4-Methoxyamphetamine (Para-methoxyamphetamine, PMA) is a synthetic drug chemically similar to the recreational drug 3,4-methylenedioxymethamphetamine (MDMA or "ecstasy") and often replaces MDMA in tablets. Numerous cases of intoxication have been documented and fatal cases involving PMA have been described. PMA induces toxicity at lower doses than MDMA. Clinical symptoms specific to PMA poisoning include life-threatening hyperthermia, breathing difficulties, tachycardia, rhabdomyolysis, and acute renal failure. In the scarce studies conducted in laboratory animals, PMA has shown cardiovascular alterations in dogs, hyperthermia on a high ambient temperature, hallucinogen properties, and disruption of operant behavior in rats. A slight motor activity stimulation, lower than that induced by MDMA, has also been reported. The effects of PMA on brain neurotransmission are similar to those of MDMA, thus, PMA increases serotonin (5-hydroxytryptophan or 5-HT) release from the synaptic terminal and blocks its reuptake; it also acts upon noradrenergic and dopaminergic terminals but in a lesser proportion, and can also delay the metabolism of these monoamines by inhibition of monoamine oxidase (MAO)
Indacaterol is an ultra-long-acting beta-adrenoceptor agonist developed by Novartis. It was approved by the European Medicines Agency (EMA) under the trade name Onbrez Breezhaler on November 30, 2009, and by the United States Food and Drug Administration (FDA), under the trade name Arcapta Neohaler, on July 1, 2011. It needs to be taken only once a day, unlike the related drugs formoterol and salmeterol. It is licensed only for the treatment of chronic obstructive pulmonary disease (COPD) (long-term data in patients with asthma are thus far lacking). It is delivered as an aerosol formulation through a dry powder inhaler.

Didanosine was developed by Bristol-Myers Squibb in collaboration with the NIH for the treatment of HIV-1 infections. Upon administration the drug is metabolized to the active metabolite which inhibits HIV-1 reverse transcriptase both by competing with deoxyadenosine 5'-triphosphate and by its incorporation into viral DNA. Didanosine was approved by FDA under the name Videx (among the other names).
Thiabendazole (TBZ, trade names Mintezol, Tresaderm, and Arbotect) was first introduced in 1962. This drug is a fungicide and parasiticide and is indicated for the treatment of: strongyloidiasis (threadworm), cutaneous larva migrans (creeping eruption), visceral larva migrans, trichinosis: relief of symptoms and fever and a reduction of eosinophilia have followed the use of this drug during the invasion stage of the disease. But usage of this drug was discontinued. The precise mode of action of thiabendazole on the parasite is unknown, but it may inhibit the helminthspecific enzyme fumarate reductase. It was shown, also that thiabendazole reversibly disassembles newly established blood vessels, marking it as vascular disrupting agent (VDA) and thus as a potential complementary therapeutic for use in combination with current anti-angiogenic therapies. Was shown, that vascular disruption by TBZ results from reduced tubulin levels and hyper-active Rho signaling. In addition, was confirmed, that thiabendazole slowed tumor growth and decreased vascular density in preclinical fibrosarcoma xenografts and thus, it could lead directly to the identification of a potential new therapeutic application for an inexpensive drug that is already approved for clinical use in humans.
