Abstract

Oxathiazin-like compounds, processes for making new oxathiazin-like compounds, compounds useful for making oxathiazin-like compounds, and their uses are disclosed. Processes of treating patients suffering from cancers, bacterial infections, fungal infections and/or viral infections by administering oxathiazin-like compounds are also disclosed. These compounds were found to have significantly longer half-life compared to taurolidine and taurultam.

Claims (22)

1. A method of reducing or inhibiting cancer cell migration in a subject in need thereof comprising administering an effective amount of a compound of formula I

wherein R is H, an alkyl, or benzyl, to the subject.

2. The method of claim 1 , wherein the compound is administered orally, intravenously, topically, or a combination thereof.

3. The method of claim 1 , wherein the compound is

4. The method of claim 1 , comprising administering 0.1 g to about 100 g of the compound per day.

5. The method of claim 1 , comprising administering 5 g to about 30 g of the compound per day.

6. The method of claim 1 , comprising administering the compound in a gel, capsule, tablet, or solution.

7. The method of claim 1 , comprising administering the compound in a pharmaceutical composition at a concentration of about 0.01 to about 3% w/v.

8. The method of claim 1 , comprising administering the compound in a pharmaceutical composition at a concentration of about 0.01 μg/ml to about 1000 μg/ml.

9. The method of claim 1 , comprising administering the compound in a pharmaceutical composition containing about 0.01 to about 3% taurolidine and/or taurultam.

10. The method of claim 1 , wherein the subject has a tumor, cancerous cells, pre-cancerous cells, or cancer stem cells, is suspected of having a tumor, cancerous cells, pre-cancerous cells, or cancer stem cells, or is at risk of developing a tumor, cancerous cells, pre-cancerous cells, cancer stem cells or metastases thereof.

11. A method of treating a subject having a squamous cell carcinoma comprising administering an effective amount of a compound of formula I
