Monoxerutin is a flavonol, a type of flavonoid. Monoxerutin is the vasodilator and antihaemorrhagic agent. It is used for the treatment of varicose veins and chronic venous insufficiency.

Promegestone (R 5020) is a potent progestin devoid of androgenic side-effects and has marked anti-estrogenic activity. Promegestone is an AChR noncompetitive antagonist that may alter AChR function by interactions at the lipid-protein interface. Promegestone is used in the treatment of gynecological disorders due to luteal insufficiency.

Vinpocetine is a synthetic derivative of the vinca alkaloid vincamine. Vinpocetine was first isolated from the plant in 1975 by the Hungarian chemist Csaba Szántay. The mass production of the synthetic compound was started in 1978 by the Hungarian pharmaceutical company Richter Gedeon. Vinpocetine has been reported to have cerebral blood-flow enhancing and neuroprotective effects, and has been used as a drug in Eastern Europe for the treatment of cerebrovascular disorders and age-related memory impairment. Vinpocetine acts as a phosphodiesterase (PDE) type-1 inhibitor in isolated rabbit aorta, Independent of vinpocetine's action on PDE, vinpocetine inhibits IKK preventing IκB degradation and the following translocation of NF-κB to the cell nucleus. Increases in neuronal levels of DOPAC, a metabolic breakdown product of dopamine, have been shown to occur in striatal isolated nerve endings as a result of exposure to vinpocetine. Such an effect is consistent with the biogenic pharmacology of reserpine, a structural relative of vinpocetine. However, this effect tends to be reversible upon cessation of vinpocetine administration, with full remission typically occurring within 3–4 weeks. Vinpocetine is generally well-tolerated in humans. No serious side effects have thus far been noted in clinical trials although none of these trials were long-term. Some users have reported headaches, especially at doses above 15 milligrams per day, as well as occasional upset stomach. The safety of vinpocetine in pregnant women has not been evaluated. Vinpocetine is not FDA approved in the United States for therapeutic use. The U.S. Food & Drug Administration (FDA) has ruled that vinpocetine, due to its synthetic nature and proposed therapeutic uses, was ineligible to be marketed as dietary supplement under the Federal Food, Drug, and Cosmetic Act (FDCA).

Gallium (Ga) is an element. It is a soft, slivery blue metal that becomes liquid (and silvery white) above room temperature. Gallium has been investigated for its anticancer properties since it was discovered that 67Ga(III) citrate injected in tumor-bearing animals localizes to tumor sites. Gallium has been investigated for treatment in multiple types of cancer (bladder cancer, lymphoma, multiple myeloma, paget's disease, and prostate cancer). Different generations of gallium salt are being evaluated for their antitumor efficacy and are in preclinical or clinical development. Gallium might also display antimicrobial activity, and is thought to disrupt iron homeostasis in certain bacteria and fungi.

Cropropamide is the main component of the drug Prethcamide, which is a respiratory stimulant to produce arousal from drug-induced depression. Prethcamide produces a marked increase in ventilation, primarily as a result of increased tidal volume, with minimal increases in respiratory rate. Prethcamide is marketed for parenteral and oral administration to humans in several European and South American countries but is not approved by the U.S. Food and Drug Administration for use in either human or veterinary medicine in the United States. Prethcamide is banned by several sports governing bodies, including the International Olympic Committee and the International Amateur Athletic Federation, because of its potential to stimulate the performance of athletes.

Vindesine (desacetyl vinblastine amide sulfate) is a synthetic derivative of vinblastine. Vindesine acts by causing the arrest of cells in metaphase mitosis through its inhibition tubulin mitotic funcitoning. Vindesine is an anti-neoplastic drug for intravenous use which can be used alone or in combination with other oncolytic drugs. Information available at present suggests that Eldisine as a single agent may be useful for the treatment of: acute lymphoblastic leukaemia of childhood resistant to other drugs; blastic crises of chronic myeloid leukaemia; malignant melanoma unresponsive to other forms of therapy; advanced carcinoma of the breast, unresponsive to appropriate endocrine surgery and/or hormonal therapy. Adverse effects associated with the use of vindesine include cellulitis and phlebitis, gastrointestinal bleeding, chills, and fever. It may increase the neuropathy associated with Charcot-Marie-Tooth syndrome. Vindesine may interact with mitomycin-C (brand name Mutamycin), causing acute bronchospasm within minutes or hours following administration. Phenytoin (brand name Dilantin) may also interact with vindesine, leading to decreased serum levels of phenytoin.

Cathine, known as D-norpseudoephedrine, is a psychoactive drug of amphetamine class, found naturally in Catha edulis (khat). It is a norepinephrine and dopamine releasing agent, and has thermogenic and anorectic effect. In the United States, cathine is classified as a Schedule IV controlled substance. Cathine hydrochloride is used as an appetite suppressant during the first few weeks of dieting to help establish new eating habits.

Viminol is an opioid analgesic developed by the company Zambon. It is marketed under tradename Dividol for the treatment of pain due to various causes, including the treatment of pain due to osteoarthritis, neuritic pain, vascular pain, visceral pain, neoplastic pain, and pain due to other sources. In vivo studies demonstrated that the analgesic effects of viminol depend on the stereo configuration: the R,R-enantiomer exhibit agonistic activity, while the S,S-enantiomer produce the opposite effect.

Rhodium is a hard, shiny, silvery metal. The major use of rhodium is in catalytic converters for cars (80%). It reduces nitrogen oxides in exhaust gases. Rhodium is also used as catalysts in the chemical industry, for making nitric acid, acetic acid and hydrogenation reactions. It is used to coat optic fibres and optical mirrors, and for crucibles, thermocouple elements and headlight reflectors. It is used as an electrical contact material as it has a low electrical resistance and is highly resistant to corrosion. Rhodium is a rare element with no known natural biological function. Rhodium complexes show diverse biological activities against various targets, including enzymes and protein-protein interactions. Dimeric mu-Acetato dimers of rhodium(II) as well as monomeric square planar rhodium(I) and octahedral rhodium(III) complexes have shown interesting antitumor properties. On the other hand, rhodium is a suspected carcinogen.
