9-methoxyellipticine is an indole alkaloid from the roots of Ochrosia acuminata. Antitumor properties of 9-methoxyellipticine were demonstrated. 9-Methoxyellipticine possesses a relatively broad spectrum of antitumor activity, 10 of 17 mouse neoplasms tested having responded. Both intraperitoneal and oral activity have been noted. Significant activity was seen against both the ascites and solid forms of the Walker rat carcinosarcoma 256. 9-methoxyellipticine binds DNA through a single step mechanism, can be considered as a pure intercalator.

BMY-7378 is a multi-targeted inhibitor of α2C-adrenoceptor and α1D-adrenoceptor with pKi of 6.54 and 8.2, respectively, and acts as a mixed agonist and antagonist for 5-HT1A receptor with pKi of 8.3. BMY-7378 was at the preclinical stage of development for the treatment of anxiety disorders, but later was discontinued.

Morphinone is an oxidation product of morphine with weak agonistic activity toward mu opioid receptor. Morphinone is the intermediate when morphine is being converted to hydromorphone. Morphinone is toxic compound, subcutaneous administration of morphinone produced a reduction of hepatic non-protein sulfhydryl concentration. Glutathione or cysteine significantly decrease Morphinone toxicity.

Methyl jasmonate (MJ) is a natural cyclopentanone lipid belonging to the jasmonates (JAs) family of plant oxylipin stress hormones (oxygenated fatty acids). Methyl jasmonate is found universally in the plant kingdom and functions to regulate plant growth and development, as well as in stress responses through signal transduction pathways. Methyl jasmonate has recently been found to have anti-cancer activity. MJ (1) arrests cell cycle, inhibiting cell growth and proliferation, (2) causes cell death through the intrinsic/extrinsic proapoptotic, p53-independent apoptotic, and nonapoptotic (necrosis) pathways, (3) detaches hexokinase from the voltage-dependent anion channel, dissociating glycolytic and mitochondrial functions, decreasing the mitochondrial membrane potential, favoring cytochrome c release and ATP depletion, activating pro-apoptotic, and inactivating antiapoptotic proteins, (4) induces reactive oxygen species mediated responses, (5) stimulates MAPK-stress signaling and redifferentiation in leukemia cells, (6) inhibits overexpressed proinflammatory enzymes in cancer cells such as aldo-keto reductase 1 and 5-lipoxygenase, and (7) inhibits cell migration and shows antiangiogenic and antimetastatic activities. Finally, MJ may act as a chemosensitizer to some chemotherapics helping to overcome drug resistant. The complete lack of toxicity to normal cells and the rapidity by which MJ causes damage to cancer cells turn MJ into a promising anticancer agent that can be used alone or in combination with other agents. Methyl jasmonate detached hexokinase 2 from a voltage-dependent anion channel causing a reduction in mitochondrial transmembrane potential that led to the release of cytochrome C and apoptosis inducing factor resulting in intrinsic apoptosis. Blocked adenosine triphosphate synthesis caused by mitochondrial injury hampered oxidative phosphorylation and led to cell necrosis. Methyl jasmonate may be an adjuvant therapy for liver tumors due to its mechanism in cancer cells compared to that in normal cells: The major function is to inhibit glycolysis instead of changing aerobic metabolism.

Auraptene (7-Geranyloxycoumarin) is the best known and most abundant prenyloxycoumarin present in nature. It is synthesized by various plant species, mainly those of the Rutaceae and Umbelliferae (Apiaceae) families, comprising many edible fruits and vegetables such as lemons, grapefruit, and orange. Auraptene has shown a remarkable effect in the prevention of degenerative diseases, in particular, it has been reported to be one the most promising known natural chemopreventive agents against several types of cancer. The effect in humans is not yet known.

AMPHETAMINE TARTRATE at doses of less than 5 mg/kg tartrate cause hyperphagia and weight gain of castrated rats. It was available in France until 1971 as restricted prescription drug Corydrane.

Isosafrole, a stiripentol analog, is a potent LDH inhibitor. Stiripentol is a new-generation antiepileptic drug, and its chemical structure is unrelated to other antiepileptic drugs. Seizures and epileptiform activity are reduced by inhibition of the metabolic pathway via lactate dehydrogenase (LDH), which is a component of the astrocyte-neuron lactate shuttle. Isosafrole is a substructure of stiripentol that lacks the hydroxyl group and tertiary-butyl group of stiripentol. Isosafrole strongly inhibited the pyruvate-to-lactate conversion by both LDH1 and LDH5, suggesting that it inhibits lactate production itself. Isosafrole suppresses seizures in vivo. Going by the lactate reduction by ketogenic diets, LDH inhibitors for the pyruvate-to-lactate conversion, such as isosafrole, would be more effective for antiepileptic actions. Isosafrole is a known inducer of some of the liver enzymes of the cytochrome P-450 group in rodents, especially CYP1A2.

Imetit (S-[2-(4-(imidazolyl)ethyl]isothiourea) is a highly specific and potent histamine H3 receptor agonist. It is widely used to study H3-mediated signaling.

4-Piperidinol, 1-phenethyl-4-phenyl acetate (PEPAP) is a synthetic opioid discovered by Janssen in 1960. PEPAP is an analog of meperidine, it is abused and illegally sold on streets as a "synthetic heroin".

Zolantidine is the novel benzthiazole derivative. It is a centrally acting potent antagonist of histamine at H2-receptors. It was found to be a competitive inhibitor of the histamine catabolising enzyme in brain, histamine N-methyltransferase. High aggression in histamine N-methyltransferase knockout mice was suppressed by treatment with zolantidine, indicating that abnormal histamine H2 receptor activation promoted aggression in knockout mice. Histamine H(3) receptor antagonist JNJ-10181457-induced anxiety-like behaviours were dominantly reduced by zolantidine. Zolantidine significantly attenuated the discriminative stimulus effects of morphine.
