TrioxBio's API, S-ethylisothiouronium diethylphosphate, MTR-104 (MTR- 105), is a nitric oxide synthase (NOS) inhibitor which blocks the production of nitric oxide, preventing the dilation of blood vessels and the other detrimental effects caused by excessive NOS activity. MTR-105, a fast-acting synthetic NOS inhibitor with rapid onset of action when administered parenterally, has been effective in alleviating hypotension experimentally and in several observational studies while reducing NO production. MTR-105 is registered and approved for clinical use in the Republic of Moldova where data have been collected from 434 patients exposed to the drug in pre- and postapproval clinical investigations.

Potassium cation K-42 is a radioactive tracer. It was used to study K exchanges across the myocardial cell wall and measuring uptake of isotope by the myocardium, to measure of potassium ion influx in Chinese hamster ovary (CHO) cells and other researches related to K-transport in vivo and in vitro.

Chromic Phosphate Cr-51 is a radiopharmaceutical compound that has been extensively used in nuclear medicine. When administered intraperitoneally, the particulate form of chromic phosphate is pocketed in various areas of the peritoneum, or filtered out by the first lymph nodes encountered, because of the too large particle size, whereas the colloidal form is carried over to the lymphatic system. The larger particles originally present in its size spectrum or formed in vivo by aggregation of smaller particles are trapped by the first line of lymph nodes, and the remainder goes into the thoracic duct, with posterior incorporation into the blood circulation and final removal by the reticuloendothelial system: liver, spleen and bone marrow.
