Tiratricol (also known as TRIAC or triiodothyroacetic acid) is a thyroid hormone analogue, which has been studied since the 1950s. Tiratricol is used as a dietary supplement for thyroid problems including thyroid cancer. It is also used for increasing metabolic rate for weight loss, and reducing cellulite. In the US, the Food and Drug Administration (FDA) has determined that the product Triax (TRIAC, tiratricol) is not a dietary supplement but an unapproved new drug containing a powerful thyroid hormone, which may cause serious health consequences. The State of Missouri embargoed the product at its distributor (Syntrax) and the Utah-based manufacturer (Pharmatech) has agreed to stop distributing any product containing the ingredient TRIAC. The FDA has issued recalls for other tiratricol-containing products, including Tricana Metabolic Hormone Analogue, Tria-Cutz Thyroid Stimulator Dietary Supplement Capsules, and Sci-Fi-Tri-Cuts Dietary Supplement Capsules. Tiratricol is a prescription drug in France used for therapy of thyroid hormone resistance and therapy of thyroid cancer.

Sulfobromophthalein (BSP) is a dye with a high affinity for organic anion transporting polypeptides (OATPs) and has been used as a substrate for multidrug resistance associated protein 2 (Mrp2). BSP is transported into hepatocytes by OATPs and, after conjugation to glutathione, is excreted into bile by Mrp2.3 It was found to inhibit the aldo-keto reductase ARK1C20. Sulfobromophthalein (BSP) is used in diagnosis of hepatic disorders.It is also used for the quantitative determination of proteins.

Aescin, the major active principle from Aesculus hippocastanum (Hippocastanaceae) the horse chestnut tree, has shown satisfactory evidence for a clinically significant activity in chronic venous insufficiency (CVI), haemorrhoids and post-operative oedema. In one controlled trial aescin was shown to be as effective as compression therapy as an alternative to medical treatment for CVI. The therapeutic benefit is well supported by a number of experimental investigations in different animal models, indicative of clearcut anti-oedematous, anti-inflammatory and venotonic properties, mainly related to the molecular mechanism of the agent, allowing improved entry of ions into channels, thus raising venous tension in both in vitro and in vivo conditions. Other mechanisms, i.e. release of PGF2 from veins, antagonism to 5-HT and histamine, reduced catabolism of tissue mucopolysaccharides, further underline the wide ranging mechanisms of the therapeutic activity of aescin. Aescin exists in two forms, α and β. β-aescin (b-escin) appears to be the active component of the mixture and is the molecular form present in major available pharmaceutical products. Beta-aescin has cytotoxic activity toward human colon adenocarcinoma cell lines.

Trichlorfon (Metrifonate), the organophosphorous cholinesterase inhibitor, O,O-dimethylhydroxy-2,2,2-trichlorethyl-phosphonate, has been used sporadically in the treatment of human schistosomiasis for a decade. It has selective and variable schistosomicidal activity against S. haematobium that results from its partial metabolism to a highly active anti-cholinesterase, dichlorvos. Schistosomal cholinesterase is more susceptible to this metabolite than that of the human host, but transient reductions in both plasma and erythrocyte cholinesterase activity are demonstrable at therapeutic dosage. However, despite early concerns about its potential toxicity, metrifonate is well tolerated and has been used effectively and extensively in large-scale control programmes. Its potential to enhance central nervous system cholinergic neurotransmission led to clinical trials for the treatment of people with Alzheimer's disease (AD).

Manidipine, (R)- is enantiomer of Manidipine a lipophilic, third-generation dihydropyridine calcium channel antagonist with a high degree of selectivity for the vasculature, thereby inducing marked peripheral vasodilation with negligible cardiodepression. Manidipine has different pharmacological effects and (S)-manidipine is shown to be about 30–80 times more potent than (R)-manidipine in its antihypertensive action and in the radioligand binding assay. Patch-clamp experiments revealed that the S-enantiomers of manidipine displayed a faster onset of action and produced a greater blockade than the R-enantiomer. Also, manidipine enantiomers have markedly different pharmacokinetics and the S/R ratio for (S)- and (R)-enantiomer concentrations is 2.0

Ambucaine also known as Sympocaine (Win 3706) is a local anesthetic. It has been studied as an agent for spinal anesthesia.

Piprozolin is a choleretic drug. It was marketed under tradenames Probilin, Secrebil, Prozobil for the treatment of biliary-tract disorders and dyspepsia.
