Arsenic as a chemical element (symbol As) occurs in many minerals, usually in conjunction with sulfur and metals, and also as a pure elemental crystal. Arsenic trioxide (As2O3) can be generated via routine processing of arsenic compounds including the oxidation (combustion) of arsenic and arsenic-containing minerals in air.
2 As2S3 (orpiment)+ 9 O2 → 2 As2O3 + 6 SO2
Although As2O3 (or As2O6) was developed and used as an anti-cancer therapeutic, it is not popular because of its severe toxicities.
Kominox is a relatively safe drug with very high water solubility compared with arsenic trioxide.
According to X-ray crystallography data, these two materials have completely different molecular structures.

· Early stage cancer cells are sometimes short-lived due to the erosion of telomeres caused by rapid cell division
· Such shortening of telomeres causes cancer cells to die prematurely and be eliminated
· However, malignant cancer cells produce telomerase, which is an enzyme that inhibits telomere shortening, allowing cancer cells continue to grow and
· Thus, telomerase is a key factor in cancer pathology and KOMIPHARM considers telomerase to be an important target in cancer therapy
· KOMIPHARM’S new drug (NaAsO₂) eliminates cancer cells by selectively binding to telomeres of cancer cells
· NaAsO₂ can treat cancer with minimal side effects because of its special molecular structure and high affinity for cancer cells with characteristically
shortened telomeres, while healthy cells are unaffected (Telomeric Sequences and Erosion paper)

· Current cytotoxic anticancer agents primarily kill mature cancer cell populations but cannot eradicate cancer stem cells.
As a result, the cancer recurs in the form of metastatic cancer and the tumor consists of more aggressive cancer stem cells.
· In order to treat metastatic cancer, a therapeutic agent capable of removing both mature cancer cells and cancer stem cells is essential.
· Scientific studies have shown that the role of cancer stem cells in the occurrence of metastatic cancer is close to 100%.
· Kominox, which we are developing, has the ability to kill 99% of the cancer stem cells of metastatic cancers metastasized from cancer cells sensitive to primary cancers.
