JS-K Usage And Synthesis
UsesJS-K is a NO donor that reacts with glutathione to generate NO at physiological pH. JS-K induces reactive oxygen species (ROS) to mediate apoptosis. JS-K induces autophagy. JS-K inhibits invasion. JS-K has a broad spectrum anti-proliferative activity in cancer cells. JS-K reduces tumor volume and causes necrosis of implanted tumors in mice[1][2].
Biochem/physiol ActionsJS-K belongs to the class of diazeniumdiolate prodrug. It generates nitric oxide when metabolized by glutathione S-transferases (GST), which ensures optimal activity of JS-K. It has tumor growth inhibition action in human prostate cancer and leukemia.
in vivo

JS-K (1.54 mg/kg; i.v.; three times/week for 15-20 days) reduces tumor volume and causes necrosis of implanted tumors in mice [1].

Animal Model:NOD/SCID mice (6-8 weeks) (injected in the flanks s.c. with HL-60 or PPC-1 cells)[1]
Dosage:1.54 mg/kg
Administration:Intravenous injection (i.v.), three times/week for 15-20 days
Result:Sixteen days after starting therapy, the average tumor volumes in vehicle and experimental group were 8.34 and 3.13 cm3, respectively, reflecting a > 50% reduction in tumor volume in experimental group.
Nineteen days after start of therapy, s.c. tumor implant volumes were 0.368 and 0.107 cm3 in vehicle and experimental group, respectively.
Revealed extensive cell necrosis in HL-60 (> 50%) and PPC-1 cell tumors.
Up to 1.54 mg/kg without observing significant hypotension, whereas doses of 1.54 mg/kg or higher has a notable hypotensive effect.
