Nemorosone also inhibits growth of Capan-1, AsPC-1, and MIA-PaCa-2 pancreatic cancer cells (IC50s = 4.5-5.0 μM following a 72-hour treatment) but not human dermal and foreskin fibroblasts (IC50s = >35 μM).1 It induces apoptosis, abolishes the mitochondrial membrane potential, and increases cytosolic calcium concentration in pancreatic cancer cells in a dose-dependent manner. Nemorosone activates the caspase cascade in a dose-dependent manner and inhibits cell cycle progression, increasing the proportion of cells in the G0/G1 phase, in both neuroblastoma and pancreatic cancer cells.1,2 Nemorosone (50 mg/kg, i.p., per day) also reduces tumor growth in an MIA-PaCa-2 mouse xenograft model.3References1.

Ginkgo Biloba Extract is a natural active ingredient extracted from ginkgo leaves. It maintains the structural and functional homeostasis of mitochondria, regulates the expression of Bcl-2 family proteins, blocks caspase cascade activation, and thereby alleviates neuronal apoptosis mediated by oxidative stress. Meanwhile, it upregulates SKP2 expression, inhibits non-Beclin1-dependent autophagy pathways, and ameliorates testicular tissue injury. In animal experimental models, it exerts protective effects on multiple types of neuronal damage and alleviates behavioral sensitization in rats. Against β-amyloid (Aβ)-mediated neurotoxicity, Ginkgo Biloba Extract produces multiple antagonistic effects: inhibiting Aβ-induced abnormal glucose uptake, ROS accumulation, AKT signaling disorder and mitochondrial dysfunction, regulating JNK and ER1/2 signaling pathways, blocking neuronal apoptosis, and suppressing the aggregation and formation of Aβ oligomers. Current research confirms that Ginkgo Biloba Extract has potential research value and application prospects in various neurological and tissue injury diseases including cerebral insufficiency, testicular injury, Alzheimer's disease, Parkinson's disease, multi-infarct dementia, stroke, traumatic brain injury and amyotrophic lateral sclerosis.
