoid isolated from traditional Chinese herbal medicine Oroxylum indicum (L.) Vent. Oroxin B (OB) possesses obvious inhibitory effect and induces early apoptosis rather than late apoptosis on liver cancer cells through upregulation of PTEN, down regulation of COX-2, VEGF, PI3K, and p-AKT. Oroxin B (OB) selectively induces tumor-suppressive ER stress in malignant lymphoma cells.

Sophocarpine is a PTEN activator and an inhibitor of PI3K/Akt, MEK/ERK, and NF-κB signaling pathways. Sophocarpine upregulates PTEN expression and inhibits PI3K/Akt phosphorylation, arrests tumor cell cycle and induces apoptosis. Sophocarpine inhibits MEK/ERK phosphorylation and VEGF secretion, reducing tumor cell migration. Sophocarpine can also inhibit NF-κB activation and p38 and JNK phosphorylation, reduce the expression of inflammatory factors such as iNOS and COX-2, and activate the Nrf2/HO-1 pathway to reduce oxidative stress. Sophocarpine has anti-tumor, anti-inflammatory, antioxidant and anti-apoptotic effects, and can be used in the research of cancers such as glioblastoma and colorectal cancer, inflammation-related diseases, and Doxorubicin (HY-15142A)-induced cardiac damage.

Tyroserleutide hydrochloride is a tripeptide isolated from the degradation products of porcine spleen with antitumor activity. Tyroserleutide hydrochloride can upregulate the expression of the tumor suppressor gene PTEN and inhibit the activity of AKT and PDK1. Tyroserleutide hydrochloride inhibits tumor cell proliferation and MDM2 phosphorylation by inhibiting the PI3K/AKT pathway, and also upregulates P21, P27, P53, and induces mitochondrial damage and cell apoptosis.

Polyporenic acid C is a lanostane-type triterpenoid. Polyporenic acid C can be isolated from Poria cocos. Polyporenic acid C causes the cleavage of caspase-8 and caspase-3, as well as the cleavage of PARP. Polyporenic acid C reduces the phosphorylation level of Akt (Ser473), increases the phosphorylation of PTEN and p53 (Ser15), and activates JNK. Polyporenic acid C induces Apoptosis. Polyporenic acid C shows anticancer activity against non-small cell lung cancer.

CIB-L43 is an orally active TRBP inhibitor (K_D = 4.78 nM) and enhances disruption of TRBP-Dicer interactions (IC₅₀ = 2.34 μM). CIB-L43 suppresses oncogenic miR-21 biosynthesis, increasing PTEN and Smad7 expression and inhibiting AKT and TGF-β signaling, thereby reducing HCC cell proliferation and migration.

Theasaponin E1 is an orally effective tea saponin. Theasaponin E1 inhibits the proliferation of cancer cells by activating apoptosis. Theasaponin E1 inhibits angiogenesis in ovarian cancer cells and HUVECs by reducing the expression of VEGF. Theasaponin E1 upregulates the phosphorylation level of ATM protein and the expression level of PTEN protein in cancer cells, decreases the phosphorylation levels of Akt, mTOR, p70S6K and 4E-BP1 proteins, downregulates the expression of HIF-1α and NF-κB, and reduces the protein expression of Notch ligands Dll4 and Jagged1. Theasaponin E1 exerts neuroprotective effects by inhibiting the activity of acetylcholinesterase, activating α-secretase and neprilysin, reducing the concentration of Aβ, and inhibiting the activities of β-secretase and γ-secretase. Theasaponin E1 exhibits toxic effects on cancer cells and quinone reductase-inducing activity, and inhibits tumor growth in vivo. Theasaponin E1 induces ferroptosis in Pomacea canaliculata by synergistically disrupting cholesterol homeostasis and sphingolipid metabolism. Theasaponin E1 possesses anti-biofilm activity against Candida albicans. Theasaponin E1 can be used in the research of ovarian cancer, obesity, Alzheimer's disease and fungal infections.

ROCK2-IN-13 is a selective ROCK2 inhibitor. ROCK2-IN-13 reduces nuclear expression by disrupting the interaction of ROCK2 with transcriptional co activators p300> and PGC 1α, repressing oncogenic transcription. ROCK2-IN-13 activates FOXO1 driven PTEN expression, leading to suppression of the PI3K/Akt pathway, induction of G₂/M cell cycle arrest, and promotion of apoptosis. ROCK2-IN-13 ablates the nuclear transcriptional function of ROCK2 that sustains oncogenic signaling and restores the tumor suppressive PTEN/FOXO1 axis. ROCK2-IN-13 can be used for prostate cancer reseach.

Oroxin B (OB) is a flavonoid isolated from traditional Chinese herbal medicine Oroxylum indicum (L.) Vent. Oroxin B (OB) possesses obvious inhibitory effect and induces early apoptosis rather than late apoptosis on liver cancer cells through upregulation of PTEN, down regulation of COX-2, VEGF, PI3K, and p-AKT. Oroxin B (OB) selectively induces tumor-suppressive ER stress in malignant lymphoma cells.
