Chlorproguanil is a biguanide. Chlorproguanil is active against P. falciparum and P. malariae. Chlorproguanil acts by inhibition of dihydrofolate reductase after cytochrome P450-catalysed cyclization. Chlorproguanil combined with dapsone was developing for the treatment of falciparum malaria. The anti-malarial combination chloroproguanil and dapsone has been withdrawn following demonstration of post-treatment haemolytic anaemia in glucose-6-phosphate dehydrogenase (G6PD) deficient patients in a phase III clinical trial.

Drofenine, product name Spasmo-Cibalgin (Novartis, Oman), is an antispasmodic/anticholinergic agent used for relaxing smooth muscle, treating dysmenorrhea, and relieving pain in the gastrointestinal tract, biliary passages, and urogenital tract. The possible therapeutic effect of drofenine is proposed by its activation of transient receptor potential vanilloid-3 (TRPV3), a member of the TRPV subfamily of TRP ion channels.

Tosufloxacin is a fluoroquinolone antibacterial agent. Tosufloxacin is an inhibitor of bacterial DNA gyrase and topoisomerase IV. Tosufloxacin is indicated for the treatment of various infections such as skin, respiratory, urinary, gynecologic, ophthalmologic, otolaryngologic, dental infections. Fluoroquinolones including tosufloxacin have a potential risk of inducing cartilage and joint toxicity in children. It is also associated with severe thrombocytopenia and nephritis, and hepatotoxicity.

Cis-4-methoxycinnamic acid is a less frequent isomer of 4-methoxycinnamic acid, isolated from from Aquilegia vulgaris.

(R)-Timolol is the (R)-enantiomer of non-selective Beta antagonist Timolol. (R)-Timolol is a ß-adrenergic blocking agent that binds only to nonspecific sites in the particulate fraction of the heart, lungs, and brain. (R)-Timolol is an antihypertensive agent that increases ocular blood flow and reduces intraocular pressure. (R)-Timolol is one of the impurities in commercial formulation of (S)-Timolol.

Cytarabine ocfosfate (commercial name: Starasid) is a prodrug having stearyl group attached to phosphoric acid at 5' position of arabinose moiety of cytosine arabinoside (Ara-C). This drug is given orally. The mode of action is in the inhibition of DNA synthesis after conversion to Ara-CTP as in Ara-C. The drug is metabolized in the liver, producing the intermediate metabolite, C-C3PCA which is converted to Ara-C gradually. This property results in the maintenance of relatively long time the blood Ara-C levels. This was proved to be active clinically against acute leukemia and MDS.

Ligustrazine (tetramethylpyrazine) is a bioactive ingredient extracted from the widely-used Chinese herb, Chuanxiong. It inhibits of platelet aggregation, enhances of vessel dilation, increases cerebral blood flow and possesses neuroprotective properties. The injection solution of ligustrazine has been used especially in China to treat ischemic stroke, coronary heart disease, diabetic nephropathy, and knee osteoarthritis. Ligustrazine was also evaluated in clinical as a remedy for pressure sores, as a salvage agent for patients with non-Hodgkin's lymphoma, as a treatment for bronchial asthma and vertebrobasilar insufficiency.
