Noscapine (also known as Narcotine, Nectodon, Nospen, Anarcotine and (archaic) Opiane) is a benzylisoquinoline alkaloid from plants of the poppy family, without painkilling properties. This agent is primarily used for its antitussive (cough-suppressing) effects. Noscapine is often used as an antitussive medication. A 2012 Dutch guideline, however, does not recommend its use for coughing. Noscapine can increase the effects of centrally sedating substances such as alcohol and hypnotics. Noscapine should not be taken in conjunction with warfarin as the anticoagulant effects of warfarin may be increased. Noscapine, and its synthetic derivatives called noscapinoids, are known to interact with microtubules and inhibit cancer cell proliferation. Mechanisms for its antitussive action are unknown, although animal studies have suggested central nervous system as a site of action. Furthermore, noscapine causes apoptosis in many cell types and has potent antitumor activity against solid murine lymphoid tumors (even when the drug was administered orally) and against human breast and bladder tumors implanted in nude mice. Because noscapine is water-soluble and absorbed after oral administration, its chemotherapeutic potential in human cancer merits thorough evaluation. Antifibrotic effect of noscapine based on novel mechanism, which it shows through EP2 prostaglandin E2 receptor-mediated activation of protein kinase A.

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.

Tribromsalan (trade name Temasept IV) is a member of brominated salicylanilides chemical family. Was initially registered in 1964 manufactured by Hexcel Corporation, Sherwin Williams Chemicals. It is a pesticide type with antimicrobial and preservative features found its application in hard surfaces, laundry, textiles, and manufactured products. Types of tribromsalan formulations include solid, solutions, and sprays and its usual carrier is soap. Limited exposure is possible based on the registered uses of these products as disinfectants, laundry additives, textile preservatives, and manufactured products and do not include direct application to a food or feed crop. In 1974 FDA directed the removal of tribromsalan drug products from the market because it was found to make skin extrasensitive to light. For the same reason it was forbidden in Europe since the 1970s. Since 1982 the OTC topical antimicrobial drug products rulemaking was reopened and included tribromsalan in a list of antimicrobial OTC Drug Products. At present tribromsalan is considered an antiseptic active ingredient eligible for the OTC use as a consumer antiseptic hand and body wash drug product. It was reported that tribromsalan, inhibits NF-kappaB signaling via inhibition of IkappaBalpha phosphorylation with IC50 of 7.9 uM. This finding provides new information on activities and mechanisms of action that may suggest mechanisms of potential novel applications in cancer treatment of such drugs as tribromsalan.

Berberine, an alkaloid isolated from Rhizoma Coptidis, is known to have a wide array of therapeutic effects including antimicrobial, antineoplastic, and hepatoprotective effects. It is found in several plants including European barberry, goldenseal, goldthread, Oregon grape, phellodendron, and tree tumeric. Berberine seems to slightly reduce blood sugar levels in people with diabetes. Berberine might lower blood pressure. Berberine is possibly safe for most adults for short-term use when taken by mouth or applied to the skin.
