(1) a group represented by the formula: -Q(R1a)(R1b)(R1c)
whereinQ is a carbon atom, a silicon atom or a germanium atom, andR1a, R1b and R1c are each independently a substituent, orR1a and R1b in combination optionally form, together with the adjacent Q, an optionally substituted ring,(2) a neopentyl group, or(3) a trimethylsilylmethyl group, R2 is
(1) a group represented by the formula: whereinR5 is an optionally substituted alkyl group or an optionally substituted alkoxy group, andthe benzene ring in the formula optionally has additional substituent(s) besides R5,(2) an optionally substituted bicyclic fused heterocyclic group, or(3) a group represented by the formula: -L-Z1 whereinL is a bond or CH2, andZ1 is an optionally substituted non-aromatic ring group, R3 is a hydrogen atom or a substituent, and R4 is a substituent (provided that
(1) a group represented by the formula: whereinA1 is CRA1 wherein RA1 is a hydrogen atom or a substituent, or a nitrogen atom,A2 is CRA2 wherein RA2 is a hydrogen atom or a substituent, or a nitrogen atom,A3 is CRA3 wherein RA3 is a hydrogen atom or a substituent, or a nitrogen atom, orwhen A2 is CRA2 wherein RA2 is a substituent, and A3 is CRA3 wherein RA3 is a substituent, then RA2 and RA3 in combination optionally form, together with the carbon atoms that they are bonded to, a hydrocarbon ring or a heterocycle,R9 is a hydrogen atom or a hydroxy group, and when R9 is a hydroxy group, then A1l, A2 and A3 are CRA1, CRA2 and CRA, respectively, andR10 is a hydroxy group or an optionally substituted C1-6 alkoxy group, and(2) an optionally substituted C1-6 alkoxy group are excluded), or when R3 is a substituent, then R3 and R4 in combination optionally form, together with the nitrogen atom adjacent to R3 and the carbon atom adjacent to R4, an optionally substituted ring (provided that
(1) a cyclic group represented by the formula: wherein X is CH or a nitrogen atom, which is optionally further substituted, and(2) a cyclic group represented by the formula: are excluded), and the substituents that the ring optionally has optionally form a spiro ring, provided that 5-chloro-N-[1-cyclohexyl-2-oxo-2-[[4-[1-(1-pyrrolidinylmethyl)cyclopropyl]phenyl]amino]ethyl]-2-thiophenecarboxamide, α-(acetylamino)-N-[4-(trifluoromethyl)phenyl]-cyclopentaneacetamide, α-(acetylamino)-N-[4-(1,1-dimethylettyl)phenyl]-cyclopentaneacetamide, α-(acetylamino)-N-[2-bromo-4-(trifluoromethyl)phenyl]-cyclopentaneacetamide, and N-(4-tert-butyl-2-((5-ethyl-2-(2-ethyl-4,4-dimethylpentyl)-7,7-dimethyloctyl)oxy)phenyl)-2-(5,5-dimethyl-2,4-dioxo-1,3-oxazolidin-3-yl)-2-(2-octadecyl-1,1-dioxido-2H-1,2,4-benzthiadiazin-3-yl)acetamide are excluded, or a salt thereof. |
