Altrenogest (INN, USAN, BAN) (brand name Regumate), also known as allyltrenbolone, is a steroidal progestin that is widely used in veterinary medicine to suppress estrus in animals. Altrenogest is an orally active progestin developed for use in the horse. Altrenogest has been chemically modified by addition of a hydroxyl group and 3 carbon chain placed on carbon 17 of the progestin. Research has demonstrated that Altrenogest has low anabolic activity and is 20 times less potent than testosterone or similar progestins when compared for effects on muscle growth in castrated rats

Beta-methyl digoxin (beta-methyl digoxin; Metildigoxin (INN, or medigoxin BAN, or methyldigoxin) is a methyl derivative (methyl group in position 4 of the digitoxose residue) of digoxin is a cardiac glycoside, a type of drug that can be used in the treatment of congestive heart failure and cardiac arrhythmia (irregular heartbeat). The substance is closely related to digoxin; it differs from the latter only by an O-methyl group on the terminal monosaccharide.

Bambuterol is an active precursor of the selective beta2-adrenergic agonist terbutaline. Bambuterol is the bis-N,N-dimethyl-carbamate of terbutaline. Bambuterol is a remarkably selective and potent inhibitor of cholinesterase. BAMBEC (Bambuterol hydrochloride) oral solution or tablets are indicated for the management of asthma, bronchospasm and/or reversible airways obstruction.

Procaterol is a beta2-adrenoreceptor agonist. It is a bronchodilator that may be administered orally or by aerosol inhalation for the treatment of dyspnea caused by bronchial asthma, chronic bronchitis, and pulmonary emphysema. The drug is not approved in the USA, but is available in Japan, Indonesia, and other countries worldwide.

Hexoprenaline is a selective beta2-adrenoreceptor agonist indicated for use in the treatment of bronchospasm associated with obstructive airways diseases, including asthma, bronchitis and emphysema. In many countries the drug is used as tocolytic agent (under the trade name gynipral).

Xamoterol (ICI 118,587) is a partial agonist of beta1-adrenoceptors. Xamoterol acts on the cardiac beta 1-adrenergic receptor, modifies the response of the heart to variations in sympathetic activity. At rest, it produces modest improvements in cardiac contractility, relaxation, and filling without increase in myocardial oxygen demand. The improvements are maintained during exercise although the attendant tachycardia is attenuated. The beneficial effects of xamoterol on both systolic and diastolic function suggested that it would be effective in patients with mild-to-moderate heart failure, and this was demonstrated in small placebo-controlled studies where effort tolerance and symptoms were improved. Xamoterol produced improvements in exercise capacity, clinical signs, symptoms and quality of life with a low incidence of adverse experiences. Xamoterol is effective as monotherapy in heart failure.

Denopamine is a selective agonist of beta-1 adrenergic receptor. The drug was approved in Japan under the name Kalgut for the treatment of chronic heart failure.

Acetyl-11-keto-beta-boswellic acid (AKBA), a pentacyclic triterpene, is a component of gum resin of Boswellia serrata. It inhibits 5-lipoxygenase in a selective, enzyme directed, non-redox, and noncompetitive manner. In addition, AKBA inhibited topoisomerase I. It induces apoptosis and exerts antineoplastic properties. 5-LOXIN, a dietary supplement ingredient (Boswellia serrata extract enriched with 30% 3-O-acetyl-11-keto-beta-boswellic acid) is effective in reducing pain and improving physical functioning in osteoarthritis patients.

Glucosamine is an amino sugar and a prominent precursor in the biochemical synthesis of glycosylated proteins and lipids. Glucosamine is part of the structure of the polysaccharides chitosan and chitin, which compose the exoskeletons of crustaceans and other arthropods, as well as the cell walls of fungi and many higher organisms. Glucosamine is one of the most abundant monosaccharides. It is produced commercially by the hydrolysis of crustacean exoskeletons or, less commonly, by fermentation of a grain such as corn or wheat. Evidence for the effectiveness of glucosamine supplements is mixed. In the United States, it is one of the most common non-vitamin, non-mineral, dietary supplements used by adults. Glucosamine is marketed to support the structure and function of joints, and the marketing is targeted to people suffering from osteoarthritis. Commonly sold forms of glucosamine are glucosamine sulfate, glucosamine hydrochloride, and N-acetylglucosamine. Of the three commonly available forms of glucosamine, only glucosamine sulfate is given a "likely effective" rating for treating osteoarthritis. Glucosamine is often sold in combination with other supplements such as chondroitin sulfate and methylsulfonylmethane. Glucosamine, along with commonly used chondroitin, is not routinely prescribed to treat people who have symptomatic osteoarthritis of the knee, as there is insufficient evidence that this treatment is helpful. As is common with heavily promoted dietary supplements, the claimed benefits of glucosamine are based principally on clinical and laboratory studies. Clinical studies are divided, with some reporting relief from arthritic pain and stiffness, while higher quality studies report no benefit above placebo. There is no evidence to date that consumption of glucosamine by sport participants will prevent or limit joint damage after injury. In a randomized placebo-controlled trial, glucosamine supplementation had no additional effect on any rehabilitation outcome when given to athletes after anterior cruciate ligament (ACL) reconstruction. Glucosamine is naturally present in the shells of shellfish, animal bones, bone marrow, and fungi. D-Glucosamine is made naturally in the form of glucosamine-6-phosphate, and is the biochemical precursor of all nitrogen-containing sugars. Specifically in humans, glucosamine-6-phosphate is synthesized from fructose 6-phosphate and glutamine by glutamine—fructose-6-phosphate transaminase as the first step of the hexosamine biosynthesis pathway. The end-product of this pathway is uridine diphosphate N-acetylglucosamine (UDP-GlcNAc), which is then used for making glycosaminoglycans, proteoglycans, and glycolipids. As the formation of glucosamine-6-phosphate is the first step for the synthesis of these products, glucosamine may be important in regulating their production; however, the way that the hexosamine biosynthesis pathway is actually regulated, and whether this could be involved in contributing to human disease remains unclear.
