The title compound, C(21)H(21)N(3)O(3), was synthesized by a multi-component 1,3-dipolar cyclo-addition of azomethine ylide, derived from isatin and proline by a deca-rboxylative route, and (E)-1-phenyl-2-nitro-propene. In the mol-ecule, the spiro junction links a planar oxindole ring and a pyrrolidine ring in an envelope conformation. The mol-ecular packing is stabilized by an inter-molecular ...

Objective: Leptin, the product of ob gene, is important in control of appetite in humans. The objective was to determine the pre and post serum leptin levels in patients with ESRD (undergoing hemodialysis), to compare the pre serum leptin levels in patients with ESRD and normal healthy controls and to determine the serum IL-6 levels among patients with ESRD before and after hemodialysis. Method...
