Podophyllotoxin is chemically

Podofilox is a pure, stabilized form of podophyllin, in which only the biologically active portion of the compound is present. Podophyllotoxin is a toxic, polycyclic antimitotic agent isolated primarily from the rhizome of the plant Podophyllum peltatum. This agent is formulated for topical applications. (NCI04 From Wikipedia, the free encyclopedia Podophyllotoxin (PPT) is the active ingredient in Podofilox, which is a medical cream that is used to treat genital warts and molluscum contagiosum. It is not recommended in HPV infections without external warts. It can be applied either by a healthcare provider or the person themselves Podophyllotoxin is an antimitotic. It acts by preventing viral wart cells from dividing and multiplying. Eventually all the wart cells die and new healthy cells grow in their place. For centuries, Native American tribes used the plant and its root for its medicinal, as well as poisonous, properties

The Chemical and Biological Route from Podophyllotoxin Glucoside to Etoposide: Ninth Cain Memorial Award Lecture Hartmann F. Stähelin and Albert von Wartburg Cancer Res January 1 1991 (51) (1) 5-15 The Chemical and Biological Route from Podophyllotoxin Glucoside to Etoposide: Ninth Cain Memorial Award Lecture1 Hartmann F. Stähelinand Albert von Wartburg Preclinical Research, Sando: Pharma AG, CH-4002 Basel, Switzerland The course of events which led to etoposide is an example of a development which started from a long-known natural co Consequently, podophyllotoxin arrests the cell cycle in the metaphase (Ayres and Loike, 1990, Buss and Waigh, 1995, Gordaliza et al., 2000). Moreover, podophyllotoxin is a specific cell cycle toxic agent, which inhibits the activity of type II topoisomerase, an essential nuclear enzyme at the G2 phase and S phase of a cell cycle Podophyllotoxin is a chemical taken from podophyllum. Podophyllotoxin (podofilox, Condylox) is an FDA-approved drug. Podophyllotoxin might be more effective than podophyllum and is less toxic. Report Problems to the Food and Drug Administratio

Synthesis of (-)-Podophyllotoxin (-)-Podophyllotoxin 1 and its derivative etoposide 2, derived from natural sources, are in current clinical use.Michael Sherburn of Australian National University reports (J. Am. Chem. Soc. 2003, 125, 12108.) complementary total syntheses of 1 and of its enantiomer. The key step in each of these syntheses is a spectacular intramolecular alkene arylation. It is chemically similar to the anti-cancer drug teniposide, being distinguished only by a methyl group where teniposide has a thienyl. Both these compounds have been developed with the aim of creating less toxic derivatives of podophyllotoxin. The substance is a white to yellow-brown, crystalline powder. It is soluble in organic solvents Podocon-25® is composed of Podophyllin (Podophyllum Resin, American) 25% in Benzoin Tincture. Podophyllum Resin is the powdered mixture of resins removed from the May apple or Mandrake (Podophyllum peltatum Linne'), a perennial plant of northern and middle United States (1) We have designed a polymer conjugate delivery system for a chemotherapeutic drug podophyllotoxin (PPT) by covalently conjugating PPT and polyethylene glycol (PEG) with acetylated carboxymethyl cellulose to yield conjugates containing various amounts of PPT and PEG

VP16-213, a semi-synthetic derivative of podophyllotoxin, is an effective antitumor agent in the treatment of a variety of leukemias and solid tumors Podophyllotoxin is too toxic for use as an anticancer agent, but medicinal chemical studies led to the development of etoposide (31) and teniposide (32) as podophyllotoxin analogs. They differ chemically from podophyllotoxin in their stereochemistry and glycosylation at C4 as well as being demethylated at C4', but their most significant.

  2. Podofilox (podophyllotoxin) is a patient-applied antimitotic drug that causes wart necrosis. Podofilox solution (using a cotton swab) or podofilox gel (using a finger) should be applied to anogenital warts twice a day for 3 days, followed by 4 days of no therapy. This cycle can be repeated, as necessary, for up to four cycles
  3. Podophyllotoxin cream (0.5%) is reliable as a home therapy for men but is not recommended for pregnant women because of presumed toxicity to the fetus. Each lesion must be treated individually as the therapeutic effect is localized. Other options for topical therapy include iodine and salicylic acid, potassium hydroxide, tretinoin, cantharidin.
  4. Although podophyllotoxin (and previously the cruder podophyllin) is a standard treatment for anogenital warts, its evaluation in cutaneous warts has been limited. The assumption is that penetration of the thick, cornified layer of cutaneous warts is poor compared with that achieved at mucosal sites

Cantharidin is a vesicant that causes a blister to form on the wart or growth. This action lifts the wart off the skin and after a few days when the blister has dried the wart will come off. The action of cantharidin does not go beyond the epidermal cells, the basal layer remains intact hence no scarring. Cantharidin is sometimes effective in. The Chemical Shift of Protons Connected to Heteroatoms. The second group of protons giving signal in this region is the ones bonded to heteroatoms such as oxygen and nitrogen. And even though the signal can be in the range from 1-6 ppm, it is usually in the downfield end of this spectrum.. This is due to the higher electronegativity of those atoms pulling the electron density and deshielding.
