Iranian researchers have produced�a nano-drug which has proven effective in battling treatment resistant cancers.

The Cancer Research Center�of�Tehran University of Medical Sciences produced the polymer-based nanocarrier for the targeted release of the anti-cancer drug curcumin, ISNA reported on Sunday.
�This nanocarrier was made�without the use of poisonous catalysts and has proven successful�in clinical trials on a number cancer patients,� �said Dr Ali Mohammad Alizadeh from the Iran Nanotechnology Initiative Council.
Research has proven that curcumin, which is found in turmeric, has anti-cancer and cancer preventing properties�apart from its anti-oxidant and anti-inflammatory properties, he added.

When curcumin is prescribed in its edible form, it has a low effect on the targeted tissues because of its low absorption rate and fast metabolism which causes it to be flushed from the body, he noted.

However, by capsuling curcumin in nano-emulsions (nano�curcumin) its medical properties increase, Alizadeh�noted.

Even if prescribed�in high dosages, the drug is�proven not poisonous during first-stage clinical trials and is currently near the end of stage two clinical trials on drug-resistant breast and digestive tract cancers.

Alizadeh added that because all the basic materials required to manufacture nano-curcumin are available in the country it can be domestically mass-produced as an anti-cancer drug.
