Provided herein are Heteroaryl Compounds of formula (I):
wherein R
1
and R
2
are as defined herein, compositions comprising an effective amount of a Heteroaryl Compound and methods for treating or preventing inflammatory conditions or cancer, and conditions treatable or preventable by inhibition of a kinase or a kinase pathway comprising administering an effective amount of a Heteroaryl Compound to a subject in need thereof.
An object of the present invention is to provide to a compound and a pharmaceutical composition, which have excellent Syk-inhibitory activity. The present invention provides a nicotinamide derivative represented by the following formula (I) (wherein R
1
represents a halogen atom; R
2
represents a C
1-12
alkyl group, a C
2-12
alkenyl group, a C
2-12
alkynyl group, a C
3-8
cycloalkyl group, an aryl group, an ar-C
1-6
alkyl group or a heterocyclic group, each optionally having at least one substituent; R
3
represents an aryl group or a heterocyclic group each optionally having at least one substituent; and R
4
and R
5
each independently represent a hydrogen atom; and R
2
and R
4
may form a cyclic amino group optionally having at least one substituent together with the nitrogen atom to which they bind) or a salt thereof, and a pharmaceutical composition for use in the treatment of a Syk-related disease which comprises the nicotinamide derivative or a salt thereof.
