or a salt thereof, wherein:
Y2 is CR2;
Y3 a bond;
Y4 CR4;
Y5 is N;
Y6 is N;
R1a is phenyl, which is optionally substituted with one or more R7;
R1b and R2, together with the intervening atoms, combine to form
an unsubstituted 6-membered heterocycloalkyl;
R3 is chosen from hydrogen and alkyl;
R4 is chosen from hydrogen and halo;
R5 hydrogen;
R5b is chosen from phenyl and pyridyl, either of which is optionally substituted with one or more R10;
each R7 is independently chosen from halo, cyano, hydroxy, alkyl, alkoxy, haloalkyl, hydroxyalkyl, cyanoalkyl, alkoxyalkyl, alkoxyalkoxyalkyl, aminoalkyl, acylaminoalkyl, (haloalkyl)aminoalkyl, alkylsulfonylaminoalkyl, arylalkyl, heteroarylalkyl, haloalkoxy, heteroaryl optionally substituted with alkyl, and heterocycloalkyl optionally substituted with alkyl, or
two or more R7, together with the intervening atoms, can form a heterocycloalkyl or heteroaryl;
and
each R10 is independently chosen from alkyl, haloalkyl, amino, aminoalkyl, aminocarbonyl, alkoxy, haloalkoxy, cyano, halo, and hydroxy.
