Vincristine sulfate is an alkaloidal natural product that binds to microtubule proteins and inhibits the formation of microtubules, thereby inhibiting mitosis in tumor cells. Vincristine sulfate is used as a microtubule destabilizing agent in research studies for the treatment of hematologic neoplasms such as leukemias and lymphomas, as well as in studies related to sarcomas in children.

Tetrandrine (Sinomenine A) is a naturally occurring biphenylisoquinoline alkaloid, a calcium channel inhibitor. Tetrandrine inhibits voltage-gated calcium channels (ICa) and Ca2+-activated potassium channels.

1. Liensinine, a kind of isoquinoline alkaloid, can antagonize the ventricular arrhythmias.

Vinorelbine ditartrate (KW-2307) is a natural alkaloid and an anti-mitotic agent. Vinorelbine ditartrate has anti-tumor activity, inhibiting cell proliferation and inducing apoptosis.

Cycleanine has potent antibacterial, antifungal, antiplasmodial, and cytotoxic activities.

1. Neferine ((-)-Neferine) has anti-tumor activities , Metabolic activation mediated by CYP3A4 and GSH depletion enhanced Neferine-induced cytotoxicity. 2. Neferine can be helpful to increase the efficacy of DOX and to achieve anticancer synergism by curbing the toxicity. 3. Neferine inhibited high glucose-induced endothelial apoptosis via blocking ROS/Akt/NF-κB pathway, which provides the evidence for using Neferine to treat diabetic vasculopathy. 4. Neferine induced apoptosis in a dose-dependent manner with the hypergeneration of reactive oxygen species, activation of MAPKs, lipid peroxidation, depletion of cellular antioxidant pool, loss of mitochondrial membrane potential, and intracellular calcium accumulation.

3,3'-Diindolylmethane (DIM), a small molecule compound, is a proposed Y preventive agent.

(-)-Chimonanthine (IC50 = 0.93 μM) shows potent inhibitory effects on melanogenesis in theophylline-stimulated murine B16 melanoma 4A5 cells.
