hypertonic saline
Any solution of sodium chloride (NaCl) in water with a concentration of NaCl higher than that found in physiological saline (0.9% w/v). When administered in vivo, hypertonic saline (HTS) exhbits several physiological effects beneficial to cerebral injury including: 1) osmotic and vasoregulatory - by promoting the flow of excess water from cerebral tissue to the blood via osmosis and decreasing edema in the vascular endothelium of injured tissues, thus lowering vascular resistance and allowing more blood flow; 2) hemodymanic - by effectively expanding plasma volume; 3) immunomodulatory - by preventing leukocytes from becoming activated and adhering to injured neurons and; 4) neurochemical - by counteracting detrimental excitatory amino acids through the normalization of neuronal cell membranes and by restoration of normal electrolyte and neurotransmitter levels in brain cells, and normal cell volumes. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

hypoxia-activated prodrug TH-302
An hypoxia-activated prodrug consisting of an indazole-based tubulin inhibitor conjugated with a hypoxic activator, such as a substituted nitroimidazole, with potential antineoplastic activity. When the hypoxia activator of hypoxia-activated prodrug TH-302 is activated by low oxygen concentrations in the hypoxic regions of tumors, the indazole-based tubulin inhibitor is released, which may result in the inhibition of tubulin polymerization in tumor cells and tumor cell mitotic arrest and death. Normoxic tissues are spared due to the hypoxia-specific release of the cyctotoxic moiety. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
