, (2008/06/13)
An oxindole of Formula 1 or a prodrug thereof, or a pharmaceutically acceptable salt thereof is useful for growth hormone releaser: wherein R1, R2, R3and R4are independently hydrogen, optionally substituted alkyl etc; R5is optionally substituted aryl or optionally substituted heteroaryl; Z is —O— or —NH—; one of W1and W2is hydrogen, alkyl or —Y—CON(R10)R11; the other of W1and W2is n is 1, 2 or 3; m is 0, 1, 2 or 3; Y is single bond or C1-C3alkylene; R6and R7are independently hydrogen, optionally substituted alkyl etc; R8and R9are independently hydrogen, optionally substituted alkyl etc; R10and R11are independently hydrogen, alkyl etc.

A series of substituted oxindole derivatives was synthesized and evaluated for growth hormone (GH) releasing activity using cultured rat pituitary cells. (+)-6-Carbamoyl-3-(2-chlorophenyl)-(2-diethylaminoethyl)- 4-trifluoromethyloxindole (SM-130686, 37S) was found to have potent activity (EC50 = 3.0 nM), while the other enantiomer 37R had reduced activity. The absolute configuration of 37S was confirmed by X-ray crystallographic analysis. Compound 37S showed a good pharmacokinetic profile in rats with 28% oral bioavailability at 10 mg/kg and excellent in vivo activity as evidenced by a significant weight gain after 4 days of oral administration at 10 mg/kg twice a day. Compound 37S displaced the binding of 35S-MK-677 to human GHS-R with an IC50 value of 1.2 ± 0.2 nM.
