The present invention has as its object providing substituted phenethylamine derivatives that function as a motilin receptor antagonist and which are useful as medicines.
The invention provides compounds of Formula (1):
wherein:
Cy is a group of Formula (2):
an optionally substituted heterocyclic ring, C3-7cycloalkyl or phenyl;
R1, R2, R3, R4 and R5 are hydrogen, halogen, hydroxy, amino, trifluoromethyl or nitrile and at least one of R1, R2, R3, R4 and R5 is halogen, trifluoromethyl or nitrile;
R6 is hydrogen, optionally substituted straight-chained or branched C1-3alkyl, amino or hydroxy;
R7 is hydrogen, optionally substituted straight-chained or branched C1-3alkyl, optionally substituted amino or hydroxy;
R8 is hydrogen, methyl or ethyl;
R9 is optionally substituted straight-chained or branched C1-6alkyl, optionally substituted straight-chained or branched C2-6alkenyl, optionally substituted straightchained or branched C2-6alkynyl, C3-7cycloalkyl or optionally substituted phenyl;
R20 is hydrogen or straight-chained or branched C1- 3alkyl or R9 and R20 may together form C3-7cycloalkyl;
R10 is hydrogen or straight-chained or branched C1- 3alkyl;
R11 is hydrogen, optionally substituted straight-chained or branched C1-3alkyl, -CO-N(R14)R15, carboxyl or an optionally substituted heterocyclic ring;
R12 is hydroxy or -OR16;
R13 is hydrogen, straight-chained or branched C1- 6alkyl, straight-chained or branched C2-6alkenyl, straight-chained or branched C2-6alkynyl or a group of Formula (3):
R14 and R15, which may be the same or different, are hydrogen, optionally substituted straight-chained or branched C1-4alkyl, C3-7cycloalkyl, straight-chained or branched C1-4alkyloxy, straight-chained or branched C1-4alkylsulfonyl or a heterocyclic ring, or R14 and R15, as -N(R14)R15, form optionally substituted 3- to 7-membered cyclic amine;
R16 is straight-chained C1-4alkyl;
R17 is hydrogen or methyl;
R18 and R19 together form cycloalkyl or C3-7cycloalkenyl ;
X is carbonyl or methylene;
Y is carbonyl or methylene;
provided that
when Cy is 3-indolyl,
(i) R11 is an optionally substituted heterocyclic ring; or
(ii) R6 is hydrogen, R7 is amino, R8 is methyl, R9 is isopropyl, R20 is hydrogen, R10 is methyl, R11 is carbamoyl, R12 is hydroxy, R13 is tert-butyl, X is carbonyl and Y is carbonyl, and
when Cy is cyclohexyl or phenyl, R11 is an optionally substituted heterocyclic ring;
or a hydrate or pharmaceutically acceptable salt thereof.
