A compound represented by the following general formula (1);
wherein X represents R1(R2)(R3)C— where R1 represents a C3-C8 cycloalkyl group, an optionally substituted C6-C14 aryl group, an optionally substituted heterocyclic residue, an optionally substituted C6-C14 aryloxy group, or an optionally substituted C7-C15 arylmethyl group; R2 and R3 independently represent hydrogen atom or a C1-C5 alkyl group, or R2 and R3 may combine to represent a C2-C7 alkylene group; or
X represents R7—A— wherein R7 represents (i) a C1-C10 alkyl group which may optionally be substituted with an optionally substituted C6-C14 aryl group, an optionally substituted fluorenyl group or an optionally substituted heterocyclic group, (ii) an optionally substituted C6-C14 aryl group or (iii) an optionally substituted heterocyclic group, and A represents an oxygen atom or —N—R8 where R8 represents hydrogen atom or a C1-C5 alkyl group,
Y represents an oxygen atom or a sulfur atom,
R4 and R5 independently represent hydrogen atom or a C1-C5 alkyl group; and R6 represents hydrogen atom, a C1-C5 alkyl group which may optionally be substituted with a hydroxyl group, a hydroxyl group or a C1-C5 alkoxy group,
provided that the compounds wherein R7 is a benzyl group, A and Y are an oxygen atom, R4 and R5 are hydrogen atom, and R6 is a propyl group are excluded, or a salt thereof, or a solvate thereof or a hydrate thereof.
