Calculate Digit Verification of CAS Registry Number 173990-72:
(8*1)+(7*7)+(6*3)+(5*9)+(4*9)+(3*0)+(2*7)+(1*2)=172
172 % 10 = 2
So 173990-72-2 is a valid CAS Registry Number.

Synthesis of 4-N,N-dialkylaminoethyl-2-indolones as potential dopamine agonists

Namil, A.,Benoit-Guyod, M.,Leclerc, G.

, p. 973 - 982 (2007/10/03)

A set of fourteen 4-ethyl>-2-indolone analogues of dopamine were synthesized in 15 steps and evaluated for their affinities towards the D2 receptor using sulpiride or spiperone as radioligands.Six analogues displayed D2 agonist activities comparable (Ki = 450 - 650 nM) to Ropinirole or SK and F 101468.The functionalized amino side chain introduced in the 4-position can be used to modulate the lipophlicity of the analogues without significantly affecting D2 activity. - Keywords: lactam; indolone; rigid dopamine analogue; D2 receptor binding
