Diphemanil methylsulfate (Prantal), a quarternary amine, is a highly specific parasympathetic blocking agent.

Khellin is a crystalline extract of a crude drug, which has long been used in Egypt for the treatment of ureteral colic. It is used in the management of bronchial asthma and angina pectoris. Interest in khellin as an adjunct to ultraviolet (UV) light therapy in the treatment of vitiligo is based on the structural similarity between khellin and the psoralens. Success has been reported using oral and topical khellin in clinical studies but it is not likely that khellin will be approved for the treatment of vitiligo. Unwanted side effects of khellin include dizziness, reversible cholestatic jaundice, pseudoallergic reaction, and elevated levels of liver enzymes (transaminases and gamma-glutamyltransferase).

Methoxyphenamine also known as 2-methoxy-N-methylamphetamine (OMMA), is a beta adrenergic receptor agonist nd is used as a bronchodilator to treat asthma, chronic obstructive pulmonary disease (COPD) and postinfectious cough. In addition, methoxyphenamine using is prohibited in sports according to the regulations of the World Anti-Doping Agency (WADA).

Adenosine monophosphate (AMP) is a nucleotide, consisting of a phosphate group, the sugar ribose, and the nucleobase adenine. AMP is an activator of several enzymes in the tissues. In the glycolytic pathway, the enzyme phosphofructokinase is inhibited by ATP but the inhibition is reversed by AMP, the deciding factor for the reaction being the ratio between ATP and AMP. In medicine, AMP is used mainly as an alternative to adenosine for treatment of ischemia and as a tool compound to measure hyperresponsiveness of airways.

TRICHOLINE CITRATE is indicated for the treatment and management of hepatic disorders and asthma symptoms in adults. It exerts lipotropic action in the hepatic cells. It also can lower the symptoms of asthma and reducing the pro-inflammatory and inflammatory mediators of the leukotriene pathway.

Adrenalone is a keton form of the natural substrate epinephrine. Adrenalone is evidently formed in vivo by hydrolytic cleavage of the diester by esterases. It is an adrenergic receptor agonist. Adrenalone inhibits the norepinephrine synthesis and dopamine beta oxidase. It is known to have very weak sympathomimetic activity when compared to adrenaline. Adrenalone has the high radioprotective effect. It is a topical nasal decongestant. Adrenalone has hemostatic, sympathomimetic and vasoconstrictor therapeutic functions.

Antipyrine is an analgesic and antipyretic that has been given by mouth and as ear drops. It is often used in testing the effects of other drugs or diseases on drug-metabolizing enzymes in the liver. It inhibits cyclooxygenases and shows little anti-inflammatory activity. Like many old and approved substances after almost 100 years of use, antipyrine has been associated with some serious side effects, namely agranulocytosis and shock reactions.

There is not much available information about thenyldiamine, is known, that it is used as antihistamine and for the treatment of asthma and bronchitis.

Angelicin (isopsoralen), is a furocoumarin, occuring in a number of plants belonging to the Umbelliferae family. It acts as a photosensitizer by forming DNA monoadducts. Angelicin is able to inhibit monoamine oxidase (MAO) activities in rat brain mitochondria. Angelicin exerts antineoplastic and antidiabetic properties in animal models.

Vasicinone is a quinazoline alkaloid. Hepatoprotective activity of vasicinone has being shown in mice. Pre-treatment with vasicinone and silymarin (25 mg/kg/day for 7 days) significantly decreased CCl4-induced increase in SGOT, SGPT, ALP levels. Vasicinone has shown cytotoxic and antiproliferative activity in several tumor cell lines. Vasicinone, an oxidation product of vascinine is a potent bronchodialator. Vasicinone could be utilised in alternate anti asthmatic therapy, since it plays a vital role in scavenging Nitric oxide which could prevent the bronchial inflammation in asthmatic patients.
