Nosantine racemate (NPT-15392 racemate)

Nosantine racemate is the racemate of Nosantine. Nosantine is an inducer of IL-2 or enhancer of IL-2 induction by phytohemagglutinin (PHA).

The purine immunoenhancing drug Nosantine (NPT 15392) is evaluated as an inducer of IL-2 or enhancer of IL-2 induction by phytohemagglutinin (PHA). Nosantine is found to has significant enhancing activity on PHA induction of IL-2 by human lymphocytes over a wide range of concentrations[1].

Multiple concomitant immune responses are assessed in individual rats following treatment with the immunoenhancing drugs, Isoprinosine (5 or 50 mg/kg), Nosantine (0.1 or 1.0 mg/kg) and Avridine (1 or 25 mg/kg), or the immunosuppressant, Cyclophosphamide (75 mg/kg). Rats treated with Nosantine (NPT 15392) have significantly enhanced DTH reactions at the 0.1 mg/kg dose. It can be concluded that NPT 15392 act as general immunostimulants in the rat, with avridine having the greatest effect under these experimental conditions[2].
